Even on newer construction projects, if not done properly, repairs will shortly be needed. This was the case with the lower portions of these bay windows. After removing the damaged wood, we replaced it with an all vinyl solid material. Now it should be maintenance free into the foreseeable future. It also does not need to be painted. If you newer home that is in need of repairs due to shoddy workmanship or materials call Drumm Design Remodel for Handcrafted Quality you can trust at 215-699-7477.
