How Much Does a Retaining Wall Cost in Burnaby BC? (2025 Guide)

The most common question we get from Burnaby homeowners is simple: "What's it going to cost?" It's a fair question and it deserves a direct answer — not a list of every factor that might affect the price followed by "it depends."

So here's the honest answer: a typical residential retaining wall in Burnaby runs $250–$900 per linear metre of installed wall, depending on material, height, drainage requirements, site access, and permit costs. A 15-metre wall at 1.0m height might cost $5,000 to $12,000. The same wall at 1.8m height with engineering might run $15,000 to $25,000.

Those ranges are wide for a reason — retaining wall cost is genuinely variable. But this guide breaks down the cost components so you can understand where the money goes and what to expect for your specific situation.

Material Costs by Wall Type

Material type is the biggest driver of cost variation between wall types. Here's where each common material sits in Burnaby's market in 2025:

Timber/railway tie walls: $200–$350 per linear metre installed, for walls under 1.0m high. This is the most affordable option. Keep in mind the 15–25 year service life — over that period, a timber wall often costs more than a block wall when you factor in eventual replacement.

Concrete block (CMU) walls: $350–$600 per linear metre for walls under 1.5m. Reinforced concrete block is more expensive than interlocking block for short walls but becomes economically competitive at heights over 1.5m.

Interlocking block walls (Allan Block, Versa-Lok): $350–$600 per linear metre for walls under 1.2m. Add geogrid reinforcement and this increases to $500–$750 per linear metre for walls up to 2m.

Natural stone walls: $500–$900 per linear metre for dry-stack or mortared stone up to 1.2m. Stone is the most labour-intensive material — wall building with irregular stone can't be rushed.

Poured concrete cantilever walls: $700–$1,200+ per linear metre. These are for structural applications and include the additional cost of formwork, reinforcing steel, and concrete placement.

Gabion walls: $400–$700 per linear metre depending on basket size and rock type. Rock supply and delivery is a significant cost component.

What's Included (And Not Included) in a Wall Quote

When comparing quotes from retaining wall contractors in Burnaby, make sure you're comparing apples to apples. A cheap quote might not include drainage, permit fees, or site cleanup. A more thorough quote includes all of these.

A complete quote should include: excavation and spoil removal, compacted granular base preparation, drainage aggregate and perforated pipe, the wall itself (all materials and labour), backfill and compaction, site cleanup and final grading, and permit application fees where applicable.

Items that are sometimes excluded from quotes and should be clarified: hauling away excess excavated material (this can add $500–$2,500 depending on volume), engineering fees (typically $1,500–$5,000 for residential walls requiring stamped drawings), permit application fees (typically $200–$800 in Burnaby depending on project scope), and any tree or vegetation removal in the work area.

Ask specifically about each of these when you're getting quotes. The lowest quote is often not the complete quote.

How Height Affects Cost

Wall height affects cost in two ways: it directly increases the volume of material (more block, more drainage aggregate, more excavation), and it can trigger permit requirements and engineering costs.

For a rough sense of how height scaling works: going from a 1.0m wall to a 1.5m wall of the same material is roughly 1.5x the material cost but closer to 2x the total project cost, because excavation, drainage, and labour costs don't scale linearly with height. A taller wall requires deeper excavation, more drainage pipe, and more careful placement and compaction.

For walls over 1.2m — the Burnaby permit threshold — add $200–$800 for permit fees and potentially $1,500–$5,000 for engineering, depending on wall type and height.

Drainage Cost

Drainage is not optional, but it is sometimes omitted from cut-rate quotes to make the initial price look lower. A proper drainage system — clear crush aggregate, 100mm perforated pipe, geotextile filter fabric, and a proper outlet — adds $50–$120 per linear metre to a retaining wall project.

That sounds like a lot until you consider that inadequate drainage is the number one cause of retaining wall failure in BC. A wall without drainage in Burnaby's climate that costs $3,000 less up front and fails in 8 years instead of 30 years was not a deal.

We include drainage specification and installation in every retaining wall quote we provide. We won't build a wall without it.

Getting an Accurate Quote

The only way to get an accurate retaining wall cost for your specific project in Burnaby is to have a contractor come out and look at the site. The variables — soil conditions, site access, drainage outlet options, proximity to property lines and structures, existing vegetation — can't be assessed from a description or photos.

We offer free on-site assessments and written quotes across Burnaby and the Lower Mainland. Our quotes include a complete specification of materials, drainage, and any permit requirements — so you know exactly what you're getting and can compare accurately with any other quotes you receive.
