Insulation & Air Sealing in Oregon City, OR

Insulation without air sealing is like wearing a warm coat full of holes. Oregon City has been an incorporated city since 1844, the oldest in the Pacific Northwest, and that long history means the city’s housing spans a genuinely wide range of construction eras, from historic homes near Canemah and the McLoughlin neighborhood to newer hillside and outlying developments. The insulation and air sealing gaps in any given house depend a lot on when and how it was built, but the underlying fix is the same: seal the envelope before adding more insulation on top of it.

What that means day to day: rooms that never quite match the thermostat, drafts around older windows and doors, and a heating system working harder than it should in a climate with cool, damp months for much of the year. Adding insulation without addressing air sealing underneath it rarely solves the problem on its own. We treat the two as one job because that’s how building science works.
