Questions worth asking Professional Insulation LLC
Does Professional Insulation LLC hold a Washington contractor registration?
Registration PROFEIL865CC is the one to check, and it expires January 2028. It is Professional Insulation LLC's, filed with Washington State L&I. That was current on the state record as of September 14, 2026 — the link on this page goes to the record itself. On file alongside it: a $15,000 contractor bond (RLI Ins Co) and $1,000,000 of liability insurance with WESTERN NATIONAL MUTUAL INS CO through May 2027. Ask them to send the bond and insurance certificates over before the first day on site.
What areas does Professional Insulation 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.
