Do You Take Out All Of The External Window Caulk Prior?

To remove old caulk from windows, wait for a day with mild weather and low humidity, especially if caulking the exteriors of your windows. The weather should be at least 45℉ and free from rain for at least 24 hours. Choose the right type of caulk for your specific situation, such as exterior windows, which are impervious to hars. Cut out the compromised caulk and clean the surrounding areas with denatured alcohol. Apply fresh caulk, forming it into place to match existing caulk. For longevity and resiliency, use 100 silicone caulking.

Home improvement expert Ron Hazelton demonstrates how to remove old caulk from around outdoor window and door frames and replace it with new caulk.

Clean the surface before applying caulk, using a brush or putty knife to remove dirt, dust, and moisture.

To protect the home’s construction materials, remove caulk before caulking doors and windows and starting over.

Ideally, remove all old caulk and replace with new caulk before applying a new sealant to your home or condo.
