10 Steps on How To Reattach Garage Door Chain

1: Adjust the Restraints

The first step to reattaching the chain is to adjust the various restraints on your door. This will make it possible for you to get at the detached chain and attach it back into place once again. To be able to adjust these restraints, you are going to need a garage door opener that has been installed by a professional. This might seem like the opposite of what you were originally trying to accomplish, but it is no different than any other garage door repair project that you have on your plate right now! 

2: Check For Worn Guides

If you have been using your garage door for an extended period of time, then the chances are good that over time you will see a considerable amount of wear and tear on the tracks that support your garage door.

These worn guides will eventually start to detach from the rest of the garage door, which means trouble for your chain! Ensure that you have checked these guides during your inspection period because if they are not working properly, it will be very difficult to get the chain back into place.

3: Use a Belt and Pulley System

If you are having trouble getting your detached garage door chain in place, then we highly recommend that you check out our belt and pulley system for the garage door! This is an attachment that will help support your entire garage door, so it can’t fall off of the track.

Not only that, but these are extremely easy to install when compared to a traditional garage door brace and will help you out with any other garage door repair service that you need to be done as well!

4: Use a Crank Handle

If you have limited access inside or outside your garage area, we highly recommend that you use a crank handle for the garage door chain. This will be one of your best options if you are having trouble positioning everything properly, and it will come in extremely handy when working with an older generation of garage doors!

5: Operate With Care

Once you have reattached your detached garage door chain, make sure that you operate it with care. You want to be very gentle when opening and closing the garage door because if you are going fast, then there is a chance that your chain could come out of place again.

6: Inspect Your Garage Door Chain

Even after reattaching your detached chain, you still need to inspect it from time to time. You want to make sure that the chain is still tied down in place, or else it could come off again and cause even more problems for you! Not only that, but if you need any garage door opener services, then they can always check it at this time as well.

7: Watch Out For Reverse Chain Linking

You want to make sure that you take caution with your chain because there is a strong possibility that the detached chain might cause some form of reverse linking. This means that when the door goes up, it will go down instead! Not only is this dangerous and could cause accidents, but it could also damage your entire garage door permanently. So make sure that you are taking extra precautions to prevent any sort of reverse linking from occurring.

8: Install New Rails

If the rails that support your garage door system have started to deteriorate over time, then we highly recommend that you call out a professional for assistance! They will be able to replace these with brand new ones so that they can be as sturdy as possible. Since these rails are what support your entire garage door system, you want to make sure that they are in good working order at all times!

9: Be Safe When Operating The Door

It is important to note that the detached garage door chain could cause serious injury if it is not treated with care and respect. If you are having trouble with your chain, then you might want to remove it and replace it with a garage door cable instead. These cables are more flexible than a standard chain and can provide much more support for your system without the risk of causing accidental harm.

10: Don’t Give Up!

Even if you have tried everything on our list and nothing seems to be working, then don’t give up! There are hundreds of possible reasons why your garage door chain might come off. However, if it is a severe issue that needs to be addressed immediately, then we highly recommend that you call out technicians for assistance right away because this could lead to serious injuries if handled improperly.

5 Tips To Prevent Garage Door Chain from Detaching

 Use a Strong Wire
  • When the chain is detached from the door, it may still be connected to the pulley system and can cause harm to you if it comes loose by accident. Inspect your garage door opener often for any signs of movement or issues and repair them immediately.
  • If your garage door has a raised panel on top, use a screwdriver to fasten the chain to it. Otherwise, use a strong wire tie attached to two hooks at the top and bottom of the panel.
  • If your garage door is exposed to harsh weather such as extreme heat or rain, you must use high-quality lubricants on its moving parts; otherwise, rust might occur and cause issues later on.
  • When the chain is in place, use your fingers to make sure it is properly positioned, and replace any part of the chain that looks worn out or rusty. Replace all damaged parts before you operate your garage door again.
  • If you live in an area where extreme weathers are common, consider buying a commercial-grade chain that will withstand any weather condition.


When you have a detached garage door chain, it is important to act quickly. As time passes, the chain can become looser and looser, which will result in an even bigger problem when trying to reattach your chains.
