Questions worth asking SD Plumbing LLC
Is SD Plumbing LLC a registered contractor?
Yes — SD Plumbing LLC holds Washington State (L&I) contractor registration SDPLUPL750RR, 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 $6,000 contractor bond (Western Surety Co) and $1,000,000 of liability insurance with State National Ins Co Inc through December 2026. Ask them to send the bond and insurance certificates over before the first day on site.
What areas does SD Plumbing 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.
How does a business get listed on this site?
SD Plumbing LLC is licensed and working in the Spokane area — that's the whole bar for a page here. 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.
