Crawlspace Encapsulation
in Morgan Creek, BC

Morgan Creek is a master-planned golf course community in South Surrey with a concentration of larger, custom-built homes from the late 1990s and 2000s. While newer construction generally has better vapour control than older housing stock, Morgan Creek properties are not immune to crawlspace moisture issues. The community's proximity to multiple water features — ponds, streams, and wetlands associated with the golf course — means the ambient water table is higher than in other South Surrey areas, and seasonal fluctuations can be significant.

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.
