Hired on Thumbtack

After my hot water tank leaked and flooded the basement , Mitch and Chris helped us put a pair of tankless water heater in our basement. Their installation was a precision work of engineering with top quality materials. This was done at a competitive price and they were able to get me on their schedule within a few days. When they couldn’t get a part, they made sure to stay late and finish the job as promised. Overall , a terrific experience and I wouldn’t hesitate to hire them again!

Details: No, the location does not have an existing heater • Gas tankless • I would like to discuss with the professional • House

Coy Plumbing was able to service our heater within about 24 hours. Mitch, our technician kept us updated on his arrival time. He diagnosed the issue and performed the repair in about an hour. He was clean and courteous and a pleasure to have in our home. He provided recommendations on how to address potential future issue.
