leaky basement repair & waterproofing in mission, abbotsford & coquitlam
Water coming through your basement walls, floor or cracks?
We find where it is getting in and fix it from the outside, where the problem starts.
A leaking basement is more than an inconvenience. Ongoing moisture damages flooring, drywall and belongings, encourages mould and can weaken your foundation over time. In the Fraser Valley, where heavy rain can last for months, a small leak rarely stays small.
Most basement leaks are caused by water building up in the soil outside your foundation. Interior sealants and coatings can hide the symptoms for a while, but the water pressure outside the wall remains. Our approach is to excavate, repair and waterproof the foundation from the outside, so water is stopped before it reaches your home.

what causes a leaky basement?
failed perimeter drains
When drain tile stops working, groundwater builds up against the foundation.
worn waterproofing
Older homes often have little or no protection on the outside of the foundation wall.
foundation cracks
Cracks and old form-tie holes give water a direct path inside.
poor grading
Soil that slopes toward the house directs rainwater straight to the foundation
downspout problems
Downspouts that discharge next to the house or into failed drains add water where you least want it.
Our assessment identifies which of these is affecting your home, so you pay for the repair that solves the problem.

LEAKY BASEMENT FAQ
-
During long periods of rain, the soil around your foundation becomes saturated. If drainage is failing or the wall is unprotected, the water pressure forces moisture through cracks and weak points. That is why many leaks appear in the fall and winter.
-
Interior products can reduce what you see, but they do not stop water from reaching the foundation. Exterior waterproofing keeps water away from the wall itself, which is why we recommend it for a long-term fix.
-
Not always. Failing drains are a common cause of basement leaks, so we check them as part of every assessment and only recommend replacement if they are part of the problem.
-
Yes. If the leak is limited to one area, we can often repair and waterproof only the affected section. We will explain your options after our assessment.
-
In most cases, no. Because we work from the outside, the finished space inside can usually stay in place.
-
Cost depends on how much of the foundation needs work, how deep it is, access around the home and the repairs needed. We provide a clear quote after assessing your property.
