Today's garage doors come with those door sensors, and if anything is in the path of the door the sensor detects it and raises the door back to the open position. These precautions are important for families with young children or pets. Even if you don't have a mini me or furry friend running around your yard, it's a good idea to have a garage door that is safe for you, your guests and your belongings. 
Those who benefit from this anti-competitive behavior have many excuses for it. They claim that the product is too dangerous and infrequently needed for the public to purchase directly. They say the job is hazardous and requires techniques and tools with which the amateur will rarely practice, which is true. They write me in anger saying I don't understand how expensive it is to put a truck on the road with a technician and parts and salary and benefits and insurance and advertising and every other common business expense. They say it will take the homeowner hours of effort to do this safely and correctly, while they can do it in a fraction of that time and at a price that isn't worth the effort to save. But should they set themselves up as the judge of what you can and cannot do? Of what is an economical use of your time? Imposing minimum order quantities or charging retail prices for small orders is legitimate; inquiring into the purchaser's background is not.

The wire size and winding direction are easily discovered and proved, as I will explain below. You absolutely must know and understand the critical measurements of your old springs to order replacements. This assumes that the old springs were the correct to begin with; it is not uncommon to have incorrectly sized springs on a door due to a previous sloppy installation, or a significant change in weight of the door.

A torsion spring counterbalance system consists of one or two tightly wound up springs on a steel shaft with cable drums at both ends. The entire apparatus mounts on the header wall above the garage door and has three supports: a center bearing plate with a steel or nylon bearing and two end bearing plates at both ends. The springs themselves consist of the steel wire with a stationary cone at one end and a winding cone at the other end. The stationary cone is attached to the center bearing plate. The winding cone consists of holes every 90 degrees for winding the springs and two set screws to secure the springs to the shaft. Steel counterbalance cables run from the roller brackets at the bottom corners of the door to a notch in the cable drums. When the door is raised, the springs unwind and the stored tension lifts the door by turning the shaft, thus turning the cable drums, wrapping the cables around the grooves on the cable drums. When the door is lowered, the cables unwrap from the drums and the springs are rewound to full tension.[7]
A garage door is a large door on a garage that opens either manually or by an electric motor (a garage door opener). Garage doors are frequently large enough to accommodate automobiles and other vehicles. Small garage doors may be made in a single panel that tilts up and back across the garage ceiling. Larger doors are usually made in several jointed panels that roll up on tracks across the garage ceiling, or into a roll above the doorway. The operating mechanism is spring-loaded or counterbalanced to offset the weight of the door and reduce human or motor effort required to operate the door. Less commonly, some garage doors slide or swing horizontally. Doors are made of wood, metal, or fiberglass, and may be insulated to prevent heat loss. Warehouses, bus garages and locomotive sheds have larger versions.

I could not be happier with the service from Precision, and Tom, especially. About a year and a half ago I called to have my garage door that was sticking, repaired. Tom came out same day and replaced, adjusted, serviced all moving parts and got it going smoothly. He has since come out within hours of a call to adjust and keep (what might not be the best) door, (originally installed by someone else), operating well. I recommend Precision and Tom with complete confidence.

Insulation, which increases energy efficiency and can help to lower utility bills, is crucial when a garage door is attached to the home. In this case, doors with high R-values are preferred. This means it has insulation that can keep the heat in. The higher the R-value, the better insulated your garage will be against outside noise and cold and hot air.


If return on investment is a priority and you don’t live in the West, your best strategy may be to buy a low- to moderately-priced door that significantly improves the look of your home. Consider adding an automatic garage door opener at the same time. The beauty of a new door and the convenience of an automatic opener are sure to be a winning combination.

