Dehumidifier Installation
in Burke Mountain, BC
Burke Mountain is one of the most recently developed residential areas in Coquitlam, with construction ongoing on the steep slopes of Burke Mountain above the existing Coquitlam community. Homes here are built on terrain that was forestland until recently, on soils that are a mix of shallow glacial till and organic forest soils. The steep topography creates significant drainage challenges, and the cut-and-fill grading required on these lots alters natural drainage patterns in ways that can produce unexpected water intrusion for individual properties.
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 Burke Mountain — What We See Here
Because Burke Mountain development is recent, the crawlspace issues we address here are different from the decades-old moisture damage we encounter in older communities. The challenges are more often about site drainage design — fill areas that have not drained as intended, grading that channels runoff toward foundations, and drainage systems that were adequate under normal conditions but overwhelmed during the heavy storms that are increasingly common in this region. Proactive assessment and drainage correction are the right approach for Burke Mountain homeowners.
