Step-by-Step Processes for How to Weatherproof a Garage Door

Step 1: Inspect the Garage Door

Before you begin the weatherproofing process, it is important to inspect the garage door and make sure there are no cracks, gaps, or other areas of concern. Make sure all hardware is securely fastened and properly aligned.

Step 2: Clean up the Garage Door

When weatherproofing your garage door, you want to make sure that the surface is as clean as possible. Use a garden hose and mild detergent to wash away any dirt or debris from the door.

Step 3: Add Insulation

Add insulation to the door to keep the air inside your garage warm and comfortable. Use high-grade insulating tape and carefully apply it around all edges of the door. To prevent drafts from coming through the garage door, use weather stripping to fill in any gaps between the door and its frame.

Step 4: Apply a Silicone based Sealant

To further enhance water resistance, apply a silicone-based sealant to all areas of the garage door. Allow sufficient time for this product to dry before continuing on. To prevent small critters and bugs from entering your garage, install door sweeps along the bottom of the door.

Step 5: Apply a Clear Sealant

After you have finished with the weatherproofing process, apply a clear sealant to all areas of the garage door. This will help to protect the surface from any wear and tear that may occur over time.
