We did this last year and got quotes from both Sweeney’s Plumbing (206-551-6465) and Paul Lewan from Stalwart Plumbing (206-784-3747). They were equal quotes and the gentlemen had equally good vibes. We went with Paul Lewan but would go with with either plumber in a similar situation again. Incidentally, we got a permit for the gas line and Lewan’s work passed no problem. (And now we love our gas stove!)
