My original timber wall is rotting. Repair or replace?

If the posts are rotted at ground level, replacement is usually the better spend. If only a few sleepers are affected and the posts are sound, repair can be an option. We check before recommending.

Do you also build the fence on top of the wall?

Yes. We regularly combine retaining walls with Colorbond fencing, with the posts and footings planned together.

How much does a retaining wall cost in Coombabah?

Cost depends on length, height, material, access, how much excavation is needed and whether engineering applies. We inspect the site and give you an itemised fixed price in writing rather than a rough rate per metre.

Can you work with limited side access?

Yes. We choose machinery to suit the access, and where a machine cannot get in, we plan for more hand excavation and price it upfront.

Can a retaining wall be built on the boundary?

Boundary walls are common, but they raise questions about the neighbour, fencing, drainage and in some cases approvals. We talk through these at the inspection before anything is planned.

Building retaining walls in Coombabah

If you are looking at a retaining wall in Coombabah, the first question is not which sleeper looks best. It is what the wall has to hold back and where the water will go.

Coombabah is a settled family suburb backing onto wetland reserve, with large blocks and plenty of room behind the house for a covered outdoor area.

The stock is mostly single-storey brick and tile homes from the 1980s and 1990s, often with a small original awning that no longer covers a usable table.

You get a fixed written price that covers excavation, materials, drainage, backfill and spoil removal, with any engineering listed separately.

Replacing older walls in established streets

In established suburbs many retaining walls are original treated pine walls that have reached the end of their life. Replacement with concrete sleepers or block is the most common job, often combined with new steps, paving or fencing while the ground is open.

Concrete sleeper walls in Coombabah

Concrete sleepers between galvanised steel posts are the most common wall we build. They will not rot, they suit most residential heights, and woodgrain or stone-look faces make them easy to match to the house. Post spacing and footing depth are set to the height and whatever sits above the wall.

Timber sleeper retaining walls

Treated pine and hardwood sleepers remain the most economical option for low garden walls. We use timber rated for ground contact, detail it to shed water, and are honest about its shorter lifespan compared with concrete.

Block and tiered garden walls

Segmental block walls suit curved lines and tiered gardens. They need a compacted base and drainage aggregate, and depending on the system and height, reinforcement back into the soil, so we plan the excavation footprint and access around that.

Replacing a leaning or rotted wall

When posts lean, sleepers bulge or soil washes through, repair rarely lasts. We remove the old wall in stages, support the soil, and rebuild with new posts, footings and drainage.
