Crawlspace Encapsulation
in Cedar Hills, BC
Cedar Hills is one of Surrey's established inner-suburban neighbourhoods, with a housing stock predominantly from the 1960s through the 1980s. The area sits on relatively flat terrain in the central part of the municipality, with clay-loam soils that drain slowly after rain events. The neighbourhood's age means that many crawlspaces here have never been professionally assessed or treated, and we frequently find significant moisture damage and mold accumulation when we inspect homes in this area.
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 Cedar Hills — What We See Here
The combination of age and soil conditions in Cedar Hills makes it a neighbourhood where we often recommend comprehensive remediation rather than partial fixes. Homes here typically need old insulation removed, mold treated on the subfloor framing, a new encapsulation system installed, and a dehumidifier added to maintain conditions going forward. This full scope may seem significant, but it addresses all the interconnected issues at once rather than returning to fix one problem at a time over several years.
