What Internal Door Work Covers in WA

Internal door work is one of the more visible improvements a household can make to a property, with new doors changing the look and feel of a room substantially while delivering practical benefits around acoustics, privacy and the daily experience of moving through the home. The category covers everything from a simple slab swap in an existing frame through to substantial works that change how a space is configured, such as converting hinged doorways to cavity sliders or replacing solid walls with French door openings to a garden.

The work sits across several adjacent trades depending on the scope. Straightforward door replacements are carpenter's work and run within standard residential trade rates. Larger projects involving structural modification may pull in framing carpentry, plaster work to make good around new openings, painting to refresh the surfaces around the new doors, and locksmith involvement for new hardware. The dedicated handyman services in WA guide covers the broader scope of small carpentry work that often sits alongside door projects.

Most internal door work in WA sits well below the twenty-thousand-dollar threshold that triggers building services registration under the Building Services Act 2011. A typical single-door replacement is a few hundred dollars and falls squarely within general residential trade scope. Larger projects involving substantial wall modification, multiple cavity slider installs, or work that forms part of a wider renovation may approach or exceed the threshold and require a registered building contractor. The dividing line is documented through the framework, and an honest tradesperson is clear about which side of the line the proposed work falls on.

The practical drivers for internal door work span several reasons. Tired or damaged doors that have outlived their service life make a property feel dated and worn, with a replacement set transforming the appearance of a home substantially for a modest investment. Layout changes such as converting a small bedroom into a study with French doors, or replacing a swing door with a cavity slider to free up wall space for furniture, address spatial considerations rather than just appearance. Acoustic and privacy upgrades using solid core doors in place of hollow core suit households with home offices, music rooms or shift workers needing quiet sleeping areas.

Hollow Core, Solid Core and Timber Doors

Hollow core doors are the most common residential internal door type and account for the bulk of doors fitted in Australian homes since the 1970s. The construction uses a thin face board (typically 3mm hardboard or MDF) bonded to a hollow cardboard honeycomb core, with timber stiles around the perimeter providing the structure for hinges and latches. Hollow core doors are light, inexpensive and easy to handle, which suits high-volume residential applications where cost matters and the household does not need acoustic separation or premium feel.

The trade-offs with hollow core are real. Sound passes through them readily, which means conversation in one room is audible in adjacent rooms. The light weight produces a flimsy feel when opening and closing the door. Hardware mounting is limited because the core is hollow, with screws needing to land in the perimeter stiles rather than anywhere across the face. Damage from impacts is harder to repair than on solid core, with a punched-through hollow core door generally needing replacement rather than repair.

Solid core doors use a dense particle board, MDF or composite core that delivers substantially better sound performance, a more solid feel when opening, and the ability to mount hardware anywhere across the face. The weight is two to three times that of an equivalent hollow core door, which means slightly more substantial hinges and frames are needed but the perceived quality is meaningfully higher. Solid core doors suit bedrooms where sound separation matters, home offices, primary living areas, and any application where the household wants the door to feel more substantial.

Solid timber doors are the premium category, using framed timber construction with solid timber panels, mouldings or glass infills. Heritage homes use timber doors as standard, with the original Victorian, Federation and post-war doors being solid timber construction throughout. Contemporary timber doors include modern panel designs and contemporary glass-and-timber configurations that suit current architectural styles. The cost is meaningfully higher than hollow or solid core, but the visual quality and longevity are correspondingly greater. A well-made timber door fitted properly lasts the life of the building.

Glass-panel doors, French doors and barn doors all sit in their own categories within the broader internal door scope. Glass-panel doors let light pass between rooms while maintaining some visual separation, with frosted, etched and clear glass options producing different privacy levels. French doors are paired hinged doors typically used as openings between living areas or to garden spaces, with the matching pair producing a substantial visual statement. Barn doors, a more recent residential trend, slide on exposed top tracks against the wall and suit contemporary and farmhouse aesthetics.

Hinged, Sliding, Bifold and Cavity Configurations

Hinged doors are the standard residential configuration and the simplest to install. The door swings on hinges fixed to one side of the frame, with a latch and handle on the opposite edge. Standard residential doors use three butt hinges per door on slab heights up to 2100mm, with four hinges typical on heavier doors or taller heights. Hinged doors need clearance to swing through their arc, which consumes floor space that some layouts cannot afford to lose.

