What Should You Repair Before Installing New Siding or Windows?

Before new siding or windows go in, find and fix what's actually causing damage — active leaks, wet or decayed framing, failed flashing, and drainage problems — rather than covering it up. This guide covers what an inspection should catch, how to tell if sheathing or framing needs replacing, proper flashing and water-control details, and the right sequence for the whole project.
