The sales person was very friendly, and did not try to over-sell his products to us. He asked for our budget and gave us a list of products that would fit our needs. The job was scheduled quickly, and the crew installed all 11 windows in one day. The windows look great and our house is much more efficient.

I was very impressed with Gravinas from beginning to end. The window installation team was fabulous. They were extremely professional, respectful and clean.

Anybody can buy materials and dump them on your front lawn. But Gravina’s is superior in all aspects of the process. From sales to installation to customer service- Gravina’s vastly exceeded my expectations and delivered as promised on the first go-round. Everything was right the first time and my wife and I now enjoy our “ne” home, quieter, more energy efficient, and extremely comfortable. We are very satisfied and would recommend Gravina’s to everyone!

We bought our windows from Gravina’s because they had been referred to us by family and friends who raved about them. We are delighted with our new windows! Their prices were more than competitive and their selection was unbeatable. Who wants to drive around looking everywhere when you can make one-stop and accomplish the same thing! The house is now tightly sealed and amazingly comfortable! I would wholeheartedly recommend Gravina’s Windows & Siding to anyone in the market.
