Edwardo did a plumbing job in my kitchen. Super efficient. Clearly knew exactly what was needed and did it. Very careful clean and organized. He was also extremely good at explaining what and why he was doing specific steps. In addition he pointed out a few other areas that may be issues in the future for me to keep an eye on. Lastly, Edwardo was pleasant and easy to talk with, a genuine nice guy.

I had the nicest experience today with Arturo the tech. He was so darned cheerful & nice from his introduction and then on to being very professional. He provided fast service and took the time to explain about plumbing and your service.
He’s really a very nice person and I appreciate having someone like him come into my home.

We had a whole house water filtration system installed . Jace did a terrific job and explained everything he did. He also fixed my tankless water heater that was having an error code that was not completely addressed in the owners manual after I tried to fix it myself. I would recommend Jace and Mauzy to my friends and neighbors. I’m very satisfied!

This is the second time I have used Mauzy plumbing. My plumber Eduardo, was an absolute professional. He was incredibly good at his work, went above and beyond. Eduardo was so friendly, helpful and communicative. He took care to do the job to the highest standards. I highly recommend the company because of Eduardo and the staff at the office. Thank you.
