Iron Gate and Fence Welding Repairs NSW 2026 - Get Quotes
Most so called wrought iron in New South Wales suburbs is actually mild steel, bent into scrolls and welded together from the 1950s onward, and it welds easily. The ironwork on Victorian and Federation homes in Paddington, Glebe, Balmain, Newtown and inner Newcastle is often something else entirely. Much of it is cast iron, which is brittle and cracks rather than bends, and some is true wrought iron, which behaves differently again. Welding the wrong way on either can destroy an original piece that cannot be replaced easily. Old ironwork is also usually coated in lead based paint, which must be handled carefully before any grinding or heating. So the first step in any repair is working out what the metal is. Small rust repairs and rehung gates cost a few hundred dollars, while full heritage restoration is priced by the metre. In inner Sydney and older country towns, heritage controls can also affect what changes are allowed, and rusting iron set into sandstone plinths often cracks the stone as well. Getting the metal identified, the paint tested and the stonework assessed before quoting avoids surprises once work starts.

At a Glance - Which Iron Have You Got
| Material | Where You Find It | How It Fails | Can It Be Welded | Usual Repair |
|---|---|---|---|---|
| Mild steel, wrought iron style | Suburban gates and fences, 1950s onward | Rusts at joints and bottom rails | Yes, easily | Cut out and weld in new steel |
| Cast iron | Victorian lace, panels, finials, posts | Cracks and snaps | Difficult, specialist methods | Braze, stitch or recast |
| True wrought iron | Older bars, rails and gates | Rust splits along the grain | With care and experience | Forge weld or careful arc weld |
| Hollow steel tube | Modern budget gates | Rusts from inside | Yes, if not rusted thin | Replace section |
| Galvanized steel | Newer and restored work | Coating damage, then rust | Yes, with fume control | Weld, then zinc repair |
| Aluminium, iron look | Modern powder coated fences | Broken welds, bent rails | Yes, specialist | TIG repair, recoat |
Telling Cast Iron, Wrought Iron and Steel Apart
The metal decides the repair method, so a good tradesperson identifies it before quoting, and owners can often make a reasonable guess themselves.
Cast iron is poured molten into sand moulds, so cast pieces have the look of a moulding. Decorative lace panels, finials, rosettes, post caps and the ornate posts on Victorian verandahs are usually cast. Look for thick, slightly rounded sections, fine repeating detail and sometimes the rough texture of the mould on hidden faces. Broken cast iron shows a grey, crystalline fracture and snaps rather than bends. Wrought iron was hammered and rolled from a softer, fibrous metal, and old bars sometimes show a woody grain where rust has opened them up along their length. It bends before it breaks.
Mild steel is what nearly all gates and fences have been made from since the middle of the twentieth century, including most scrolled wrought iron style work in the suburbs. It has crisp, uniform bar and tube sections, visible arc welds at the joints, and often machine bent scrolls that repeat exactly. A magnet sticks to all three, so it will not help, but the look of the joints usually settles it. Riveted or collared joints and hammered ends point to old work, while arc welded joints mean steel. Where a property is old and the ironwork might be original, ask the tradesperson to confirm what it is before anyone starts grinding. General steel gate repairs are straightforward work for a welding workshop, while original cast and wrought work needs someone with heritage experience.
Where Iron and Steel Fences Rust First
Rust on gates and fences follows water. Wherever water sits for long, rust starts. Bottom rails collect rain, leaves and garden soil and stay damp for days after a storm. Posts rust where they enter concrete, masonry or the ground, because water pools in the gap and the coating wears through. Joints between bars trap moisture in the tiny crevice where they meet. Keeping garden beds and sprinklers away from the base of the fence slows all of these problems considerably.
On hollow tube gates, water gets inside through unsealed ends or drilled holes and rusts the tube from the inside out, often until it can be poked through with a screwdriver. The worst damage is often hidden. A fence that looks sound from the street may have bottom rails rusted through behind a hedge, or posts that have lost most of their steel just below the paint. Tapping along rails with a screwdriver handle finds thin spots quickly, and bubbling paint, orange streaks and flaking scale point to where to look.
