Annual Maintenance Checklist

A complete garage door maintenance service covers every component of your door system. Here is what our technicians inspect and service during a professional tune-up:

• Lubrication of all moving parts — We apply professional-grade lithium or silicone lubricant to springs, rollers, hinges, bearings, and the opener chain or screw drive. Proper lubrication reduces friction, noise, and wear on every cycle.
• Door balance test — We disconnect the opener and manually lift the door to the halfway point. A properly balanced door stays in place. If it falls or rises, the springs need adjustment to distribute weight evenly and reduce strain on the opener motor.
• Safety reversal test — We verify that the auto-reverse mechanism functions correctly by placing an object in the door's path. The door must reverse immediately upon contact. We also test the photoelectric sensors to ensure the infrared beam triggers a reversal when broken.
• Visual inspection of cables and drums — We examine cables for fraying, kinks, or wear spots that indicate imminent failure. We check drums for cracks and proper cable winding. Cable failure is dangerous and catching wear early prevents emergency situations.
• Hardware tightening — Vibration from daily use loosens bolts, brackets, and track mounts over time. We tighten all fasteners including hinge bolts, track brackets, opener mounting hardware, and roller brackets to eliminate rattling and ensure structural stability.
• Weatherstrip inspection — We check the bottom weather seal and side seals for cracks, gaps, tears, or compression damage. Deteriorated weatherstripping allows water, pests, and drafts into your garage.
• Track alignment and cleaning — We verify that tracks are plumb, level, and properly spaced. We clean debris from inside the tracks that can obstruct smooth roller movement and cause uneven wear.
• Roller inspection — We examine each roller for cracks, flat spots, and worn bearings. Damaged rollers create noise, vibration, and can cause the door to jump off track.
• Opener force and limit adjustment — We calibrate the opener's force settings and travel limits to match the door's current weight and track position, ensuring smooth starts and stops without slamming or incomplete closing.

Maintenance Tune-Up Pricing

All maintenance services are performed by licensed, background-checked technicians. If we identify a component that needs repair or replacement during the inspection, we provide a separate written estimate for that work. There is never any pressure to approve additional services, and we never perform work without your explicit approval.

Benefits of Regular Garage Door Maintenance

• Extends lifespan by 5 to 10 years — Regular lubrication and adjustment dramatically reduces wear on springs, rollers, and hardware. A well-maintained door system can last 25 to 30 years compared to 15 to 20 years without maintenance.
• Prevents expensive breakdowns — A $89 annual tune-up catches a worn roller before it derails the door ($300+ repair) or identifies a weakening spring before it snaps and damages the opener ($400+ repair). Prevention is always cheaper than emergency service.
• Maintains manufacturer warranty — Most garage door and opener manufacturers require annual professional maintenance to keep warranty coverage active. Skipping maintenance can void your warranty when you need it most.
• Ensures family safety — A garage door weighing 150 to 400 pounds with malfunctioning safety features is a serious hazard. Annual testing verifies that auto-reverse, sensors, and spring tension are all functioning correctly to protect your family and pets.
• Reduces noise and vibration — Dry, unlubricated components create grinding, squeaking, and rattling that disturbs everyone in the house. Fresh lubrication and tightened hardware restore quiet, smooth operation.
• Maintains energy efficiency — Intact weatherstripping and properly sealed panels keep conditioned air in and outside air out. A well-maintained door maintains its insulation value throughout its lifespan.

Seasonal Maintenance Tips for Bay Area Climate

San Mateo's mild coastal climate is generally easy on garage door systems, but certain seasonal conditions deserve attention:

Winter (November through February)

The Bay Area's rainy season brings increased moisture that can accelerate corrosion on unprotected metal components. Check your bottom weatherseal before the rains begin to ensure water is not pooling inside the garage. Verify that your garage door's drainage grading directs water away from the opening. Lubricate springs and hinges in early winter since cooler temperatures make lubricant less effective if it was applied months earlier.

Spring (March through May)

Spring is the ideal time for your annual professional maintenance visit. The mild temperatures allow lubricants to penetrate effectively, and you catch any winter wear before summer heat stresses the system. This is also the best time to touch up paint or stain on wood doors before UV exposure intensifies.

Summer (June through September)

While San Mateo summers are mild compared to inland areas, afternoon sun on west or south-facing garages can heat the door significantly. Ensure your opener's thermal protection is functioning (most modern openers have built-in thermal overload). Check that insulated doors maintain their panel integrity without warping or delamination from heat cycling.

Fall (October through November)

Before winter arrives, inspect weatherstripping one final time. Clear leaves and debris from tracks and the area around the door threshold. Test your battery backup (if equipped) to ensure it works when winter storms cause power outages. This is also a good time to test your safety sensors, as shorter days mean more garage use in low-light conditions when sensor alignment is critical.
