"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."

"Justin at County Line Plumbing and heating came out shortly after I called the office. Due to my leaking 50 gallon water heater started leaking! He added the situation and installed a new Rinnai on demand water heater later that day!!! Not only was the price fair, but he explained everything every step of the way! Highly recommend 10 out of 10"
