Caulking garage door windows is an essential maintenance task that helps prevent air and water leaks, improves energy efficiency, and enhances the overall appearance of your garage

In this blog post, we will provide you with a step-by-step guide on how to caulk garage door windows effectively, ensuring a weatherproof seal and protecting your garage from the elements.

• Gather the Necessary Materials: Before starting the caulking process, gather all the necessary materials. You will need a caulk gun, high-quality exterior-grade silicone caulk, a putty knife or caulk smoothing tool, a utility knife, and a clean cloth. Ensure that the caulk you choose is compatible with both the window material and the exterior surface of your garage door.
• Prepare the Windows: Begin by thoroughly cleaning the window frames and glass using a mild detergent or glass cleaner. Remove any dirt, dust, or old caulk residue. Use a utility knife to carefully scrape away any loose or peeling caulk. Wipe the windows dry with a clean cloth to ensure a clean surface for the caulk to adhere to.
• Apply the Caulk: Load the silicone caulk into the caulk gun and cut the tip of the caulk tube at a 45-degree angle. Start at one corner of the window and apply a continuous bead of caulk along the seam between the window frame and the garage door. Hold the caulk gun at a 45-degree angle and apply steady pressure to ensure a consistent bead. Move along the entire perimeter of the window, applying the caulk in a smooth and controlled manner.
• Smooth and Shape the Caulk: Using a putty knife or a caulk smoothing tool, gently smooth the caulk bead to create an even and seamless seal. This step helps ensure proper adhesion and improves the overall appearance of the caulk line. Wipe away any excess caulk with a clean cloth or damp sponge before it dries.
• Allow the Caulk to Cure: Follow the manufacturer’s instructions for the recommended drying time of the caulk. It typically takes 24 to 48 hours for silicone caulk to fully cure. During this time, avoid touching or disturbing the caulked areas to allow for optimal adhesion and performance. Keep the garage door closed during the curing process to maintain a stable environment and prevent exposure to moisture.
