A Step-by-Step Guide for Replacing Weatherstripping on Your Garage Door

Maintaining your garage door’s weatherstripping is essential for keeping your garage well-insulated. It protects your door and garage from the elements. Over time, weatherstripping can become worn or damaged. This will lead to drafts, pests, and decreased energy efficiency. Replacing it is a straightforward DIY task that can have a significant impact on your garage’s comfort and energy usage. If this seems like too much, that’s okay! You can always contact a professional who will be happy to help. Here’s a step-by-step guide to help you through the replacement process:

Step 1: Gather Your Supplies

Before you begin, make sure you have all the necessary tools and materials:

  1. Choose a weather-resistant material that suits your climate and garage door type (vinyl, rubber, or silicone).
  2. Measuring tape
  3. Utility knife or scissors
  4. Screwdriver or drill to remove old weatherstripping.
  5. Cleaning supplies: Mild soap, water, and a rag
  6. Weatherstripping adhesive

Step 2: Measure and Assess the Current Weatherstripping

Close the garage door and inspect the existing weatherstripping. Note its condition and measure the length you’ll need to replace. Measure the top, sides, and bottom of the door, adding a few inches to each measurement to ensure a snug fit.

Step 3: Remove the Old Weatherstripping

If the old weatherstripping is damaged or worn, you’ll need to remove it. Carefully peel it away from the door frame. Depending on the type of weatherstripping, you might need to unscrew or unclip it using a screwdriver or drill. Be gentle to avoid damaging the door frame.

Step 4: Clean the Surface of Old Adhesive and Grime

Before installing the new weatherstripping, clean the door frame surface. Anywhere the new weatherstripping will adhere should be clean of dirt. Use a mild soap and water solution to remove dirt, debris, and any adhesive residue from the previous weatherstripping.

Step 5: Cut the New Weatherstripping to The Right Measurements

Using the measurements you took in Step 2, cut the new weatherstripping to the appropriate lengths. Use a utility knife or scissors, making clean and straight cuts. You can also ask for your weatherstripping to come precut if you already have the measurements when making the purchase.

Step 6: Start with the Top of Your Garage Door

Begin the installation process by attaching the new weatherstripping to the top of the garage door frame. Apply weatherstripping adhesive along the back of the weatherstripping or use nails to secure it in place. Press the weatherstripping firmly against the door frame, ensuring a snug fit.

Step 7: Do the Sides of Your Garage Door Next

Next, move on to the sides of the door frame. Apply the weatherstripping adhesive or use nails to secure the weatherstripping along the sides. Make sure it aligns properly with the top piece and extends down to the bottom of the door frame.

Step 8: Install the Bottom Weatherstripping

For the bottom of the garage door, you’ll need a different type of weatherstripping designed to seal against the floor. This might be a U-shaped or T-shaped piece. Slide or press the bottom weatherstripping into place, ensuring it forms a tight seal when the door is closed.

Step 9: Open and Close the Door to Test It

After installing all the new weatherstripping, open and close the garage door a few times. This way you can ensure that it moves smoothly without any obstruction from the new weatherstripping. Check for any gaps or areas where the seal might not be tight.

Step 10: Make Necessary Adjustments

If you find any gaps or areas where the seal isn’t tight, make the necessary adjustments. You might need to trim or reposition the weatherstripping to achieve a proper seal all around the door.

Perform a Final Check Before Walking Away

Once you’re satisfied with the installation and the door moves smoothly, do a final inspection. You need to ensure that the weatherstripping is securely attached and forms a consistent seal.

You Now Have a Properly Sealing Garage Door Again

By following these steps, you can successfully replace the weatherstripping on your garage door. This relatively simple DIY project can greatly improve your garage’s insulation and comfort. A great seal also will help you keep pests and the elements at bay.