Sliding doors run on a top-hung track that allows the door to slide sideways rather than swing. The configuration suits openings where the swing arc of a hinged door would conflict with furniture or where the visual lightness of a sliding door fits the space better. Top-hung tracks in current residential use are typically supplied by Brio (an Allegion brand) or Centor (an Australian premium brand), with quality varying meaningfully by track type and the smoothness of the action depending substantially on the track choice rather than the door itself.

Bifold doors fold against themselves on a top track, with two leaves hinged together that fold flush against the side of the opening when open. The configuration suits wardrobe openings, laundry closets and any application where the door needs to open clear of the opening but the household does not want a sliding-door slot to one side. The hinges between the leaves and the tracks at top and bottom need to be sound for smooth long-term operation, with cheap bifold sets often disappointing after a year of use as the alignment drifts.

Cavity sliders run inside the wall cavity rather than on an exposed track, with the door disappearing into a pocket frame built into the wall when open. The configuration is the most visually clean of the sliding options because no track is visible and the door completely vanishes when open. The trade-off is that the wall has to be built or modified to accommodate the pocket frame, which is straightforward in new construction or in stud-wall retrofits but substantially harder in WA's common double-brick construction.

Pocket doors are the historical predecessor to modern cavity sliders, with similar visual cleanness but using older mechanisms that did not always perform as well as current systems. Heritage Federation and Victorian homes sometimes have original pocket doors that have stopped working, with restoration being a specialist project worth the investment on a heritage property. Modern cavity slider systems from CS Cavity Sliders, Centor and similar manufacturers deliver substantially better long-term reliability than the original pocket doors and are the right answer for new work in this configuration.

Standard Australian Door Sizes

Australian residential internal doors use a small set of standard sizes that suit the bulk of construction. The most common standard is 820mm wide by 2040mm tall, which suits living areas, bedrooms and general internal doorways across most residential builds. The 720mm by 2040mm size suits bathrooms, laundries and ensuites where slightly narrower openings are common. The 870mm by 2040mm size suits wider openings including some main rooms and accessibility-rated doorways that need wheelchair clearance.

Taller doors at 2340mm and 2400mm heights are increasingly common in contemporary construction, with the taller proportion producing a more architectural feel than the standard 2040mm. Custom heights and widths are available but at a meaningful cost premium over the standard sizes, with manufacturers needing to produce a one-off door rather than picking from production stock. The household renovating a heritage property may encounter non-standard openings that require custom doors, with the heritage period preceding standardisation having used a wider range of sizes.

Accessibility considerations are worth thinking about for households with current or anticipated mobility needs. The 870mm standard width is the minimum recommended under AS 1428 for accessibility in residential settings, with wider 920mm doors better still for wheelchair access. The dedicated internal stair balustrade and handrail installation in WA guide covers related accessibility work, and households planning ahead for ageing in place benefit from coordinated design across doors, handrails and other accessibility features.

Frame dimensions are the other variable. Standard frames suit standard doors with a few millimetres of clearance around the door for free swing, while non-standard openings need either custom frames or modification of the opening to suit standard frames. The decision affects cost and timeline: standard sizes are available from stock and install quickly, while custom work requires lead time for manufacture and additional carpentry to fit. An honest carpenter at quote stage measures the existing opening and identifies whether standard or custom sizes are needed.

Brands - Hume, Corinthian and Beyond

Hume Doors is the largest Australian internal door manufacturer and supplies the bulk of the residential market through Bunnings, dedicated trade outlets and direct supply to builders. The Hume range covers hollow core flush, solid core flush, framed timber doors, French doors and various decorative styles, with standard sizes available from stock and quick turnaround on the volume items. The brand's distribution and competitive pricing make it the default for many WA residential projects.

Corinthian Doors is the other major Australian manufacturer in this category and offers a comparable range across hollow core, solid core and framed timber. The Corinthian product line is widely available through Bunnings alongside Hume and through dedicated trade outlets across Perth and regional WA. The two brands compete closely on price and feature, with the choice between them often coming down to which is in stock locally for the household's specific size and style requirements.

