Understanding Garden Edging Installation Costs in Western Australia
Garden edging is one of the most impactful finishing elements in any landscape, transforming a garden from a loosely defined outdoor space into a polished, well-organised environment with clean lines and clear boundaries between different zones. Quality edging separates lawn from garden beds, contains mulch and soil within planting areas, prevents grass from creeping into beds and paths, and creates defined borders that make lawn mowing and garden maintenance significantly easier. The visual impact of well-installed edging is disproportionate to its cost, making it one of the highest-value investments in a landscaping project on a per-dollar basis. Whether you are edging a new landscape as part of a comprehensive project or adding edging to an existing garden to sharpen its presentation, understanding the material options, installation methods and costs helps you make informed decisions that deliver the right result for your property.
The cost of garden edging in Western Australia depends primarily on the material selected, with prices ranging from as little as $10 per linear metre for basic plastic or composite edging through to $120 or more per metre for premium natural stone edging with a concrete footing. The total length of edging required is the other major cost driver, and a typical Perth residential property with garden beds along two boundaries, a lawn border and a few tree surrounds might require 40 to 80 linear metres of edging in total. For a mid-range material such as steel or concrete kerbing, that translates to a project cost of $1,200 to $4,000 fully installed. The installation labour component is significant because edging requires careful preparation of the trench or channel, precise levelling, and secure fixing to ensure the edging remains stable and level over many years of use.
Perth's sandy soil conditions affect both the installation method and the long-term performance of garden edging. Sandy soils shift more readily than clay soils, and edging installed without adequate anchorage in Perth sand can move, tilt or settle unevenly over time as foot traffic, irrigation water and soil movement take their toll. Professional installation compensates for the sandy conditions by providing appropriate anchorage for each material type, whether that means driving steel edging to sufficient depth with secure stake pins, pouring concrete kerbing onto a compacted base, or bedding stone or brick edging on a mortar or concrete footing that prevents lateral movement. The investment in professional installation pays for itself over the life of the edging by preventing the gradual deterioration and misalignment that are common with DIY installations in Perth's challenging soil conditions.
Steel and Metal Edging
Steel edging has become the most popular choice for residential garden edging in Perth and across Western Australia over the past decade, driven by its clean, contemporary appearance, flexibility in curved applications, and relatively straightforward installation process. Raw steel edging, often marketed as Corten or weathering steel, develops an attractive rust-brown patina over time that complements both modern and traditional garden designs and blends naturally with mulched garden beds and natural stone elements. The cost of steel edging in WA ranges from $20 to $40 per linear metre fully installed, with the variation reflecting the steel thickness, height and whether the product is a flat strip or a formed profile with a folded top edge for added rigidity and a smoother finish.
Steel edging is available in several height profiles to suit different applications. A 150mm exposed height is suitable for separating lawn from garden beds where the primary purpose is to contain mulch and prevent grass encroachment, while a 200mm or taller profile is appropriate for applications where the edging also needs to retain a modest level difference between two adjacent surfaces. Steel edging strips are typically supplied in lengths of 1 to 2.4 metres and are joined on site using an overlapping connection that slides together without visible fixings. The flexibility of steel strip edging allows it to follow gentle curves without kinking, making it ideal for the organic, flowing garden bed shapes that are popular in contemporary Australian landscape design. Tighter curves require shorter sections or pre-formed curve pieces to achieve a smooth line without unsightly kinks or flat spots.
Aluminium edging offers a similar aesthetic to steel but without the rusting patina, making it the preferred choice when a permanent silver, black or powder-coated colour finish is desired. Aluminium edging costs $25 to $50 per linear metre installed, slightly more than steel due to the higher material cost and the powder-coating process that provides the finished colour. Aluminium does not rust and requires no ongoing maintenance, making it a good choice for coastal properties where salt air can accelerate the deterioration of steel products. Both steel and aluminium edging require installation with steel pins or stakes driven into the ground at regular intervals, typically every 600 to 900mm, to hold the edging firmly in position. In Perth's sandy soils, longer stakes of 250 to 350mm provide better anchorage than the shorter stakes that may be adequate in heavier clay soils in other parts of Australia.
