An extension spring counterbalance system consists of a pair of stretched springs running parallel to the horizontal tracks. The springs lift the door through a system of pulleys and counterbalance cables running from the bottom corner brackets through the pulleys. When the door is raised, the springs contract, thus lifting the door as the tension is released. Typically these springs are made of 11 gauge galvanized steel, and the lengths of these springs are based on the height of the garage door in question. Their lifting weight capacity can best be identified by the color that is painted on the ends of the springs.
Because garage door springs and openers can degrade over time, it’s important to occasionally test this safety feature. With the garage door open, place a solid object such as a 2-by-4 board or a cinder block where the door will close. Never test any safety feature using your or another person’s body. With the board or block in place, press the close button. If working properly, the garage door should close on the obstruction and immediately reverse the closing operation when it comes in contact with it.
Response time was excellent. Alex was punctual, friendly, and knowledgeable. I had a 23 year old opener that I needed to replace. He came out and replaced it. It didn't take too long and he was professional in every way. I hope this new unit gives the service and longevity of the old one. We will see. From my experience with Precision Overhead Garage Door Service and Alex, I would use them again and I recommend them.read more
Step 5: Check for loose hardware, and tighten as needed. On swing-up doors, check the plates where the spring is mounted to be sure the screws are tight, and tighten any loose screws. On roll-up doors, check the hinges that hold the sections of the door together; tighten any loose screws, and replace any damaged hinges. Sagging at one side of the door can often be corrected by servicing the hinges. If a screw hole is enlarged, replace the screw with a longer one of the same diameter, and use a hollow fiber plug, dipped in carpenters' glue, with the new screw. If the wood is cracked at a hinge, remove the hinge and fill the cracks and the screw holes with wood filler. Let the filler dry and then replace the hinge. If possible, move the hinge onto solid wood.
For Sears Garage Door Installation and Repair Services, making your garage door safe is as important as making it function well. For this reason, all of our repair services and tune-ups feature a 20-point safety check. Our technician will carefully examine your garage door panels, springs, sensors, safety release, hardware, track, and more. This ensures that, not only has our work been done well, but that your garage door poses no danger to your vehicles or family. Due to the intricacy of garage door systems, only garage service professionals should attempt to adjust, repair, or service door equipment.

Step 2: Check the tracks with a level to make sure they're properly aligned. Horizontal tracks should slant slightly down toward the back of the garage; with roll-up doors, the vertical sections of track should be exactly plumb. Both tracks must be at the same height on the garage walls. If the tracks are not properly aligned, loosen but do not remove the screws or bolts that hold the mounting brackets, and tap the tracks carefully into position. Recheck the tracks with the level to make sure they're in the right position; then tighten the screws or bolts at the mounting brackets.
Repair Sagging Garage Doors – As doors and homes age, they can shift and move and sometimes this results in a garage door that needs to be realigned or reinforced. We will send a technician to your home to adjust the doors and to inspect the entire opening to make sure the door isn’t damaged. Once we understand the problem, we will fix the needed parts and make any adjustments to the door.

To help prevent garage door problems from occurring, the Institute of Door Dealer Education and Accreditation recommends monthly maintenance, including testing that the garage door opener is operational and inspection of the springs, rollers, pulleys, cables and track. Wipe down the tracks, preferably with a microfiber cloth to prevent lint from being left behind. Also, make sure to keep all the metal moving parts lubricated. However, do not lubricate plastic parts. Never reuse an old track with new panels.


Brian Printz showed up on time and was very polite and professional, He performed a complete door overhaul in less than an hour, during the door overhaul the rollers were replaced also, I will have to say II have never heard such a quiet door when lifting or closing. I am very happy. The price was a little more than expected but the way I look at it another spring will eventually brake and it will be covered under the lifetime warranty.
Align the upper roller tracks by carefully lifting the door halfway. Lock it in place with two locking pliers, and install the supporting brackets on the back of the rails using 1-1/4 in. perforated angle iron (available at home centers and hardware stores). Install 1-1/2 x 1/4 in. stop bolts, with the threads to the inside of the track, at the end of each upper track.
Hmmm...Intro to E12...looks suspiciously like a freehand angled cut on that contractor saw... Yes, the riving knife might save you from a dangerous kickback...but still a very bad idea.. Why not a 'safety segment' explaining kickback and why you should not do this (styrofoam demo, back side of the blade teeth rising up grabbing the foam and throwing it back at you...)
Center and level the first section after you install the brackets. The door must be level even if the floor isn’t, so use shims under the section to level it. The rubber gasket on the bottom section will fill the gaps created by an unlevel floor. To hold the level in place, tape it to the section. To hold the section in place, lightly toenail a 16d nail into the frame and bend it over the section. Add brackets and rollers before setting them in place and stack one section on top of another, toenailing as you go up.

Roller doors ("Sheet Doors"-USA) are usually constructed of corrugated steel. They evolved from cover window and door coverings.[4] Other materials can be used (e.g.; transparent corrugated fibreglass) where strong impact resistance is not required. Corrugations give the door strength against impacts. A typical single car garage roller door has a preloaded spring inside the rolling mechanism. The spring reduces the effort required to open the door. Larger roller doors in commercial premises are not sprung (except USA) and use a manual pulley and chain system or a geared motor to raise and lower (roll up and roll down) the door. Roller doors cannot be effectively insulated.
