Charlotte, NC is  a bustling market for new homes, business construction and restoring old homes.  Charlotte’s real estate market is booming. Our company has been a part of this growth by installing and repairing over 50,000 garage doors since 2001. In this span of time, we have had no issues with the county inspections office. We have done this by making sure that our clients buy the right doors, and have permits in place, if needed. Keep in mind that we are not general contractors, so we do not supply permits, but we provide the information and resources for you to easily apply for permits if one is needed for your project.
The winding technique is simply to (un)wind as far as one rod will go, where it is pressed against the top of the door, or nearly so, by the unwinding torsion. You insert the other rod in the next socket, remove the first rod, and continue. At any point you can stop and rest by leaving the active rod pressed against the door, where it will be held by the unwinding force. I would make a quarter-turn increment that way, and let go for a moment to collect my attention for the next increment, almost in a quiet, meditative alertness. While you can go from one quarter-turn and rod-swap to the next continually without letting go, working fast against the steady tension seemed to invite a kind of shakiness in my arms that was a bit unsettling. It isn't that there is much physical exertion, it is more that the tension is unrelenting, like peering over a precipice.
Not interested in paying for maintenance on an outdated and failing system? Our installation services mean that you can have a brand new, high quality garage door installed in place of your existing model. Because we carry such a diverse range of products from the most industry-respected manufacturers, we’re sure to have a model that fits your needs and budget.
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.

All measurements should be in feet and inches. Step 1, measure across the existing door or desired space for the width, then up and down for the height. The rough opening of your space should be the same size as the door. Step 2, measure the sideroom, which is the space beside your door. Measure the width of the left side, and then the width of the right side. Step 3, measure the space above the door, which is called the headroom. Measure the height of the distance between the top of the door opening and the ceiling. Step 4, measure the ceiling, which is called the backroom. You’ll need to measure the distance of the garage door opening toward the back wall of your garage. You should have 6 total measurements in all once you’ve finished measuring the space. Keep in mind that having an automatic garage door opener installed might call for additional backroom or ceiling space.

The Certified Technician, Rey Lopez, was competent, professional, polite, and willing to work. He quickly removed the old door and installed the new one. He then explained the vast differences between what we originally had and what we'd just purchased (stronger spring/tension rates; increased viability of door opening/closing life; beefier hardware; plastic vs. nylon rollers; stronger door reinforcement). Ray performed with alacrity his tasks and then demonstrated the quiet, solid way the door retracted--no banging after the initial rise from the ground. Finally, his attention to detail was so precise that he enabled another remote controlling all three doors, plus he capped some frayed wires, thus solving the problem of why the door opened intermittently. I would rate him a "6" on a scale of "1-5", meaning he went above and beyond our expectations. His "can do" attitude, coupled with the deference he showed, will take him a long, long way. May HaShem richly bless him in his endeavors!read more
Precision: I got a call from my wife instructing me to come home right away - my neighbors daughter had backed our truck thru our double garage door. When I arrived home there was a Precision truck in my driveway, wow you're fast! The door was pretty badly damaged, unsecure and could've come down more. Your technician Dannie Ray told us no touch, extremely dangerous". Since our door is out of production Dannie started calling and found a door in Tacoma, and Dannie takes off for Tacoma. He calls me at about 3:00 pm. and tells me he's about 1/2 hour away and he's coming back to install both new doors. Second wow! About 1/2 hour later here comes Dannie with 2 new doors and proceeds to go about his business. My wife and I had to leave we asked Dannie if he was good, he said no problem. We arrived home around 10 pm to brand new doors that work and look terrific. As a business owner and full time Realtor I appreciate it when I see such outstanding service and concern that truly is "above and beyond". Now if I or one of my clients needs anything to do with a garage door I now have you on speed dial. Again, Thanks for such a great experience in a difficult moment. Thanks again Dannie, come by anytime!
Prices, like the garage doors themselves, run the gamut. You can pay as little as $400 for a door that you install yourself, or several thousand dollars for a high-end premium door that includes all the bells and whistles, including installation. A mid-range, 16-by-7-foot door will typically cost from $750 to $1,500, installed. Premium insulated steel doors run from $750 to $3,500. According to Remodeling Magazine’s 2017 Cost vs. Value report, the average national cost of a garage door replacement is $3,304.

