"I had Rob install a tankless hot water heater, whole house water filter, and run a new gas line for my gas stove conversion. He was very professional and and was quick to set an appointment. The whole job took a single day and he even removed and disposed of the old outdated appliances. Quality work at reasonable prices! Would highly recommend."

"Called with an issue with my furnace, they were the only company to actually answer the phone. Professional customer service and prompt scheduling. Gave me an honest estimate and proceeded with the job that day. Would recommend to anyone needing service or a new system installed! 10/10!"

"Great team and great job from start to finish. The estimator was personable and knowledgeable and we received a good quote to get propane service installed, a new on demand tankless water heater and future service line for a propane fireplace. Great job from start to finish, would hire them again. Bill, Kennebunk"

"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!"

"My only complaint was when I made the call I was not told that there was a service fee - that is not right! The guys that installed the water heater were great and left no mess - they get 5 stars â­ ï¸"

"We were very pleased with the communication and the outcome of our project. We have an old home with some older piping. Finding someone that works on steam boilers is tough. When they looked at the install, they explained what needed to happen clearly deand unrstandable."

"Tyler was extremely helpful and accommodating and helped me on very short notice with 2 plumbing projects recently, even spending almost an entire Saturday working when a washing machine install ended up being more work than expected. He is professional and extremely reasonably priced. Will definitely recommend and use for all of my plumbing needs."

"Great! The owner, DF Richard, came out personally before our first filling to introduce himself and explain everything. Shortly afterwards, we had a wicked bad storm and lost power for 2 days, so we really needed the propane. They even topped off my tanks during the power outage, not because I called, but because the driver was in our area and wanted to be sure that we had enough fuel to keep our generator running until power was restored. Awesome customer service!!"

"Scheduling was challenging. On the first attempt, the service guy never arrived. When I called, the scheduler said there was some computer error, apologized, and rescheduled. On the second attempt, the guy came and did the service, then recommended having the expansion tank replaced. I was supposed to get a call to schedule the follow-up service, but never did. I called a few times and left a message, eventually getting a callback from someone who was able to schedule the service. Once again, the first attempt was a flop. They sent out a heating technician, not a plumber, to replace the expansion tank, which he was not certified to do...and he arrived late. On the second attempt, the plumber arrived on-time. He was very professional, efficient, and did great quality work. He made a recommendation for some other plumbing work after I asked him about an issue we had been having. He told me to call the company to schedule the work. Once again, I struggled to even get the service scheduled. This time, I gave up after 3 or 4 tries. I'll be contacting another plumber to get the work done at some point."
