Once a month, take 2 minutes to look at your garage door system with the door closed and then with it open. You’re looking for anything that looks wrong, worn, or out of place.

• Look for rust or corrosion on springs, cables, and hardware
• Check that both cables are taut and properly wound on the drums
• Watch the door move — it should travel straight up and down without wobbling or jerking
• Listen for grinding, scraping, or unusual sounds during operation
• Check that the door sits evenly at the bottom when closed

This is the single most impactful thing you can do for your garage door’s longevity. Proper lubrication reduces friction, prevents rust, and dramatically extends the life of springs, rollers, and hinges. In Colorado’s dry climate, lubrication is especially critical — parts dry out faster than in more humid states.

• Use a dedicated garage door lubricant spray (silicone or lithium-based) — NOT WD-40
• Lubricate torsion spring coils from end to end
• Lubricate all roller stems and hinge pivot points (not the roller wheel itself if nylon)
• Lubricate the inside of both tracks lightly — too much attracts debris
• Wipe away any excess — you want a thin film, not dripping

Best lubricants: White Lithium Grease spray, Clopay Pro-Lube, or 3-IN-ONE Garage Door Lubricant.

A properly balanced door is critical for both safety and opener longevity. This simple test takes 30 seconds and can tell you if your springs need attention. Do this test at least twice per year.

• Close the door fully
• Pull the emergency release cord (red handle) to disconnect the opener
• Manually lift the door to about waist height and let go
• The door should stay in place or move only slightly
• If the door falls or rises on its own, the springs are unbalanced — call a professional

Reconnect the opener after testing — pull the cord or press the button per your opener manual.

Modern garage door openers are required by law to stop and reverse if they contact an object while closing. This protects people, pets, and vehicles. Test this monthly — it takes 10 seconds.

• Place a 2×4 flat on the ground in the door’s path
• Close the door — when it contacts the board, it should immediately reverse
• If it doesn’t reverse, the down-force limit is set too high — call a technician to adjust
• Never operate a door that doesn’t pass the reverse test until it’s repaired

The safety sensors (two small boxes at the bottom of your door tracks) can cause the door to reverse or refuse to close if they’re dirty, misaligned, or obstructed. This is one of the most common “my door won’t close” complaints — and it’s often a DIY fix.

• Wipe both sensor lenses with a dry cloth
• Both sensors should have a solid (not blinking) light — one green, one amber/red
• If a light is blinking, the sensors are misaligned — gently adjust the sensor bracket until both are solid
• Clear any cobwebs, dirt, or objects from the sensor path
• Check that sensor mounting brackets are tight and haven’t been bumped out of position

Thousands of open/close cycles create vibration that gradually loosens bolts, nuts, and brackets throughout the door system. A loose bracket can cause alignment problems, accelerate wear, and eventually lead to a door that jumps its tracks.

• Use a socket wrench or ratchet to check all visible bolts on track brackets
• Check hinge fasteners on each door section
• Tighten the bolts on the roller brackets
• Check that the opener’s mounting bolts are secure
• Do not over-tighten — snug is sufficient

Weatherstripping protects your garage from weather, pests, dust, and moisture. In Colorado’s harsh climate, rubber weatherstripping cracks and deteriorates faster than in more temperate regions.

• Check the bottom seal (rubber strip along the bottom of the door) for cracks, gaps, or compression loss
• Check side and top seals for cracking, shrinkage, or separation from the frame
• Bottom seal replacement is a DIY-friendly job — kits available at hardware stores
• Replace cracked or stiff seals — gaps allow cold air, water, and pests in
• Colorado’s UV exposure accelerates seal degradation — check every spring

Rollers carry the full weight of the door as it travels up and down the tracks. Worn rollers cause vibration, noise, and can eventually cause the door to jump off track.

• Look at each roller along both tracks — 10–12 rollers typically per door
• Nylon rollers (white or gray) should show no cracks, chips, or wobble
• Steel rollers should spin freely without grinding
• A wobbling or chipped roller should be replaced — typically $80–$150 for a full set
• Most rollers can be replaced by a tech in under an hour

The vertical and horizontal tracks guide your door’s rollers. Debris, dents, or misalignment in the tracks cause noise, uneven movement, and can jam the door.

• Wipe the inside of both tracks with a damp cloth to remove dirt and lubricant buildup
• Inspect for dents or bends — even small deformations can cause rollers to catch
• Check that tracks are plumb (vertical) using a level — tracks must be straight
• Minor track dents can sometimes be tapped back with a rubber mallet — major damage needs professional realignment
• Do not use grease on the tracks — you want them clean and smooth

The 9 tips above are what you can do yourself. But once a year, a professional inspection catches what you can’t see — spring tension measurement, cable wear assessment, opener force calibration, and documentation of components approaching end of life.

• Best timing in Colorado: fall (October/November) before winter stresses the system
• Costs $89–$120 for a comprehensive 10-point professional inspection
• Our written service summary tells you exactly what was found and what to watch for
• Annual tune-ups typically prevent $300–$500 in emergency repair costs over a door’s lifetime
