Replacing One Section of a Mount Prospect Garage Door

Plenty of two-car garages around here were built as two single openings with a post between them rather than one wide one. That doubles the matching problem. The replacement section has to match the rest of the damaged door, and the repaired door then has to still read as a pair with the one next to it from the pavement.

What has to line up is the panel profile, the embossing, the steel gauge and the finish. A section from the factory sits alongside twenty years of sun and weather, and on a south or west-facing elevation that difference shows. Sometimes the answer is a correct-profile section and paint across the whole door; sometimes it is honest to say the pair will never match again and to talk about the alternative.

Damage rarely stops at the dent. Something that hit hard enough to crease a section usually also jumped a roller out of the channel, tweaked a jamb bracket, or let a cable go slack off the drum. Fitting a new section onto bent hardware puts a straight panel on a crooked door.

The other case is slower. A bottom section that has rusted from the inside out, where the floor seal held meltwater against the steel year after year, is telling you about the section above it as well. If a door is already carrying two or three replaced sections on original track and original springs, we will say plainly when the repair has stopped being the sensible option.
