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.

Found mouse urine and droppings behind the bathroom walls. I tore out drywall and insulation saturated with urine. Added bleach then vinegar and then lavender oil. Found gap 2” x 12” . Do I close the gap with wood from inside or outside? Do I chaulk where siding meets foundation on outside? All these years I smelled urine but I would just scrub the toilet with Clorox . I also blamed the cats. MF mice ?. Help
