The attention to detail is like nothing I have ever experienced.

My brother recommended ProMax and I couldn’t be more pleased by the job that was done! Evan is awesome to work with and does very high quality work. My bathroom was completely gutted and he came in and had great ideas that fit my budget. He put all new plumbing in for a free standing tub and walk in tile shower. The attention to detail is like nothing I have ever experienced. I would use ProMax again in a second!

100% happy with their work and would hire them again in a heartbeat

Evan and Owen showed up on time, were super polite and professional and worked hard all day long on a fairly complex installation of a brand new tankless water heater in a different part of my basement from where the old tank heater was located. The quality of their work was flawless and everything looks so neat and tidy. I had even forgotten one request I had made to brace the gas meter on the outside of the house during the pre-work walk through with Evan. Well, Evan and Owen didn’t forget and they took care of that issue as well. Last but not least they cleaned up everything to a “T” before they left well into the evening. I strongly recommend ProMax Heaters and Plumbing. I am 100% happy with their work and would hire them again in a heartbeat. If you are looking for a quality install at a fair price and done by pros, look no further.

I cant recommend this business enough

Being without a kitchen for 4 months after a pipe break, I called ProMax and Evan answered the phone and immediately got me into his schedule which was the next day. Yay! He was friendly, efficient and got the job done. I cant recommend this business enough.
