Best General Plumbing Diagnosis And Checkup in Seattle WA

I asked Craftsman for a quote on installing a dishwasher hookup, and the quote they gave me was exorbitant. But more importantly, while the plumber was there, he told me my water heater flue was incorrectly angled, which could one day cause a carbon monoxide leak (although he didn't detect one, and none had been detected in the 16 years the flue had been that way) and that per Craftsman company policy he had to shut off my gas and my neighbor's gas, knowing full well that I'd turn it on right after, because I'm not going to live (or force my neighbor to live) without hot water while waiting for a new flue to be installed. Also that this was very common and that he'd already done it 3x that week at other homes. It took me over an hour to relight the water heaters after he left. Pretty annoying to hire a plumber, have the plumber break something unrelated to the service call, and need to spend so much time fixing it on my own afterward.
