WA Blower Door is based right here in Sumner, at 16202 64th St E, Suite 117. That makes Sumner the closest thing we have to a home field. Whether you're a builder finishing a spec home in the valley, a homeowner wrapping up an ADU behind a house near downtown, or a remodeler whose permit calls for air leakage testing, we're usually just a few minutes away.
Most new homes permitted through the City of Sumner need a Washington State Energy Code air leakage test before final inspection, and some additions and remodels do too, depending on scope. We provide the third-party blower door test and written results you can hand to your builder and inspector. If you're not sure whether your permit needs a test, check your plan-review comments or call us with your permit number and we'll help you sort it out.
What we see on Sumner projects
New single-family homes
The usual suspects are attic hatches, recessed lights, plumbing and electrical penetrations, and rim joists.
ADUs and garage units
Small volume means small leaks matter more. Garage-to-living-space connections and the shared walls need attention.
Additions
The seam where new framing meets the old house is a common leak path.
