There isn’t one interval that fits every door. The right timing depends on your door, how often you use it and what the door and opener manufacturers recommend. Start with the care guidance in your manuals, and think about a review sooner if you notice new noise, rough movement or wear. When you call, ask what schedule makes sense for your equipment and what each visit would cover, so you can plan around it.

Maintenance reviews a working door and opener, while a repair fixes a part that has failed or been damaged. A tune up might involve looking over hardware, rollers, tracks and the opener, while a repair deals with something like a broken spring or a cable that has slipped. Sometimes a maintenance visit finds a problem that needs repair, so it helps to ask what’s routine and what isn’t before work begins.

A new noise usually means something has changed, such as worn rollers or hinges, loose hardware, dry moving parts or a track issue. The sound alone doesn’t confirm the cause, since the opener can also make noise. Note when it happens, such as on opening, closing or both, then call and describe it. A loud bang or a door that suddenly feels heavy is different, and the door shouldn’t be used until it has been looked at.

Lubrication is part of routine care, but what to use and where depends on your door and opener manufacturers’ guidance, so check your manuals first. The wrong product or the wrong place can cause problems. Don’t apply anything to springs, cables or bottom brackets, and stay clear of those parts because they hold stored force. If you’re not sure what your door needs, call and ask before you pick up a can.

No service can promise that, but routine care can help you spot wear and small problems earlier. Parts still age, and springs, cables and rollers can fail with little warning. What maintenance gives you is a regular look at the system and a chance to ask about its condition. Treat any promise that a door will never fail with caution, and ask what a visit will and won’t cover.

From a safe distance you can look and listen: note new noises, uneven movement, worn seals and visible wear on rollers or hinges. Don’t touch springs, cables or the bottom brackets, and don’t try to lift or force a door that looks damaged or hangs unevenly. If you see a gap in a spring, a frayed cable or a crooked door, stop using it and call. Describe what you saw so the conversation can start from there.
