Follow these 10 garage door maintenance tips to properly care for your garage door:

Visual Inspection 

Visual Inspection of garage door

The first step in garage door maintenance is to visually inspect your door and opener. Do this monthly to check your garage for any signs of damage, wear and tear or needed repairs.

  • Look at the garage door when it is closed. Make sure it is flush with the ground with no gaps or uneven sections. An unbalanced garage door can cause operation problems.
  • Inspect the exterior surface of the garage door. Look for any cracks, dents, rotted or warped sections. Wooden garage doors are prone to weather damage and may need sealing or paint touch ups.
  • Check the weather stripping along the bottom and sides of the door. Replace any sections that are cracked, brittle or missing to prevent air or water getting in.
  • Examine the door frame and surrounding wall area. Look for any wood rot or gaps where the frame meets the wall. Seal any open joints to keep pests out.
  • Watch as you open and close your garage door. Make sure it moves smoothly with no catching or grinding noises. The door should remain in place when partially open.
  • Inspect the springs, cables, pulleys and other door parts. Look for signs of wear like stretching or fraying. Test the tension by manually lifting the door about halfway. Well balanced doors are easy to lift.
  • Check inside your garage for any grease marks or black dust. Both can indicate worn out rollers and hinges that need replacement.

Clearing Tracks and Lubricating Rollers

The metal tracks that guide your garage door should be kept free of dirt and debris. Rollers and hinges also need periodic lubrication.

  • Disconnect the opener and manually raise the door about halfway up. Use a soft brush or rag to wipe dirt, leaves, cobwebs and other debris off the tracks.
  • Use a vacuum cleaner attachment to clear dust and grit out of the tracks. Focus on the curve of the track where debris tends to collect.
  • Clean all the rollers with a rag. Check for flat spots or wear. Spin each roller bracket to make sure they turn freely without wobbling.
  • Apply a garage door lubricant to the hinges and rollers. Use silicone spray or a lubricant specially made for garage doors. Avoid WD40 as it can attract dirt.
  • Grease all the locking hinges on each side with white lithium grease or machine oil.
  • Lubricate all the torsion springs and pulleys. Be extremely cautious and do not attempt to adjust springs yourself.

Tightening Hardware

Vibration from opening and closing your garage door can cause fasteners to loosen over time. Check all nuts, bolts and screws and tighten any that are loose.

  • Examine the brackets and hinges on both sides. Tighten any loose nuts and bolts with the proper size wrench. Do not over tighten, while that creates problems door opens and closes.
  • Check the bolts and screws that hold lift cables and pulleys in place. Use care not to bend or move the cables. Tighten supports as needed.
  • Make sure the roller shafts are tight. Check that they spin freely after tightening. Add lubricant to keep them operating smoothly.
  • Examine the door track brackets. Tighten any loose lag screws but be careful not to strip them. Make sure tracks are solidly fastened.
  • Check for loose hardware where the curved track connects to the vertical track missing.
  • Inspect bolts where the track attaches to the wall. Tighten if needed to keep the track securely in place.
  • Look for loose screws at the bottom roller bracket and hinges. Use a screwdriver to snug up any that move or wiggle.

Checking Cables and Springs

Garage door cables and torsion springs should be inspected twice a year. Look for any signs of wear and make sure the springs are properly balanced.

Checking Cables and Springs garage door
  • Cables that lift the door run through pulleys and attach to bottom roller brackets. Check for fraying, kinks and signs of rust.
  • Examine the entire length of each cable closely. Look for any broken or bent strands which indicate the cable needs replacing.
  • Test the spring tension by raising the door manually about halfway up. Well balanced doors should stay in place once raised.
  • Check for signs a torsion spring is wound too tight or too loose. The coils should be close together without rubbing.
  • Listen for squeaking noises when opening the door which can indicate worn torsion springs. Have a professional technician adjust or replace springs.
  • Make sure safety cables run through holes in the bottom roller bracket. They prevent injury if a spring breaks and needs replacing.
  • Lubricate the springs with garage door lubricant or silicone spray. Do not attempt to remove or adjust springs yourself due to danger of serious injury.

Testing Balance and Alignment

An unbalanced or misaligned garage door can cause operation problems. Test door balance and alignment twice a year.

  • Raise the door manually about halfway up. It should hold the position on its own when released.
  • If the door drifts down, the springs are too loose. Drifting up indicates over tightened springs. Do not attempt adjusting them.
  • With the door halfway up, examine the gap between the two sides. Uneven gaps indicate misalignment.
  • Make sure sections are flush when closed. Visually check alignment or use a level in the center to look for bowing.
  • Watch as you slowly open and close the door. Sections should transition smoothly without rubbing.
  • Check alignment of track rollers on each side. Roller stems should be straight in their bracket without rubbing.
  • Inspect weather stripping seals for even contact when door is closed. Misaligned doors let in outside air.
  • For minor adjustments, loosen track bolts and tap with a hammer to align. Always re-tighten bolts when finished.

Servicing Chain or Belt Mechanism

If your garage door opener uses a chain or belt drive, periodic servicing is needed for peak performance.

