- Check with your town's planning department to learn of any code requirements.
- Obtain any necessary permits from the planning department.
- Check with local building suppliers and home improvement stores to learn if there's a retrofit kit made for your garage door.
- Purchase the appropriate kit, if available. Your kit will include manufacturer's specific instructions.
- Install horizontal bracing onto each garage door panel.
- Install heavier hinges using heavy duty screws or bolts (as provided in the kit).
- Install stronger center supports and end supports.
- Check the track on the garage door. Using both hands, grab a section of each track, then attempt to pull and twist it. If it loosens or twists, you need to install a stronger track.
- Install the new track, carefully anchoring it to the 2x4s inside the wall with heavy wood bolts, or in a brick home, attach to the masonry with expansion bolts.
- After completing the retrofit, check the door's balance. Lower the door half way, then let go. If it moves up or down, the springs need adjusting. Spring adjustment requires a professional.
