Marvin Wood Window Restoration in Purchase, CT

We recently completed a Marvin wood window restoration project in Purchase, CT, where the lower sill had suffered extensive rot, paint failure, and water intrusion. These windows are known for their precision-crafted joinery and beautiful wood interiors, but when left exposed to moisture without sealing, even a premium Marvin unit can break down. At Prestige Window and Door Repair, we understand how to restore these high-quality windows without compromising their original architecture.

In this Purchase home, the lower window sill and interior stop rail had completely deteriorated. Flaking paint, moisture-stained wood, and soft, rotted edges made the sash loose and hard to operate. We began by removing the window hardware, lifting the sash, and carefully removing all compromised wood along the sill and apron. One of the challenges with Marvin windows is matching their profile cuts and sash dimensions exactly — there’s no room for guesswork when the window frame has to be fully resealed.

After cleaning and treating the surrounding frame with wood stabilizer, we custom-milled new sill boards using exterior-grade pine that matched Marvin’s original dimensions. We installed the new boards with waterproof wood adhesive and stainless steel fasteners, then reset the weatherstrip and sash hardware. Once the rebuild was complete, we primed and prepped the repair for painting. The glazing bead and lock were cleaned and tested for alignment, ensuring a seamless function.

The before-and-after transformation made a big impression. The original sill in this Purchase home was soft, cracked, and filled with debris. The rebuilt version is clean, structurally sound, and ready for decades of performance. This homeowner was relieved we didn’t need to replace the entire window — especially with Marvin’s higher-tier units. The final product blended into the rest of the window system without disrupting its symmetry or style.

While we were there, we also inspected nearby Marvin windows and completed minor rot repairs and sash lubrication.
