I was impressed with Mario's responsiveness to all my questions and the quality of materials and workmanship that he provided. Mario was meticulous with his crew's work and fitting everything exactly. He took care of our property during the replacement and installation of the new water heater, and cleaned everything up at the end. He met the schedule and finished the project in one day. My new water heater is running efficiently. Thanks, Mario! I highly recommend Universal Plumbing!!

When our water heater stopped working, I contacted Mario late night. He was able come first thing in the morning and fix it up. He was responsive, punctual and effective. I highly recommend him and will be holding on to his contact for future plumbing needs.

It wasn’t cheap. But it got fixed quick and I plan on calling him again if a plumbing issue comes up. That tells you all you need to know!

Mario did a great job in replacing a leaking P trap under a shower. Timely, reasonable and even went to the extent of being able to patch up the ceiling.
