Garage Door Weatherstrip - FAQs & Troubleshooting

Garage door weather seals help keep out water, dirt, drafts, insects, and debris. The correct replacement depends on the shape and size of the seal ends that slide into the bottom retainer track. Weather seals are not universal, so it is important to compare the profile of your existing seal before ordering.

How to Identify the Correct Weather Seal

Remove a small section of your current seal and look closely at the ends that slide into the track. The end shape, bead size, T-end size, and overall seal width determine compatibility.

Common Garage Door Bottom Seal Types

• 3/16" Bulb Shaped End Weatherstrip
• 1/4" T-Shaped End Weather Seal - 3 3/8" Width
• 1/4" T-Shaped End Weather Seal - 2 3/4" Width
• 3/16" Bead End Weatherstrip
• 5/16" T-Shaped End Weatherstrip

How to Measure for Replacement Weatherstrip

1. Measure the full width of the garage door.
2. Measure the flat width of the existing seal, not inflated or folded.
3. Measure the end shape that slides into the retainer track.
4. Compare the end profile to the replacement seal before ordering.

Do not rely on the garage door model number alone. Weather seals can vary even on the same door model depending on the bottom retainer installed.
