Insulated sliding patio doors that stay sealed through coastal winters.







About this product
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.
Our process
Free in-home consultation and exact opening measurement
Panel configuration, glass, grid, and hardware selection
Custom manufacture of the door and frame to your opening
Removal of the old unit and inspection of the sill, header, and framing
Install of the new unit: leveling, shimming, insulation, flashing, and sill pan
Hardware adjustment, cleanup, walkthrough, and warranty registration

Cost
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.
