Insulation & Air Sealing in Hillsboro, OR

Insulation without air sealing is like wearing a warm coat full of holes. In a city growing as fast as Hillsboro, that shows up two different ways. Newer homes in developments like South Hillsboro are usually built to current energy code, but even new construction can have gaps around penetrations and fixtures that weren’t sealed correctly. Older homes closer to the original downtown, which has been incorporated since 1876, are more likely to be under-insulated by today’s standards altogether.

What that means day to day: rooms that never quite match the thermostat, drafts around older windows and doors in the city’s established neighborhoods, and a heating system working harder than it should. 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, regardless of how old the house is.