Yet another professional wrote me to say that the red paint on certain components of these assemblies is an "industry standard" that signals, "Danger! Part under hazardous tension." Other items under tension like the bolts on the cable attachment plate on the door should therefore also be painted red. If so, then this is a new, ambiguous, unreliable, and little-publicized standard, because none of my old hardware shows it, red paint also means other things, and searching the Web does not readily turn up references to this practice.
Depending on the design, you can know in advance how many turns are going to have to be unwound. Lifting a 7-foot door by winding a cable on a 4-inch diameter (about 1 foot circumference) drum requires about 7 turns, plus one extra turn to maintain cable tension at the top-of-travel. Maintaining tension at the top-of-travel is critical; without it the cable will jump off the drum, requiring a serious repair.
Measurements: With the door in the down position, I measure a wire size of 0.273 inches, outside diameter of 2.0 inches, and overall length of 41.5 inches. Relaxing the spring shortens the length by about 7.5 coils of wire, so to estimate the relaxed length, we deduct the wire diamter of 0.273 inches times 7.5 from the 41.5 inch wound length, yielding an estimated relaxed length of 39.5 inches. The mean coil diameter is 2.0 - 0.273, or 1.73 inches. Perhaps this was actually a 40-inch-long spring with a 1.5 ID, 1.75 mean diameter, and 2.0 OD, but let's continue on calculating with the actually observed sizes. The number of coils in the relaxed spring is the relaxed length of 39.5 inches divided by the wire size of 0.273 inches, or about 145 coils. Deducting about 5 dead coils at the ends yields 140 active coils.
Most wood doors are sectional roll-up doors, though a swing-up wood door that’s meant to be painted can be affordably built in the driveway from a wood framework and plywood. Custom wood doors are typically made of durable softwoods such as Douglas fir, cedar, redwood or cypress, or from hardwoods such as oak or mahogany. Appearance-grade hardwoods are relatively expensive.
Since we're using an 18-inch (1.5 feet) winding lever to wind each spring up to 29 foot-pounds, we must apply a maximum tangential force to the end of the winding lever of about 20 pounds. Later we'll see that the actual weight of this rather dense door is 238 pounds, implying a maximum tangential force on the winding levers of only about 13 pounds!
Next, the torsion shaft is reassembled with the new springs, the drums repositioned loosely on the shaft, this whole assembly slid back into the end bearings, and the drum set-screws tightened down. I tightened the set-screws about 1/2 or 3/4 of a turn after contact with the shaft, which provides a good grip, but does not distort the shaft. The drums can be set on their old positions, if they were correctly installed, which is snug up against the end bearings to remove any longitudinal play in the torsion shaft. Now the lift cable can be reattached to the drums, and a slight temporary torque applied to the shaft to keep the cable taut while the first spring is wound. This temporary torque is conveniently applied with a pair of locking pliers clamped on the shaft, positioned such that they hold the torque by pressing lightly against the wall above the door, before you start the spring winding, The locking pliers stay on the torsion shaft until you have finished the spring winding locked down the spring cone(s) with the setscrew(s), and removed the winding bars. Then you simply remove them with the release on the wrench handle. I feel that any job that doesn't require a trick manipulation with either locking pliers or duct tape (or in the ultimate case, both!) is just too boring. My trusty pliers look a trifle rusty ever since I used them to clamp something on my outdoor TV antenna "temporarily" and left them out in the weather for, oh, several years. The white stuff on the drum is paint overspray from the original painting of the garage interior.
It is precisely on those coldest days of the year when you most need and appreciate the convenience of opening and closing your garage door quickly. Sadly, those also happen to be the kinds of days when cold and moisture combine to make this difficult. Garage doors can and do freeze to the garage floor. Sometimes it is a minor icy connection between the two that can be broken when you hit the opener button.
Had a quick response to my call. thought I might have to wait a couple of days to coordinate their schedule and mine. To my surprise I received service in one and one half hours. Not only that but there was no sales call, technician Mike was fully prepared to give me a quote and complete the work as his vehicle carried everything needed. He very efficiently completed the work and cleaned up after I selected from the options. He replaced the springs all rollers and made needed adjustments expeditiously. I would recommend this firm to anyone needing garage door repairs.read more
The "safety issue" trick: Another tip-off is the use of language like "safety issue". This is meant to trump any objections you might have to a costly repair bill. Don't be manipulated by the suggestion that you are risking disaster if you don't buy something expensive. Even if you think the risk is genuine, get another estimate, and tell the second repairman you are skeptical; every technician loves to prove the competition made a mistake.
Note that I am measuring a spring that is fully relaxed because it is broken!. The length of the relaxed, unbroken spring is the specification of interest. It is harder to measure unbroken springs on an intact door because the springs should not fully unwind, even at the top-of-travel. If you can't be certain of the spring diameter from indications on the cones, then you have to go through an unwinding procedure to relax them fully for measurement, or perhaps reckon the size from measuring the somewhat smaller diameter at the nearly unwound condition when the door is at its top-of-travel (although one should not attempt to raise a door with a broken spring).

