If your window frame is bent, cracked, or damaged, it will need immediate repair. A damaged frame can cause water damage inside your sunroom’s windows as well as provide an access point for pests and bugs. Repair and maintenance of your sunroom’s frame is dependent upon the frame material. Wood frames should be regularly stained or painted to refrain from splintering and breaking. If a portion of the wood frame is cracked or damaged, then that section should be replaced completely. Vinyl and aluminum frames require less regular maintenance than wood. However, if your vinyl or aluminum frame is bent or damaged, then it should be replaced immediately.
