Dehumidifier Installation
in Coquitlam Center, BC
The Coquitlam Centre area — surrounding the regional shopping mall and extending into the adjacent residential streets — has a mix of housing types from the 1970s and 1980s that represent the period when this part of Coquitlam transitioned from low-density suburban to more urban character. Single-family homes on crawlspace foundations from this era are common in the streets surrounding the commercial core.
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 Coquitlam Center — What We See Here
The soil conditions in central Coquitlam are predominantly clay-loam, similar to other mid-slope communities in the Tri-Cities area. Drainage is better than in the flatland communities to the south but still prone to surface water accumulation after heavy rain events. We work regularly in this area on encapsulation and mold remediation projects for homes that have accumulated moisture damage over the decades of their existence.
