Shop replacement garage door bottom seals for residential, commercial, and industrial sectional doors. Bottom seals install along the lower edge of the garage door to help close the gap between the door and the floor.

A properly fitted bottom seal helps reduce the entry of rain, wind, dust, leaves, insects, and outside air. It can also help cushion the door as it closes and improve contact across uneven or slightly worn garage floors.

This collection includes multiple garage door seal styles and profiles, including:

  • Astragal bottom seals
  • Open-face bottom seals
  • Single-T seals
  • Tongue-and-groove seals
  • Shiplap seals
  • Long-leg bottom seals
  • Hard-rubber seals
  • Soft-foam seals
  • Bottom bead seals
  • Universal bottom seals
  • Residential and commercial seal profiles

Garage door bottom seals are not universally interchangeable. The correct replacement depends on the shape and size of the existing seal, the bottom retainer or door section, the required width, and the garage door manufacturer or construction style.

Before ordering, remove or inspect a small section of the existing seal and compare:

  • Seal profile and shape
  • Width when laid flat
  • T-end, bead, or attachment dimensions
  • Number of retaining channels
  • Existing aluminum or plastic retainer
  • Garage door thickness and construction
  • Required finished length

The listed seal width usually refers to the material laid flat and may not equal the final height or loop size after installation.

Some bottom seals are supplied in rolls or cut lengths. Retainers, fasteners, lubricants, adhesives, and installation tools are not included unless specifically shown or stated on the individual product page.

For easier installation, clean the retainer channels and remove dirt, corrosion, and damaged seal material before inserting the replacement. A compatible lubricant may help the seal slide through long retainers. Avoid stretching the seal during installation because it may shrink back after it is released.

Replace the bottom seal when it becomes cracked, hardened, flattened, torn, brittle, or unable to maintain consistent contact with the floor.
