I replaced 7 very old windows in my home, 4 basement and 3 main floor. After meeting with a few companies, I chose Ambia because I felt they would be the most reliable and provide the best quality. Tony was very professional and knowledgeable. The level of communication was excellent from beginning to end. As I wasn't home during the installation, I especially liked the fact that Tony came by later in the day to inspect the work and check in. During the installation, it was discovered that there was a space in the wall surrounding the pipe leading outside to my air conditioning unit and that air was leaking. Tony was nice enough to have his installers fill in the gap with their materials. I sincerely appreciated this gesture. Overall, I am very pleased with Ambia's service and workmanship. I would highly recommend them.
