Then Photo-eye alignment.
The sensors near the floor are out of line or dirty; a clean and re-aim usually restores normal closing.

A renovation changes the face of a house, and the old garage door can suddenly look out of place. We help homeowners in Maple Hills pick panel styles, window inserts, colours and hardware that suit the new exterior, then install the door plumb and level so it looks intended rather than added.

Every square is one home in a hundred.
An inspection looks and reports; a tune-up looks, reports and then does the maintenance. Both begin with an observed cycle and a check of hardware, balance, sensors and reversal. A tune-up goes on to tighten fasteners, lubricate the moving points, adjust the opener and align the photo-eyes, and it may swap a worn roller or a bottom seal on the spot. If you want the door serviced rather than assessed, the tune-up is the one to book.
If the wood stop is sound, straight and not buried in paint, a new fin nailed to its face is the simpler choice and keeps the look of the trim. If the stop is cracked, soft or has been painted many times, a one-piece vinyl stop replaces it entirely, needs no paint and cannot rot. The technician checks the stop and recommends one or the other on site.
An opener is built to guide a balanced door, and every wheel that binds, wobbles or grinds adds resistance it has to overcome across the whole travel. It works harder, runs hotter, and may trip its force limit or reverse partway through a cycle. After roller replacement the technician confirms the door holds its own weight with the opener released, then checks the opener's force setting and its reversal on a test block, since a door that moves freely often needs those settings reduced.
Steel flexed often enough eventually cracks, and several things speed that up. A door out of balance is dragged by the opener, and every hinge takes the strain. A seized roller twists its hinge on each trip. A track out of line pinches the panels at the curve. A wide panel without a strut flexes at the joint. Corrosion at the low hinges thins the steel. The technician looks for which of these was at work so the new hinge is spared the same stress.
