Crawlspace Encapsulation
in Pitt Meadows, BC
Pitt Meadows occupies the flat delta land between the Pitt River and the Golden Ears foothills — historically some of the most productive agricultural land in BC, and now increasingly a mix of residential neighbourhoods, industrial areas, and protected agricultural reserve. The residential community is relatively compact, centered around the Downtown Pitt Meadows core and the residential streets extending south and west. The low-lying position of the entire municipality means water table management is a consistent concern in any crawlspace context.
Crawlspace encapsulation is one of the most effective investments a homeowner in Surrey or the broader Lower Mainland can make. The process involves covering the crawlspace floor and walls with a continuous, heavy-duty polyethylene vapor barrier — typically 12-mil or 20-mil reinforced poly — then sealing every seam, penetration, and vent opening with industrial-grade tape and adhesive. The result is a fully conditioned environment that is physically isolated from ground moisture and the damp Pacific Northwest soil beneath your home.
The installation process begins with a thorough cleanup — removing old fiberglass batt insulation (which absorbs moisture and harbors mold), clearing any debris, and treating visible mold colonies. Technicians then install the vapor barrier across the ground, lapping it up the walls and piers, and sealing it to the stem wall with adhesive and mechanical fasteners. All vents are closed and sealed from the inside. Depending on the space, we may also install a commercial-grade dehumidifier calibrated to maintain relative humidity around 50 to 55 percent throughout the year.

About Pitt Meadows — What We See Here
Homes in Pitt Meadows built on the flat bottomland sit in an area where the water table is very close to grade for much of the year — similar to parts of Richmond and South Delta. Sump pump systems are not optional in these conditions; they are a fundamental requirement for keeping crawlspaces dry. The flat topography also means that exterior grading improvements have limited effectiveness — there is simply not enough slope to move water away from foundations by gravity alone, which makes interior drainage and pumping more important here than in hillside communities.
The proximity to the Fraser River and Golden Ears Provincial Park means Pitt Meadows receives significant precipitation funnelled by the valley, and the community's storm drainage system must handle large volumes of water during major weather events. We design crawlspace drainage systems for Pitt Meadows properties to handle the full wet-season load, not just average conditions — sizing sump pumps conservatively and including battery backup as standard practice.
