Dehumidifier Installation
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.
Humidity management is the operational heart of any crawlspace encapsulation system. Sealing the crawlspace envelope stops the major sources of moisture entry, but the residual humidity in the sealed space — from the soil itself, from diffusion through concrete stem walls, and from any minor air leakage — needs somewhere to go. In most Lower Mainland crawlspaces, a properly sized commercial dehumidifier running continuously is the right answer. The target is to maintain relative humidity at or below 50 to 55 percent year-round, which is the threshold at which mold growth and wood-boring insect activity become effectively impossible.
Proper sizing is critical. An undersized dehumidifier will run continuously without reaching the setpoint humidity level, eventually burning out its compressor. An oversized unit is not a problem in terms of dehumidification, but it costs more upfront and uses more energy than necessary. We calculate required capacity based on crawlspace square footage, current moisture load (as measured during inspection), the vapor barrier coverage and sealing quality, and the seasonal humidity patterns typical for the specific location.

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.
