Doors to the garage usually open and close more than a dozen times a day. Routine maintenance is essential for proper continued functioning. Here’s a routine maintenance checklist and easy fixes that every helpful homeowner will do without any trouble. Checkout a replacement installed for more info.
Each year, these techniques are prescribed three or four times:
Clean the door outside with a stiff brush and mild detergent. Repain or brush peeling, chipped or broken paint, particularly when exposed wood is present.
Use a weather vinyl cleaner to stripe the bottom and frame around. Lubricate with a silicone product to retain flexibility in stripping.
Inspect rollers to determine damage. New rollers can be bought at garage door dealers or at home improvement centres. Missing or tired rollers are removed quickly. First, use a socket wrench to undo the roller hinge keeping bolts in position, and detach bent rollers. Attach rollers to remove and fasten bolts to the hinge.
Test door tracks to insure they are consistent with a point. If not, simply loosen the bolts / screws which keep the track to the wall and change the track, but don’t remove. Test the Level alignment. Refasten the bolts / screws, once the line is smooth.
Test mounting brackets bringing the tracks onto the walls. If the bolts / screws are loose secure. Check from the garage inside with the door closed to see if there are dents, flat spots or crimping in the tracks. These can be pounded with a rubber mallet, or hammer and wood block; avoid using a metal hammer that could easily cause additional damage. Professional garage door installer needs to replace badly damaged tracks.
Check for hardware loose, and fix where appropriate. Test swing-up doors on plates where the spring is placed to make loose screws. Test roll-up doors on hinges which keep door sections together for loose screws. Sagging of the door on one side can be fixed by locking hinges with fresh screws; where appropriate, filling widened gaps with wood filler and longer screws.
By shifting the spring hook to the next spot, test the springs and change the tension on swing-up doors. Pulling the cable through the plate at the top of the door will change the tension on roll-up door springs which have a pulley. Re-knot to conservation of stress at the edge.
Caution: The average homeowner can not restore a roll-up door which has a single torsion spring in the center of the frame. The spring tension is big enough to cause serious injury. Doors with this sort of spring need a skilled garage repairman to repair them.
