Thank you for a job well done. I am very happy with my new bathroom. A special thank you to Glen Krewet for his kindness and patience in explaining everything. And a very special thank you to Ruben, he is such a hard worker and does such a beautiful job. I will sure recommend your company to others.

Glen and his crew at P. S. Rapp have always been professional and pleasant when performing any service in my home. He gives fair quotes and even comes in under the quotes. As a plumber, they could take you for your money, but Glen will actually take the time to explain what services were performed, Glen returns phone calls in a timely fashion, even if you have the simplest of questions or even at the most inconvenient of tlmes. His quick response time and knowledge of his field is unbeatable. I would trust P.S. Rapp with all my family, friends, and clients.
