P-Bulb Garage Door Bottom Seal

This P-bulb garage door seal replacement slides into a P-bulb-style aluminum retainer mounted along the bottom of a garage door. Designed for compatible Genie and Overhead Door models, the flexible bulb compresses against the floor when the door closes to help seal gaps that can allow drafts, moisture, dirt, and outdoor debris into the building.

Made from a strong, flexible gray vinyl compound, this P-bulb garage door seal is suitable for residential and commercial rolling steel doors. It is available by the foot for individual doors or as a bulk 100-foot reel. When ordering by the foot, enter the total footage needed in the Quantity field, and the seal will arrive as one continuous piece in the selected length.

Choosing Your Weather Seal

Manufacturer and model compatibility can help identify the correct product, but the existing retainer profile should always be confirmed because garage door components may vary.

Installation Best Practices

This Genie and Overhead Door P-bulb seal installs by sliding the attachment profile through the existing aluminum retainer at the bottom of the door. Inspect the retainer before installation because bent, damaged, corroded, or obstructed channels may prevent the new seal from sliding properly or making even contact with the floor.

• Confirm that the new P-bulb profile matches the existing retainer before removing the old seal.
• Measure the garage door rather than relying on the old seal, which may have stretched or shrunk.
• Clean dirt, rust, and debris from the retainer channel before feeding the replacement seal.
• Use a small amount of diluted dish soap in the channel if additional lubrication is needed.
• Have a second person guide longer seal lengths to make installation easier.
• Center the seal and verify even contact across the door before trimming excess material.

For additional preparation and installation guidance, review the garage door weather seal installation guide.

Compatibility Notice

Garage door designs can vary, and retainer shapes and sizes may have changed over time. Please double-check your existing retainer or track before ordering and contact us with photos or measurements if you need help choosing the right seal.
