Don Dowling plumbing does amazing work! Max M in particular is extremely knowledgeable and professional. They helped me install a new water heater, hook up our washer and drier, install a new water softener, unclog a clog in the main waste line, and serviced my steam heater system and radiators. Fair price and great service! Five stars

Don Dowling was a pleasure to work with! I was in the need of a hot water heater/furnace replacement and Don was the man for the job! I heard good things about Don Dowling Plumbing from a friend of mine so I gave him a call. His installation and knowledge of the job was above and beyond. 10/10 would recommend for jobs big and small!
