Insulating Ferndale.
Ferndale sits on the Nooksack river-valley flats northwest of Bellingham, and the high water table there makes moisture the defining issue. The soft, damp lots mean crawlspaces flood or stay wet much of the year, floor insulation gets soaked and falls, and old insulation in these homes is frequently moisture-damaged and needs to come out. Cold floors are nearly universal, but the root cause is almost always water sitting in or under the crawlspace.
So the recurring work in Ferndale is moisture-first: vapor barriers and crawlspace encapsulation to deal with the high water table, floor insulation once the ground moisture is controlled, and removing moisture-damaged insulation before anything new goes in. For the wettest lots we seal the crawlspace, handle the standing water with drainage, and add a dehumidifier. Insulating a Ferndale floor without first controlling the water is a guaranteed re-do, so we always handle the moisture first.

Popular jobs

Moisture & prep considerations
Like everywhere in Bellingham, we air-seal and get the moisture under control before we insulate. In Ferndale that means paying close attention to high water table, wet crawlspaces, then insulating to current WA energy code.
