Questions worth asking Hydrosci LLC
Does Hydrosci LLC hold a Washington contractor registration?
Registration HYDROL*927D6 is the one to check, and it expires April 2028. It is Hydrosci 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. L&I also lists a $4,000 contractor bond (Old Republic Surety Co). Ask for proof of bond and current insurance before work starts.
Does Hydrosci LLC cover my part of Spokane?
Mead 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.
Why is Hydrosci LLC listed here?
Hydrosci LLC is licensed and working in the Spokane area — that's the whole bar for a page here. The registration gets checked against the state's record and the date sits on this page, so you can judge how current it is.
