“We were extremely pleased with our experience with Window Works. There was no pressure during the estimate process. My wife and I went to the showroom to look at a sliding door the day after our estimate, and everyone we met there was very nice and answered all of our questions. The install took two days and the guys that were here were great! They respected our home and cleaned up everything as if they were never here, and did a very professional job. Overall the whole process, from estimate to install, felt like we were dealing with longtime friends. I will be contacting them with any future work. Thank you Window Works, keep doing what you are doing!”
