"Got the whole package for LESS than the price of JUST the roof quoted from another company. We loved their competitive pricing. Roof looks great. Installs were scheduled quickly. An energy audit was included and qualified us for extra rebates! Bonus! Happy customer!"

"I had a flood starting in my basement when my sump pump went out. Luckily, when I called Paul (of PP's Plumbing) he was able to come right over and swap it out before the water really became a problem. He was fast, efficient and fair. I would trust all of my plumbing to Paul."

"I specified that it was a tankless water heater, yet not surprisingly I was referred to a plumber who didn't know anything about tankless heaters, resulting in a waste of a couple of days. The second person did know about them, and so far the repair is working (fingers crossed). I wish CHW would pay attention to the details in my claim."
