I love my new windows!




I heard about Gravina's from a friend and of course also heard their ads on the radio. I live in Boulder, which is quite a distance from Gravina's showroom but I wanted to visit them to actually see the different types of windows. Larry Gravina kindly agreed to meet me on a Saturday morning and we went over all the types of windows that would fit my needs and budget. Larry was very patient and answered all my questions. We decided on Alside windows. The windows arrived in a few weeks and the installation only took two days. The installers were great and were very careful not dirty up my home. Gravina's was great to work with and I highly recommend them to anyone looking for replacement windows.
