Best retaining wall builders in Bunbury (2026)
Table of Contents
These are the best-rated retaining wall builders working Bunbury, Australind and Eaton, from South Bunbury, Carey Park and Withers through Davenport, Glen Iris and Picton, out to Australind, Eaton, Dalyellup and College Grove. They’re ranked on real Google reviews, not on who paid us. As WA’s largest regional city, Bunbury has a genuinely healthy trade base, though only one of the eight names below is a dedicated retaining-wall-only business, the rest are a concreter, a general construction and landscaping firm, a bricklayer and several landscapers who build retaining as part of wider work. What follows is what a retaining wall actually costs in Bunbury in 2026, why drainage behind the wall matters more than the wall face itself, when you need council approval and an engineer’s design, the warning signs of a dodgy job, and a checklist to run before you pay a deposit.

- Google reviews do the ranking. We start with every builder’s live Google star rating and the number of reviews behind it, pulled fresh from Google Maps.
- Rating, weighted by volume. A perfect score off a handful of jobs isn’t proof yet, so we weight the score by review count. Bunbury Concreters’ 53-review record is why it leads a page full of smaller perfect-score operators.
- The genuine specialist is flagged. Only Bunbury Wall Retaining is a dedicated retaining-only business. Everyone else is a concreter, a general construction firm, a bricklayer or a landscaper who builds retaining as part of wider work, we’ve told you plainly what each one specialises in.
- Genuine local operators, not suppliers. We ran five separate Maps searches across this cluster. Several strong-looking names, including two sharing an identical materials-yard address, turned out to be landscaping supply yards rather than installers, and have been left off.
- Paid spots are labelled, and never jump the queue. When a business pays for a “Featured” spot it’s marked as such. The review-based order below does not change to favour a payer. Right now, no spots are sold.
Bunbury Concreters
A 4.9 across 53 reviews, easily the deepest and most consistent record on this page. As a concreter, retaining here typically means reinforced besser block or poured concrete, a strong option for taller, engineer-certified walls.
View listing & contact ▸Freedom Construction & Landscaping
A clean 5.0 across 22 reviews. A broader construction and landscaping outfit that handles retaining as part of a wider yard or property job, a solid option if your wall is one piece of a bigger makeover.
View listing & contact ▸Bunbury Wall Retaining
A 5.0 across 4 reviews, and the only name on this page that’s a dedicated retaining wall business rather than a generalist. A newer, smaller review base, but worth a call if you want a specialist rather than a generalist quoting your wall alongside other work.
View listing & contact ▸A note on the order: we weight the star rating by the number of reviews, so Bunbury Concreters’ huge, well-tested review base puts it clear at the top of a page full of smaller perfect-score names. Bunbury Wall Retaining is the only dedicated retaining specialist here, if you want a generalist who can quote a whole project including the wall, Freedom Construction & Landscaping or the landscapers further down are worth calling. As always, get two or three quotes on the same scope before you commit.
What a retaining wall actually costs in Bunbury (2026)
Nobody likes ringing a builder blind on price. These are honest WA ballpark ranges for the common retaining wall jobs, GST included. They’re a guide to keep you from being overcharged, not a quote, retaining wall prices move with height, material, ground conditions and access, so the spread on each line is wide for a reason. Bunbury is a healthy regional-city trade, not a thin market, established suburbs like South Bunbury, Withers and Carey Park often need an older, failing wall replaced, while the Australind, Eaton and Dalyellup growth corridor more often needs genuine cut-and-fill retaining on new-build blocks.
| Job | Typical WA range | What pushes it up |
|---|---|---|
| Limestone block wall, dry-stacked, under 600mm (per m²) | $260-$410 / m² | Height, access, whether backfill/drainage is included, site clean-up |
| Limestone block wall, mortared & engineered, over 600mm (per m²) | $410-$660 / m² | Height, engineering and permit costs, reinforcement, drainage complexity |
| Besser block, reinforced & rendered (per m²) | $360-$560 / m² | Reinforcement, render finish, height, engineering for taller walls |
| Excavation / cut-and-fill site works (per m³) | $30-$70 / m³ | Access, soil type, spoil removal, machine size |
| Engineer’s design & certification (required over 500mm) | $500-$1,500 | Wall height and length, soil report if required, site access, complexity |
| Council/building permit lodgement | $200-$600 | City of Bunbury or Shire of Harvey/Dardanup/Capel, wall height, boundary notice |
| Asbestos “Super Six” fence/wall removal (older Bunbury suburbs) | $40-$100 / m run | Licensed removal required, disposal fees, site access |
| Removal & disposal of an old failing wall (per m run) | $40-$90 / m | Wall material, height, access, tip fees |
South Bunbury and Carey Park are older, established suburbs where retaining is often a replacement job on a tired wall, and where some fence and boundary lines still carry asbestos “Super Six” fibro that needs licensed removal, budget for it separately if your job runs alongside older fencing or a boundary wall. Out through Australind, Eaton and Dalyellup, new-build blocks more often need genuine cut-and-fill retaining as part of the original site works. Either way, drainage behind the wall decides whether it lasts.
