The restoration of wood windows is a multi-faceted and meticulous process, as illustrated in the slideshow above.

Once the existing coatings have been removed, the windows are evaluated for condition issues. When rotten wood is present, a technique called Dutch patching is most often used to replace those sections of the sash. The new pieces are then shaped by hand to match the existing profile.

Marine-grade epoxy resin is commonly used to fill any small voids. This hardens the existing wood, which is typically old growth pine.

Once the sashes are restored, the finishing process can begin. Typically, sashes are primed before receiving two coats of premium quality paint. Otherwise, they are stained and finished with several coats of clear polyurethane.
