Crawlspace Encapsulation
in Burquitlam, BC
Burquitlam sits at the boundary of Burnaby and Coquitlam, in the Como Lake area — one of the Lower Mainland's older suburban communities, with housing stock dating from the 1950s and 1960s. The neighbourhood has been experiencing rapid densification around the Burquitlam SkyTrain station, with high-rise development replacing some of the older single-family housing. What remains of the original residential stock has crawlspace foundations that are 50 to 70 years old and have had limited or no professional attention in many cases.
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 Burquitlam — What We See Here
Como Lake has an influence on local hydrology similar to Deer Lake in Burnaby — groundwater levels near the lake are elevated, and homes within a few blocks of the lakeshore may experience a higher water table than would be expected from their surface elevation alone. We account for this when sizing sump systems for affected properties.
