"I’ve had several jobs done by Stew and he’s an excellent plumber. He’s put in a water heater, done several smaller jobs, and even responded to emergency situations. He doesn’t believe in shortcuts and has very fair pricing. Not sure why the previous poster had such issues. As to the issues with his phone, I know his business has had phone issues with the provider. Those are all resolved. I won’t go to anyone else for plumbing."
