For garage door repair in Fairfax, Fairfax County, VA, call Carlton Garage Door Repair.
Every garage door rides on rollers that run inside two metal tracks, and it is lifted by two cables that wind onto drums at the top. When one of those pieces fails, the door can tilt, jam halfway or leave the track entirely. In Fairfax, the most common cause is something hitting the door.
Tight garages, more bumps
Townhouse garages are often narrow, with little room between the car and the track. A mirror, a bumper or a bicycle handlebar can knock the lower track out of line. Once bent, the track pinches a roller, and the door twists as it moves. Detached homes see this too, usually from a car backing out before the door is fully up.
Cables and drums
The lift cables carry the door's weight from the bottom corners. Humidity rusts them where they attach to the bottom bracket, and rusted cables fray. If one breaks or slips off its drum, that side of the door drops. You will see the bottom edge sitting at an angle.
Rollers
Rollers with dry or rusted bearings stop turning and start sliding. That adds friction, and eventually a roller can jump the track. On busy townhouse doors, rollers wear faster simply because they make more trips.
What not to do
Do not run the opener on a door that is crooked or off track. Do not try to pull the rollers back in. The springs are still holding tension. Close off the area and call (571) 736-2137.
The repair
The technician removes tension safely, sets the door back in its tracks, and straightens or replaces bent track. New cable goes on where strands have broken, each side is wound to match, and tired rollers give way to quieter nylon. We finish by checking the balance and testing the safety reverse.
