"Excellent. The serviceman arrived on time, was knowledgable. He explained what he was doing. He went right to work and completed his work in an appropriate amount of time. Very pleased with their work. Already set up an appointment for the fall heater tuneup!"

"Hired Mitchell to replace the kick heater in my kitchen. The original heater was installed first, before our kitchen island was installed. A real tough job to replace. He did a wonderful job with the new heater and I am 100% satisfied with his workmanship. Will hire him on future plumbing and heating jobs."

"I called Rowells Services to have an in-house drain unclogged. I was able to get an appointment that afternoon which was great. I was told that I would get a call when the techs were on the way. That did not happen , but they arrived that afternoon as planned. They immediately assessed the situation and elected to run a camera on a snake through the drain pipe. To do this they had to remove the toilet. They found the clog and cleared it. Verified that the drain was open and then reinstalled the toilet. They did a very nice job of cleaning up after themselves and left within one hour after arriving. This is all the good news. The bad news is they did not check for leaks when they reinstalled the water line to the toilet. The next morning we had water dripping from the slow leak in our finished cellar. I found the source of the leak and tightened the connection myself."

"We refurbished two bathrooms as we were getting ready to sell our house. Bourne Plumbing was right there with us. They solved some design problems with the remodel and helped keep the project on time and on budget. Great to work with and would highly recommend them for any remodel project!"
