Andersen Patio Door Restoration in Carle Place, NY

We recently completed an Andersen patio door restoration in Carle Place, NY, where the bottom panels of a beautiful French-style patio door had suffered extensive rot, peeling paint, and structural damage. The original wood cladding was saturated, soft in spots, and separating from the frame — issues that often begin subtly but progress quickly when moisture gets trapped at the base. At Prestige Window Works, we specialize in restoring Andersen patio doors, and this project was a perfect example of what precise craftsmanship can achieve.

The first thing we did was remove all the damaged trim boards. The lower panels on both doors were beyond salvageable, showing visible rot and delamination. Once stripped down, we examined the structural core and confirmed it was intact — a key factor in deciding to restore rather than replace. We cleaned the affected areas, treated the remaining wood with a hardener to prevent future decay, and prepped the frame for custom-fitted replacement panels.

For this Carle Place restoration, we milled solid PVC-reinforced lower panels to match the Andersen design and profile. These composite panels are resistant to rot, splitting, and insect damage. We sealed all edges, installed the panels with waterproof adhesive and stainless fasteners, and applied flexible, paintable exterior caulk to create a seamless barrier. The restoration process wasn’t just cosmetic — it re-established the structural integrity of the door base and made it weather-ready.

Take a look at the before-and-after image, and the difference speaks for itself. The worn, flaking wood on this Andersen patio door was not just an eyesore — it was actively deteriorating. After restoration, the door now features crisp, clean lines, a sealed bottom edge, and renewed curb appeal. This Carle Place homeowner was thrilled they didn’t need to replace the entire door to get it back to top condition.

While we were on site, we also checked the door’s rollers, adjusted the latch alignment, and inspected the threshold for soft spots. These are all part of our comprehensive patio door services, which we regularly provide in Carle Place, nearby New Rochelle, and across Long Island. We also offer sill replacements, glass repair, weatherstripping upgrades, and full wood rot restorations for Andersen doors and windows.
