Drainage Solutions
in Langley, BC
Langley encompasses both Langley City — a small, densely developed municipality with established residential neighbourhoods — and the much larger Langley Township, where residential development spans from urban infill near Willowbrook to rural acreage properties in Brookswood, Salmon River, and Aldergrove. Crawlspace conditions across this range are quite diverse. The Willowbrook and Walnut Grove areas have significant numbers of homes built in the late 1980s and 1990s on relatively flat ground with clay subsoils, while the agricultural fringe areas are more variable, with some properties on older farmland with organic soils that are slow to drain.
Drainage problems in crawlspaces have two distinct origins: water that arrives from outside (surface runoff, failed exterior drainage, high water table) and water that condenses from the air inside the crawlspace onto cooler surfaces. The solutions for each are different, and correctly diagnosing which problem you have — or which combination — is the critical first step. Applying interior drainage solutions to an exterior water problem provides partial relief at best; addressing the exterior source is far more effective and usually less disruptive.
Interior drainage systems — perimeter drain tile installed inside the crawlspace along the base of the stem wall — are the right solution when exterior work is impractical (due to finished landscaping, hardscaping, or very tight site conditions) or when the primary issue is groundwater rising from below rather than surface water entering through the wall. Interior drain tile channels water to a sump pit where a pump removes it. This approach does not stop water from entering the foundation, but it manages it effectively once it does.

About Langley — What We See Here
The Langley City core has housing stock dating back to the early 1960s, with some of the most significant moisture and structural issues we see in the region. Crawlspaces in homes of this era were built with wood posts sitting directly on concrete pads — sometimes directly on soil — and fibreglass batt insulation that was marginal even when installed. After six decades of Pacific Northwest rainfall cycling through these crawlspaces, the moisture damage in original structural wood can be substantial. We often find multiple post replacements needed alongside encapsulation when working in the city core.
Fort Langley and Murrayville present heritage preservation considerations that add complexity to crawlspace work. Older homes in these communities sometimes have original construction methods and materials that require care to work around without damaging historically significant elements. We approach these jobs with that context in mind, matching repair materials to the era of the structure where possible and being conservative with interventions that could affect the character of the building.
