Our value pick is the Chamberlain PD76EV. It costs about $50 less than our top pick, but it has most of the higher-priced model’s advantages. The PD76EV has the same lift capacity, horsepower, lift system and automation compatibility. However, it doesn’t come with advanced features such as a backup power source, close timer and keyless entry pad. If you can live without those, this opener is a great choice.
We would definitely recommend Precision to anyone that needs garage door services! We were able to get a service appointment right away! Tom arrived and was very professional and courteous. He took the time to go over what repairs were needed and provided an estimate. He was ready to do the repairs right then and there and within a few hours, we had our garage door up and running like new! Thanks to Tom and Precision for a positive experience!
While a new coat of paint can go a long way in improving the look of your garage door, the truth is that door design has come a long way in the years since garages were first installed in homes. Not only are newer doors more in line with current fashion trends, but they are also better sized for today’s cars. A new, contemporary door is a great way to get an immediate boost on the value of your home.
We love the fact that you can connect the Chamberlain Whisper Drive with a phone app for long-distance control, as well as the fact that the door will secure itself if you forget to do so. As with any technology, there is a learning curve in which the kinks will need to be worked out. But overall, very few owners have anything bad to say about the Whisper Drive. One smartphone user expressed his satisfaction with the product by saying, “I can check if I've left the garage door open and close it from my office!”
In the photo, you can see an extra lag screw on the bottom of the plate, reinforcing weak anchoring from the original two screws (hidden behind the springs). This extra screw was applied by a professional garage door technician on a previous repair visit. I have since replaced the backing with a sound plywood panel anchored into the concrete door header. Since these bolts clamp all the opposing torsion to the wall, the attachment must be sturdy.

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.


Horsepower is another key factor when it comes to garage door openers. Look into ½ horsepower garage openers if you have standard aluminum doors. Oversized doors and one-piece doors may require 3/4, 1 or 1¼ horsepower garage door openers. Garage openers with higher horsepower use less effort to operate and minimize wear and tear on the motor. This is ideal if your garage doors act as the main entrance to your home.

Measure springs only when relaxed: Measurements must be taken on a relaxed spring because the winding adds significant overall length while reducing the coiled diameter. If you have a paired design, and one is broken and one is intact, then don't try to measure the length of the intact spring with the door down. A wound spring has 7 or 8 turns adding to the overall length, and will therefore be about 2 inches longer than when relaxed. Measure the lengths of the pieces of the broken spring, which will be unwound, and add them together. As a check, one can measure the length of the intact spring after it is unwound in the procedure to follow below. Be sure also to observe whether the springs are originally of equal sizes, because it is quite possible that they are not.
The electric overhead garage door opener was invented by C.G. Johnson in 1926 in Hartford City, Indiana.[1] Electric Garage Door openers did not become popular until Era Meter Company of Chicago offered one after World War II where the overhead garage door could be opened via a key pad located on a post at the end of the driveway or a switch inside the garage.[2]

"I couldn't be happier, they solved a year long problem we had that a competing company of theirs (who installed the garage on our new home) couldn't fix! I feel Ric and Randy both (who have fixed a garage at my old house and my new house) take a lot of pride in their work, they are ethical and operate with integrity. I only want to work with Precision Garage Door from now on. I'd recommend them to anyone and everyone! ”
The open-ended work-order trick: You may be very surprised if you allow work to proceed without signing a work order with a specified price. Or, you may sign a work order, and think you're protected against open-ended wallet-reaching, only to find a much higher price due at the finish than you expected, because you signed a "parts as needed" order that got loaded up with a long list of parts (that likely were still in serviceable condition). You might have been quoted a price, but then get a bill for that price plus a lot more added for the "service call" and the "parts", and be told the quote was just for the labor. While this is the normal way of abusing your finances down at the hospital, you shouldn't agree to it for a garage door service call. These guys are not doctors.

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.

Current data from real estate firms throughout the country show that replacing the garage door raises the value of a home by an average of $2,810, according to Remodeling Magazine's report. Based on the average cost of $3,304, this means that replacing a garage door is expected to return 85 percent of the job’s cost, nationally. When replacing a garage door in the Western U.S., however, the return is predicted to be 110.8 percent of your investment.


A spring design manual, also called a rate book, gives tables that relate the torque constant ("rate") and maximum turns for springs of given wire size, diameter, and length. For example, a typical page in a rate book would show a table for a given wire size and inside diameter, the maximum inch-pounds (MIP) of torque available for a standard lifetime of 10,000 cycles in that size, the weight of the spring per linear inch, and the rates of the spring (as IPPT, inch-pounds per turn) for each of various lengths. From these figures one can calculate the lifting capacity, substitutions, conversions, and cycle life upgrades for a door of given weight and drum geometry. The weight-lifting capacity of a given spring is calculated based on its torque constant (IPPT, or inch-pounds per turn), which is the rotational version of the spring constant that characterizes the spring. The IPPT constant is found from tables giving IPPT for given spring dimensions (wire-size/diameter/length). The same tables may indicate the maximum number of turns for various expected lifetimes in cycles. The torque required to balance a given door can be calculated from the weight of the door times the moment arm of the drums (as we do below under "Calculating the Forces We Will Be Handling"). The ultimate torque of the spring in the fully-wound condition is the number of turns (when fully-wound) times the IPPT constant. Choosing a spring to balance the door then simply requires matching the ultimate torque of the spring to the balancing torque.
When ordering springs, be aware that a number of different sizes of springs will make proper replacements, not just the specific size being replaced. The wire size, winding diameter, and length can be traded off to make springs of varied geometry but equivalent torque characteristics. This will also affect the expected lifetime (in cycles) for the spring(s). Since the critical specification for a replacement is the weight it is designed to bear, not the sizes per se, there are likely several stock sizes that replace a given old spring. The spring distributor's inventory may happen to offer only a different size with an equivalent weight-bearing specification. One has to judge whether to trust the advice of the seller in such situations. The seller should have the data to know what substitutions are proper.
