Bill M.

"I couldn't be more pleased with this outfit...Unlike almost every other plumbing company I contacted to do a seismic valve installation at our condo, Seismic Shutoff gave me a bid for the work without requiring a $90 on-site inspection just to submit a bid -- which is unfeasible for people who reasonably try to get multiple bids for a costly project." - Yelp