Premium and specialist brands sit above the major manufacturers. Trustile (US-based) offers high-end framed timber doors for architectural projects. Various specialist joinery suppliers across Perth produce custom doors for heritage restorations and one-off architectural specifications. Imported French doors and contemporary European designs come through specialist door suppliers serving the upper end of the market. The right brand for a particular project depends on the budget, the architectural intent and the timeline rather than there being a single answer that suits every case.

Cavity slider hardware comes from a separate category of manufacturers. CS Cavity Sliders is the Australian market leader for cavity slider pocket frames, with their products fitted in the majority of new cavity slider installs across the country. Centor is the Australian premium brand for sliding and bifold hardware, with engineering quality that justifies the price premium over budget alternatives. International brands such as Hettich and Hafele also supply sliding door hardware in the Australian market. The hardware quality affects the long-term operation of the door substantially, and a budget pocket frame can produce a sticking or jamming slider within a few years.

Hardware - Hinges, Handles and Locks

Door hardware is the part of the project most households take for granted and that most affects daily satisfaction. Quality hinges, smooth handles and reliable latches produce doors that operate cleanly for decades, while cheap hardware on a good door produces irritation every time the door is used. The hardware budget on an internal door project should reflect the long-term use the doors will receive, with premium handles costing perhaps fifty to one hundred and fifty dollars more per door than budget alternatives and being well worth the difference.

Standard residential hinges are 100mm by 75mm butt hinges, with three per door on slab heights up to 2100mm. Heavy doors and taller heights need four hinges or larger 100mm by 89mm hinges. Loose-pin hinges allow the door to be removed without unscrewing the hinges from the frame, which is convenient for furniture moves and for any work that needs the door off. Concealed hinges are increasingly common in contemporary residential work, with the hinge hidden inside the door edge and the architrave rather than being visible.

Door handle hardware comes in three main categories. Passage sets are simple latches without locking, suited to general internal doors where privacy is not needed. Privacy sets include a thumb-turn lock on the inside and an emergency release on the outside, suited to bathrooms, ensuites and bedrooms. Dummy sets are non-functional handles for doors that do not need to latch, such as one half of a French door pair where only one side actually operates the latch. The hardware mix on a typical home covers all three categories depending on the room.

Brand choices for residential door hardware span budget through premium. Lockwood (Allegion-owned) and Gainsborough are the volume Australian brands available through Bunnings and trade outlets, with reliable products at sensible price points. Yale and Schlage offer similar mid-market products. Pittella is the Australian premium brand made in Sydney, with handles that justify the price premium through engineering quality and design refinement. Sylvan covers the mid-to-upper market with European-style designs. The dedicated locksmith and lock repairs in WA guide explores the wider residential lock picture including the entry-level security work that sits alongside internal door hardware.

Latches and strike plates need to align correctly for the door to close cleanly. A door that catches on the strike, that does not latch on first closing, or that latches with substantial force needs adjustment of the strike position rather than acceptance of the imperfect operation. The carpenter doing a proper install adjusts the strike during commissioning so each door closes cleanly with light pressure, while one rushing the job leaves alignment issues for the household to live with. The few minutes of strike adjustment per door is the difference between doors that satisfy and doors that irritate.

Pre-Hung vs Slab Replacement

The decision between pre-hung sets and slab replacement affects scope, cost and the final result substantially. Pre-hung doors come from the manufacturer with the door already fitted in its frame, with hinges installed and the latch position prepared. The carpenter fits the complete pre-hung unit into the opening, plumbs and shims it level, and secures it to the surrounding framing. The work is faster than a slab replacement on a new frame and produces a more consistent result, since the door is matched to the frame at the factory.

Slab replacement is appropriate where the existing frame is in good condition and only the door itself needs replacing. The work involves removing the old door from the existing hinges, fitting a new door of matching size, marking and cutting the hinge mortises in the new door to match the existing frame positions, and fitting the new hinges and latch hardware. A properly fitted slab replacement looks identical to a pre-hung set but at substantially lower cost where the existing frame is sound.

