Comment : Nick and his team embody customer service and excel in customer recovery. We had a couple bumps along the road in replacing window screens but they were prompt and attentive taking responsibility and accountability. They were kind enough to offer consolations when things weren’t right and came to us on several occasions. I would highly recommend.

Comment : Glass top for a table. I wanted a glass top for a table with caning in the top, each corner had to be cut out to accommodate the tops of the legs. Granite State glass created the glass topper exactly with nicely polished edges that fit perfectly. Excellent craftsmanship and quick service.

Comment : GSG replaced 21 windows and an entryway last month. The products are fantastic and work better than expected. We can't say enough good things about their team members. From sales to administrative staff to installers, all were professional, timely, respectful of our home, pleasant and quiet. We would always be happy to recommend GSG. Thanks for a great product and job!!!
