Moisture damage that creeps up on you

Those stains signal a problem. Left unaddressed, trapped moisture damages wood framing, cladding, and trim, turning a manageable fix into a costlier repair.

Waterproofing isn’t only about storm damage. Older homes in this area often have aging caulking, worn sealants around windows and doors, or exposed deck surfaces that allow moisture in season after season, compromising your home’s exterior.

Prevent water damage

Dark stains on your foundation show that water is getting in. Our exterior waterproofing stops this by sealing the outside of your foundation. This creates a permanent barrier that directs rain and soil moisture away from your walls.

The process starts with digging down to the footing. Then, we apply a bonded membrane and a dimpled drainage board. This setup relieves pressure from water and safely channels it to the weeping tile. For homeowners in Vancouver, waterproofing in Vancouver means using a system that can handle months of steady rain without failing.

Important for Vancouver's climate

Vancouver’s winters bring weeks of drizzle, keeping the ground saturated. When the clay-heavy soils around the Fraser delta swell, they hold moisture against basement walls. Even small flaws in the foundation can lead to leaks.

Older homes in Kitsilano and post-war bungalows in East Van often have a common issue: original damp-proofing that doesn’t last. When downspouts discharge too close to the footing, it leads to dark stains on many homes. Our crews work throughout Vancouver and understand how local soils drain—or don’t.

Waterproofing Techniques

Paragon Exteriors uses strong waterproofing materials that fit the climate and soil of Vancouver. Our teams apply a liquid membrane that creates a solid barrier against water. We also use a heavy-duty dimpled drainage board to reduce pressure from water and direct moisture away from the foundation.

For homes in Vancouver’s wet climate, we suggest a polyurethane waterproofing system. This flexible, self-sealing formula can handle the freeze-thaw cycles without cracking or peeling. We use stainless steel fasteners that resist corrosion to secure the system, preventing damage from strong winds.

Structural Waterproofing

Good waterproofing in Vancouver needs a careful design for the building’s outer layer. Our teams create a system that controls moisture from below the foundation to the walls above. This starts with proper drainage to move groundwater away from the footing and includes a vapor-permeable air barrier that stops liquid water but lets walls breathe.

For homes in Vancouver’s damp climate, we choose insulation with high R-values to keep heat steady and avoid condensation. We place flashing and sealants at all openings to ensure water flows to the outside. This careful design protects against the area’s heavy rain and coastal winds.
