Wonderful service, great windows and follow up. Quick, efficient and thorough. Very pleased!

Kenneth W.

Exceptionally long wait time on manufacturer. My only complaint. My windows were 60 yrs. old steel frame single pane glass in brick home. A real pain to demo. They handled it very well and did very little damage. No broken brick no broken tile on sills. Minor scuffs on exterior soffit. New windows were installed very efficiently and sealed expertly all the way around with foam and and excellent job of caulking inside and out. You can ruin a good installation with a bad caulking job. Windows look great and the house is much quieter. Looking forward to the difference this winter in my heating costs. Brian & James were our installers. Very clean and respectful and on time every day. I watched every step in the demo and installation and I'm very happy with the whole process other then the manufacturing delay. Great company for new windows.

Our experience with Gravina's was first class in all areas from the sales force to the installers! The sales staff really listened to what we wanted and gave us exactly what we asked for - NO PRESSURE here. A very comfortable experience.
The installers were very professional, friendly, fast and helpful.
They left our home just like it was before they came, except that now there are beautiful easy to operate and clean, brand new WINDOWS!!
Thank You Gravina's!!