Don’t get ripped off: red flags
- No drainage behind the wall. This is the single most common cause of retaining wall failure in WA. A wall backfilled with plain excavated soil, with no agricultural drain and no free-draining material behind it, will trap water and eventually bulge, lean or collapse. Ask exactly what’s going in behind the wall.
- No engineer’s certification on a wall over 500mm. In WA, retaining walls above roughly 500mm generally need council or building approval and an engineer-certified design. A builder who shrugs this off is either wrong or hoping you won’t check.
- No plan for cut-and-fill site works. On new-build blocks around Australind, Eaton and Dalyellup, a retaining quote that doesn’t account for genuine earthworks and spoil removal will often blow out once digging starts.
- Not licensed for asbestos removal on older boundary work. If your job touches an older asbestos fence or wall in South Bunbury, Withers or Carey Park, confirm the crew is licensed for it, this is not a DIY-adjacent task.
- Cash-only, no ABN, no insurance. Retaining wall building is not a licensed trade in WA, but a genuine operator still carries an ABN and public liability insurance. No ABN, no insurance and a cash-only push is a red flag.
- The quote is well under everyone else’s. On retaining walls the lowball is almost always missing drainage, engineering or proper footings. Compare quotes on identical height, material, drainage provision and whether engineering is included.
- A big deposit up front. Materials for a retaining wall don’t justify a huge deposit before work starts. A modest deposit with the balance on completion is normal.
Before you hire: quick checklist
- ABN and public liability insurance. Confirm the builder has a current ABN and public liability cover before any work starts. Retaining wall building isn’t licensed in WA, so this is your main protection.
- Engineering for walls over 500mm. If your wall is taller than about 500mm, confirm an engineer will design and certify it, and that council approval is sorted before work starts.
- Drainage spelled out in writing. Get the backfill material, the agricultural drain and where the water actually goes written into the quote.
- Earthworks scope confirmed. On a new-build or cut-and-fill block, confirm whether excavation and spoil removal are included in the retaining quote or need a separate operator.
- Asbestos checked on older boundary work. If the job touches older fencing or walling, confirm whether asbestos is present and that removal is licensed.
- Written quote with the detail. Height, material, drainage, engineering (if required), and the price, all in writing before you pay a deposit.
- Recent, specific reviews and references. Look for recent reviews that mention an actual wall, and ask for a local job you can look at.
Frequently asked
How did you rank these retaining wall builders?
By their live Google star rating and the number of reviews behind it, pulled from Google Maps. We weight the rating by review volume so Bunbury Concreters’ proven, high-volume record leads a page full of smaller perfect scores.
Which areas does this cover?
Bunbury, Australind and Eaton. That runs across Bunbury, South Bunbury, Carey Park, Withers, Davenport, Glen Iris, Picton, Australind, Eaton, Dalyellup, College Grove and Usher.
Are these paid placements?
No. This list is ordered on Google review data. Businesses can pay for a “Featured” spot at the top, which is clearly labelled, but paying never changes the review-based order below. As of this update, no spots are sold.
Do I need council approval for a retaining wall in Bunbury?
Generally, yes, once the wall is above roughly 500mm high, and always where it involves a boundary or affects a neighbour’s land. Rules vary a little between the City of Bunbury and the surrounding shires, so confirm with your builder or your local council before work starts.
Do I need an engineer for my retaining wall?
For anything above roughly 500mm, yes, WA generally requires an engineer-certified design before council will approve it.
Why does drainage matter so much for a retaining wall?
Because water trapped behind a retaining wall creates hydrostatic pressure the wall isn’t designed to hold back. Without a compacted free-draining backfill and an agricultural drain to carry water away from the wall base, even a well-built wall face can bulge, lean or fail within a few wet winters.
How often is this page updated?
