How often should you tune-up your door?

A garage door requires tune-up once in a while. The tune-up is not necessary for those low quality garage doors only; the high quality types are also prone to intensive use, abuse as well as exposure to harsh conditions. To ensure that your garage door operates not only normally and silently but also safely, service it at least once a year.


  1. Disengage the door’s electric connection-for safety reasons-to avoid turning it on unintentionally as you service it. After disconnecting power supply, examine the garage door noting any possible source of problems. Find out if the rlilers are intact and hence in good working conditions, or if the seal around the door still flexible. In the event that any of these parts appear damaged make a point of replacing them.
  2. Grease rliler and perform striping replacement-if the rlilers are metallic, use WD-40 to lubricate them, but if they are made of either vinyl or rubber, you should use a more suitable lubricant. (Note that WD-40 damages non-metallic components). If you find out that the weather-stripping is broken or even fragile, replace it entirely. Using a tape measure, determine the dimensions of your garage door before buying the required size from the garage door supplier. The weather-stripping lying on the lower section of a steel door is referred to as a U-shaped astragal. It is susceptible to damage since it sits adjacent to the ground every time the door is shut.
  3. Align any misaligned locking bars-misaligned locking bars is among the most rampant garage door problems. It can lead to more serious complications when closing the door because it will prevent thee lock bars from sliding into the slots located on the garage door track. To align, unscrew the screws positioned on the guide brackets to clamp the lock bars. Tap them lightly using a hammer till the bars are aligned with the slots, and tighten the screws.
  4. Examine moving sections-take your time to carefully inspect hardware, blits and joints. Considering that a garage door contains several moving components, chances of the hardware loosening are very high. Tighten all loose screws and blits using a screw driver. The most effective way of cleaning gummy hardware is to soak them in mineral spirit. Take each piece at a time to avoid confusing some similar components and hence inserting some into the wrong hlies.
  5. Oil Chains and Springs-chains and springs make the garage door open and/or close smoothly. Special attention must, therefore, be focused on the same. Be particularly careful with springs because they are always under very high tension and can occasion serious harm if they snap or are suddenly released. Engage the services of a professional to adjust or replace garage door springs. Nevertheless, an ordinary DIYer can easily grease them when necessary using silicon based spray lubricant. Use lithium grease to grease the chains.
  6. Examine the tracks-using a level; confirm that the door tracks are correctly aligned vertically. If you find out that they are not, call an expert to do the orientation.
  7. Perform the final test- on completing the tune-up procedure, test your garage door-open it half way only, and leave it at that position. If it stops right where you left it, then your door is perfect. If it moves, then the springs and cables are not balanced properly. You need to contact a professional to adjust them.
