DIY steps

- Remove the old weatherseal strip from the garage door, taking note of its position and any retaining clips or screws that held it in place. If the old strip is stuck, use a hacksaw to carefully cut it into manageable sections for removal.
- Clean the area where the new weatherseal strip will be installed, removing any dirt, grime, or old adhesive. This will ensure a secure bond between the new strip and the garage door.
- Cut the new weatherseal strip to the correct length using a hacksaw, leaving a little extra material at each end for a snug fit. Install the new strip, ensuring it is properly seated in any retaining clips or screws.
- Secure the new weatherseal strip in place using the provided screws or nails, making sure they are tightened firmly but not over-tightened. Check the strip for any gaps or unevenness, adjusting as necessary.
- Test the garage door's seal by closing it and checking for any gaps or air leaks around the edges. Make any necessary adjustments to the weatherseal strip to achieve a tight seal.
