"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!"

"The plumber was professional, courteous and did a good job. However, it was unreasonably expensive. $550.00 to replace the cartridge in my shower faucet. The work took about 1 1/5 hours including about 40 minutes to go pick up the part. I was charged an additional $140.00 just because he did not have the part with him. My faucet is a very common Kohler faucet."

"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."