Concrete Kerbing
Continuous poured concrete kerbing, commonly known by the franchise brand name Kwik Kerb, is a popular edging choice in WA that provides a solid, permanent border with a smooth, uniform appearance. Concrete kerbing is extruded on site from a specially formulated concrete mix using a machine that shapes the kerb as it moves along the prepared trench line, producing a continuous length of kerbing without joins. The cost of concrete kerbing in WA ranges from $40 to $65 per linear metre installed, with the variation depending on the kerb profile selected, the total length, the number of curves and corners, and whether decorative colour or stamp finishes are applied. A straight run of standard bullnose kerbing at the lower end of the price range is an efficient way to edge long garden bed borders, while complex layouts with multiple curves, corners and custom profiles push costs toward the higher end.
The advantages of concrete kerbing include its seamless appearance, the wide range of colour and texture options available, and its durability once properly installed and cured. Concrete kerbing can be coloured using integral colour mixed into the concrete before extrusion, or surface colour applied to the finished kerb, with a range of earth tones, charcoal, sandstone and terracotta shades available to match different garden styles and hard surface colours. Stamped finishes that replicate the appearance of brick, cobblestone or slate are also available at a premium, adding a decorative element that enhances the visual appeal of the edging. The solid mass of concrete kerbing provides effective containment of mulch, soil and gravel, and its smooth top surface creates a convenient mow strip that allows the mower to run along the edge of the lawn without the need for separate line-trimming along the garden bed border.
Concrete kerbing does have limitations that are worth understanding before committing to this material. Cracking is the most common issue with concrete kerbing, and it is particularly relevant in Perth's sandy soils where ground movement from seasonal moisture changes, tree root growth and foot traffic can cause the kerbing to fracture over time. Reinforcement with fibre or mesh within the concrete mix reduces the risk, and a compacted base beneath the kerbing provides a more stable foundation that resists differential settlement. However, some cracking over the life of the kerbing is normal and should be expected, particularly on longer runs and in areas adjacent to large trees. Repair of cracked kerbing is possible but rarely seamless, as colour matching and blending new concrete into the existing kerbing is difficult. Trees in the immediate vicinity can also cause lifting and displacement of concrete kerbing as roots grow beneath it, and discussing the proximity of trees with your installer helps identify areas where alternative edging materials might perform better in the long term.
Brick and Paver Edging
Brick and paver edging provides a traditional, structured look that suits a wide range of garden styles and complements the brick and paver materials commonly used in WA driveways, pathways and entertaining areas. Brick edging is installed by laying bricks in a prepared trench, either vertically on end for a saw-tooth effect, flat in a single or double row for a mow strip, or at an angle for a decorative pattern. The cost ranges from $45 to $90 per linear metre installed depending on the brick type, the laying pattern and whether the bricks are bedded on sand or mortar. Using the same brick as the house or matching the colour of existing paving creates a cohesive visual connection between the built elements and the garden, which is an effective design technique for tying a landscape together.
Paver edging uses the same types of concrete or clay pavers that are used for driveways and pathways, laid in a single or double row to form a border between different landscape zones. Midland Brick and Austral Bricks manufacture a range of pavers in colours and finishes that suit WA conditions and complement the colour palette commonly found in Perth residential exteriors. Paver edging bedded on a compacted sand base is a cost-effective and durable solution for garden bed borders, and the pavers can be laid flush with the lawn surface to create a mow strip that allows the mower wheel to run along the edge for a clean finish without manual trimming. A mortar bed provides a more permanent installation that prevents individual pavers from shifting or being displaced by foot traffic or garden activity, though it increases the installation cost and makes future adjustments more difficult.
The durability of brick and paver edging in Perth's conditions is generally excellent, as both clay bricks and concrete pavers are resistant to the UV exposure, temperature fluctuations and moisture cycles that characterise the WA climate. The main maintenance requirement is periodic re-levelling of pavers that settle or shift due to soil movement or root growth, and occasional replacement of individual units that crack or chip. Keeping the joints between bricks or pavers clear of soil and weed growth maintains the neat appearance and prevents the gradual displacement that occurs when roots and organic matter accumulate in the gaps. A polymeric sand jointing product swept into the joints after installation inhibits weed growth and binds the pavers together, providing a low-maintenance finish that stays clean longer than standard bedding sand.
