Fixing Rot on Wooden Windows
In some cases, the best solution may be to cut out the damaged section of wood, carefully cut a replacement of piece pressure-treated wood to the same shape and dimensions, and glue the piece into the window casing with a high-quality, exterior-grade adhesive that accepts paint. Solid PVC stock is an even more durable material than PT wood, although it can be difficult to find in some areas.
We’ve found that an oscillating multi-tool equipped with a plunge blade is an excellent device for cutting out the problem area. Remove all loose wood, dust and debris. We also recommend coating all sides of the replacement piece—plus the damaged area—with exterior primer before fastening in place, to add an extra measure of moisture protection. After gluing and nailing or screwing in the replacement piece, fill the seams with exterior-grade wood putty and sand the joints smooth. Apply paint-able waterproof sealant, primer and matching paint to complete the repair. Visit www.extremehowto.com.
