13 Easy Steps on How to Fix Gap at Bottom of Garage Door
Step 1: Inspect the Gap and the Garage Door
Begin by inspecting the gap at the bottom of your garage door to determine its size and cause. Look for any signs of damage or wear on the door, the weatherstripping, or the garage door track. Identifying the source of the gap will help you determine the appropriate solution for fixing it.
Step 2: Check the Garage Door Alignment
A misaligned garage door can cause gaps at the bottom. Use a level to check the alignment of the door and the tracks. If the door or tracks are not level, adjust them by loosening the brackets holding the tracks in place, shifting them until they are level, and then tightening the brackets.
Step 3: Inspect the Weatherstripping
The weatherstripping at the bottom of the garage door helps to create a seal and prevent gaps. Inspect the weatherstripping for wear, damage, or improper installation. If the weatherstripping is damaged or worn, it will need to be replaced to effectively seal the gap.
Step 4: Replace the Weatherstripping
To replace the weatherstripping, remove the old weatherstripping by either unscrewing it or prying it off with a flat-head screwdriver. Clean the area where the old weatherstripping was attached, then measure and cut a new piece of weatherstripping to fit the width of your garage door. Attach the new weatherstripping by either screwing it in place or using an adhesive, following the manufacturer’s instructions.
Step 5: Adjust the Garage Door Limit Switch
If the garage door is not closing fully, leaving a gap at the bottom, the limit switch may need to be adjusted. The limit switch controls how far the door travels when closing. Locate the limit switch on the garage door opener motor unit and consult your garage door opener’s user manual for instructions on how to adjust it. Make small adjustments to the limit switch until the door closes fully and eliminates the gap.
Step 6: Inspect the Garage Door Rollers
Worn or damaged garage door rollers can cause the door to sit unevenly, resulting in a gap at the bottom. Inspect the rollers for signs of wear or damage and replace any that are not functioning properly. To replace a roller, remove the bolt and nut holding the roller in place, slide the old roller out of the bracket, and insert a new roller before reattaching the bolt and nut.
Step 7: Check the Garage Door Springs
The garage door springs provide tension that helps the door close evenly. If a spring is damaged or has lost tension, it can cause a gap at the bottom of the door. Inspect the garage door springs for signs of wear or damage. If a spring needs to be replaced, it is recommended to hire a professional garage door technician, as replacing garage door springs can be dangerous if not done correctly.
Step 8: Inspect and Adjust the Garage Door Track
A misaligned garage door track can cause the door to sit unevenly and create a gap at the bottom. Inspect the track for damage or misalignment, and adjust it as necessary. To adjust the track, loosen the bolts holding it in place, gently tap the track with a rubber mallet until it is properly aligned, and then tighten the bolts.
Step 9: Test the Garage Door
After making adjustments or repairs, test the garage door to ensure that it is closing fully and that the gap at the bottom has been eliminated. Operate the door using the wall-mounted button, remote control, or keypad and observe its movement to confirm that it is closing evenly and securely.
Step 10: Perform Regular Maintenance
To prevent future gaps at the bottom of your garage door, perform regular maintenance, including inspecting the door
, weatherstripping, tracks, rollers, springs, and other components for signs of wear or damage. Lubricate moving parts, such as rollers and hinges, with a high-quality garage door lubricant to ensure smooth operation and reduce wear. Maintain proper alignment of the door and tracks by periodically checking their level and making adjustments as needed.
Step 11: Insulate the Garage Door
If you live in a region with extreme temperature fluctuations, consider insulating your garage door to help maintain a consistent temperature inside the garage and reduce the likelihood of gaps forming at the bottom. Insulation kits are available for various garage door types and can be installed following the manufacturer’s instructions.
Step 12: Install a Garage Door Threshold
A garage door threshold is a rubber or vinyl strip that is installed on the garage floor where the door closes, creating a tight seal and preventing gaps at the bottom of the door. Measure the width of your garage door opening and purchase a threshold that is the appropriate length. To install the threshold, clean the garage floor, apply adhesive according to the manufacturer’s instructions, and press the threshold into place.
Step 13: Consult a Professional
If you have attempted to fix the gap at the bottom of your garage door and are still experiencing issues, consult a professional garage door technician for assistance. They can diagnose and resolve any problems, ensuring the safe and proper operation of your garage door system.
By following these steps, you can effectively fix the gap at the bottom of your garage door, ensuring a secure and well-sealed closure. Regular maintenance and inspections will help prevent future issues, while additional measures such as insulation and the installation of a garage door threshold can further improve the seal and performance of your garage door. If you encounter any persistent or complex issues, seek the help of a professional garage door technician to ensure the safety and functionality of your garage door system.