Natural Stone Edging
Natural stone edging creates a premium, organic look that suits both contemporary and rustic garden designs, and the range of stone types available in WA provides options for virtually any aesthetic preference and budget. Limestone is the most traditional and widely used edging stone in Western Australia, reflecting the local geology and the long history of limestone use in WA construction and landscaping. Rough-cut limestone blocks laid as edging provide a natural, textured finish that complements native plantings and Mediterranean-style gardens, while saw-cut limestone offers a more refined appearance with uniform dimensions and a smoother surface. Limestone edging costs between $50 and $90 per linear metre installed depending on the block size, the cut finish and the installation method.
Other natural stone options popular in WA include granite, sandstone, bluestone and quartzite, each with distinct colour, texture and durability characteristics. Granite is the hardest and most durable natural stone option, available in a range of greys, blacks and earth tones, and costs $70 to $120 per linear metre installed for edging applications. Donnybrook sandstone, quarried in the South West of WA, is a warm-toned local stone that provides a distinctive regional character and is particularly popular in the South West and Perth hills areas. Natural stone edging is typically installed by bedding each stone on a mortar or concrete footing to prevent movement, with the stones butted together or spaced slightly apart depending on the desired aesthetic. The irregular natural faces of rough-cut stone create visual interest and a sense of permanence that manufactured edging products cannot replicate.
The weight and bulk of natural stone make it one of the most effective edging materials for retaining soil and containing garden beds, particularly on gently sloping sections where a modest level change needs to be managed. Stone edging up to approximately 300mm in height can be installed without engineering, effectively functioning as a miniature retaining wall that holds back soil and mulch while creating an attractive garden border. For situations where the level change exceeds 300mm, a proper retaining wall designed and constructed to structural standards is the more appropriate solution. Your landscaper or edging installer can advise on the most suitable approach based on the specific conditions of your site, including the level difference, soil type, drainage requirements and proximity to structures or boundaries.
Plastic and Composite Edging
Plastic and composite edging materials occupy the budget end of the garden edging market, offering a functional border at the lowest cost per metre. Plastic roll edging, available from hardware stores including Bunnings and Mitre 10, costs $5 to $12 per metre for the material and can be installed by a gardener or landscaper at a total cost of $10 to $20 per metre including labour. The main advantage of plastic edging is its low cost and ease of installation, making it a practical choice for properties where budget is the primary concern or where the edging is a temporary solution while a more permanent material is planned. Composite edging products, typically made from recycled plastic and wood fibre, offer improved aesthetics and durability over basic plastic at a slightly higher price point of $15 to $25 per linear metre installed.
The limitations of plastic edging should be considered before selecting this material. Plastic edging degrades under prolonged UV exposure, becoming brittle and cracking after several years of exposure to Perth's intense sunlight. It lacks the rigidity of steel or concrete, meaning it can be displaced by soil pressure, root growth or accidental contact with garden equipment. The appearance of plastic edging is generally considered inferior to metal, concrete or natural stone alternatives, and it can detract from the overall quality of a well-designed landscape. For budget-conscious projects, steel edging at the lower end of its price range often represents better value than plastic when the longevity and appearance are factored in, as a steel edge installed at $20 per metre lasts fifteen years or more while plastic edging at $12 per metre may need replacement within five to seven years.
Choosing the Right Edging for Your Garden
Selecting the right edging material involves balancing aesthetic preferences, functional requirements, budget constraints and the long-term maintenance commitment you are willing to make. The style of your home and garden should guide the material choice, as the edging should complement rather than clash with the existing hard surfaces, building materials and planting style. A modern, minimalist garden with clean lines and a limited colour palette suits steel or aluminium edging with its precise, linear aesthetic, while a cottage-style garden with flowing garden beds and mixed plantings may look better with the softer, more organic appearance of natural stone or aged brick. Consider the colour and finish of existing paving, the house exterior, fencing, and decking when selecting the edging material and colour to ensure a cohesive result across the whole landscape.
Functional requirements should also inform your material selection. If creating a mow strip that allows the lawn mower to run along the edge without manual trimming is a priority, a flat-topped edging material such as concrete kerbing or brick pavers laid flush with the lawn surface is the most practical choice. If containing mulch in garden beds on a sloping site is the primary function, a taller edging profile such as 200mm steel or stacked stone provides the necessary height to hold the mulch in place. Properties with significant tree plantings should consider the interaction between tree roots and the edging material, as concrete kerbing and rigid stone edging can be displaced by root growth while steel edging is more flexible and accommodating of gradual ground movement. Discussing these functional priorities with your landscaper ensures the edging selection addresses the practical needs of your garden as well as the visual preferences.
