I am very impressed with the service I received from HEP. I recently had them install a tankless water heater and relocate the hookups to my basement. This left a hole in the ceiling from the vent, some holes in the floor for the old piping, as well as an unfinished piece of flooring where the old hot water heater used to sit. The quote I received wasn't specific to either include or exclude the time of a dry waller to match the stamped patter of my ceiling surface or for someone to come out and replace a piece of subfloor AND lay new laminate flooring. I didn't have to argue. I am used to having to argue to get good service from contractors and HEP just did the work no questions asked. In addition to the plumbing work they sent out two separate service calls to fix the ceiling and the floor and the space looks like there was never a hot water heater to begin with. I'm sure that those additional trips ate into their planned budget/profit of the water heater installation but since the quote and contract weren't specific they just did the work without any push back! I will definitely be spending my money with HEP in the future because I trust that they have integrity with their work and they aren't just in it for a quick buck. They are obviously looking to build relationships for lifelong customers. I will be that lifelong customer. I already have another quote with them for another project in the works.
