Blower Door Testing in Puyallup and South Hill

Puyallup and South Hill see steady ADU and addition permits that call for blower door testing under the Washington State Energy Code. WA Blower Door provides third-party residential tests ($375) and multi-fan setups when the house needs more than one fan. We’re based in Sumner, a short drive up the valley — free within 20 miles, $1.75/mi after that.

Puyallup is one of the busiest residential building areas in Pierce County, from infill homes and ADUs in the valley neighborhoods around downtown to new subdivisions up on South Hill. WA Blower Door is based next door in Sumner, so Puyallup projects are a short drive for us. We provide third-party blower door testing and the written results your builder and inspector need to close out the energy code air leakage requirement.

Testing tips for builders: If you're running several homes in a Puyallup or South Hill plat, schedule each test once the house is fully trimmed out: windows and doors latching, hatches weatherstripped, and fans and range hoods installed with dampers. A pre-drywall walk-through to catch big leaks early can also pay off on a new plan. Ask us about it when you book. The full prep checklist is on our Residential Testing page.

What if the house misses the target? We'll walk you through where the biggest leaks are likely coming from so your crew knows what to seal. Then schedule a retest.

Puyallup FAQ: Does my ADU need a blower door test? New ADUs often do under the Washington State Energy Code, depending on the project. Your plan review comments will usually say so, or call us with your permit details at (253) 802-8738.

Do you test in Sumner and Tacoma too? Yes. See our Sumner and Tacoma pages, or our Pierce County page for unincorporated areas.
