Before setting the last panel in the tracks, set the power unit on the actual frame and slide it in the ends. Hardened screws are used to attach the center bracket (Image 1). They are a different type screw — they are tougher and will last a lot longer. Make sure the bracket is level (to the eye) when installed and leave the bracket a little loose so adjustments can be made. Fasten down all the hinges (Image 2).
Looking for something powerful but don’t want it to be too loud? This garage door opener from Chamberlain is a great option. Featuring an exclusive Motor Vibration Isolation System which eliminates vibration for reduced noise, this is a good choice especially you have an attached garage with rooms above the space. It also has MyQ enabled technology that allows you to monitor and control the opener via your smartphone with an extra purchase of the product. You can set the opener’s timer to close the door one, five or 10 minutes if you forget, and it has sensors to make sure it won’t close if something is in its path. It comes with a lifetime motor, lifetime belt, five-year parts, and one-year accessories warranty.
Manufacturers and distributors of torsion springs believe they are better off not retailing their product directly to the public. They believe they are maintaining higher prices for their product by restricting sales "to the trade." One brochure for parts even flatly stated, "We do not sell to the end user. We protect our dealers," which would seem to be prima facie evidence of an illegal restraint-of-trade scheme. But this is an old story which is true of virtually every product and service, going back to medieval guilds and before.
Beware of improprer prior installations: Sometimes the existing door installation is not correct, and the old springs should not be used as a specification for replacements. For example, the old springs might have been replaced with incorrect sizes because the last repairman didn't have the right one on his truck. If your door has never worked quite right, something like this might be the cause. To correct this, you must use the weight of the door to specify the spring, either from a spring rate manual giving spring torque constants, or from the formulas below.

The garage door opener traditionally has been a simple device. And it still is for the most part. But as with a lot of household items, technological advances are finding their way into garage door opener hardware. There are quite a few cool features in modern garage door openers, some of which are things you never knew you needed to automate the process of opening and closing a garage door.

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.


Garage door repair is a specialized job, which is typically handled by a garage door repair service. Professional garage door repair technicians can test or repair a garage door system and fix cosmetic blemishes on doors. Common requests include help with jammed or inoperable doors, slow or erratic doors, unusual sounds, dents or scrapes on the door, and general system testing. Garage door repair professionals can work on single-car, double-car and RV-size garage doors.

Since their invention in the 1920s, electric garage door openers have come a long way. Garage door openers work by using a trolley connected to an arm that attaches to the top of the garage door and slides back and forth on a track, which opens and closes the garage door. When operating the motor, a chain or belt turns and pulls the trolley along the track. A good garage door opener will have a horsepower of 1/2 HP, 3/4 HP, or 1-1/4 HP. Garage door openers have the ability to open and close a limited number of times in power outage emergencies. Security is something else to consider when purchasing an opener. It's helpful to have sensors that will stop the operation of the garage door when a person, vehicle, or other obstacle is in the way.
Most situations allow you to replace spring(s) without removing the assembly from the wall, if there is enough clearance in the surrounding garage structure at the ends of shafts. By unbolting the end bearing plates and removing the drums, you can run the springs down to the ends of the shaft to remove and replace the springs. This avoids the balancing act of holding a long, wobbly, heavy shaft while climbing up and down a ladder. This is how the professionals get the job done in a few minutes.
One can overwind the springs slightly, up to about 8 turns on a standard residential door (that is, 1/2 or 3/4 extra turns), to compensate for undersized or fatigued springs, or increased door weight from painting or humidity, but this results in more stress on the springs and therefore decreased lifetime. If the door is too heavy for that slight tweak, then different springs are needed.
One way to determine if you need a new garage door is to check the seal at the bottom of your door. If you see a gap, then perhaps you need to think about replacing your door. Or perhaps not. The seal, often called a rubber bottom, can be replaced. If the lower section is showing rot, then it may be possible to replace just that section. To find out if your garage door needs to be replaced or just needs a little TLC, call us. We'll help you explore the alternatives that are best for you.
The majority of those who have purchased this product have been happy with it, saying it’s extremely quiet and comes with a great lifetime warranty. Some of the more critical reviews had to do with the remote not working well and other minor malfunctions. (A few quick tips can help you fix any common garage door opener problems.) However, most were satisfied with the product and would recommend it to others.

Smartphone Control: Many newer garage door openers allow you to connect the device to your home's Wi-Fi network, according to RW Garage Doors. You then can open and close the door through a smartphone app. In fact, many of these apps will give you an alert on the smartphone when the garage door is open for a certain period. Some opener models even can connect to your existing Smart Home system, incorporating all your appliances on one system.
Of course, the best garage door openers offer much more than weather protection. They are quick and convenient when leaving or returning home. They can secure what might otherwise be a weak point of home security. Some can even alert you at work if your garage doors aren't closed properly. The challenge you face is finding the right one – this isn’t a product you can simply try out and return until you find the best fit for your situation.

The torsion shaft with lift drums on the ends is above the door. The standard residential door shaft is a 1-inch outside diameter hollow steel tube. The inside diameters of the bearings, drums, and winding cones are sized to loosely fit that 1-inch diameter shaft. At the center is a bearing plate, on either side of which are the torsion springs, or in some cases just one larger spring. The spring pictured on the left in the photo is broken about 1/4 of the way in from its left end. The black shaft with dangling rope and door bracket is the track for the electric opener.
You can expect to pay between $130 and $350 for a garage door opener, with most models costing an average of $200. The most expensive openers usually include extra accessories and smartphone controls, though most openers can work with a smartphone if you buy a Wi-Fi adapter such as MyQ. The types of garage door openers in increasing order of average cost are as follows: chain, belt, screw and direct drive.

Torsion springs are devices that lift most of the weight of a garage door so that the door can be opened manually or by an electric opener. The torsion principle is applied via an efficient and economical apparatus consisting of a torsion shaft under spring torsion, which turns lift drums, which wind cables attached to the door near the bottom. All of this apparatus is mounted over the top of the door. The energy stored is sufficient, in an uncontrolled release, to break things, hurt you, or perhaps even kill you. The same could be said of jacking up your car to change a tire, or mowing your lawn, or raising children, so it is not crazy to want to do this yourself.
