There are a number of things you should check on your
garage door; it can prevent accidents and let you know that you need
a new door.
1. Tighten all nuts and bolts. Because a garage door is constantly moving,
vibrations and rotations can loosen joints and eventually cause severe
structural damage.
2. If you have a sectional roll-down door, check the rollers on your
door. Because they are constantly running up and down your garage on
a metal track, they can begin to show signs of wear and tear. Nylon
rollers are known to crack as they age, and worn bearings in steel roller
cause the roller to bend and tilt.
3. Check the condition of the cable that lifts the door when it opens.
It can fray and cause your door to come crashing down if it eventually
snaps.
4. The chain that runs from the door opener to the door should be frequently
oiled. Without lubrication, tearing and scratching can occur.
These common problems that affect garage doors should be done to ensure
that your door isn’t wearing down, but make sure that you use safety
when working closely with it. Remember to unplug the door opener so
that it can’t activate without you realizing it. Do not attempt
to repair or remove any springs under tension on your garage door. They
can whip out and injure you if improperly manipulated and should only
be handled by professionals.
