Crawlspace Encapsulation
in Austin Heights, BC
Austin Heights is one of Coquitlam's established mid-slope residential neighbourhoods, with housing from the 1960s through the 1980s on terrain that provides reasonable natural drainage. The community sits above the Burquitlam lowlands on a terrace that avoids the worst of the water table challenges in the lower areas, while benefiting from the gentle slope toward natural drainage outlets.
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 Austin Heights — What We See Here
The housing stock in Austin Heights has the typical characteristics of its era: vented crawlspaces with original fibreglass insulation that has long since failed, vapor barriers that were minimal where they existed at all, and framing that shows various degrees of moisture exposure depending on how well each individual property's drainage has performed over the decades. We provide standard encapsulation and moisture management services throughout Austin Heights, tailoring the scope to the specific condition of each property we inspect.
