These guys not only showed up when they said they would, they did an AMAZING job replacing broken aged pipes, replacing damaged subfloor, installing new pipes under the bathroom sink into the basement, and replaced my kitchen faucet. I don't know that I've met someone with the passion behind their mission like Rotterdam Renovations. We need more contractors like this in rotterdam!"

"Mike McGovern and his son Brian installed a Navian NPE-240S2 tankless water heater and removed the old 50 gallon tank. The installation required new vent piping. Mike considered several options for routing the pipes and made an extraordinary effort to implement the venting with a maximum of six elbows as specified by the manufacturer to assure adequate venting, away from windows, while still providing protection against rain. It has now been seven weeks and the new installation has performed flawlessly. I could not be more pleased with the work."

"We had no water and thought we had frozen pipes. They came within 2 hours on a Sunday. Checked out the situation and said it was the well pump the pipes were not frozen. He was very helpful trying to get someone for us... Will be calling him for other plumbing problems.. We would recommend them...."

"Very prompt. We blew our hot water heater overnight. I found "A" Real Plumber with Home Advisor. He was at the house at noon and done by 1:30 as he said he would. Replaced the hot water heater at a very reasonable price and removed the old one. Great personality and a pleasure to be around. Winston and his son Justin are now our go to Plumbers. Thanks Winston and Justin."