Repairs for mild steel are straightforward, and any competent welding workshop can handle them. Most suburban fences fall into this group. Rusted sections are cut out and new steel of the same size is welded in, the area is cleaned back to bright metal, primed and painted. Where the bottom rail is rusted along its whole length, replacing it entirely is usually cheaper than patching, and where every post is rusted at ground level, the fence may be better lifted, repaired in a workshop and reset on new footings. Brick piers and walls that hold the ironwork often need attention at the same time, and brick fence and wall builders can rebuild cracked or leaning piers.
| Rust Location | Why It Happens | Usual Repair |
|---|---|---|
| Bottom rail | Water, leaves and soil collect | Replace rail section |
| Post at ground or concrete | Water pools in the gap | Cut out, plate or new post |
| Bar and rail joints | Moisture in the crevice | Clean out, reweld, seal |
| Hollow tube gates | Water inside the tube | Replace tube section |
| Post set into stone or brick | Rust expands and cracks masonry | Remove, repair, reset properly |
| Gate hinge and latch area | Wear breaks the coating | New hinges, repaint regularly |
Deal With Lead Paint Before Any Grinding
Paint on ironwork from before about 1970 very often contains lead, and older gates and fences have usually been painted many times over the decades. The layers underneath the current topcoat can be heavily leaded even when the most recent coat is not. Grinding, wire brushing, sanding, abrasive blasting or heating leaded paint releases fine dust and fumes that are toxic, particularly for young children and pregnant women, and the dust settles into garden soil, paving and nearby homes. Testing comes first, where simple test kits give a quick indication, and laboratory testing of paint chips gives a definite answer. If lead is present, the paint must be removed with methods that control dust and waste, such as wet scraping, chemical strippers or contained blasting in a workshop, and the waste disposed of properly.
Welding directly through leaded paint is not acceptable, because the heat vaporises the lead. Guidance on managing lead paint in homes is set out in AS/NZS 4361.2, and the NSW EPA publishes advice for householders and tradespeople. For testing and safe removal before metalwork starts, lead paint testing and removal specialists can take care of that stage and leave the ironwork ready for repair. Children and pregnant women should stay well away from the work area until the lead paint has been removed and the site cleaned.
| Paint Removal Method | Suitable for Lead Paint | Notes |
|---|---|---|
| Dry grinding or sanding on site | No | Spreads toxic dust |
| Wet scraping | Yes | Slow, suits small areas |
| Chemical stripper | Yes, with care | Collect sludge as lead waste |
| Contained abrasive blasting | Yes, in a controlled facility | Usually off site |
| Open flame or torch | No | Vaporises lead |
| Welding through the paint | No | Remove paint from the area first |
Why Cast Iron Resists Ordinary Welding
Plenty of cast iron finials and lace panels have been ruined by well meaning repairs, and understanding the metal explains why.
Cast iron contains far more carbon than steel, much of it as flakes of graphite, which is what makes it easy to pour into intricate moulds and also what makes it brittle. When a welding arc heats one small area, that spot expands while the surrounding cold metal does not, and as the weld cools and shrinks, the stress often cracks the casting beside the weld. The carbon also mixes into the weld metal and makes it hard and brittle. Old cast iron that has sat outdoors for a century adds rust, paint and absorbed contamination to the problem. Specialists use several approaches. Preheating the whole piece slowly, welding in short runs with nickel based electrodes designed for cast iron, and cooling it slowly, sometimes buried in insulation, reduces cracking. Brazing, which joins the parts with a bronze filler at a lower temperature without melting the iron, is a common and gentler option for decorative pieces. Cold metal stitching, where the crack is drilled and locked with interlocking metal keys and threaded pins, repairs thicker castings such as posts and bases without heat at all. Epoxy and resin fillers suit only small cosmetic gaps. The right method depends on the size of the piece, the load on it and whether it is visible, so ask the tradesperson which approach they propose and why before work begins. Old homes with cracked cast iron columns carrying verandah roofs should be looked at structurally first, and a structural inspection can confirm whether the post is doing more than decorating.
