Crawlspace Encapsulation
in Lougheed, BC
The Lougheed area of Burnaby spans both sides of the Lougheed Highway as it passes through the municipality, with residential neighbourhoods extending north toward Burnaby Lake and south toward the Brentwood area. Burnaby Lake, while now a regional park, influences the hydrology of the surrounding area — the water table in some residential blocks near the lake is higher than would be expected based on topography alone, and seasonal fluctuations correspond with the lake level.
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 Lougheed — What We See Here
Homes in the Lougheed neighbourhood are primarily from the post-war era through the 1970s, with crawlspace foundations and the moisture management challenges that come with that vintage of construction. We work regularly in this area on encapsulation projects that address both the vapour diffusion from the soil and, in some cases near the lake, the higher water table through sump pump installation.
