Most garage door repair should be done by a professional firm that does overhead door installation and repair as they have the tools and knowledge for this type of work You can do some of the repairs yourself if you are moderately mechanical inclined. When a garage door needs repaired there are two main parts that may need repaired. This would be the garage door opener or the door itself. With sufficient patience, effort, and time they can both be easy to fix. If you decide that you want to do the garage door repair yourself make sure that you observe all the safety precautions. You also need to work when there is a lot of daylight available.
In order to determine where the problem is you need to perform two simple tests. The simplest test to do is on the door opener. Use it to see if you can open the door with no problems but if it is not working right then this is your problem but if is working right, test the door. To see if it is the garage door that needs repaired open it manually. It if makes a grinding noise or is difficult to move then the door is the problem. The overhead door moves using spring tension and rolls along metal tracks attached to the garage walls. A heavy spring creates the power that goes through the tension. When you are working on garage door repair you should always check the hardware first to see if there are any issues after checking the door opener.
When it is a garage door repair project the first step is to inspect the metal tracks. You should tighten the mounting brackets that are securing the track to the walls because overtime they can become loose. After closing the garage door look for any breaks, marks, or dents on the tracks. If you see any remove just that section of tract and using a hammer flatten out that section.
To make sure that they are properly aligned use a carpenter’s level. The vertical tracks have to be exactly straight while the horizontal tracks have to have a downward slant. Check to make sure that the alignment of the track is correct along with being parallel to each other. If you see any problems make sure that you only loosen the screws and bolts but do not move them to make the necessary adjustments.
To ensure smooth operation you should clean and lubricate the rollers and tracks. You should also inspect the springs carefully to make sure there are no breakage or wear issues. The fasteners can also become loose and will require maintenance over time so the parts are in correct alignment.
