Crawlspace Encapsulation
in Aldergrove, BC
Aldergrove is an agricultural-edge community on the eastern flank of Langley Township, close to the BC-Washington border and the Aldergrove Lake Regional Park. The residential core has a small-town character with housing stock from the 1950s through the 1970s, and the surrounding area transitions quickly to agricultural land and acreage properties. The soils in the Aldergrove area are a mix of silt loam and clay, with drainage characteristics that vary with topography across the community.
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 Aldergrove — What We See Here
Rural and semi-rural properties around Aldergrove often have crawlspaces that have had minimal professional attention over their lifetimes. Older farmhouses and rural residences in this community may have the most challenging conditions we encounter: very old structural wood, improvised moisture control measures applied over the decades, and rodent or pest damage that has never been properly addressed. We bring the same thoroughness to rural Aldergrove properties as to suburban homes closer to the Langley core.