The honest carpenter inspects the existing frame at quote stage and recommends slab or pre-hung depending on the frame condition. A frame that has dropped over the years, that has split timber, or that has hardware-pull damage may not be worth keeping and a pre-hung set is the right answer. A sound frame in good condition is worth keeping and a slab replacement is cheaper. The decision is genuine rather than driven by what suits the carpenter, and a household pressed toward pre-hung sets when slab replacement would work is being upsold.

The architrave around the door frame is a separate consideration. Pre-hung sets sometimes come with new architraves that match the new frame, while slab replacements leave the existing architraves in place. Where the household is also having interior painting done, the architraves can be repainted along with the surrounding walls, and the interior painting in WA guide details the wider interior paint scope that often runs alongside door projects.

Double Brick Construction and Cavity Sliders

Western Australia's housing stock includes a substantial share of double-brick construction, particularly in homes built before the 1990s in metropolitan Perth and the South West. Double brick produces solid, durable construction with excellent thermal mass, but it also creates specific challenges for internal door work that stud-wall construction does not face. The challenge is most apparent with cavity sliders, where the wall must accommodate a pocket frame for the door to disappear into when open.

Cavity slider installation in a stud wall is straightforward. The existing studs in the wall are removed in the area where the pocket frame will sit, the pocket frame is installed in the opening, plasterboard is patched around it, and the wall is restored to the original finish. The work runs a day or two depending on the complexity, and the result is a clean cavity slider that operates smoothly.

Cavity slider installation in a double-brick wall is substantially more involved and is sometimes simply not practical. The brick wall cannot accept a hidden pocket the way a stud wall can, with the alternatives being either a furred-out wall section with a stud-wall pocket in front of the brick (which consumes floor space and changes the wall thickness in that area), or a substantial brick modification that may not be structurally permissible. The honest tradesperson assesses the wall type at quote stage and recommends alternatives where cavity slider work in brick would be impractical or excessive.

The alternatives where a cavity slider is not practical include barn-style sliding doors on an exposed top track, which give similar functionality but visible hardware, and bifold doors which fold against the wall to one side and consume less wall space than a hinged swing. Some households accept the appearance trade-offs of these alternatives in exchange for avoiding the wall reconstruction that a true cavity slider in brick would require. The carpenter experienced with WA's construction patterns explains the options and lets the household choose rather than steering toward whichever option suits the carpenter's preferences.

Newer homes built since the 1990s in WA increasingly use stud-wall construction or brick veneer (brick exterior with stud interior walls), which makes cavity slider work much more practical than in older double-brick homes. The household considering substantial layout changes should know which construction type their property uses, and the carpenter at the quote should be able to identify the construction from a brief inspection.

Sound Transmission and Privacy

Sound transmission through internal doors matters more than households often appreciate at the time of choosing doors. Conversation in a living area carries through hollow core doors to adjacent bedrooms readily, with the sound reduction of a hollow core door being perhaps 17-20 dB compared with 28-32 dB for a solid core door of the same size. The practical effect is the difference between conversation being clearly intelligible through the door and being audible as muffled noise rather than identifiable speech.

Solid core doors in bedrooms, home offices and music rooms substantially improve the acoustic environment of the home. The cost premium over hollow core is perhaps fifty to two hundred dollars per door at the supply level, with installation similar between the two types. Households with shift workers, home schoolers, video conference users or anyone needing acoustic separation between rooms benefit from solid core doors throughout the affected areas.

Door seals and undercut clearance affect sound transmission alongside the door construction itself. A door with substantial gaps around its perimeter loses sound performance regardless of how solid the door itself is. Acoustic seals applied to the frame around the door and an undercut threshold seal at the bottom of the door close the air paths around the door perimeter and improve sound performance meaningfully. The work is straightforward and adds modest cost to a substantial door upgrade.

Multi-storey homes and apartments have additional acoustic considerations from the floor structures separating units, with door changes alone not addressing the broader sound performance of the building. The household frustrated by noise from upstairs neighbours in an apartment is not generally going to find the answer in better internal doors, with the solution sitting in the floor and ceiling structures that are outside the lot owner's authority. Coordination with glass repairs and window replacement on windows facing noisy streets sometimes produces more meaningful acoustic improvement than door upgrades alone.

