Replacing One Section Instead of a Whole Wilmette Door

Most of the section damage we see in Wilmette happens in reverse, at walking pace, within a few feet of the building. Backing a wide vehicle out of a single-width alley garage leaves very little clearance on either side, and the door is what catches the mirror, the tailgate or the corner of a trailer.

The useful thing about a garage door is that it is built in horizontal sections, and sections can be bought one at a time. A dent in one of them does not automatically mean a new door.

Which Section Took the Hit Decides the Job

The middle sections are the straightforward ones. They carry hinges and rollers and nothing else, so swapping one is contained work. The bottom section is a different proposition, because it holds the bottom brackets that the lifting cables attach to, along with the seal and its retainer. Damage there is structural and it is a safety item, not a cosmetic one.

The top section carries the top fixtures and, on an automatic door, the bracket for the operator arm. A cracked or bowed top section lets that arm work loose, and once the fastener starts moving it tears the skin around it a little more every time the door runs.

Matching a Section on a Door That May Be Out of Production

To order a section we need the manufacturer, the model line, the panel design, the surface embossing, the steel gauge, the insulation construction and the exact section height. Most of that comes off a label inside the end stile or on the top section. Where the label has long gone, it can usually be identified from the hardware and the panel profile.

Colour is the part worth being blunt about. A door that has faced west across an open drive for fifteen years has drifted a long way from its factory finish, and a brand new section beside it reads brighter. On a garage nobody sees from the street that may be fine. On a street-facing door it usually means painting the new section to the weathered ones, or painting the door as a whole.

When Replacing the Whole Door Is the Honest Answer

Three or more damaged sections, a profile with no current equivalent, or a door whose hardware is worn out anyway, and section replacement stops adding up. At that point you are rebuilding an old door one piece at a time and paying twice for the privilege.

You get told which side of that line your door sits on at the estimate, with the reasoning behind it, and the decision stays yours. Repairing one section on a door with another decade in it is a good outcome. Repairing one section on a door that needs two more next spring is not.

Questions

Wilmette questions about this job

The dent is shallow. Can it just be pushed back out?

On a single-skin steel door, sometimes, though it never comes back properly flat. On an insulated door the steel skin is bonded to a foam core, so pulling the dent separates skin from foam and leaves a ripple that shows up in low sun. Those get replaced rather than repaired.

The door still opens and closes fine. Is there any hurry?

It depends where the damage is. A dent in the flat of a middle section can wait for a convenient appointment. A crack running through a stile at a hinge cannot, because that is the point the fastener pulls against on every cycle, and when it releases the section folds.

Our door is old and the maker no longer lists it. Then what?

We check the current lines for a matching profile first, since panel designs get carried for years. If nothing matches, the choice is a plain section painted to blend or a full replacement. We would rather show you both than order something that arrives looking wrong.
