To keep out water, air, dust, and insects
Once a year
- Walk around the house and inspect each caulking joint at the window and door frames, between two different siding materials (like brick or stucco), or around piping that enters the home.
- Confirm that caulked joints are still properly sealed and haven’t cracked, pulled apart, or fallen out. Original caulking will shrink and crack over time due to normal weathering.
- If necessary, clean the old joint out with warm soapy water and a toothbrush and reapply the same caulking material to achieve a proper seal.
- Consult with your local hardware store to select the right type of caulk.
