Crawlspace Insulation
in Maple Ridge, BC
Maple Ridge sits at the base of the Coast Mountains on the north bank of the Fraser River, with residential development spanning from the flat benchland near the river up into increasingly steep terrain toward the mountain front. The community receives significant precipitation — positioned to catch heavy orographic rainfall from Pacific systems moving against the mountain barrier — and the soils in the lower agricultural fringe areas that have been converted to residential use are often poorly drained organic-clay mixes that stay saturated for extended periods in winter.
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 Maple Ridge — What We See Here
The Hammond area near the river and the Haney town centre core have the oldest residential stock in Maple Ridge, with some homes dating to the early 1900s. Crawlspaces in these homes have weathered nearly a century of Maple Ridge winters, and original structural elements have often been repaired multiple times. We look carefully at the bearing condition of all structural members in these older homes — not just whether they look sound visually, but whether the footings they rest on are still at grade and providing adequate support.
Silver Valley and the newer uphill developments have a different profile: homes built in the 2000s and 2010s on steeply sloped lots where construction required significant cut-and-fill grading. When fill is placed against a foundation and not adequately drained or compacted, it can direct surface water toward the crawlspace for years after the home is occupied. We see this pattern in a number of newer Maple Ridge homes, and the fix is typically an exterior perimeter drain system that intercepts water before it reaches the foundation wall.
