"This was the second time we used H L Bowman for our plumbing needs and we have been impressed both times. Their plumbers are prompt, courteous, and friendly, in addition to being great at their craft. For this visit, I had a leak under a kitchen sink and did not realize that I needed to have the entire faucet replaced. The plumber recommended the closest plumbing supply store and waited while I selected the one I wanted. He efficiently did the replacement. Very happy with H L Bowman and would highly recommend them."