The total length of edging required significantly affects the total project cost, and measuring or estimating the linear metres of edging before requesting quotes gives you a realistic basis for budgeting. Walk around your property and identify every location where edging would be beneficial, including garden bed borders, lawn edges, pathway borders, driveway edges and tree surrounds, and measure or estimate the total length. A typical Perth residential property with standard garden beds and lawn areas requires 40 to 80 linear metres of edging, though properties with extensive garden beds, multiple trees and complex layouts may need 100 metres or more. Multiplying the total length by the per-metre cost of your preferred material gives you an approximate project cost, though your installer's quote will account for site-specific factors such as ground conditions, curves, corners and access that may adjust the price up or down from the estimated figure.
Installation Process and Preparation
Professional garden edging installation follows a systematic process that begins with marking out the edging lines, preparing the ground, installing the edging, and finishing with backfilling and levelling. The first step is to mark the intended edging lines using string, paint or a garden hose to establish the layout and confirm that the lines flow naturally and create the desired shapes. Any existing edging that is being replaced must be removed, along with any grass, roots or debris in the edging channel. The installer then excavates a trench or channel of appropriate depth and width for the selected material, compacts the base if a footing is required, and installs the edging according to the manufacturer's specifications and industry best practice.
Ground conditions in Perth affect the preparation requirements and the installation cost. In the sandy soils that predominate across the metropolitan area and coastal regions, the trench sides may not hold their shape during excavation, requiring slightly wider trenches and more careful installation to achieve precise alignment. Rocky or clay-based soils found in parts of the Perth hills and some inland areas require more physical effort to excavate but provide a more stable base for the edging once installed. Tree roots in the edging path present a common challenge that must be assessed and managed during installation. Cutting through significant roots to install edging can damage the tree's health and stability, and an experienced installer will adjust the edging line to avoid major roots where possible or consult an arborist for advice on which roots can be safely pruned and which must be preserved.
The finishing stage of an edging installation is critical to the final appearance and involves careful backfilling against both sides of the edging to the correct level, compacting the backfill to prevent subsequent settling, and adjusting the lawn or garden bed levels to meet the edging neatly. Lawn areas adjacent to new edging may need to be trimmed back to create a clean gap between the grass and the edging, and garden bed areas should be topped with fresh mulch to a level that sits just below the top of the edging. Proper finishing distinguishes a professional installation from an amateur one and ensures the edging looks sharp and performs well from day one. Your installer should also clean up all excavated soil, removed old edging material and installation debris as part of the project, leaving your garden tidy and ready to enjoy.
Compliance and Practical Considerations
Garden edging installation is generally classified as minor landscaping work that does not require a building permit or specific trade licence in Western Australia. However, edging that forms part of a larger landscaping project valued at $20,000 or more falls under the structural landscaping threshold that requires a registered builder, as regulated by the Department of Mines, Industry Regulation and Safety. If your edging project is a standalone job or part of a smaller project, a qualified landscaper without a builder's registration can legally perform the work. Regardless of the project size, the installer should carry public liability insurance and comply with the workplace safety obligations set out by WorkSafe Western Australia, which include safe manual handling practices and appropriate use of powered tools.
Before digging the edging trench, it is essential to confirm the location of any underground services that pass through or near the edging line. Water pipes, gas lines, electrical cables, telecommunications conduits and irrigation reticulation pipes are all commonly found at shallow depths in Perth residential gardens, and striking any of these during excavation can be dangerous, costly and disruptive. The Dial Before You Dig service provides free plans showing the approximate location of underground services, and your installer should request these plans and use hand digging or non-destructive methods in areas where services are indicated. Reticulation pipes are not registered with Dial Before You Dig as they are installed by private contractors, so locating your irrigation lines before the edging installation avoids the inconvenience and cost of repairing a damaged pipe.