Broken Finials, Lace and Castings
Cast iron fences and gates across Sydney's older suburbs often have missing finials, broken spear points, cracked rosettes and gaps in the lace panels where a piece has snapped off. Replacements are more available than many owners expect. Several Australian foundries and heritage suppliers produce reproduction castings in traditional patterns, and a good match can often be found for common designs. For less common patterns, a foundry can make a new casting from an existing piece. The surviving piece is used to make a mould pattern, sometimes repaired or reshaped first, and new castings are poured from it. This costs more for a single piece, but it becomes reasonable when several are needed, while salvaged originals from demolition yards are another source, though sizes and patterns vary.
Fitting is usually done by drilling and pinning, bolting, brazing or careful welding with cast iron methods, depending on how the original was fixed. The aim is a repair that holds and looks as though nothing happened. Iron lace on verandahs and balconies is repaired the same way, and replacement verandah structures that include decorative iron are built by patio and verandah specialists with heritage experience. Original castings that are only cracked, not missing, are usually worth keeping and repairing instead of replacing.
Sagging, Dragging and Swinging Gates
A gate that drags on the path is one of the most common complaints. The cause is usually worn or broken hinges, a hinge post that has rusted or leaned, or a gate frame that has twisted as joints weakened. On older gates, the hinges are often pintles, pins set into the post or pier that the gate hangs on, and when those rust or the stone around them cracks, the gate drops. Repairs start with the post. If the post or pier has moved, straightening the gate alone will not last. Once the post is sound, the welder can fit new hinges or pintles, reweld cracked frame joints, add a diagonal brace to stop sagging and adjust the latch.
Heavy driveway gates bring more load. Width multiplies the strain on every hinge. Wide swinging gates put enormous leverage on their hinges, and older ones were often built without enough bracing. Fitting a wheel or converting to a sliding gate can solve persistent sagging, although sliding conversions need space along the fence line. Automated gates need the motor and settings checked after any structural repair, which automatic gate installers handle.
| Gate Symptom | Likely Cause | Repair |
|---|---|---|
| Drags on the path | Worn hinges or dropped pintles | New hinges, reset pintles |
| Latch no longer lines up | Post leaning or frame twisted | Straighten post, brace frame |
| Gate swings open by itself | Post out of plumb | Replumb post, adjust hinges |
| Rattles and flexes | Cracked frame joints | Reweld, add bracing |
| Heavy driveway gate sagging | Too little bracing for width | Brace, add wheel or convert |
| Cracked stone around pintle | Rusting iron expanding | Remove iron, repair stone, reset |
When an Old Iron Fence Is Part of a Pool Barrier
Decorative iron fences and gates were never designed as pool barriers, yet on some older properties a section of iron fence forms part of the fence around a swimming pool. That creates a problem. Pool barriers in New South Wales must comply with the Swimming Pools Act and the pool barrier standard it references, AS 1926.1, which sets rules for height, gaps between vertical bars, the space under the fence, horizontal members that could be used as footholds, and a non climbable zone around the barrier. Scrolls, rings, horizontal rails and decorative castings on old ironwork often give a small child exactly the footholds and gaps the standard is designed to prevent. Gates on a pool barrier must also swing outward from the pool, and self close and self latch from any position. If you are repairing an iron fence that forms part of a pool barrier, the repair has to leave the barrier compliant, which may mean adding infill mesh or panels behind decorative sections, changing the gate hardware, or replacing that part of the fence with a compliant design while keeping the heritage front fence as it is. Properties with pools that are sold or leased in New South Wales generally need a certificate of compliance or a certificate of non compliance, and a barrier that fails inspection has to be fixed. Before starting work on any fence near a pool, ask whether it forms part of the barrier, and have the finished work checked. Compliance inspections and pool barrier repairs are handled by pool fence repairs and compliance specialists.
