I had a very good experience with Renaissance Windows and Doors. The salesman, Derrick, was very knowledgeable and answered all of my questions. He was very professional and most of all, not a high pressure salesman! His attitude and the beautiful Marvin fiberglass windows made my decision for me. The installer, Phillip and his helper Kevin (?) were very good. Clean work, no glass and minimal dust left to clean up after they were gone. Good job!