  • Check for signs of wear on the chain or belt every 4-6 months. Look for fraying, cracking and missing teeth or links.
  • Add lubricant formulated specifically for garage door mechanisms. Lubricate the full length of the chain or belt.
  • Examine the sprockets or pulleys that guide the chain or belt. Replace any that are excessively worn or dirty.
  • Check the chain or belt tension. Some slack should be present but the chain or belt should not sag excessively in the middle.
  • Adjust the tension if needed to prevent slipping and premature wear. Do not over tighten. Consult your owner’s manual.
  • Clean the motor and mechanism housing to remove grease, dirt and debris. Check for any loose bolts and tighten if needed.
  • Inspect the alignment of the motor drive and pulley. Use a straightedge to check for improper angle or shifting.

Inspecting Safety Features

Several important safety features should be checked regularly to ensure proper operation. Always test safety reversal systems monthly.

  • Manually pull the release handle on the opener to disengage the door. Make sure the door can be opened and closed smoothly by hand.
  • Return the release mechanism to engaged position after testing. The door should fully engage opener travel limits.
  • Check any photoelectric sensors located near the bottom of the door. Wave your hand in front to make sure they reverse door movement.
  • Use a piece of cardboard or wood to block the door path and trigger reversal when closing. The door should reverse within 1-2 seconds after contact.
  • Test the auto-reverse mechanism by grabbing the door as it closes. There should be adequate sensitivity to stop and reverse direction.
  • Check for frayed or damaged lift cables. Also inspect for missing roller guards and bracket covers which prevent pinch points.
  • Make sure remote transmitters and wall control panels function properly for normal operation. Program devices if needed.

Replacing Weather Stripping in seasonal garage door maintenance

Check weather stripping on your garage door at least twice a year. Replace any sections that are cracked, brittle, loose or missing.

  • Use a putty knife to pry up and remove any old weather stripping around the perimeter of the door. Make sure to remove any remaining adhesive.
  • Clean the sections where new weather stripping will be installed. Remove dirt, debris and old caulk.
  • Measure each side to cut replacements to the proper length. Include an extra 1-2 inches to account for stretching.
  • Peel the paper backing off the self adhesive weather stripping and press it into place on the door. Apply firm pressure for good adhesion.
  • For section joints, cut weather stripping longer than needed. Compress the bulb seal as you install for tight fit.
  • Use a utility knife to trim any excess material. Make sure compressible bulbs fully fill the gaps they are meant to seal.
  • Check for daylight gaps after installation and re-adjust until each section has consistent seal compression when closed.

Cleaning and Maintaining Garage Door Surface

Cleaning and Maintaining Garage Door Surface

Regular cleaning and maintenance is important for wooden, metal and fiberglass garage doors to maintain appearance and prevent damage.

For wooden doors:

  • Remove any mold, mildew and cobwebs with a soft brush or rag. Use a mild detergent and water solution.
  • Reseal any areas where paint is cracking or peeling. Sand down any splinters then prime and paint.
  • Every 1-2 years, apply a fresh coat of exterior grade paint formulated for garage doors. This protects and beautifies the wood.

For metal or fiberglass doors:

  • Hose down the door’s exterior to remove dirt, grime, bird droppings and other debris. Avoid using harsh cleaners.
  • Wash the door’s interior and exterior with a mild detergent and water solution using soft bristle brush. Rinse well with clean water.
  • For tough grease or oil stains, use a degreasing agent formulated for garage door materials. Rinse thoroughly after cleaning.
  • Scrub off any remaining dirt with a soft rag or sponge. Take care not to scratch the door surface.
  • After cleaning, rinse the door and allow to fully dry before operating to prevent water spots.

Addressing Specific Issues

Problems with your garage door may require looking at a specific component such as the opener, hinges or sensors. Target the issue for needed repairs.

Opener problems:

  • Noisy operation could indicate worn opener bearings. Have technician lubricate or replace bearings.
  • Check chains, sprockets and drive belts. Replace damaged or excessively worn parts.
  • Loose opener hardware can cause vibration. Check and tighten all fasteners.

Roller or hinge issues:

  • Sagging door sections or grinding noises indicate worn or bent rollers. Replace damaged rollers.
  • Lubricate all hinges and rollers with garage door lubricant to prevent squeaking and binding.
  • Tighten any loose hinge hardware but do not over tighten or strip roller bracket screws.

Sensor or reversal problems:

  • Check alignment and movement of your garage door with photoelectric eyes. Clear any obstructions and realign if needed.
  • Test auto-reverse mechanism and manually move the door. Adjust sensitivity if door does not reverse properly when obstructed.
  • Make sure all door cables and springs are in good condition. Fraying cables can cause sensor issues.
  • Inspect and tighten all track brackets and hardware if door stops or reverses unevenly when closing.

Replacing Batteries and Bulbs

Replacing Batteries and Bulbs garage door

Routine maintenance involves replacing batteries in remote transmitters and garage door openers. Check backup batteries and replace bulbs as needed.

  • Test remote transmitter range monthly. Replace CR2032 coin cell batteries every 12 months or when range decreases.
  • Check the battery in wall control panels and replace as needed to maintain optimal operation.
  • Examine the emergency release handle LED bulb. Replace burned out bulbs so the release is visible in darkened garages.