Record the Fence Before Anything Comes Apart
Old iron fences are often unique, and once a panel is removed or a casting breaks, the details that made it right can be lost. A few minutes recording the fence before work starts protects it. Photograph the full length of the fence from the street and from inside the property, then each panel and gate straight on, with a tape measure visible for scale. Photograph every distinctive detail up close, including finials, spear points, rosettes, scrolls, lace, hinges, latches and the way bars meet rails and posts. Note the spacing between bars, the height of the fence above the plinth and the width of each gate opening. Number the panels on a simple sketch so they can go back in the same order, because old fences are rarely identical from bay to bay. Keep any broken or loose pieces, even small fragments, since a foundry can often use them to make a pattern, and a restorer can match profiles from them. Look for any maker's marks or foundry names on castings, which help identify the pattern and sometimes the era. Photograph the plinth stones and piers as well, showing cracks, missing mortar and where each bar enters the stone. Record the existing colour, and if you can, scrape a tiny area in a hidden spot to see earlier paint layers, remembering to treat old paint as lead containing. Share all of this with the tradesperson and with the council heritage adviser if the property is listed or in a conservation area. The record also helps if insurance is involved after storm or vehicle damage. Exterior repainting of the house to match a restored fence is quoted by exterior house painting businesses.
Sandstone Plinths, Brick Piers and Rust Jacking
Many of the finest old iron fences in Sydney sit on sandstone plinths, with bars leaded or cemented into holes drilled in the stone and gates hung from pintles set into sandstone or brick piers. Over a century, water gets into those holes, the iron rusts, and rust takes up several times the volume of the original iron. The expanding rust splits the stone, a process known as rust jacking, and the result is cracked or broken plinth stones, loose bars and dropping gates. Repairing it properly means dealing with both the iron and the stone. The corroded iron is cut out or removed, cleaned or replaced, and the stone is repaired or pieced in by a stonemason. The stonework often takes longer than the metalwork, so ask both trades for realistic timeframes before the fence comes apart.
The iron is then reset in a way that keeps water out, traditionally with molten lead poured around the bar and now often with suitable non corroding sleeves and fixings. Setting iron straight back into cement mortar usually repeats the problem. The metalworker and stonemason should work together, as neither can fix it alone. Sandstone repairs, piecing in and replacement copings are the work of stone masonry specialists, and brickwork around piers is repointed by brick repair and repointing tradespeople.
Heritage Items and Conservation Areas
A large share of Sydney's inner suburbs, and parts of Newcastle, Parramatta, Goulburn, Bathurst and many country towns, sit within heritage conservation areas listed in the local council's planning controls, and some individual homes and fences are listed heritage items. Front fences and gates are often singled out in those controls, because they shape the character of the street. Maintenance and like for like repairs are generally treated differently from changes. Repairing a rusted rail with matching steel, replacing a missing finial with a matching casting or repainting in the existing colour is usually straightforward.
Replacing an original iron fence with a new design, changing its height, adding solid infill for privacy, or swapping cast iron for modern steel pickets can need council consent. The rules vary from council to council, so ask the council heritage adviser or check the local controls before planning anything beyond a repair, and use the NSW Planning Portal to find the planning controls that apply to the property. Heritage experience matters in the tradesperson too. Someone who understands traditional joints, castings, finishes and colours will usually produce a repair that sits comfortably with the rest of the house. Period appropriate colours for fences and trims are a common part of heritage paint schemes, and heritage home painting costs are worth understanding before choosing a finish.
Castings, Coatings and Suppliers Behind Good Ironwork
Good iron repairs rely on the right replacement parts and finishes as much as on the welding, and a few types of supplier come up repeatedly.
