What to know about Basement waterproofing
Basement waterproofing is the work of keeping water and dampness out of the lowest level of a house, whether it shows up as a puddle after the spring thaw, a damp band along the bottom of a wall or a musty smell that never quite leaves. Below grade, foundation walls and floor slabs sit against soil that stays wet for much of the year, and concrete and concrete block are porous enough to let moisture through when nothing stops it. A good waterproofing contractor looks at the whole picture: the ground around the house, the foundation itself, the drainage at the base of the footing and the air inside the basement.

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 waterproofing contractors in Westmount
- 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 waterproofing 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?
