Crawlspace Encapsulation
in Haney, BC
Haney is the historic town centre of Maple Ridge, situated on the benchland above the Fraser River. The older residential streets of central Haney — particularly the area around Haney Place and the historic commercial district — have housing stock dating from the early 20th century that represents some of the oldest residential construction in our service area east of New Westminster. Crawlspaces in these homes have had a very long time to accumulate moisture-related damage.
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 Haney — What We See Here
The benchland position of Haney gives it better drainage than the river-adjacent communities of Hammond and Pitt Meadows, but the clay-loam soils still drain slowly enough that persistent crawlspace moisture is common. Encapsulation with dehumidification is effective in this area without necessarily requiring the heavy-duty sump systems needed in the floodplain areas.