Drainage is a practical consideration that should not be overlooked when planning edging layouts. Edging can act as a barrier to surface water flow, and in Perth's sandy soils where drainage is generally excellent, this is rarely a problem on flat ground. However, on sloping sites or in areas where water drains across the surface toward the house, garden beds or paved areas, the edging layout must allow water to pass through or around the edging rather than being trapped against a surface where it can cause erosion, waterlogging or moisture damage. Solutions include leaving small gaps at strategic points in the edging run, installing edging with drainage slots, or incorporating garden lighting bollards or features at drainage break points to maintain visual continuity while allowing water movement. The Western Australian Government provides guidance on stormwater management for residential properties that applies when edging or other landscape elements alter the existing surface drainage patterns on a property.
What to Look for in Garden Edging Quotes
When requesting quotes for garden edging installation, provide each installer with the same information so the quotes are directly comparable. This information should include the total approximate length of edging required, the material you are interested in or are open to, the locations where edging will be installed, whether old edging needs to be removed, and any specific design features such as curves, corners or tree surrounds. Inviting the installer to visit the property before quoting allows them to assess the ground conditions, identify any underground services, note any access constraints for equipment and materials, and provide a more accurate price based on the actual site conditions rather than assumptions.
A detailed quote should specify the edging material including the brand, product name, height and finish, the method of installation including the type of base preparation and fixing, the total linear metres included, the per-metre rate and the total cost. Check whether the quote includes removal and disposal of old edging if applicable, whether it includes backfilling and finishing to both sides of the edging, and whether green waste or soil removal is included or additional. Some installers quote a per-metre rate that covers everything, while others break out the base preparation, material supply and installation labour as separate line items. Both approaches are legitimate, but ensure you are comparing total costs rather than just the per-metre material rate when evaluating competing quotes.
Ask each installer about their experience with the specific edging material you have selected and request examples or photos of previous installations. A specialist kerbing contractor who installs concrete kerbing daily will produce a higher-quality result than a general gardener who does kerbing occasionally, and the same principle applies to steel edging, stone edging and brick edging. Verify that the installer carries current public liability insurance and can provide a valid ABN for invoicing. The Department of Commerce provides guidance on consumer rights when engaging contractors for home improvement work, and the Australian Competition and Consumer Commission publishes information on consumer guarantees that apply to services purchased by Australian consumers, including the guarantee that services will be provided with due care and skill.
Regional Considerations Across Western Australia
Perth metropolitan homeowners have access to the widest range of edging materials and the largest pool of experienced installers, resulting in competitive pricing and short lead times for most edging projects. Specialist concrete kerbing franchises and independent operators service the entire Perth metro area, and steel, aluminium, stone and brick edging installers are readily available across the suburbs. Material supply is straightforward, with landscape supply yards, hardware stores and specialist edging suppliers all accessible within the metropolitan area. The sandy soils that characterise most of the Perth coastal plain require the installation techniques described in this guide, while properties in the Perth hills, Darling Scarp foothills and parts of the eastern suburbs encounter rockier ground conditions that may increase the excavation time and cost.
The South West region from Mandurah through Bunbury, Busselton and Margaret River has a growing number of edging installers, though the range of specialist operators is narrower than in Perth. Concrete kerbing services and general landscapers who install steel and brick edging are available throughout the South West, and the region's proximity to the Donnybrook sandstone quarries provides cost-effective access to this attractive local stone for properties seeking a natural stone edging option. The South West's heavier soils compared to Perth's sand provide a more stable base for edging installation, which can reduce the preparation requirements and potentially lower the installation cost per metre. Regional properties with larger blocks and more extensive garden areas may require longer total runs of edging, which provides economies of scale that reduce the per-metre cost as the fixed mobilisation and setup costs are spread across more metres of installed edging.
Regional and remote WA properties face higher edging costs due to material transport and limited installer availability. In regional centres such as Geraldton, Kalgoorlie, Karratha and Broome, the range of available edging materials may be limited to what local suppliers stock, and specialist materials may need to be transported from Perth at additional cost. Local landscapers in these areas can install most edging types, and combining the edging work with other landscaping projects reduces the per-project mobilisation cost. Properties in cyclone-prone regions of the Pilbara and Kimberley should consider the impact of intense rainfall events on edging, as the heavy rains associated with cyclones can cause erosion and soil movement that displaces edging not adequately anchored. Steel edging driven to a greater depth and stone edging on concrete footings provide the best resilience in these conditions. Fencing, pergola construction, patio installation, shade sail fitting and outdoor kitchen projects in regional areas similarly benefit from forward planning and the coordination of multiple trades into a single mobilisation to keep costs manageable.
