The material matters as much as the shape when the garage sees real winters. Vinyl is the common choice: it resists moisture and sun well but grows stiff in deep cold and stops moulding itself to the concrete. Rubber stays supple at low temperatures and follows an uneven floor, though it can harden after many years of sun. Silicone keeps its flexibility through hot and cold alike and resists cracking, at a higher cost per metre. Choosing the right compound for a door that faces the weather is part of the service, and it is one reason a replacement seal often outlasts the one it replaces.

Garage Door Bottom Seal Replacement · Chedoke Park

Scene 1
Before the old seal comes off, the technician watches the door close under power. Where the door stops, how firmly it lands, and whether the bottom section flexes as it settles all show how the down limit and force are set. A door that stops short leaves a gap regardless of the seal; one set to press hard flattens a new seal in a season and can bow the section. The current settings are noted so they can be reset once the new, taller strip is in place, and the photo eyes and reversing behaviour are checked at the same time so the finished door is tested against a known starting point.
Scene 2
Where the slab slopes toward the garage or has a dished edge, a threshold seal glued to the floor follows the existing contour and gives the bottom strip a raised, consistent edge to meet, rather than levelling the floor itself. The floor line is marked with the door closed, the concrete is swept and cleaned for the adhesive, and the threshold is dry-fitted and trimmed against each jamb. Adhesive is laid along the underside, the threshold pressed down, and the door lowered onto it while it sets. The result is a small raised lip on the outside that turns water back to the driveway and a bottom seal that lands on a consistent edge along its length.
Scene 3
Once a season, close the door, turn off the lights and look along the floor. You are checking for a line of daylight, a corner where the seal hovers, an end that has slipped from its channel, and cracks along the fold of the bulb. Run a hand along the strip for stiff or brittle patches. Then watch the door close under power once and notice how it lands. A change in any of these is worth a call while the fix is a seal or an adjustment rather than a torn strip dragged through a winter. The check takes less time than reading this paragraph.

Two causes are common. The door may be hanging out of level because a lift cable has stretched, a drum has crept on its shaft or spring tension is uneven, which drops one corner. Or the slab may have settled or heaved at that end so the floor falls away. The technician checks both before choosing a seal, since a level door and the right seal height together close a wedge-shaped gap.
A threshold seal is a rubber or aluminum-backed strip glued to the garage floor along the line where the door closes. The door's bottom seal lands on it, and its raised outer edge turns water, wind-blown debris and small visitors back toward the driveway. It earns its place where the drive slopes toward the garage, the slab sits below the apron, or the floor edge is too uneven for the bottom seal alone to meet cleanly.
Look at the end of the bottom section for the metal or plastic strip that holds the seal. Count the channels, note whether they are slotted or rounded, and measure the distance between them and the width of the door. A photo of the end of the retainer and one of the seal's cross-section is usually enough for the technician to identify the profile before the visit and bring the right roll.
