The Findings That Come Up Again and Again

They check different things. Lay a solid object flat on the floor in the door's path and close the door: it has to make contact, reverse, and travel back up. Then break the photo-eye beam mid-travel: the door has to reverse without touching anything at all.

If a door needs a shove to get moving, or the force setting has been turned up so it will close, then it has been adjusted around a mechanical fault instead of having the fault fixed. That distinction is the heart of an inspection. An opener wound to full force will close over an obstruction, and it will keep doing so right up until it closes on something that matters.

Highland Park has an active resale market, and garage doors turn up in inspection reports regularly. The recurring items are extension springs with no containment cable, a missing or seized emergency release, rusted or frayed lift cables in older detached garages, a door that will not hold its balance, and openers old enough to predate current sensor requirements.

Having those looked at before a listing is straightforward. Having them looked at after a buyer's inspector has written them up is the same work with less time to do it in. You get the same list either way, in plain language, with the items that need doing now kept separate from the ones that do not.
