Unmatched or mismatched spring pair: You may find that you have a pair of springs that are different sizes. This mismatch may be a normal application, since the total torque on the torsion shaft is simply the sum of the torque contribution of each spring (indeed, very large doors can be lifted with 4 or more springs along the torsion shaft). The sum of the torque rates determine the lift; and dividing the torque among multiple springs does not change this. Some repair shops even apply mismatched pairs deliberately, since a few stock sizes of springs can be combined to fit a wider range of door weights than only matched pairs. For example, a technician may carry springs in increments of 20 lbs of lift, and when using pairs this allows a 20 lb increment in possible choices instead of 40 lb increments. Or, one spring from a pair may have broken and been replaced with a spring of equal torque rate but different size than the original.
We take the garage door installation process very seriously. The way a garage door is installed will impact every aspect of it for years to come. The noise level, ease of use, wear on other parts, appearance, and even out of pocket repair costs over the life of the garage door are all a direct result of how well the installation was performed. Call us today and you will see firsthand the A1 difference. Years from now you will be happy you chose A1!

Add the fact that a front-facing garage door can eat up almost 20% of your home’s front facade. With that much curb appeal at stake, a worn-out, beat-up garage door can be a real liability. No wonder that a big majority of homeowners responding to the “Report” gave a garage door replacement project a Joy Score of 9.4 — a rating based on those who said they were happy or satisfied with their remodeling, with 10 being the highest rating and 1 the lowest.

Note the left winding cone with red spray paint. This shpritz of paint is applied to create fear and doubt in the mind of the do-it-yourselfer. Sometimes it is a color code for the wire size (using a DASMA standard, red indicating 0.2253 inch diameter wire). Sometimes it indicates the winding direction: red may indicate right-hand winding, but don't rely on that; do you own independent analysis. Sometimes it is a manufacturer's private code for another dimension than wire size. This color code is for the installer's information when the spring is new; I would not depend on interpreting the color code properly on an old spring, since one can't be certain of a correct interpretation without documentation from the original supplier.


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.

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. It can cost up to $1,000 dollars to replace a steel two-car garage door and if it's made of wood it can cost you up to $5,000 dollars. Some customized doors can be as much as 20 - 30k.

Location, climate and building codes are just a few factors to consider when determining which type of garage door is right for your home. Depending on the region you live in, you may need to choose a wind load option for your garage door. Wind loaded garage doors help safeguard your home in high wind prone areas.

Once we understand the problem, we will fix the needed parts and make any adjustments to the door.

Widths - in addition to doors coming in a range of styles, they can be found as double-width and single-width styles. There are some serious considerations when opting for one over the other. For example, if a homeowner decides to use a single door that covers the entire opening of a two-car garage they will have to make serious structural modifications to the entry way;

Spring rate, torque, and lift: The spring rate K for these measurements is π*28.5*10^6 * (0.273)^4 / (32 * 140 * 1.72) = 64.5 IPPT. Applying 7.5 turns on this rate will yield a torque of 7.5 * 64.5 = 484 in-lb, which on the 4-inch drums (2-inch radius) yields a lift of (484 in*lbs)/(2 in) = 242 lbs. Again we find good agreement with the approximate door weight of 238 lbs.

The deluxe-model upsell trick: Don't you want the best? Don't you want to protect your family? Galvanized springs may be offered to you at extra expense as "longer lasting". Although bare springs (also called "oil tempered") can develop a light film of rust, the eventual failure is due to fatigue and not corrosion. The use of coated springs (whether galvanized, painted, powder-coated, or surface-converted) is mostly about appearance: the customer likes his new door to look shiny, and the customer doesn't like repair parts that show superficial rust from storage.

Direct Drive - Unlike chain- and belt-driven systems, where the motor remains stationary while moving a chain, a direct drive motor moves while the chain stays in place. Because of this, the only moving part is the gear the motor uses to move while lifting the door. To our knowledge, only one company makes direct drive garage door openers: Sommer. The company claims the motors are more efficient and quieter than any other type of opener. However, this is the most expensive type of opener we’ve found, costing around $286 on average.

Stress and lifetime: Calculating the maximal stress in the wire is useful for estimating the lifetime. Using the formula above, the bending stress S in the spring wire is 32*238/(π*0.2253^3) = 212 Kpsi. The spring index C is D/d = 2.23 / 0.225 = 9.88. The Wahl correction factor is Kw = (4C-1)/(4C-4) + 0.615/C = 1.15. The Wahl-corrected stress is Kw * S = 1.15 * 212 Kpsi = 244 Kpsi. This predicts about a 10,000-cycle lifetime, which is the standard "cheap spring" configuration originally installed. Note that while this stress is proportional to the torque being applied, it is also in proportion to the inverse third-power of the wire size. Thus slightly heavier wire sizes (and suitably adjusted D and/or L) radically improve the expected cycle lifetime of the spring.

Remember, not all garage door springs are alike. They are not one size fits all. If yours breaks, make a note of the brand and color code on the spring you need to replace. We'll get you the garage door opener parts you need, from seal kits to torsion and extension spring kits. Save money by replacing garage door hardware instead of replacing the whole unit.