“Especially on houses where the garage is front and center, the garage door absolutely has to look good,” says Casey McGrath, a real estate practitioner in Kitsap County, Wash. And it has to operate smoothly: Americans use the garage more than any other entry to the house, including the front door, according to a survey commissioned by window and door manufacturer JELD-WEN.

Having a mismatched pair makes it difficult to specify the correct matched-pair replacements. To obtain replacement springs for a mismatched pair, you can either specify the same odd pair, try to calculate the equivalent matched pair sizes, or (this is the best method:) measure an accurate door weight and calculate the right spring size(s) "from scratch". The spring seller should be able to do the calculations from your accurate measurements of weight, height, and drum size; or you can attempt the calculations yourself using my engineering formulas below.
Not only was the upward-lifting garage door and the electric garage door opener invented by Overhead Door Corporation’s founder C.G Johnson in the 1920s, but we also have a tradition in excellence for garage door repair, service and maintenance. Even with the most reliable products problems can arise and when they do it’s important to know who to contact to fix these issues while providing solutions to prevent future complications.
Looking for another budget option? This one, also from Chamberlain, is a good choice. With a powerful ½ horsepower motor, it’s reliable and rugged, especially paired with its industrial strength chain drive. The 100-watt bulb gives you some overhead light that guides you into your home from your car safely. It also comes with a pre-programmed, one-button remote that can be used over a long range. Plus, there are safety sensors that project an invisible beam helping to prevent the door closing on people or objects. And when the door is closed, you can rest assured it’ll stay closed and locked thanks to its Patented Security + 2.0 rolling code technology and PosiLock anti-theft protection.

Trading diameter for length: Observe that in the spring rate formula in the table above, factors D (diameter of coils) and N (number of coils) appear together in the denominator of the spring rate formula. Algebraically, given equal wire sizes, this means that the product of the coil diameter and overall length produces the spring torque, not the diameter or length alone. Physically, this means that you can trade off torsion spring coil diameter versus overall length in inverse proportions to maintain the same torque rate. Trade-off example: A spring with 2-inch diameter coils that is 36 inches long equals a 1.5-inch diameter spring that is 48 inches long, because the product in both cases is 72 (inches squared). This assumes that wire size is equal in the trade-off, and that you have not counted dead coils in the length. Service technicians use this principle to make quick substitutions for what's on their truck versus what you need. But if you understand this, you're ahead of many technicians who don't know this trick. Maybe now you can educate the next one you hire.
Called for an appointment and was surprised that I could have a tech come the same day. Matt arrived ahead of schedule, inspected the garage door and gave me a tune up to get things working properly again. He explained what would need to be done in the future, and the cost. I will certainly call them when the time comes to get that work done.read more
Recently another type of opener, known as the jackshaft opener, has become more popular. This style of opener was used frequently on commercial doors but in recent years has been adapted for residential use. This style of opener consists of a motor that attaches to the side of the torsion rod and moves the door up and down by simply spinning the rod. These openers need a few extra components to function safely for residential use. These include a cable tension monitor, to detect when a cable is broken, and a separate locking mechanism to lock the door when it is fully closed. These have the advantage that they free up ceiling space that an ordinary opener and rail would occupy. These also have the disadvantage that the door must have a torsion rod to attach the motor to.
