“I had a burst pipe in my basement on Christmas Eve and after calling 10 plumbers, Everest Mechanical was the only company to give me the time of day! Shelly was very accommodating and even though it was Christmas Eve and she had her own burst pipe, she figured out a way to get her plumber, Manny to my house that night to save Christmas! Manny was arrived exactly when they said, was very professional and did a high quality job. He took the time to explain mitigation steps to avoid a future pipe burst. I highly recommend Everest and will be using them again (hopefully under less urgent circumstances!)Services: Plumbing leak detection“