Fire-Rated Doors in Apartments

Apartments and units within multi-residential buildings often have fire-rated doors at the entry to each unit, with the door forming part of the building's fire compartmentation under the National Construction Code. Fire-rated doors are heavy, specifically certified products with sealed perimeters and certified hardware, and they cannot be replaced with standard internal doors without compromising the building's fire compliance.

A lot owner planning to replace the entry door to an apartment needs to understand the fire rating requirement before specifying any replacement. The replacement door must carry the same or higher fire rating as the original, must be installed by a tradesperson familiar with fire-rated door work, and must use certified hardware including the closer that returns the door to closed automatically. A standard internal door fitted in place of a fire-rated door is non-compliant with the building's certification and may produce serious problems with insurance and strata if discovered.

Standards for fire-rated doors in residential buildings include AS 1530 for fire test methods and the certification requirements that flow from them. Information on building compliance is published through DMIRS and the building services framework. A strata council planning common-area or apartment-entry door work needs to ensure the replacement scope respects the building's certification, with the installer carrying the relevant experience and using certified product. Related coordinated trades on substantial renovation projects sometimes include garage door opener and automation installation for the external garage entry and home theatre installation for any AV equipment in adjacent rooms.

Heritage Doors - Restoration and Replacement

Heritage homes across Perth and regional WA carry original timber doors that are often a meaningful part of the property's character. Mount Lawley, North Perth, Subiaco, Fremantle, Cottesloe, Albany, York and similar heritage suburbs include substantial stocks of Federation and pre-war homes where the original doors remain in place. The doors are typically solid timber, framed construction with mouldings, leadlight or coloured glass panels, and hardware that reflects the era's standards rather than current production.

Restoration is often the right answer where original doors are still in place and functional. The work covers stripping back accumulated paint to reveal the original timber, sanding and repair of any damaged sections, replacement of damaged glass panels with appropriate period-correct glass, and refinishing with a finish appropriate to the period. A properly restored heritage door looks dramatically better than the same door buried under decades of paint and adds meaningful value to the heritage property.

Replacement is sometimes necessary where the original door is too damaged to restore or where the household needs a new door for an opening that did not previously have one. Custom heritage doors from specialist joiners reproduce the period style and proportions, with the cost being meaningfully higher than standard production doors but the result being appropriate to the heritage building. A new door in a heritage style fitted into a heritage opening should match the rest of the home's door specification rather than introducing a contemporary look in a heritage context.

Heritage controls in some Perth suburbs may affect what is permissible. The local council may have a position on changes to visible exterior heritage elements, including the entry door which is often the most visible heritage feature from the street. Internal doors are generally less restricted, but a substantial alteration in a heritage-listed property may need approval before work proceeds. Coordination with house painting and interior painting work on heritage properties lets the painter address any cosmetic finishing around new or restored doors as part of a coordinated project.

Strata Properties and Internal Door Work

Strata properties carry an additional governance layer for door work that affects how projects run. Most internal doors within an apartment or townhouse are lot property and can be replaced by the lot owner without strata involvement, while the entry door of the unit is sometimes treated differently because it sits between lot property and common property and may be part of the building's fire compartmentation.

The Strata Titles Act 1985 provides the WA framework, and the scheme's by-laws set the specific arrangements for each building. A lot owner planning substantial door work should review the by-laws and confirm with the strata council whether any approvals are needed before commissioning. Most schemes do not require approval for routine internal door replacement, but heritage buildings, high-end developments and buildings with strong aesthetic uniformity may have specific requirements that affect entry doors and any visible elements.

Information on the WA strata framework is available through the Government of Western Australia portal. The lot owner whose work is purely within the apartment can generally proceed without strata involvement, while any work touching common areas or the building's fire compliance needs to go through the owners corporation. The honest tradesperson familiar with strata work flags this at the quote stage and waits for the lot owner to confirm the engagement is correctly authorised.

Painting Coordination

Internal door projects coordinate naturally with painting work and the household benefits from sequencing the two together rather than independently. New doors typically come unfinished or in a primer-only state, with the household responsible for the final finish coats. Painting the doors after install while the painter is on site for interior work produces a coordinated finish that matches the surrounding trim and architraves.