Reproduction cast iron finials, spear points, rosettes, lace panels and post caps are produced by Australian foundries and heritage hardware suppliers, several of which hold large collections of traditional patterns and can match common Victorian and Federation designs. Architectural salvage yards in Sydney and regional centres stock original castings recovered from demolitions. Hot dip galvanizing for restored steel is carried out by businesses such as Industrial Galvanizers. For paint, Dulux, Wattyl and Taubmans all offer metal primers and enamels, and heritage colour ranges are available from companies including Porter's Paints and the major brands' heritage collections. Abrasive blasting is usually done by specialist blasting businesses in industrial areas, which have the containment needed for lead paint. A few questions help. Ask where replacement castings will come from and whether they match the originals in pattern and size. Ask whether blasting will be done in a contained facility where lead paint is present. And ask for the full coating specification, including primer, number of coats and colour, so the finish can be matched later. Old cast iron guttering and rainwater heads on the same house are often restored with similar methods, and heritage gutter restoration specialists deal with those.
| Proposed Work | Usual Treatment | Check First |
|---|---|---|
| Like for like rust repair | Generally maintenance | Matching materials |
| Replacing missing castings | Generally maintenance | Matching pattern |
| Repainting in the same colour | Generally maintenance | Lead paint rules |
| New colour scheme | May need advice | Council heritage controls |
| New fence of a different design | Often needs consent | Council before ordering |
| Adding solid infill or height | Often needs consent | Council before ordering |
Full Restoration of an Old Fence or Gate
When rust, missing pieces and layers of old paint have piled up, patch repairs stop making sense and a full restoration becomes the better option. The usual sequence is to test for lead, then carefully remove the fence and gates, photographing and labelling every panel so it goes back exactly as it came off. In the workshop, the ironwork is stripped by contained abrasive blasting or chemical stripping, which reveals the true condition of the metal and every hidden crack. Repairs follow once the metal is bare, as rusted steel is cut out and replaced, cast pieces are brazed, stitched or recast, missing finials and castings are sourced, and joints are rebuilt. Many restorers then hot dip galvanize the steel parts, which gives decades of rust protection, although cast iron components usually need a different treatment, and a zinc rich primer and a durable paint system finish the job.
While the ironwork is in the workshop, the stonemason or bricklayer repairs the plinth and piers. Reinstallation sets the fence on sound footings or in properly prepared stone, with drainage and fixings that will not rust jack again. Restoration is typically priced per lineal metre, commonly $400 to $1,200 depending on the detail, the amount of casting work and the masonry involved. It usually takes several weeks, so a temporary fence may be needed where security or pool safety is a concern.
Neighbours, Councils and the Rules That Apply
Fence work in New South Wales can involve neighbours, council and several safety rules at once, so it helps to know which apply to your job.
Where the iron fence runs along a boundary between two properties, the Dividing Fences Act 1991 applies, and neighbours generally share the cost of a sufficient dividing fence, with a notice process for proposing work and resolving disagreements. Front fences facing the street are not dividing fences under the Act, so the owner usually bears the cost alone. Heritage items and properties in conservation areas are subject to the local council's planning controls, and changes to their fences may need consent. Any section that doubles as a pool barrier has to meet AS 1926.1 under the Swimming Pools Act. Lead paint must be managed to protect health and the environment, with guidance in AS/NZS 4361.2. Installing a new fence or gate as part of a residential building contract over $5,000 including labour and materials needs a contractor licence from NSW Fair Trading. Welding and blasting businesses must manage fume, dust, fire and noise risks under work health and safety law. For owners, the useful steps are to talk to the neighbour early on boundary fences, check heritage controls before any change in design, confirm whether the fence forms part of a pool barrier, and ask the tradesperson how lead paint and waste will be handled. Information on dividing fences, licensing and consumer rights is available from NSW Fair Trading.
