Why Air Duct Sealing Matters
Even small cracks or gaps in your ductwork can cause up to 30% air loss, forcing your HVAC system to work harder and increasing energy costs. Proper sealing keeps conditioned air where it belongs—inside your living spaces.

FAQs for Attic & Crawl-Space Insulation Revitalization in Vashon
How do you handle insulation work in homes with limited attic or crawl-space access?
We start with a careful assessment of access points and clearances, then plan the safest approach for removal, air sealing, and installation. Our goal is to restore performance without unnecessary disruption, even in tight spaces.
Can insulation revitalization help with salty, damp air and musty odors on Vashon?
Yes. When moisture is part of the problem, we address crawl-space conditions first with vapor barrier upgrades, sealing, and ventilation corrections as needed. This helps protect new insulation and reduces musty odors that can move into living areas.
What is the benefit of air sealing before adding new insulation?
Air sealing blocks the gaps that let conditioned air escape and outside air enter. Once leaks are sealed, insulation works more effectively, comfort improves, and your heating system does not have to work as hard.
