Assess Gaps and Joints for Caulking Needs

What happens here

Carefully examine all exterior gaps and joints around windows, doors, and siding. Look for existing cracked, missing, or compromised caulk. Pay particular attention to areas where different materials meet, like trim to siding or siding to foundation. Identify specific points such as the gap underneath a window or any exposed nail heads that could allow water penetration. Consider the purpose of the caulk – is it structural, cosmetic, or for weatherproofing? For weatherproofing, ensure all potential entry points for water, air, and pests are noted.

Goal: Begin by thoroughly inspecting the exterior of the house, focusing on areas prone to air and moisture intrusion such as gaps beneath windows, around window frames, and exposed nail heads in siding. The video shows identification of a gap under a window and an exposed nail head.
