Garage Door Tune-Up and Maintenance in San Diego

• The door is louder than it used to be: squeaks, pops or a rumble from the rollers.
• It moves in jerks, hesitates, or slows down near the top or bottom.
• With the opener released, the door drifts down or shoots up when you let go halfway.
• Rust is showing on the springs, cables or bottom brackets.
• The opener strains or the door reverses now and then for no clear reason.
• The bottom seal is cracked or flattened, letting in light, dust or water.

Near the coast, salt air and the marine layer keep metal parts damp, and springs, cables and hinges rust from the outside in. Inland, heat and dust dry out lubricant and grit gets into roller bearings. Everywhere, the garage is often the main entrance to the house, so the door can run several cycles a day, and every cycle wears the springs, rollers and opener a little more. Loose bolts are part of it as well: the vibration of every cycle slowly backs out the hinge and track fasteners.

1. Inspect the springs, cables, drums, bearings and bottom brackets for wear, rust and fraying.
2. Test the balance with the opener released and adjust spring tension if the door drifts.
3. Check every roller and hinge, and tighten the hinge and track fasteners. Bottom brackets are inspected but never loosened.
4. Clean the tracks and check their alignment; tracks are wiped, not greased.
5. Lubricate hinges, roller bearings, the springs and the shaft bearings with a garage door lubricant.
6. Check the opener: travel limits, close force, chain or belt tension, safety sensors and the auto-reverse.
7. Check the bottom seal and the emergency release, and test the remotes and wall control.

A balanced door is one whose springs carry nearly all of its weight, so it stays put when released halfway and the opener only has to guide it. As springs age they lose tension, the door gets heavier at the bottom of its travel, and the opener makes up the difference on every cycle. The opener does not complain until its gear or board gives out. Checking and correcting the balance is the single part of a tune-up that protects the opener most.

Opener manuals ask owners to test the safety reverse regularly, and it takes a minute. Lay a piece of wood flat on the floor under the door and close it with the opener: the door should stop and reverse when it touches the wood. Then wave something through the sensor beam while the door closes; it should reverse. Look at the springs and cables for rust or broken strands, and listen for new noises. If the door fails the reverse test, stop using the opener until it is fixed.

What not to do: do not tighten or loosen the bolts on the bottom brackets, do not adjust the springs, and do not spray household penetrating oil on the springs or tracks as a lubricant. It attracts dirt and dries out quickly. A silicone or lithium-based garage door lubricant is the right product for hinges, bearings and springs.

A tune-up keeps a working door working. If something is already broken, the visit is a repair: a broken spring belongs on the spring repair page, worn rollers on the roller page, and an opener that will not respond on the opener repair and installation page. When a tune-up finds a part near the end of its life, you can decide whether to replace it on that visit or plan for it.

Once a year suits most homes. A door near the ocean, or one that runs many times a day, benefits from a closer schedule. Book a tune-up when the door starts to sound or feel different, or before a long trip so the house is not left with a door that might fail. Call (619) 666-6054 to set a time.