There’s another reason new doors are superior to old ones: energy efficiency. Keep in mind, garage doors are large, and when they open, they let a lot of outside air into your home. While you may have significant insulation separating your garage from the rest of your home, eventually that temperature differential will start to influence your energy bills.

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!
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.
Once the shaft, springs, and center bearing plate come down and lay on the floor, the old springs should be easy to get off and new ones slid on and assembled. Two bolts hold the center cones to the center bearing plate. The bearing on the center plate can be oiled while it is exposed from having the springs off. At this point it is a relief to be working with inert parts while standing on the floor rather than energized parts while up on the ladder. You might think it would save a little time to replace the spring with the shaft left up on the wall, but I found it was easier and safer to lower the works down to the garage floor first.

Permits must be applied for when you are building a new home or structure. This permit will cover the building of the structure and cover the inspection for your garage door. The inspection process for a new door is pretty simple. The county will want to make sure that you have a garage door installed that meets local wind rating standards. In Mecklenburg County, that standard is 90 mph. That means that your door must be rigid enough to withstand 3 second gust by winds of up to 90 miles per hour.


Hello Scott and thank you for the very nice 5 star review. John, our Tech, will be very happy too. I will review our on-phone quoting system after listening to your call and see if we can get better at more accurate pricing. It is just so tough to know exactly what is going on at the site and the extent of the repair until we set eyes on it. We will try to get better at it...I promise. Thanks again.
Most garage door openers are pretty expensive. So if you need an opener on a budget, the Genie 1035-V (also known as the Genie Chain Drive 500) gives you that desirable low price point. It doesn't have a lot of high-end tech features, nor will it manage heavy garage doors, but it does the basic work of raising and lowering the garage door perfectly well.
The prior clamping of the set-screws tends to have pressed a dimple into the hollow shaft and to have distorted the shaft's roundness into an eccentric shape. While releasing the set-screws, I was careful to loosen them enough to let the cone swing around any such distortions. I was also careful to observe any binding of the old cones on the eccentricity or burring on the shaft. The fit of the cone on the shaft is supposed to be loose enough to avoid binding, but if it were to occur one would have to be careful not to assume the spring was unwound when in fact the cone was just stuck on the shaft. If I had a stuck cone that I could not unwind with a little extra force, then I would have called in a technician to deal with it. In the worst case, I suppose the spring must be deliberately broken with some hazard, thus releasing it for a forceful disassembly, and the shaft and some other parts replaced. But this is an unlikely situation and in this case was not necessary.
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.
An intermediate stage of the garage door opener market eliminated the DIP switches and used remotes preprogrammed to one out of roughly 3.5 billion unique codes. The receiver would maintain a security list of remotes to which it would respond; the user could easily add the unique remote's code to the list by pressing a button on the garage door opener while activating the remote control. The large number of codes made the brute force try-all-possible-digital-codes attacks infeasible, but the systems were still vulnerable to code grabbers. For user convenience, these systems were also backward compatible with the older DIP switch remote codes, but adding an old technology remote to the security list made the garage door opener vulnerable to a brute force attack to find the DIP switch code. The larger code space approach was an improvement over the fixed DIP switch codes, but was still vulnerable to the replay attack.
Luckily, there is a bit of science to questions of garage door repair and replacement. That’s why we’ve put together this guide on when to replace a garage door. We’ll prepare you to compare repair vs replacement garage door costs. We’ll discuss the ways in which repairs are the most affordable option while also exploring those moments when replacement will in the end provide you with more value added.

Spring index lower limit: DASMA standard 102-2004 provides a lower limit of 6 for the spring index, which is symbol C in our formulas above (section 9.3). Other interesting items in this standard include an upper limit for how much the door sags when raised (no more than 1/120 of its width, section 9.2.1), that each of the two bottom brackets should sustain twice the door assembly's weight (section 9.2.2) for a total safety factor of about 4, and that the lift cables should provide a safety factor of 5.

