Spring Issues - Unless it is due to an obstruction of some type, uneven movement of your garage door is likely caused by a problem with the spring mechanism. Roll-up doors generally have one center-mounted torsion spring. The tension on torsion springs is great. Therefore, it is necessary to call a professional for any repairs to this type of spring mechanism to avoid serious injury. Because replacement of these springs or cables in a garage door can take at least two or three hours of labor, costs can average $300 or more.

Squealing, screeching, or grinding noises from your garage door are usually indicative of a lack of lubricant or an accumulation of dirt or debris in the tracks. When removing debris, do not use harsh chemicals to clean the tracks. Once the track is clean, coat it with lubricant designed especially for garage doors, if possible. If you do not have access to this special type of lubricant, you can use WD-40 on the tracks and hardware.
I learn a lot from this show and it help in my building maintenance job. i like this about the regulator on gas meter but for the cut away I know it had to be that way but Richard could you have mentioned that there was a vent on the regulator. I had a coworker ask me to check the vent and make sure it was clear, but from your cut away and no mention of a vent in the demo I didn't know there was a vent on the regulator so for next time there may need to be 2 cut aways explaining what the meter is and how to be safe.
Though you can do some maintenance to your garage doors on your own, it may be a good idea to schedule routine inspections with a professional. A typical service call will include a manual inspection of the door and opener. Then adjustments can be made including spring tension, chain/belt tension, limits and force adjustments and door lubrication. Fees for this service vary from place to place, but garage door repairs typically cost between $147 and $340.
John, the service tech, was able to show up 2 hours ahead of schedule which worked out great. He knew the problem and readily offered a fix to repair the contractor grade spring and roll bar to a heavier duty version. Repair was done in a short period time and I could not be happier with the end result. He was friendly and knowledgeable and cared about getting it done right. Very pleased with the work and warranty.
Vinyl constructed garage doors are designed from the same materials as siding and window casements that you see on many homes.  This is a material that is lightweight and easy to work with.  Homeowners will find that vinyl is available in a wide range of color selections that will match the look of their home.  Vinyl can crack and bend out of shape if not properly taken care of.

The electronics should also be inspected before or after investing in the cost of replacing the garage door panel to make sure your door will operate properly. The sensors prevent the door from closing on someone's foot or a pet. If they don't work, someone could be injured. Also check to make sure the door opener works, since you could otherwise be locked out of your garage.
Carriage: These doors mimic the look of doors found on old carriage houses in the days of horses and buggies. Because of their rustic look, they are often favored in the West and Southwest of the United States. The doors swing open like oversized French doors and hang from jambs on hinges. With their unique look, they create an area of visual interest for your home and are quite energy efficient. The downside is they require a considerable amount of clearance to work properly. Because most carriage garage doors are largely composed of wood, you may need to replace deteriorating or rotting door materials. The average cost for carriage garage door repairs is $133.
