Chris was very professional & thorough. He arrived on time & was able to answer all questions that I had. I was extremely satisfied with the quality of the work he performed. I spoke several times on the phone with Mrs. Carol who keep me informed prior to, during, and after the installation of my garage door. She was very professional, easy to talk with and resolved any misunderstanding that I had.
With over 300 independently moving parts, your garage door is a deceptively complex piece of equipment. To help prevent malfunctions and break-downs, it is a good idea to occasionally perform a garage door tune-up to keep all of these parts in good working order. A regular tune-up service by a Sears professional can prevent unexpected door problems and prolong the life of your existing equipment.
While generally easy to install, without an Introduction or Basic Principles of Operation as a preamble, you will likely have the same issues I did. Read on for the lessons I learned and tips that will save your hair. I will explain each of the major elements of the system and provide suggestions to improve your probability of a successful installation.
Sectional: Also known as a raised panel door, this door is the most common. It is made of several horizontal panels hinged together, fitted with wheels and mounted within a track. The biggest advantage of this door is it takes up relatively little space and easily controlled with a standard remote garage door opener for a nominal cost. Their moving parts are readily accessible which can keep repair costs low. The average cost for sectional door repairs is $128.
Tom was right on time, moved efficiently and finished very quickly. Door has never sounded so quiet. Love the new rollers and the door is adjusted perfectly. Being a DYI and the guy who installed the opener I never could get the adjustments right for the range of door movement. He adjusted it perfectly. Also received (upon my request) a quote (word of mouth at this point, due to other projects on our list) for new door, installation, etc. I was VERY happy with the quote. It will speed up our ability to purchase a new door and will go with this company for it. Thanks again for a very pleasant experience.
Now check the springs. There will be just one on a single-car garage, two on a two-car garage. Roll-up doors are operated by torsion springs, controlled by cables on pulleys. Two-car models can be adjusted by pulling the cable further through the plate above the door, then knotting the end to hold the newly established tension. One-car roll-up door springs should only be adjusted by a professional, as there is such a great amount of tension on the one spring that you could be injured when trying to adjust it yourself. Swing-up door springs are hooked on each side of the door into special notches or holes. To adjust the tension on these springs, simply move the spring hooks to the next notch.
