Crawlspace Encapsulation
in Willowbrook, BC
Willowbrook is the commercial and residential hub of the Langley Township's western end, centred around the Willowbrook Shopping Centre and extending into the residential streets between the Langley Bypass and Fraser Highway. The residential areas here are a mix of older homes from the 1970s and 1980s and more recent construction, with crawlspace conditions that vary accordingly.
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 Willowbrook — What We See Here
The proximity to commercial and arterial road development means that some Willowbrook properties have experienced changes to their drainage patterns over time as neighbouring parcels were developed and graded. Residential properties adjacent to commercial developments sometimes find that surface water from adjacent parking lots and hardscaping redirects toward their foundations in ways that were not an issue before the commercial development was built. We account for these modified drainage conditions when designing solutions for affected properties.
