Step-by-Step Guide: How to Seal Your Garage Door

Follow these easy directions to make sure your garage door is sealed well.

1. Prepare the Area

Begin by clearing any clutter or obstructions near the garage door to give yourself enough room to work. This step ensures easy access to the door frame and a smooth workflow for sealing.

2. Clean the Surfaces

Thoroughly clean the door frame and any areas where weatherstripping or seals will be applied. Use a degreaser or mild detergent to remove dirt, grease, and debris, ensuring the adhesive bonds properly for a durable seal.

3. Measure and Cut the Weatherstripping

Carefully measure the edges of your garage door frame, including the top and sides. Cut the weatherstripping to match these dimensions, leaving a small overlap at the corners to ensure complete coverage and an airtight fit.

4. Install the Weatherstripping

Apply a high-quality adhesive or weatherproof caulk to the door frame edges. Attach the weatherstripping with firm pressure, keeping it straight and properly secured. Double-check for gaps and press again if needed to create a tight seal.

5. Replace the Bottom Seal

If the bottom seal is worn or cracked, remove it by sliding it out of the track or prying it loose. Measure the width of the garage door, cut a new bottom seal to size, and fit it securely into place.

6. Seal Gaps and Cracks

Inspect the door frame and surrounding areas for any visible gaps or cracks. Use a durable caulk or sealant to fill these spaces, smoothing it out with a putty knife for a clean, polished look and a complete seal.

7. Test and Adjust
