How to seal garage door bottom?
To provide a more detailed guide on sealing the garage door bottom, follow these steps:
Step 1: Assess the current state of your garage door bottom seal
Inspect your garage door bottom seal to determine if it is damaged, worn out, or improperly installed. If these issues are present, it’s time to replace or repair the seal.
Step 2: Choose the appropriate type of garage door bottom seal
There are several types of garage door bottom seals available, including:
- T-style (T-end or T-bulb): This seal has a T-shaped rubber or vinyl part that slides into a track on the bottom of the door.
- J-style (Bead end): This seal has a round bead that fits into a J-shaped track on the bottom of the door.
- Bulb seals: These seals have a round or oval-shaped bulb that compresses against the ground when the door is closed, creating an airtight seal.
- Threshold seals: This are rubber or vinyl strips installed on the garage floor, providing a seal when the door closes on top of them.
Choose the type of seal that best suits your garage door and the specific conditions in your area.
Step 3: Measure and cut the new seal
Measure the width of your garage door and cut the new seal to the correct length, leaving about an extra inch on each side to ensure a proper fit.
Step 4: Remove the old garage door bottom seal
Lift the garage door to about six feet high. If your garage door has a track, carefully pull the old seal out through the gap behind the door track.
If your seal is attached directly to the door, remove any screws, nails, or adhesive holding the seal in place.
Step 5: Install the new garage door bottom seal
For T-style or J-style seals, slide the new seal into the track on the bottom of the door, starting from one end and working your way across.
If the seal is difficult to slide, apply soapy water or silicone spray to help it glide more easily.
For bulb seals, attach the seal directly to the bottom of the door using screws, nails, or adhesive, depending on the manufacturer’s recommendations.
For threshold seals, clean the garage floor where the seal will be installed and apply a strong adhesive to the bottom of the seal. Position the seal on the floor, ensuring it is centered and straight, and press it firmly into place.
Step 6: Test the effectiveness of the new seal
Close the garage door and check for any gaps or air leaks along the bottom. Make any necessary adjustments to ensure a tight seal, such as trimming excess material or repositioning the seal.
Following these detailed steps, you can effectively seal the bottom of your garage door, keeping out drafts, dust, and pests.
