What People Say About Us
Peri is awesome. He is extremely responsive and did an excellent job on our bathroom renovation. I recommend going with him and I will be using him for all our plumbing needs in the future.
The service was great. I called Peri from Proto Home Service Plumbing for a clogged kitchen sink. After inspecting some pipe connectors/drainage, he realized that some connections were wrong. He took the time to explain everything in detail that needed to be changed. I followed his recommendations and I'm very happy with the results. Peri is very professional with many years of experience. Highly recommend!!
Peri was amazing! He was super informative and gave me an estimate right off the bat. The service was fast and the price was very reasonable. I will definitely be using Proto Home Service again!
Clean, professional work. They were quick to respond and took the time to explain the new tank’s operation. We had an oil hot water tank replaced (which most plumbers can't/won't do). Great work. Thank you.
I recently had Peri from Proto Home Service Plumbing handle all the plumbing work for my bathroom renovation, and I couldn't be more impressed! He installed a brand new walk-in shower, infinity drain, toilet, and faucet with absolute precision and care. What stood out most was the excellent quality of his work combined with his professional attitude and very reasonable rates. Throughout the entire project, Peri demonstrated exceptional skill and attention to detail...
Our water heater gave out unexpectedly. Peri and his team were there in less than 18 hours to replace it. He is very responsive and he will always be my first call when anything plumbing or heating needs attention.
These guys are AMAZING. If you’re looking for someone who is both knowledgeable and super-responsive, these are your guys. They have dealt with some super janky plumbing for me in a couple of old buildings and they did a phenomenal job. Trustworthy and reasonably priced. Hard combination to beat.

The Benefits of Tankless Systems
Tankless water heaters provide hot water only when needed, rather than storing it in a tank. This design allows homeowners to enjoy continuous hot water while improving overall energy efficiency.
Because water is heated on demand, tankless systems can reduce standby energy loss commonly associated with traditional tank models. They also take up less space, making them a practical option for many homes.
For households seeking improved efficiency and modern performance, tankless systems offer a reliable and space-saving solution.
━ PROFESSIONAL INSTALLATION AND REPLACEMENT ━
