"I would highly recommend this company. I need a hose bib replaced due to leaking and they responded and completed the repair within a few hours of my contacting them. The two service techs were very professional, knowledgeable and friendly. They did an excellent job with my repairs."

"We weren't sure where the tank was, and there was some trouble finding it. Green's recommended a plumber to send a camera through. (They were prompt and professional) Green's came out again and did a fast, efficient job. (The tank was partially under a few pavers, which caused the confusion)."

"I awoke to NO water in my house. After checking everything I knew to check, I looked at the list of plumbers and decided to put in an emergency call to Glenn Tatum Plumbing.
The responded quickly to my home in North Lake County, diagnosed the problem, got parts and repaired the problem. Chris and Glenn were responsive, knowledgeable, and quick to take care of my emergency call. thank you.
I will use them anytime a problem arises and I will also refer them to my friends.

"After the tankless hot water heater was installed it was throttling the temperature. I called the team and they came out to explain this particular module they installed was ‘demand based’. It required I set the shower to a very warm temperature to engage the water heater or else it would turn off. Seemed strange and untrue since the sinks which have significantly less demand don’t experience this issue no matter how low I turn the temperature. The specialist also suggested it could be my brand new shower head since new hardware can often be low flow. Mine was not but he insisted on removing the gasket for the shower head. Now it leaks and the water still gets cold unless set to very hot. Disappointed."
