Questions worth asking Black Widow Construction LLC
Does Black Widow Construction LLC hold a Washington contractor registration?
Registration BLACKWC771NQ is the one to check, and it expires February 2028. It is Black Widow Construction LLC's, filed with Washington State L&I. That was current on the state record as of September 7, 2026 — the link on this page goes to the record itself. On file alongside it: a $30,000 contractor bond (Nationwide Mutual Ins Co) and $1,000,000 of liability insurance with State National Ins Co Inc through February 2027. Ask for proof of bond and current insurance before work starts.
Does Black Widow Construction LLC cover my part of Spokane?
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.