In 1993, U.S. law dictated that all garage doors must have a reverse mechanism to prevent the door closing on persons or property. In most models, an infrared beam running across the garage opening acts like a tripwire. Break the beam and the door rises again. This is a legal requirement that ensures the garage door cannot trap people or animals. It's also useful in avoiding accidental damage to your car, bikes left in the way, or other property.

Through our garage door configurator by Clopay, you can design, visualize and purchase a new Clopay garage door. Upload a photo of your home and then browse the configurator to see which style works for you. Choose from a variety of designs, textures, colors, finishes, window options and decorative hardware. You’re able to easily and quickly see the transformation, and then make it a reality.
The optician's trick: The serviceman looks over your door with lots of scowling, chin-scratching, and tsk-tsking. You ask, "how much?" He replies with the fair price. If you don't flinch at that price, he says, "for the parts", while quoting a large additional cost for the labor. If you still don't flinch, he adds, "each," while pointing back and forth to your pair of springs. (I hope none of you service people are reading this!) I call this the "optician's trick" after the old vaudeville joke about lenses, frames, and left/right.

Once the springs are relaxed and loose on the torsion shaft, the lift drums lose their tension on the lift cable, and the cable comes loose. The end of the cable is terminated by a press sleeve, which locks into a ramp on the drum. Different drum styles have a bolt or other method to fix the cable end to the drum. These steel cables are springy and won't stay in place without tension. If my pre-inspection had showed that these cables were worn or frayed, then I would have ordered proper replacements ahead of time from the spring distributor, since this is the opportunity to replace them. Standard hardware-store cable and fittings are not appropriate.

Repair Sagging Garage Doors – As doors and homes age, they can shift and move and sometimes this results in a garage door that needs to be realigned or reinforced. We will send a technician to your home to adjust the doors and to inspect the entire opening to make sure the door isn’t damaged. Once we understand the problem, we will fix the needed parts and make any adjustments to the door.

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.
These springs weighed in at just over 9 pounds each, including the winding cones. They are covered with a light film of oil, and at this point the job starts to get messy. The manufacturer has painted them with a "225B24" part number, which no doubt indicates the 0.2253 inch wire size, 24 inches long. Perhaps the "B" indicates the 2-inch inside diameter. Both the left- and right-hand springs have this same number on them.
Many garage door opener remote controls use fixed-code encoding which use DIP switches or soldering to do the address pins coding process, and they usually use pt2262/pt2272 or compatible ICs. For these fixed-code garage door opener remotes, one can easily clone the existing remote using a self-learning remote control duplicator (copy remote) which can make a copy of the remote using face-to-face copying.

Scott did an amazing job. Your customer service team is excellent. I emailed late on Thanksgiving night my request for service. Your team called my house within 30 minutes and set up an appointment for the following morning. Scott came out and was great. I had purchased the lifetime warranty package with Precision before, and your team delivered. I highly recommend anyone getting a repair to purchase the lifetime warranty package since your team stands behind your product. Rarely do I write reviews - but am happy to share great information on great companies. Thanks for the great service!