| Ask Every Tradesperson | Why It Matters | A Good Answer |
|---|---|---|
| What metal is this | Decides the method | Cast, wrought or steel, identified |
| Will you test for lead | Old paint is usually leaded | Yes, before any grinding |
| How will you repair cast pieces | Ordinary welding cracks them | Brazing, stitching or specialist welding |
| How will posts be reset | Rust jacking cracks stone | Sealed, non corroding detail |
| What coating system will you use | Decides how long it lasts | Named primer and topcoat, or galvanizing |
| Have you worked on heritage fences | Traditional detail matters | Examples provided |
Storm, Tree and Vehicle Damage
Front fences on busy streets and tight driveways get hit by cars more often than owners would like, and storms regularly bring branches or whole trees down across fences in leafy suburbs. Damage to mild steel is usually repairable by straightening, cutting out bent sections and welding in new steel. Damage to cast iron is harder, since cast pieces snap instead of bending, and broken sections may need brazing, stitching or new castings. Make the site safe first, particularly if the fence protects a pool or keeps children and pets in. A temporary panel of mesh fencing, hired for a few weeks, keeps the property secure while castings are sourced or the damaged section is repaired in a workshop.
Photograph the damage from several angles before anything is moved, and keep every broken piece, however small, as fragments help match or recreate castings. Where a vehicle caused the damage, the driver's insurer may cover the repair, and where a storm did, home insurance often does. Insurers usually want a written quote that itemises the work, so ask the metalworker for one. Where the storm damaged roofs, gutters or walls as well, a storm damage repair contractor can coordinate the wider job.
New Gates and Fences in a Traditional Style
Where the old fence is beyond saving, or a modern home wants a traditional look, new iron style gates and fences are made from mild steel bar, tube and cast components. Custom pedestrian gates typically cost $1,500 to $6,000 and driveway gates $3,000 to $10,000, depending on size, detail and automation. Galvanizing before painting is well worth the extra cost for anything outdoors, and particularly near the coast. Good reproduction work starts from the house itself. Photographs of original fences in the same street, historic photos of the property and surviving pieces all help a fabricator design something that suits the period.
Modern steel made to traditional proportions, with cast finials and properly detailed joints, looks far better than generic scrolled designs. Standard steel, aluminium and timber options for simpler homes are quoted by fence and gate installation businesses. A fabricator who has built period style gates before can usually show photographs of past work, which helps judge whether their style suits the house. Asking for a scale drawing before fabrication starts gives you a chance to adjust heights, spacing and details while changes are still cheap.
Repair, Restore or Replace the Fence
Iron fences sit on a spectrum from a quick weld to complete replacement, and the right choice depends on the metal, its condition and what the property needs. Original cast iron and wrought iron on a period home are almost always worth keeping. They are part of the character of the house and the street, they are often protected by heritage controls, and good reproductions cost more than most people expect. Repairing and restoring them, even when it is slow, usually adds value. Mild steel fences from the mid twentieth century onward are more straightforward. If the rust is limited to bottom rails, a few joints and post bases, repairs and repainting will give many more years. If rust has spread through most rails, hollow tubes have rusted from inside and posts are failing along the whole run, a new fence can cost less than repairing every section, and it can be galvanized from the start. Budget steel fences of thin tube are rarely worth extensive repair. Security and safety needs also matter. A fence that must work as a pool barrier, or a gate that needs to be automated, may be easier to replace with a compliant, purpose built design than to adapt. On heritage properties, replacement of original fabric may need consent, so check before deciding. Ask the tradesperson for both options where the fence is borderline, with prices for patch repairs, full restoration and replacement side by side. For standard new fences in steel, aluminium or timber, fence and gate installation businesses can quote alongside the metalworker.
Regional Considerations Across New South Wales
Inner Sydney has the largest concentration of original Victorian and Federation ironwork in the state, in suburbs such as Paddington, Glebe, Balmain, Surry Hills, Redfern, Newtown, Annandale and Petersham. Heritage controls are common there, and sandstone plinths and cast iron are the norm. Middle ring suburbs have more mid century and later mild steel fences, where straightforward welding repairs are usual. Inner Newcastle, Maitland and many country towns, including Bathurst, Goulburn, Orange, Mudgee and Armidale, have fine old ironwork on houses, churches and public buildings, and sometimes strong heritage controls. Coastal homes see faster corrosion from salt spray, so galvanizing and a high quality paint system make a big difference there.
