What should this cost here, and why do the quotes differ so much?
What perimeter drain work costs in Greater Victoria
Direct answer · reviewed 2026-09-22
The honest answer has two halves. The published local range for a new drainage installation is wide, and the published ranges for the same job in different parts of the province do not overlap at all, which tells you the figures are not measuring the same scope of work. And the price on your house is set by things nobody can see from the street: how deep the footing is, whether a machine can reach the trench, and what has to be rebuilt afterwards. Below is every figure we can attribute, who published it, and whether they sell the work.
Conditions and exceptions
- Every price on this page was published by a company that performs drainage work. We have found no independent survey for this market.
- A figure is a starting point for reading a quote, not a target to negotiate towards.
- Concrete, driveways, decks and mature landscaping are frequently the largest line on a drainage invoice, and they are not drainage.

The published figures, with their sources
Put the second and third rows beside each other and the problem is obvious: the ranges for what is described as the same job do not overlap. Either the work is genuinely much cheaper on the Island, or — far more likely — one figure covers a straightforward run on an accessible house and the other covers a full replacement with reinstatement. Neither company is lying; they are answering different questions with the same words.
| Work | Published figure | Who published it |
|---|---|---|
| Camera scope of the drain | From $295 | A Victoria drainage specialist |
| New drainage installation, Greater Victoria | $2,000–$10,000 | The same Victoria specialist |
| Full perimeter drain replacement, Vancouver and the Lower Mainland | $8,000–$15,000 and up | A Vancouver plumbing company |
| Time on site for a replacement | 1 to 4 weeks | A Victoria drainage specialist |
What actually moves the number on your house
Depth is first. A drain sits below the bottom of the floor slab by design, so a full basement means a deeper, wider, more heavily shored trench than a crawl space does, for the same length of pipe.
Access is second, and on Victoria's older lots it is often decisive. If an excavator can work around three sides, the job is machine work. If it cannot — a tight side yard, a neighbouring wall, a mature tree you are not allowed to remove — some of it becomes hand digging, and hand digging is the most expensive way to move soil there is.
Reinstatement is third and is the line homeowners are least prepared for. The trench comes out through whatever is on top of it. Grass grows back. A stamped concrete patio, a paver driveway or a sixty-year-old hedge do not, and putting them back is priced by other trades.
- Ask each quote to separate excavation, pipe and stone, discharge connection, and reinstatement. Four numbers, not one.
- Ask what happens if the trench finds something unexpected — rock, an unmarked line, a second old pipe — and how that is priced.
- Ask what is excluded. The exclusions are where two quotes that look similar stop being comparable.
Questions homeowners ask
- Why will nobody give me a price over the phone?
- Because the three things that decide it — depth, access and reinstatement — cannot be assessed over the phone, and a company that names a number anyway is either quoting the cheapest possible version or protecting itself with the highest. A site visit is reasonable to ask for. Paying for one usually is not.
- Is a cheaper quote a worse quote?
- Not by itself. It is a different quote, and the difference is almost always scope: less of the perimeter, no new discharge connection, or reinstatement left to you. The contractor questions page turns that into a list you can hold each quote against.
- Does home insurance pay for this?
- We have not verified how insurers in British Columbia treat perimeter drain work, so this site does not state a position. What we will say is that the exterior work itself and the interior damage are usually treated as different things, and that this is a question for your own policy wording and your broker, not for a drainage contractor.