The sequencing matters. Doors are best painted before final hardware is fitted, since paint runs and brush marks around hinges and handles are difficult to clean up after installation. The carpenter fits the doors and frames, removes the doors for painting if needed, the painter finishes the doors and surrounding trim, and the doors return to their hinges with the final hardware fitted last. This sequence produces the cleanest result but requires the trades to be available in the right order.

Where painting is happening as a separate project after door installation, the household should arrange for the doors to be primed but not finished by the door supplier or installer. Primed doors take topcoat readily and produce a uniform finish, while pre-finished doors from the manufacturer may not match the colour the household wants for the rest of the trim. The honest carpenter discusses this at quote stage rather than delivering pre-finished doors that the household then needs to repaint to match.

Wall Make-Good After Door Work

Substantial door work that involves modifying openings, removing existing frames or installing cavity sliders produces damage to the surrounding wall that needs to be made good before painting can produce a clean finish. The make-good work covers patching plasterboard around new openings, replacing damaged sections of architrave, and finishing any masonry work to a paintable standard. The carpenter completing the door install should leave the surrounding wall in a state ready for painting, even if the painting itself is a separate trade.

Plaster patching around new openings uses appropriate plasterboard compounds and may need taping over joints for stability. The patched section needs to be sanded flush with the surrounding wall, primed and then painted with the surrounding wall colour. A poorly made-good patch shows through the paint as a visible shadow or texture difference, which means the make-good work needs to be done properly to avoid disappointing the finished appearance.

Heavy-handed make-good work that damages more than it repairs is sometimes a sign of an inexperienced operator. A carpenter who needs to chase out substantial wall sections to fit a new door, who damages tiles or floor finishes during the work, or who leaves substantial mess that the household has to clean up before painting can start is not delivering the standard the household is paying for. An honest assessment at quote stage identifies what make-good will be needed and prices the work accordingly.

Asbestos in Older Door Openings

Homes built before the mid-1980s sometimes have asbestos materials around door openings, with internal wall sheeting in some homes containing asbestos. Modifying door openings in these homes requires identification of the materials before any aggressive work, since cutting or breaking asbestos-containing sheets releases fibres that are dangerous to breathe.

The proper handling involves identifying the materials before work, working around intact materials carefully where possible, and engaging a licensed asbestos removal specialist for any disturbance that cannot be avoided. The additional cost of proper handling is real but the consequences of unmanaged asbestos exposure are not something to negotiate away. Information on the WA framework for asbestos handling is published by WorkSafe WA.

A tradesperson working on an older home should raise asbestos as a consideration at the quote stage and propose appropriate handling in the scope. A tradesperson who is dismissive of the issue, who proposes aggressive cutting without checking the materials, or who claims asbestos is not a real concern in residential door work is offering work that does not meet current safety expectations.

Commissioning and Final Checks

A properly completed internal door project ends with each door operating cleanly through its full range. The door closes with light pressure, the latch engages on first closing, the hardware operates without binding, hinges do not squeak, and the door clears the floor and frame without rubbing. Achieving this on each door takes a few minutes of commissioning per door, with the carpenter adjusting strike plates, hinge alignment and floor clearance to produce the final result. Where the door work is part of a wider renovation that includes electrical services for new lighting or switches near the door positions, coordination between the carpenter and the licensed electrician produces a tidier overall outcome.

The walk-through inspection at the end of the project covers each door installed, with the household and the carpenter operating each one to confirm satisfactory operation. Any items needing further adjustment are identified and addressed before sign-off, with the carpenter willing to return briefly if any issue emerges in the first weeks of use as the doors settle into the surrounding structure. Documentation covers the doors fitted, the hardware specifications, the manufacturer warranties and the carpenter's workmanship cover for the project.

What to Look Out For

Watch for tradespeople who underquote the work required for cavity slider installation in double-brick walls. Cavity sliders in brick walls are substantially more involved than the same work in stud walls, and a quote that does not reflect the additional scope is either based on the wrong assumption about the wall type or is going to over-run during the work. The honest quote identifies the wall type and reflects the appropriate scope in the price, with the household ending up with the work they were quoted rather than discovering surprises during the project.

