How to Repair a Garage Door

Everyone loves a garage door; they not only add to the beauty of your home but also keep your garage safe but not when it stops functioning as it should. At this point, it can be frustrating; the worst part is that it’s not always easy to detect the cause of the problem. However, you are just in luck, as in this article, we share our thoughts on Garage Door Repair; you will discover some of the problems that causes a defect in garage door and garage door opener and how to fix them..

There are garage doors which operate by making use of spring tension, these garage doors either swing up in a single piece, or they roll up in sections. Whatever the case may be, they are moving on metal tracks along the garage walls with a spring to provide support, and in most cases, when they stop working correctly, then it can be easily repaired.

Below are some tips to help you repair this type of defect in a garage door:

First Step: Take a look at the metal tracks in the garage; focus on the mounting brackets which secure the tracks to the walls. If these mounting brackets are loose, then you will need to tighten the screws or the bolts found at the brackets.

Ensure you are working from inside the garage with the garage doors closed and then precede to check the tracks for defects like flat spots, dents, or crimps. If you notice any flat spot, all you need do is hammer them out using a rubber mallet, or you can make use of a hammer too and a block of wood. However, if the tracks are badly damaged, then it’s best to replace them.

Second Step: Examine the tracks to ensure they are properly aligned. Be sure that the vertical part of the track is plumb while the horizontal tracks should slant a bit downwards (tending towards the back of the garage). If there is no proper alignment, loosen the screws or bolts that hold the mounting bracket in place but do not remove them; after that, tap the tracks carefully until it’s fully positioned in the right place. Again, check the tracks and the level to be sure they are positioned right, once satisfied, tighten the bolts or the screws which hold the mounting bracket.

Third Step: Once done with tightening the screws, clean up the tracks. To do this, use a concentrated household cleaner as this will remove all the dirt, grime, and hardened grease. While cleaning, ensure you do so thoroughly wiping the rollers as well as the tracks until its dry.

Fourth Step: Scan for any loose hardware and, if found, then tighten properly. If it’s a swing-up garage door, examine the plates where you have the spring mounted to be sure the bolts and screws are tight, if it’s not then tightened it. Check the roll-up doors as well, pay particular attention to the hinges which hold the various sections of the door together, if you notice any loose screw, tighten them, and if they are damaged, then you will need to replace such hinges.

If it’s an issue of sagging of one part of the door, then it is most times corrected by merely servicing the hinges. If it’s the issue of an enlarged screw hole, the screw can be replaced with something longer, but which is of the same diameter. Ensure you use a plug that is hollow fiber then dip it in carpenter’s glue and use along with the brand new screw.

For cases involving cracking of the wood at the hinge, it can be fixed by removing the hinge, then fill up the screw holes and the cracks with wood fillers. Allow the wood filler to dry up, after which the hinge can then be replaced. If you are able to, move the hinge onto a wood surface.

Caution: If your garage door has a single torsion spring located at the middle of the garage door, it’s best not to try repairing it yourself. This is because the tension of the door is so massive that the spring can injure you, and since you are not a professional at it, it’s better to call a professional garage door repairer rather than attempt to fix it yourself.

Yes, your garage door could be malfunctioning as a result of a defect on the garage door, but sometimes this is not the case. The problem can also be traced to the garage door opener.

How to Repair a Garage Door Opener

A garage door opener is convenient and can also be easily installed in any home. You can even install it by yourself; all you need do is follow the detailed instructions that come with the unit.

A regular garage door opener features a reversible motor which drives a carriage along a rail just above the garage door. Connected to the carriage is a drawbar. This drawbar helps to move the door from an open position to a closed position. It has travel limiting devices that halt the door’s movement, especially when it’s fully opened or fully closed. There’s also a relay switch (also called a reversing switch), which changes the direction of the drive from a closing position to an opening position and then back again.

Nowadays, most modern garage door openers come with radio receivers, which enable the garage door to be opened just by sending a signal from an electronic module in your automobile.

As fancy and convenient as these garage door openers are, they are sometimes fraught with problems, but these too can be fixed. Below are some of these problems and how to fix them:

  1. Garage Doors Refuse To Close All The Way

In a situation like this, the problem isn’t with opening the door as it usually opens; the problem, however, comes when it’s time to close it, that’s when the remote refuses to function. This could be a result of some things.

