TL;DR
A bottom seal is the replaceable weatherstrip along the underside of a garage door that conforms to the floor when the door closes, excluding rain, drafts, dust, snow melt, and pests from the garage. Most sectional doors carry a U- or T-shaped vinyl strip in an aluminum retainer, while one-piece doors may use a nail-on flap, and uneven slabs are handled with taller bulb profiles or a threshold ramp glued to the floor.
What it means
A bottom seal is the replaceable weatherstrip along the underside of a garage door that conforms to the floor when the door closes, excluding rain, drafts, dust, snow melt, and pests from the garage. Most sectional doors carry a U- or T-shaped vinyl strip in an aluminum retainer, while one-piece doors may use a nail-on flap, and uneven slabs are handled with taller bulb profiles or a threshold ramp glued to the floor. Sunlight and freeze cycles harden the material in 5 to 10 years. It is the cheap fix homeowners try first when leaves and water keep appearing inside the door line.