Be cautious of quotes that skip hardware quality. Cheap hinges, basic budget latches and budget handle sets produce doors that irritate every time they are used, while the cost premium for mid-market or better hardware is modest compared with the long-term satisfaction. A tradesperson who specifies budget hardware on substantial doors is offering a finished result that the household will regret, and asking for an upgrade to better hardware at quote stage is generally well worth it.

Treat dismissive responses about fire-rated doors in apartment buildings with appropriate scrutiny. Fire-rated doors are certified products with specific performance requirements, and a tradesperson who proposes to replace a fire-rated entry door with a standard internal door is offering work that compromises the building's fire compliance. The right tradesperson knows the difference and specifies the appropriate certified product, even where the standard product would be cheaper.

Look out for surprises around make-good work after substantial door modifications. The work of patching plasterboard, repairing architraves and finishing masonry around new openings is part of a complete door project, not an extra to be added later. A quote that covers only the door and hardware and leaves the household to arrange make-good separately is incomplete, with the household either ending up with visible damage around the new doors or paying extra to have it fixed by another tradesperson.

Confirm the scope on paper before work starts. The doors being supplied with brand and model numbers, the hardware specification, the make-good arrangement, the workmanship warranty and the expected timeline should all be documented before any work commits. A modest deposit against an itemised written quote, with progress payments tied to completed work, is the standard arrangement. A tradesperson who treats documentation as optional, who asks for substantial upfront payment, or who pushes for verbal agreement is signalling a casual approach that established operators do not share.

How to Get Useful Quotes

A clear job description gives tradespeople what they need to quote accurately. The description should cover the number of doors involved, the room each door serves, whether the existing frames are being reused or new frames fitted, any preferences about door type (hollow core, solid core, timber) and configuration (hinged, sliding, bifold, cavity), any hardware preferences and brand preferences, and any heritage or fire-rating considerations on older buildings or apartments. Photos of each door opening from both sides help the carpenter scope the visit and identify any specific concerns.

A site visit is essential for any substantial work involving cavity sliders, opening modifications, multiple doors or any project where the existing framing condition affects the scope. The carpenter sees the actual wall construction, the existing frames, the surrounding finishes and any access considerations, and quotes accurately rather than estimating from descriptions alone. Established tradespeople offer site visits without charge for prospective work within their normal area.

Verify each quoting tradesperson's public liability insurance, ask about their experience with the specific door type being installed (particularly cavity sliders, French doors, bifolds and any heritage work), and ask about their make-good approach for any wall modifications. An honest tradesperson welcomes the verification step rather than treating it as intrusive, and the household ends up with confidence in the operator before any commitment is made.

Posting a clear job description through The Quote Yard reaches several insured WA carpenters at once and gathers comparable quotes without chasing each one individually. Internal door work often sits alongside other property work the household is planning. If the property is also planning a handyman services visit for various small items, a locksmith visit for related lock work, an interior painting project across the same rooms, a house cleaning service after the work is complete, an internal stair balustrade installation project on the same property, a glass repairs and window replacement piece of work, or an IKEA furniture assembly visit, describing the broader picture in one brief lets the household plan the trades in proper sequence.

Insurance, Warranty and Australian Consumer Law

Public liability insurance is the household's protection during the work and covers any damage the tradesperson causes during the visit. A current certificate of currency should be available before work begins, with five to twenty million dollars of cover being typical for residential carpenters.

Product warranties on internal doors and hardware vary by brand and tier. Hume and Corinthian doors typically carry one to two years from the manufacturer for hollow core and solid core products, with longer warranties on solid timber and premium ranges. Hardware warranties from Lockwood, Gainsborough, Pittella and other manufacturers cover defects in materials and workmanship for periods that vary from one year on budget items through to ten years on premium handles. The household keeps the product paperwork along with the carpenter's workmanship cover for the full picture.

Workmanship cover from the carpenter is generally twelve months for the install itself, with the carpenter returning at no charge to address any defects in the work that emerge during the period. A door that has dropped in its frame, hardware that has loosened, or any issue arising from the install rather than from product defects should be addressed by the original installer without dispute. The honest tradesperson stands behind their work for the warranty period without argument.

Statutory guarantees under the Australian Consumer Law sit alongside any express warranty. Information on consumer rights is published by Consumer Protection WA and the ACCC.
