Paramount Plumbing, Heating, & Air Conditioning has been very thorough with their work. They have a program of checking on all of our plumbing needs periodically to suggest what can be done, which has been very helpful. They came out last time due to a generator check. The generator people said the exhaust pipe from the hot water heater was too close, causing issues because of the vent. I let the Paramount crew know about the vent, and they came right out to take care of the issue. They rerouted the vent and exhaust so it would no longer cause a problem with the generator, which was good. The workers were great! They were friendly, very professional, and they really knew what they were doing. I've been with Paramount Plumbing for about a year now, ever since they installed my tankless hot water heater, and I will continue to use them. In fact, I'm planning on them coming out again to replace a spigot that's been eroding. I am very happy with them!
