Service
Any garage door and/or operator needs regular safety checks and maintenance to keep operating properly and safely. The garage door is often the most used door in a home or business. The biggest potential problem lies in the spring system used to lift the door, whether the door is hand operated or if there is an operator.

An extension spring system usually has springs on either side of the door which are in the stretched position when the door is down and are at rest along side the horizontal track when the door is up. When a spring or cable breaks loose, the spring will fly through the air, unless there is a safety cable installed through the length of the spring.

The newer and safer lift system for doors consists of torsion springs mounted on a steel bar on the wall above the door when the door is down. The bar runs through the center of the springs, so that if a spring breaks, the bar prevents the spring from flying loose. Also, if a cable breaks, the bar limits the range of motion.

Following is a list of annual do-it-yourself maintenance for keeping your door and operator running at their peak performance.

  1. Lubricate all moving parts of the door with light household oil, including:
    1. lift cables at the bottom bracket
    2. sheave bearing
    3. lock hardware where surfaces move
    4. torsion spring (between mounting cones only)
    5. steel rollers at the joint of the shaft and head
  2. Tighten loose hinges (straighten or replace defective hinges)
  3. Check rollers for broken wheels, bent shafts, worn out bearings
  4. Check door and track for loose or missing bolts/screws; tighten or replace
  5. Check cables for wear and fraying at bottom bracket and drum

  6. Check for bent track
  7. Do not put grease in the track as this collects dirt and impedes rollers
  8. Lubricate the gear in the operator
  9. Check for worn operator belts, tapes, or chains

We recommend that broken springs be replaced by an experienced technician. Improper release of spring tension has caused serious injury or even death. We also recommend that springs be replaced in pairs (if applicable) so that each spring will provide the same pull. A door should be in good working order to cause the least amount of strain to the operator attached to the door.

Feel free to contact us if you have any questions about maintenance of your door and operator.

We have parts for most major brands.
