Crawlspace Encapsulation
in Deer Lake, BC
The Deer Lake area of Burnaby encompasses some of the municipality's most established and valuable residential properties, surrounding the beautiful Deer Lake Park. Homes in this area tend to be on larger lots with mature landscaping, and many are of considerable heritage value as examples of mid-century residential architecture. The lake itself influences the local hydrology — groundwater levels in the immediate area around the lake are relatively close to grade.
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.