Cooler, wetter tablelands towns can see moisture sitting on ironwork for long periods, which speeds rust at joints. Paint breaks down faster there too. Timber gates and fences on older cottages need different trades, and timber fence and gate repair specialists handle those. Heritage advisers at councils across the state are a useful free resource for owners unsure what their ironwork is or how it should be treated. Local historical societies and council archives sometimes hold old photographs showing what a property's original fence looked like.
| Area | Typical Ironwork | Practical Note |
|---|---|---|
| Inner Sydney terraces and villas | Cast iron, sandstone plinths | Heritage controls, lead paint |
| Middle ring Sydney suburbs | Mild steel scrolled fences | Standard welding repairs |
| Inner Newcastle and Maitland | Victorian and Federation iron | Heritage experience helps |
| Historic country towns | Cast iron on homes and churches | Council heritage advisers |
| Coastal suburbs and towns | Steel and cast iron | Galvanize, repaint regularly |
| Tablelands towns | Older iron fences | Damp speeds joint rust |
| Item | Cost | Note |
|---|---|---|
| Rust repair on a panel | $150 - $500 | Mild steel |
| Gate rehang or new hinges | $200 - $600 | Post must be sound |
| Cast iron repair | $250 - $1,200 | Brazing or stitching |
| Replacement castings | $15 - $80 each | Plus fitting |
| Full restoration | $400 - $1,200 per metre | Blast, repair, coat, reset |
| New custom driveway gate | $3,000 - $10,000 | Galvanize before painting |
Keeping Ironwork Painted and Rust Free
Paint is what keeps iron and steel fences alive between repairs, and a regular maintenance habit costs far less than a restoration.
The best time to act is when paint first starts to crack or rust spots appear, before rust spreads under the surrounding coating. Spot repairs involve cleaning the rusted area back to sound metal, using lead safe methods on older paint, treating any remaining rust with a rust converter or inhibitor, priming with a zinc rich or rust inhibiting primer, and applying two coats of a durable enamel or metal paint. Products commonly used on ironwork in Australia include zinc primers such as Galmet, rust treatments and primers such as Wattyl Killrust, and direct to metal systems such as Dulux Metalshield. For heritage homes, specialist companies such as Porter's Paints offer period colour ranges, and many heritage fences look best in deep greens, dark browns, stone colours or black, depending on the era of the house. Keep garden beds, mulch and soil pulled back from the base of the fence so it can dry out. Trim plants that hold moisture against the ironwork. Wash coastal fences occasionally with fresh water to remove salt. Check gate hinges and latches each year and lubricate them, and inspect the bottoms of posts and the joints where water sits. A thorough inspection and touch up every year or two, and a full repaint every several years depending on exposure, keeps most fences sound for decades. Larger repainting jobs on long fence runs are quoted by fence painting businesses.
What Iron Gate and Fence Repairs Cost in NSW
Rust repairs on a panel typically cost $150 to $500, and replacing a rusted bottom rail section $200 to $600. Rehanging a gate with new hinges or pintles usually runs $200 to $600, while replacement finials and castings cost roughly $15 to $80 each to supply, plus fitting. General steel welding rates, useful for simpler mild steel repairs, are listed with other metals on the welding cost NSW page. Cast iron repairs using brazing, stitching or specialist welding run $250 to $1,200 depending on the piece. Full restoration, including removal, stripping, repair, galvanizing or painting and reinstallation, is usually priced at $400 to $1,200 per lineal metre. Getting two or three quotes on restoration work is sensible, because prices vary widely with each restorer's approach and workload.
