"I needed an 18yr tankless hot water heater removed and a new one installed. Mike and Brian came over and swapped it out with ease. Looks nice and neat and they took time to explain what they did and what to expect. I have rental property and Mike will be the 1st person I call in the future. 5-Stars all the way!"

"Best call I've made. 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!"

"Robert came out right away and gave me a quote to buy and install a new tankless hot water heater. His price was FAR better than the other quotes that I received for the same heater. He agreed to come out and install it right away and did a great job. No mess, no hassle.. He was willing to answer all my questions and make sure everything was satisfactory before he left. I will use him for ALL future plumbing projects that come up in the future!"

"I recently hired Joe to install my new gas cooktop, and I could not be more pleased. Not only did he do a fantastic, clean job with the gas line and appliance installation, but he also handled the necessary extra electrical work to connect it. He was knowledgeable, efficient, and ensured everything was up to code and working perfectly. Highly recommend!"