First, there could be something blocking the sensor, so it’s best to check. Sensors are electronic eyes located at the bottom of the door track found on both sides. These sensors need to have a clear sight between them to enable them to function effectively.

Secondly, it could be as a result of inefficiency of the roller. If the rollers are too rusty or severely damaged, then it needs to be replaced, but if it’s only a matter of stiffness, then apply some silicone lubricant to ease up the motion.

Lastly, it could be as a result of the limit switch. The limit switch is what tells the door when its time to stop moving (for safety reasons). If the setting of the limit switch is wrong, then the door can stop running, hence its best to set it the right way if noticed.

  • Garage Door Doesn’t Open All The Way

If your garage door refuses to open completely, then it’s a problem that needs to be fixed, and just like the first scenario, the problem is usually with the garage door opener. The solution to fixing this problem is similar to the approach taken in the first scenario.

For instance, rusted or damaged rollers could be the cause of the problem as rusted or damaged rollers often find it difficult rolling correctly.

Examine the rollers to ensure they are working as they should. If they are not due to being rusty, lubricate them with silicon, and if badly damaged, then there is a need to replace the rollers.

Again, just like there is a limit switch for closing garage doors for safety purposes, it’s also the case in opening garage doors. This switch may be far from the motor unit, and this can interrupt the connection between the switch and the door, thereby preventing the door from responding to the switch. So, you should be close enough before using the switch, and if the switch is broken, then it needs to be replaced.

  • Switch Refuses to Function

Clicking your garage door remote without a response can be quiet frustrating, but by checking, you could discover what the problem is.

First, you must ensure you are not tapping the remote when out of range. If you are too far away from the garage door, then there is a high tendency that the door will not respond. If that’s not the cause, then try using the wall switch to open and close the door; if this response, then it’s evident that there is a problem with the switch.

You could try replacing the batteries of the remote as they may have a rundown, after which you should try using it again, often, the door starts responding again. You may want also to check the antenna located on the motor unit, the antenna should be hanging down to enable the signal to reach it well enough.

  • Garage Door Reverses Before Or After It Hits The Floor

If your garage door reverses before or after it hits the floor, the problem is most likely from the close-force setting. This is a setting that controls how much force is accepted when the garage door is being closed. With a change in its setting, the quantity of friction needed to be felt before the motor shuts off changes too.

This means that if the setting is off, then it may take a bit of friction from the tracks to trick the motor into thinking it’s reached the ground level and then come to a halt. Things such as damaged or rusty rollers can develop more friction, thereby creating the same problem. Hence, ensure you check the rollers and its setting to be sure everything is functioning as it should.

If the garage door closes fully then reverses to open again, the problem is likely from the close-limit switch. To fix this, adjust the close-limit switch.

  • Motor Still Runs Even After The Garage Door Has Closed

Ideally, the motor of a garage door should stop running after the door has been closed. However, if this doesn’t happen, then there is a problem with the system, it’s an uncommon problem, but it still occurs especially after installing the garage door opener for the first time.

It is related to the up-limit switch. Hence there is a need to place the switch at the right distance from the motor to enable the door close completely and also enable the motor to stop running. Try to make little adjustments such as moving the up-limit switch far but do so in gradual steps while checking if the door closes completely and the motor halts its running.

  • The Garage Door Sticks When It’s Being Opened Or Closed

If, when opening your garage door, it sticks, then it’s an indication that there is a problem with the rollers or the tracks. Therefore, it’s best to check if the tracks and rollers are clean and free from debris or anything that can block its path.

If all checks out, then the problem is likely due to rusty or broken rollers. As such, you will have to replace them if they are badly damaged or lubricate them if they are rusty. Once everything has been cleaned up, fixed, and aligned correctly, then it should stop getting stuck.


Without an idea of the cause of the problem, you are likely to be very frustrated, and that’s understandable. Still, it’s more important to be calm and look at the situation objectively rather than give in to your frustration. Often, you will discover it’s just a minor problem that you can fix yourself.

Being able to fix these problems yourself gives you a sense of satisfaction and also saves you money that would have been given to professionals to get the same job done. 

Just ensure that while trying to fix the problem, you are cautious as you could hurt yourself otherwise. Be careful while using a ladder or working on the electrical aspects as safety is more important than trying to get it done quickly.

 If, after trying all you can the problem persists, then contact a professional technician.
