Dehumidifier Installation
in Haney, BC

Haney is the historic town centre of Maple Ridge, situated on the benchland above the Fraser River. The older residential streets of central Haney — particularly the area around Haney Place and the historic commercial district — have housing stock dating from the early 20th century that represents some of the oldest residential construction in our service area east of New Westminster. Crawlspaces in these homes have had a very long time to accumulate moisture-related damage.

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.
