Mike M.
I was impressed with the Customer Service I received as I walked into the office. I was greeted by Mike Gravina, he made us feel comfortable as he was prompt and very knowledgeable in the products he showed us. I am very happy with the cost and efficiency of my windows.
Pete C.
The staff at Gravina's helped me with a remodel project. The suggestions they made were specific to my needs and I'm very happy with the finished product. They worked within the timeframe that I had and completed the work on time I will definitely use them on future projects and would highly recommend them to others.

Review in Aurora, CO
Areas Of Satisfaction
Areas Of Satisfaction - It was a good experience all around. Sales person and installer were both friendly and we didn't have any issues at all. Although expensive for the two odd shaped windows we got, we can really feel the difference in the reduction of heat that passes through. Glad to have the UV protection too.

Every aspect of the project went according to plan. One installer, Mung, completed the install of 15 windows in 2 days. Amazing! Every day I realize how much I like my new windows.
