Lights Out Concrete Demo LLC.

Yes — Lights Out Concrete Demo LLC holds Washington State (L&I) contractor registration LIGHTOC752R6, expiring December 2027. 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. The same record shows a $30,000 contractor bond (American Contractors Indem CO) and $1,000,000 of liability insurance with Third Coast Insurance Company through December 2026. Ask them to send the bond and insurance certificates over before the first day on site.

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.

Licensed, and working in Spokane. That is the bar for a page on this site, and Lights Out Concrete Demo LLC clears it. We check that registration against the state's own record and date the check on this page, so you can see for yourself how current it is.
