If your trim boards, soffits, or window frames are bending and warping, you need to replace exterior trim. Fixings such as these protect your home from moisture and the elements. They are subsequently integral to your property’s structural integrity.
Hire a general contractor to inspect your exterior trim. He or she can decide what to do. Some of it may be salvageable, while some may need to be replaced entirely. Better to have a professional make the call.
