The door is stiff or jerky after the house sat empty
Why it happens
Weeks without use let lubricant dry out, and salt and sand build up in the tracks and roller bearings.
Why it matters
A sticking door makes the opener work harder and can trigger the safety reverse, leaving guests unable to close it. Signs to watch for: juddering on the first open, grinding from the rollers, door reverses partway down.
Response
Thom cleans the tracks, lubricates rollers and hinges with the right product, and checks spring balance so the door moves freely again.
