What to know about Underpinning
Underpinning means extending a house's foundation downward so the footings bear on soil at a deeper level. In older Canadian neighbourhoods it's most often done to lower a basement: the floor is dug out, and the concrete footings under the walls are deepened one short section at a time so the house stays supported throughout. The same technique is used to repair a foundation that has settled, which our foundation repair page covers; this page is about lowering a basement by choice.

We list 11 other places within 30 km of Vancouver. Each pro sets their own service area, so tell us where the work is as well as what it needs.
Vancouver is the principal city of a wider area we list under the name Metro Vancouver, which takes in 14 other places. A pro's service area might be Vancouver on its own or the whole of it — we match on the one they gave us.
Vancouver publishes its own building-permit page, and it is linked below beside the rules that apply in British Columbia. Whether underpinning needs a permit is answered there, not in a quote.
Our British Columbia guide has no rule written for this trade, so there is none below. That is not the same as nothing applying: ask for proof of insurance, and for anything that touches gas, wiring or drains, ask who is certified to do it.
Underpinning costs in Vancouver
Prices depend on the details of your project. We only publish price ranges when they’re backed by real LokalMatch quote data or reliable sources. Until then, here’s what usually changes the price:
- Interior or exterior approach
- Length of foundation wall to excavate or treat
- Depth, soil conditions and access for equipment
- Crack repair, underpinning or other structural work
- Weeping tile, sump pumps and backwater valves
- Restoring landscaping, driveways or finished basements
- Testing and safe removal of mould or asbestos, where needed
How to choose underpinning contractors in Vancouver
- Choose a contractor who finds the source of the water before recommending a fix, whether that's grading, eavestroughs, cracks or drainage.
- Ask them to explain the difference between interior and exterior waterproofing for your home, and why they recommend one.
- For foundation cracks that are wide, growing or uneven, ask whether a structural engineer should assess them first.
- For mould, asbestos or radon, hire professionals qualified for that specific work, and don't disturb suspect materials yourself.
- Get a written quote that lists excavation, membranes, weeping tile, sump pumps and restoration of landscaping or finishes.
Questions to ask underpinning contractors before you hire
- Where do you think the water is coming from, and how did you confirm it?
- Do you recommend interior or exterior waterproofing for my home, and why?
- Should a structural engineer look at these cracks or this wall?
- Does this work need a permit from my municipality?
- Is your warranty transferable if I sell the house, and what does it cover?
- How will you restore the landscaping, driveway or basement finishes afterwards?
- If you find mould or asbestos, how will it be handled and by whom?
Underpinning permits in Vancouver
Some underpinning work needs a permit or has to meet local bylaws. Rules vary by municipality, so ask your pro whether a permit is needed and who will apply for it — and check with your city or town if you’re unsure.

Common underpinning questions
Is LokalMatch free for homeowners?
Yes. You never pay LokalMatch to request quotes or talk to pros. Professionals pay a fee to connect with homeowners whose projects fit their business.
How many pros will contact me?
We introduce you to a small number of relevant pros — usually no more than three — so you’re not flooded with calls. If fewer pros are available in your area, we’ll tell you instead of promising quotes we can’t deliver.
Do I have to hire someone?
No. Requesting quotes doesn’t commit you to anything. Compare your options and hire only if someone is the right fit.
