Once the chain is secure, separate it from both sides of the trolley. Disconnect the rail from the header bracket and move the rail off to one side. Slide off the old trolley, and slide on the new one. Reattach the chain and adjust the chain tension. Replacing the trolley on a belt drive and replacing it on a screw drive are similar procedures. A new trolley will cost $25 to $40 depending on your model.
You can choose from three basic types of steel door: (1) steel only; (2) steel with insulation on the inside; and (3) steel on both sides with 1-3/8 to 2 in. of insulation. Other features that add to the cost are thicker insulation and windows, especially insulated windows. The do-it-yourself tensioning systems also add a little to the door’s cost. Be sure to specify exactly what you want.

Locating a contractor - there are many professional overhead garage door companies. It is always advisable to contact at least three different agencies and request a bid or quote for the work. Be sure that each quote includes the costs for a few different types of doors, any installation fees, and the cost of wiring the electronic openers. Standard prices range from:
"I am beyond pleased with the service that Adam provided. I contacted him late on a Friday evening, well after typical work hours, expecting not to hear from him until Monday morning. I was pleasantly surprised to have a message waiting for me on Saturday morning. He was inquisitive about our needs and most eager to answer any of my questions. He assured me that he would contact me early Monday morning, and he did. He came out promptly, assessed our needs, and he finished the job shortly thereafter...all in one day. Again, I am beyond thrilled! Best of luck to this company, we will be recommending them to anyone looking for garage door services."

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.

Step 1: Check the metal tracks inside the garage. Look at the mounting brackets that hold the tracks to the walls. If they're loose, tighten the bolts or screws at the brackets. Working inside the garage with the garage door closed, examine the tracks for dents, crimps, or flat spots. If there are any damaged spots, pound them out with a rubber mallet, or with a hammer and a block of scrap wood. If the tracks are badly damaged, they should be replaced.
A standard double garage door is 7 ft. high by 16 ft. wide. Standard single doors are 7 ft. high by 8 or 9 ft. wide. Because the doors are so large, few home centers and only some garage door stores keep many doors in stock, so expect to order one instead of buying it off the shelf. Garage doors are available in wood, fiberglass and steel. Steel doors, like ours, are light, maintenance-free, affordable, readily available, and have an insulating value as high as R-19.
