Garage Door Repairs
Generally, a garage door is moved by an electric opener which turns a trolley that slides along a track. The track is supported by hanging rollers that are usually mounted on hinges. The weight of the door is supported by springs and cables. The door and springs, and other components that make up the door, are often made of metals that wear out and break. Garage door components often need to be replaced, and unlike garage doors, which are expensive, the parts are not.
As with any task involving repair work, knowledge of what can go wrong is helpful in isolating the source of the problem. However, it is also important to have a basic idea of the normal functioning of the system. With garage door systems, listening to the door as it is opened and closed will often help localize the bad component.
Before calling for service, it is a good idea to check the tracks. The mounts can often become loose, and when this happens, the tracks will not be aligned, and the door will bind. If the tracks are badly bent, they should be replaced. Tracks can be adjusted by loosening the mounts and then pushed back into place.
CABLES AND SPRINGS
Mechanisms-wise, a door’s motor or your arm on a manual door controls the movement of a door. The springs do the heavy lifting. A broken spring makes a door feel very heavy and a [door] motor stops working. Visibly broken springs on a sectional door shows a clear gap on the bar where the springs are mounted.
Other mounts on that bar are drum wound sectional door rolls. A broken or worn cable will cause the door to hang on it’s mounting.
A garage door’s springs and cables hold a lot of tension. Tension can be released on a garage door’s springs and cables by a garage door engineer.
OTHER ISSUES
Worn out rollers and hinges make a squeaking or grinding sound. These sounds can be temporarily fixed with lube but over time, more lube will be needed and eventual replacement will be required. Fixed parts can also become loose due to vibration, and over time, work their way out completely.
A door that is off its track can happen due to a door that has been physically forced to close. When a door is off its track it can also drop closed. A door that does this is most likely closing against something. A garage door engineer should be called to re-align the door’s sensors or adjust the opener.
Aging timber doors develop cracks and gaps. Some of these can be fixed, but if a door has numerous issues with failing components, then a door made of a different material may be a better long-term solution.
When to replace a door
There are circumstances where a repair is not the best use of time and money. If multiple components of the door are failing and/or rusted and rotted beyond repair, then the door should be replaced. The same is true if the door is so old that components are no longer available to repair the door. A good engineer will be able to identify which situation you are in.
The following pages will cover various issues regarding doors and the possible solutions. Check the appropriate page based on the issue your door is having.
