Very transparent service with both Brooke and Ricky providing a detailed breakdown of the plumbing fix and cost associated with it. Andrew the tech did a great job of explaining the issues (leaking pipe, and then boiler maintenance including replacing boiler feed valve, expansion tank and relief valve, and repiping the feed line, replace circulator flange) and providing quick efficient work.
I had my water filtration system updated the other day, the technician noticed I had a leak beneath my sink. After searching I settled upon the company Fix a Leak. I sent photos of my issues to Rick the manager. (My house is old from the 1930s and very tricky). Rick sent Daniel, a highly experienced pro plumber. I showed Daniel what needed to be done. New faucet for the kitchen and I also needed a new master valve for the water coming in to the house along with replacing some additional old valves in the basement. Daniel did an amazing job and even corrected the grounding for the wiring around the pipes. Once everything was done, he made sure there were NO leaks and that all components were working properly. You need a plumber? Get the best at Fix a Leak!

Met with Daniel for a service call I made regarding shower system. He came, looked at the issues we were having and provided his recommendations. He seemed knowledgeable and a trusted partner. If needed for any future plumbing work, I will call fix-a-leak again.

I had a leak and clog in my bathroom sink. Andrew the tech came in and assessed the situation and completed the job in a timely manner. He was very professional and knew what he was doing. I called a few other plumbers and they want to break walls to assess a simple fix. Thank you Andrew for your professionalism and integrity.
