Yes — Testcomm LLC holds Washington State (L&I) contractor registration TESTCL*044QK, expiring November 2026. We checked it against the state record on September 14, 2026; the same lookup takes you about a minute if you want to see it yourself.

Ask for proof of bond and current insurance before work starts.
What areas does Testcomm LLC serve?
Spokane is what they cover. A crew close to you is the one that comes back for a warranty call, so it is worth asking how far out they really travel.
