In many cases homeowners think that they need a professional, but with a bit of maintenance they can avoid repairs. There is a lot they can do even without the expensive help of a repairman.
Garage doors and gates over time will require repairs and even replaced parts because of the wear and tear that is normal with them. Opening and closing a garage door will weaken the tension springs that control the door itself. Other things that are normal and will need repair is the motor it self that opens and closes garage doors or even a gate.
Look for references ; Have any of your friends, family and colleagues faced problems with their garage doors? Why not ask them for contact details of the technicians they hired? If they received excellent service, then it is quite likely that you will, too.
If the rollers or other parts seem stuck, you can try brushing on some kerosene to the parts. If they are rusty, use steel wool to take away the rust and lubricate as usual. If they are badly corroded they may need replacement. You also need to take a look at the opener. If it is operated by a drive screw or a chain, you may need to lubricate these parts as well.
