Crawlspace Insulation
in Fort Langley, BC
Fort Langley is a designated heritage community on the south bank of the Fraser River, known for the Hudson's Bay Company fort and the historic village that grew up around it. The residential streets near the historic core contain some of the oldest surviving homes in the Fraser Valley, with some properties dating back to the late 19th century. These homes are of significant heritage value, and any crawlspace work in this community must be approached with an understanding of the historic building methods and materials involved.
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 Fort Langley — What We See Here
The Fraser River proximity gives Fort Langley a high seasonal water table in the lower-lying areas near the waterfront, while the residential streets on the higher ground above the village are somewhat better drained. Heritage homes near the river have often had repeated moisture issues over their long lives, and the crawlspaces in some of these properties have layers of remediation attempts by previous owners. We bring a careful, systematic approach to understanding what is actually present before designing any new intervention.
