Recaulking home residential windows is a straightforward DIY task that can improve energy efficiency. Start by removing old, damaged caulk using a putty knife or caulk removal tool. Clean the area thoroughly with a wire brush and rubbing alcohol to remove debris and ensure proper adhesion https://kettlecontracting.com/ . Next, apply painter’s tape along the edges of the window frame to create clean lines. Choose a high-quality caulk suitable for your climate—silicone is best for durability, while latex is easier to paint over. Cut the caulk tube tip at a 45-degree angle and apply steady pressure to create a smooth bead. Use a caulk-smoothing tool or your finger to ensure a tight seal. Allow the caulk to dry completely before removing the tape and testing for drafts.
