Using Wm. Henderson Plumbing, Heating & Cooling Inc. to replace our hot water heater was an easy decision. They've done stuff for us before and I know I can rely on their expertise. The plumbers who did the installation were nice guys. They laid down tarps in the area to keep things clean. There's not a lot of room to maneuver in the basement, but they were able to get the job done very quickly in spite of the obstacles. In the meantime, they didn't bother us at all. We just went about our business as usual (except for not using the water, of course). The guys were sociable but focused primarily on getting the job done. We'll continue using Wm. Henderson Plumbing, Heating & Cooling Inc. I even use Henderson's son, who lives up the street, to take care of fertilizing my lawn. Highly recommended to everyone.
