Tim Hance with All Islands Home Inspections recently discovered completely deteriorated trim, with the real possibility of underlying structural damage, at a recent home inspection in Mount Vernon, WA. Keeping your exterior elements properly sealed (e.g., painted and caulked) will prevent deterioration. It’s all about protecting your home from the elements! When deterioration is discovered, it should be repaired and replaced as necessary, and then painted and caulked. The longer one waits, the more expensive the issue becomes.
