Crawlspace Insulation
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.
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 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.
