Cracks and gaps on the outside of your home cause air infiltration that increases the heating and cooling cost of your home as well as wasting energy. Since approximately one-third of a home’s air infiltration comes from small openings in walls, windows, ceilings, and doors; it’s important to locate and properly seal these gaps.
To caulk cracks on the outside of your home:
- Use a putty knife to scrape out any old caulk from the opening.
- Wipe off the crack with a rag to remove any dust.
- Apply a bead of quality exterior caulk to fill the gap.
- Smooth the bead of caulk with your finger, removing any excess caulk.
