I have an area(approximately 16 X 4) of Masonite siding that it is soft from some moisture. The area is at the bottom of the siding above my patio. Removing the siding and replacing is an undertaking because I have a wooden pergola that has a ledger board that is affixed to the side of the house at the top of the affected piece.
My question is, is there a way that I can cut out the soft area and fill it in with something? Much like spackling on drywall? The reason that this comes to mind, is because on another area of the home with siding, there appears to have been something like this done. The texture is different but that is o.k. If the siding is cut out and there is something like spackling that I can use, what needs behind the area that is void for the spackling to affix to?
