Air Sealing

What This Service Involves

Air leaks around top plates, recessed lights, ducts, and penetrations can waste a large share of the energy you pay for. We locate those leakage paths and seal them with caulk, foam, gaskets, and weatherstripping matched to each location. Sealing the envelope also keeps damp outside air and its moisture from migrating into wall and attic cavities, a real concern in our marine climate. Homeowners typically notice steadier room temperatures and a quieter interior almost immediately.

Benefits

Cuts conditioned air loss through hidden gaps; Balances room-to-room temperatures; Keeps humid outdoor air from entering wall cavities; Improves the performance of any insulation upgrade; Lowers strain on heating and cooling equipment

Our Process

1) Identify leakage points at the attic, basement, and living-space penetrations; 2) Seal large bypasses first, then finish smaller gaps; 3) Weatherstrip movable components like hatches and doors; 4) Confirm results with a follow-up draft check

What Affects the Cost

Home age and construction type; Number of penetrations and can lights to seal; Attic and crawlspace accessibility; Whether ductwork sealing is included; Extent of existing insulation to work around

Best Time of Year

Any season works, though cool months make drafts easy to locate and confirm.
