Guest 9232954 -- check out the other answers for this question, and the links below the answers for even more - seems from $125-400 range from different contributors (should be replaced in pairs for balanced lifting unless one spring is quite new), about $200-250 or 300 seems a common charge. The springs themselves generally run about $20-50 each depending on lead they have to carry.
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.
6.8 Properly tightened screws will loosen with less than a turn. Once you loosen a set screw, keep at least one bar in the cone AT ALL TIMES until the spring is fully unwound. Many cones have been over-tightened. The spring may unwind 1/4 turn and not unwind any more until one of the set screws is loosened some more. You may need to completely remove the set screws. The shaft may be distorted and the cone still may not unwind at all.
Overhead garage doors weigh hundreds of pounds, and doors that are not properly maintained or which are equipped with older automatic garage door openers can be safety time bombs. All too common are the tragic stories of garage doors injuring or even killing children or pets who found themselves underneath a closing door. Modern automatic door openers with auto-stop and auto-reverse mechanisms have greatly reduced such accidents, but mishaps can still occur if the door and door opener are not properly maintained.

If your door feels heavy, it is likely that your springs have started to wear down and are no longer capable of bearing the weight that they once did. Now, don’t worry, just because a spring is starting to lose its strength doesn’t mean it will snap at any moment. However, simultaneously, a weak spring isn’t any safer to try and repair on your own.

8.5 Inspect the bearing. Lube it with motor oil, spray lithium, or spray lubriplate grease. Do not use WD-40. If the shaft is worn and the bearing is seized and you can't free it, replace the bearing. Or, if you have bearings labeled "ADH" we recommend replacing them. I find very few other bearings that need to be replaced. However, if you do need to replace the bearing and you do not have a new one, you can replace it at a later date. You'll find a quick way to do this at our End Bearing Plate Replacement instruction page.

If your door has two springs, most professionals and research online says that replacing both springs is the best option. Most torsion springs are rated for 10,000 close/open cycles. If only one of your springs is broken, both springs are still recommended to be replaced. Considering that your second spring will break soon anyways, this added on fix is only going to cost you about $50 extra to assure that you don’t have to pay another service fee for a second visit.
Snap a locking pliers onto the torsion tube to lock it into place while you tighten the drums. Rotate the drum to wind the cable into the winding grooves. Pull the cable as tight as possible before tightening the setscrews. Leave the locking pliers in place and repeat the tightening procedure on the other side. You want equal tension on both sides. Otherwise, the door will open unevenly.
When cleaning the photo eye, you should take care not to scratch or damage the eye since it’s made of glass, similar to that of a camera lens. The photo eye itself is pretty small, only a few centimeters in diameter, but it can get dirty rather easily. To clean it, you’ll need a soft cloth and a mild, streak-free cleaner. Gently wipe away any dirt or residue that has built up on the eye and be careful not to oversaturate as excessive wetness can cause dirt to stick to the eye more quickly.
R-value describes the power of the insulation in your door. The higher the r-value, the stronger the insulation. Those doors will have better energy efficiency than doors that have a low r-value. Basic doors have an r-value of 0.0 with no insulation. The first step up gives you 1-3/8” insulation at a 6.5 rating. Next, a 1-3/8” thickness with Intellicore has a 12.9 r-value. The best option on the market is the 18.4 r-value, which has 2” Intellicore insulation.

Carter door: Garage doors in Florida come with extra bracing on the back and are wind-loaded to protect against hurricanes. The average with is 350 lbs. but some can weigh as much as 800 lbs.

However, if you lose power and use the disconnect switch, you’ll need to reattach it to use your garage door motor to open and close your door again. Open the door all the way and then reattach this hook. Then try opening or closing the door again with your transmitter, and you should be all set. It will be easiest to reattach this hook when your car is not in the garage, as you’ll need to place a step ladder underneath the motor to reach it.
7.3 Slide both torsion springs out above the top of the garage door toward the cable drums. Notice that there is only one bushing or bearing between the cones. Sometimes a single bearing is pressed into the bracket; other brackets have a single bearing or bushing that fits in either cone. Do not try to install a bushing or bearing in both of the stationary cones. You will risk breaking a cone. The purpose of the bushing is to keep the shaft from wearing against the spring anchor bracket. Only one bushing is needed to accomplish this.
CAUTION! Replacing garage door torsion springs is dangerous because the springs are under tension. If you do not use the right tools and follow safe procedures, you could lose hands, limbs or even your life. You could also damage property. We want your business, but not at the expense of your well being. Doing the job right is your responsibility. If you have any doubts about your ability to safely change your springs, we recommend you hire a professional to repair your garage door. Safety First! Then work.
In most cases, only one spring breaks or wears out at a time, and you can get away with replacing just the failed spring. But this is a little like replacing old car tires one at a time. You'll get the best performance if all the springs are new and have the same strength. Extension springs are replaced individually, making it more tempting to replace just one. With torsion springs, you have to disassemble everything to replace either spring, so it makes sense to swap out both springs during the repair.
