Inspect exterior caulk and seals
Look around windows, doors, vents, and utility penetrations.
Why it matters
Failed sealant can allow water and outside air into the building envelope.
Steps
- Walk the exterior and photograph cracked, missing, or separated caulk.
- Pay attention to the tops and sides of openings and penetrations.
- Use a compatible exterior sealant for small accessible gaps.
- Call a qualified contractor if damage extends into siding or framing.