Lead paint testing and removal, and stonemasonry on plinths and piers, are often priced separately. Ask for them as separate lines. New custom pedestrian gates cost $1,500 to $6,000 and driveway gates $3,000 to $10,000. Brick letterboxes and entry piers damaged along with the fence can be rebuilt by brick letterbox builders. Heritage work usually takes longer than modern fence repairs, so allow extra time in the schedule as well as the budget.
What to Look Out For
Make sure the tradesperson identifies the metal before starting, and be wary of anyone who wants to arc weld original cast iron without discussing the method, and insist on lead testing before any grinding, blasting or heating of old paint. Ask how posts will be reset in stone or brick so rust jacking does not recur. Check heritage controls before changing the design, and confirm whether the fence also serves as a pool fence. Get the coating system in writing. The ACCC explains the consumer guarantees that apply to repair work, and NCAT can hear home building and consumer disputes that cannot be resolved directly.
How to Get Useful Quotes
Photograph the whole fence and gate from the street, plus close ups of the damage, the base of the posts and any cast detail. Mention the age of the house and whether it is heritage listed or in a conservation area. Say whether the fence sits on sandstone or brick. Measure the length of fence involved and the width of each gate. Mention any missing pieces, and whether the gate is automated or opens onto a pool area.
Ask each tradesperson to state how they will identify the metal, manage lead paint, repair castings and finish the work, and whether stonework and painting are included. Older homes with iron security screens on doors and windows can have those assessed at the same time, and security doors and screens suppliers can advise on repair or replacement. Where a stonemason or bricklayer is also needed, ask whether the metalworker can coordinate them, so both trades are scheduled in the right order. Ask each tradesperson how long the fence will be removed or open, which matters for security, pets and any pool on the property.

Iron Gate and Fence Repair FAQs - NSW 2026
What do iron gate and fence repairs cost in NSW?
Rust repairs on a panel usually cost $150 to $500, gate rehangs $200 to $600 and cast iron repairs $250 to $1,200. Full restoration is often priced at $400 to $1,200 per lineal metre, and new custom gates start around $1,500.
Is my fence wrought iron?
Probably not, if it was built after the 1950s. Most scrolled wrought iron style fences are mild steel with arc welded joints. Original Victorian and Federation work is often cast iron, and some older bars are true wrought iron.
Can cast iron be welded?
With difficulty. Cast iron is brittle and tends to crack beside a weld. Specialists use preheating and special electrodes, brazing, or cold metal stitching, and sometimes recasting a new piece is the better option.
Does old paint on my fence contain lead?
Paint on ironwork from before about 1970 often does, including hidden layers under newer paint. Test before grinding, sanding, blasting or heating, and use lead safe removal methods if it is present.
Why is my sandstone plinth cracking around the fence?
Rust jacking. Iron bars set into the stone rust, and the rust expands and splits the stone. Repair needs both a metalworker and a stonemason, and the iron should be reset in a way that keeps water out.
Do I need council approval to repair a heritage fence?
Like for like repairs and maintenance are usually treated differently from changes. Replacing an original fence with a new design, changing its height or adding solid infill can need consent. Check your council's heritage controls first.
Can an old iron fence be part of a pool barrier?
Only if it complies with AS 1926.1, and decorative iron often has footholds and gaps that do not. Infill panels, new gate hardware or a compliant fence section may be needed. Have the barrier checked after any repair.
Why does my iron gate drag on the ground?
Usually worn hinges, dropped pintles, a leaning post or a twisted frame. The post needs to be sound first, then the gate can be rehung with new hinges and braced to stop sagging.
Who pays for a boundary iron fence repair?
Under the Dividing Fences Act 1991, neighbours generally share the cost of a sufficient dividing fence. Front fences facing the street are not dividing fences, so the owner usually pays.
How long does a restored iron fence last?
A properly restored fence with rust removed, repairs made, galvanizing where suitable and a good paint system can last decades with a touch up every year or two and repainting every several years.
