Drain tile replacement cost in Vancouver

Quick answer

Lower Mainland contractors publish full-perimeter drain tile replacement ranges of roughly $12,000–$30,000 for a typical detached home, or about $80–$200 per linear foot all-in. Spot repairs are far cheaper. These are contractor-published references, not a guaranteed price for your house.

All amounts are Canadian dollars. Depth, hand digging in tight side yards, concrete and landscape restoration, and a new storm connection move the price most. This is educational information, not plumbing, engineering or legal advice; your municipality's current permit rules and a site inspection control your project.

What most people miss

Get the camera video before the excavator

A CCTV drain inspection (published locally at about $450–$850 with flushing) shows whether the perimeter drain is collapsed, root-filled or just silted up. Ask for the recording and a marked-up site plan. A full replacement quote without footage gives you nothing to compare.

How this price is built

Inspection and diagnosis

Camera inspection, flushing or hydro-jetting, and a written finding of where the drain has failed. Sectional repairs with new cleanouts are published locally around $2,500–$6,000.

Excavation and access

Linear feet of perimeter, dig depth to the footing, machine versus hand digging and soil disposal. Narrow Vancouver side yards often force hand digging, which raises the per-foot rate.

Drain system materials

Perforated pipe type, filter fabric or sock, clear drain rock, cleanouts and any connection to the storm sewer or sump. Ask whether foundation damp-proofing or a membrane is included while the wall is exposed.

Restoration

Walkways, pavers, decks, gardens and lawn. Restoration is published as adding about $2,000–$10,000+ and is where quotes differ most. Confirm whether the price includes finished restoration or rough backfill only.

Permits and inspection

Most Lower Mainland municipalities, including Vancouver, require a plumbing permit for perimeter drain replacement and storm connections. Confirm who pulls it, who books inspection, and that fees are in the quote.

What makes a quote high

No footage, full replacement
Replacing the whole perimeter without camera evidence may be necessary on an old clay-tile system, but you should see why.
Rough backfill sold as restoration
A lower quote may leave you to replace concrete and landscaping yourself. Compare finished-site scope.
Bundled waterproofing upsells
Interior systems, membranes and sump pumps can be legitimate, but each should be priced separately with a reason.
Missing permit
Unpermitted work can complicate a future sale or insurance claim. Ask for the permit number and final inspection.

Itemised versus vague

A quote you can evaluate looks different from one you can't. This is what to look for, line by line.

Item	A quote you can judge	A quote you can't
Diagnosis	Camera video, failure locations, marked plan	Drains are shot
Scope	Linear feet, depth, sides of house	Full drain tile job
Materials	Pipe, fabric, rock, cleanouts named	New weeping tile
Restoration	Each surface restored and priced	Backfill included
Permit	Contractor pulls permit and books inspection	Not usually needed

Questions to ask before you approve

Can I have the camera inspection video and a marked site plan?
How many linear feet and what depth are you pricing?
Is this machine or hand excavation on each side?
Exactly which surfaces will be restored, and to what finish?
Who pulls the plumbing permit and books the final inspection?

Message to a Vancouver drainage contractor

Copy these lines as they are. Politeness plus specifics gets answers.

1.“Please share the camera inspection video and failure locations.”
2.“List linear feet, depth and excavation method per side.”
3.“Name pipe, fabric, rock and cleanouts.”
4.“Itemize restoration of every surface and include the plumbing permit.”

When a high price is legitimate

A higher-than-expected price isn't automatically a bad one. These are the situations where it's usually justified.

Deep footings and hand digging in tight side yards take more labour.
Removing and replacing concrete, pavers or decks is real work.
A new storm connection or sump adds materials, permits and inspection.
Old clay or concrete tile often has to be replaced rather than repaired.

Common questions

How much does drain tile replacement cost in Vancouver?

Lower Mainland contractors publish about $12,000–$30,000 for a full perimeter on a typical detached home, or roughly $80–$200 per linear foot. Large homes with patios and tight access can exceed $35,000; spot repairs can be a few thousand dollars.

Do I need a permit for perimeter drain replacement?

Most Lower Mainland municipalities require a plumbing permit for perimeter drain replacement and storm connections. Check with your municipality for your address.

Can my drain tile be repaired instead of replaced?

Sometimes. A camera inspection shows whether the problem is a local collapse or blockage, which can be repaired, or a failed system.

Does home insurance cover drain tile replacement?

Usually not for wear and age, but policies differ. Ask your insurer in writing before assuming coverage.
