About this product
Sliding Glass Doors for Exeter homes
Old sliders are one of the biggest air-leak points in a New England home: the rollers wear, the panel drops, and the weatherstripping stops making contact. We replace the complete unit — frame, sill, panels, and hardware — with an insulated glass sliding door built for wind-driven rain and salt air. Low-E insulated glass, a multi-point locking system, and heavy-duty rollers on a corrosion-resistant track keep the panel gliding and the seal tight.
- ✓Full-frame replacement, not a panel swap
- ✓Low-E insulated glass
- ✓Corrosion-resistant track and heavy-duty rollers
- ✓Multi-point locking hardware
- ✓Interlocking weatherstripping at the meeting stile
- ✓Installed by W-2 crews with a limited lifetime warranty

Cost
How much does Sliding Glass Doors cost in Exeter, NH?
Sliding-door pricing depends on the width and number of panels, the glass package you choose, the hardware, and what we find when the old unit comes out. Rotted sills, out-of-square openings, and headers that have settled all add labor. We measure on site and quote the complete installed unit, including any framing repair we can see up front.
