Crawlspace Insulation
in Pitt Meadows, BC
Pitt Meadows occupies the flat delta land between the Pitt River and the Golden Ears foothills — historically some of the most productive agricultural land in BC, and now increasingly a mix of residential neighbourhoods, industrial areas, and protected agricultural reserve. The residential community is relatively compact, centered around the Downtown Pitt Meadows core and the residential streets extending south and west. The low-lying position of the entire municipality means water table management is a consistent concern in any crawlspace context.
The majority of homes in Surrey and the surrounding communities built before 2000 have fiberglass batt insulation installed between the floor joists in the crawlspace. When this insulation was new and dry, it provided reasonable thermal resistance. The problem is that fiberglass batts installed in a vented crawlspace environment in a high-rainfall climate like ours rarely stay dry. They absorb ambient moisture, sag out of their cavities, and gradually collapse onto the ground. Wet fiberglass insulation has essentially zero R-value, adds weight that can pull down on vapor barriers or staples, and provides a hospitable nesting environment for rodents.
For crawlspaces that are not being fully encapsulated, we install new unfaced fiberglass batts or mineral wool between the joists, but only after addressing the moisture conditions that destroyed the previous insulation. Installing fresh batts into a still-damp crawlspace environment means you'll be back in the same situation within a few years. Proper sequencing matters: drainage, vapor barrier, then insulation.

About Pitt Meadows — What We See Here
Homes in Pitt Meadows built on the flat bottomland sit in an area where the water table is very close to grade for much of the year — similar to parts of Richmond and South Delta. Sump pump systems are not optional in these conditions; they are a fundamental requirement for keeping crawlspaces dry. The flat topography also means that exterior grading improvements have limited effectiveness — there is simply not enough slope to move water away from foundations by gravity alone, which makes interior drainage and pumping more important here than in hillside communities.
The proximity to the Fraser River and Golden Ears Provincial Park means Pitt Meadows receives significant precipitation funnelled by the valley, and the community's storm drainage system must handle large volumes of water during major weather events. We design crawlspace drainage systems for Pitt Meadows properties to handle the full wet-season load, not just average conditions — sizing sump pumps conservatively and including battery backup as standard practice.
