Crawlspace Encapsulation
in Hammond, BC
Hammond is one of the oldest settled communities in Maple Ridge, located near the Pitt River and the Fraser River confluence. The flat bottomland position means water management is a significant concern — the area was historically prone to flooding before modern dyke systems were established, and the water table remains high through the wet season. Older homes in Hammond have dealt with challenging moisture conditions for decades, and many have accumulated significant crawlspace damage as a result.
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 Hammond — What We See Here
The proximity to the river means that Hammond homes should be designed for worst-case water table conditions, not average conditions. We size sump systems here to handle peak spring freshet conditions when both rivers run high and groundwater across the floodplain rises correspondingly. This larger-capacity approach costs marginally more upfront but provides the margin of safety that the location demands.
