Sealing the Gaps for a Healthier Home

Air leaks in your home’s crawlspace or attic can cause poor air quality and high energy bills. PNW Eco Insulation's air sealing services focus on locating and sealing gaps, nooks, and open seams that allow unwanted air to enter or escape. From attics to crawlspaces, we ensure every hidden space is sealed correctly to improve your home's comfort.

Crawl Space Protection FAQs

How does air sealing lower energy bills?
Air sealing closes gaps where heated or cooled air escapes. Older homes in Everett, Arlington, and Burlington often lose significant conditioned air through attics, crawl spaces, and ductwork joints. Once sealed, your heating and cooling system maintains temperature with less effort, directly reducing monthly energy costs.
What is a blower door test?
A blower door test pressurizes the home to measure how much air is leaking and locate where it is escaping. It is the most reliable diagnostic tool before air sealing begins and helps ensure that the right areas are targeted for the best results.
What are the most common air leaks in a home?
The most common leaks occur around attic penetrations, recessed lighting, plumbing and wiring openings, ductwork joints, attic hatch covers, and crawl space access points. These gaps are often invisible but can add up to the equivalent of leaving a window open all year.
Do you seal air leaks in both attics and crawl spaces?
Yes. Attics and crawl spaces are where the largest leaks are typically found. We seal gaps around wiring, plumbing, ductwork, and framing joints throughout the home. In Bellevue and Redmond, where many homes have been remodeled multiple times, crawl space air sealing often yields the biggest efficiency gains.
Can air sealing improve indoor air quality?
Yes. Air sealing prevents dust, outdoor pollutants, and unfiltered air from entering through hidden gaps. For homes near major roads in Everett and Arlington, this is especially valuable. Households with allergy or asthma sensitivities often notice a meaningful improvement in air quality after sealing is complete.
