I have been a customer/client of BOSS Plumbing for more than 6 years, ever since I moved into my house. They do excellent work, are very friendly, and explain everything. For many projects, Byron has been my technician and he’s GREAT. I will always ask for Byron.

Kevin was amazing and fixed my kitchen sink fast and efficiently!

My shower had very low pressure, and a few plumbers took a look at it and claimed I had to open the wall and replace it. Instead, Boss Plumbing managed to fix the pressure without opening the wall, and at a much cheaper price. I have since used them for a few other issues, and have only had great experiences.