This work is risky, but the risk is comparable to doing your own car repairs, or climbing on the roof of your house to clean your gutters. These are dangerous things that many people can do safely, but that safety depends on intelligent understanding and application of proper techniques. Professional door repair technicians, who are fully knowledgable, skilled, and experienced, report that they nevertheless are injured from time to time, despite their best efforts. Coldly evaluate your abilities and motivations, to judge whether you can manage the risks of this work for the benefit of the money and time you might save.
Now 13 pounds of force must be respected when backed by many hundreds of foot-pounds of stored energy, waiting to be released. Holding this torque is equivalent to stalling a 3 horsepower DC motor. But holding and turning these handles does not require extraordinary human strength. Note that this maximum tangential force depends only on the weight of the door, and the radius of the drums, and is divided by the number of springs (some designs have only one longer spring, as mine did originally, instead of two shorter ones). Higher or lower lift distances imply more or less turns to wind the spring (and thus a different spring geometry), but not more force on each turn.
The right side of the photo shows the center bearing plate where the stationary cones attach with two bolts. Some doors may have only one spring rather than two equal ones as shown here (indeed, old marks on the shaft show that this door originally had one spring about twice as long on one side). Above the center bearing plate is the bracket and track from the electric opener.
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.
Using your drill, add tension to the torsion spring. This system uses a single spring for a double door, but many manufacturers use two springs for a double door. The painted line on the spring acts as a gauge for the number of turns you put on the spring. To keep the bar from turning while you’re adding tension, attach a locking pliers to the bar on both ends of the spring. Apply lubricant for garage doors to the spring.
Insulation increases the efficiency of your door and can lower your electric will. You need R-value garage doors. These type of doors keep out hot and cold air and also provide a sound barrier between the outside and your garage. Insulated doors use polyurethane or polystyrene foam as insulation inside the door.

An entry may be the central tremendous moving piece of your home. It obliges routine upkeep practices to verify that it serves you for long, and chances of incidents are diminished. You will unquestionably take note that there are things you can do without anyone else to guarantee that it stays fit as a fiddle. However, when there is an issue, it is always recommended to call Local Garage Door Repair, Inc . When you select to do it independent from anyone else, without the obliged experience, you may end up exacerbating the issue or doing harm yourself and people around you.
I was careful not to assume that the previous installation correctly oriented the right- and left-hand springs on the correct sides of the center bearing plate. They could have been installed backwards by an incompetent installer, resulting in them having been wound looser (larger diameter coil) instead of tighter (smaller diameter coil) than when in their relaxed state, and if so I would have corrected them on the new installation. The proper orientation of the springs applies their reaction torque from tighter winding such that it turns the drums to lift the door. Verifying this is a rather simple exercise in mechanical visualization, but does require some care to be certain of correctness. If you were to install the springs backwards, and then start to wind them in the wrong direction, then the torsion bar will start winding the drums backwards, and not holding against the vise pliers, which should be obvious to inspection. Winding a spring backwards also tends to screw the spring off the cones; this error cannot proceed too far before the spring slips off the cones.
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.

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.

I repeat my caution about the uncertainty of interpreting color codes. A professional installer reading this page emailed me to say that the red color indicates the springs are right-hand windings, not the DASMA color code for the wire size. But this photo shows both a right- and a left-hand spring, and both have the red paint on the cones and set-screws. I conclude it is prudent to make your own measurements and analysis. Do not rely on the colors on old installations. The only time I would respect them would be on new parts that carried documentation giving the code.
My garage door broke on a Saturday night as I was getting ready to leave for a holiday party. Kelvin was here within 30 minutes. He reviewed everything with me that was happening with my door. He gave me the estimates of what was immediately needed to be done in order for my door to raise and then what I will need to have done very soon. I could see all the problems he pointed out to me and I decided to have everything done. He completed everything that night. I was very satisfied with Kelvin’s professionalism and the work he did. Thank you again.
The lucky-for-you-I-found-another-problem trick: Another trick is to suggest your automatic opener was damaged (or "compromised") by the additional load or shock presented by the failure of the spring(s). The plastic worm gear used in the most common openers (see above) wears normally over the years and tends to leave a lot of debris inside the opener housing. Removing the opener cover reveals a lot of plastic shavings that may be cited as "evidence" you need a new opener, when the gears are actually still serviceable. Nevertheless, you may have indeed worn out the gear if you repeatedly cycled the door with the opener despite having broken springs, which is possible if you have a very lightweight door.

Dodging a falling door:: Reversing this equation gives us x=gt^2/2 as the fallen distance x for a given time t. How much time would you have to dodge a falling door if the spring were to suddenly break at the top of travel? Let us assume you are 5.5 feet tall, so the door will hit your head after falling 2 feet from its 7.5 foot fully-raised height. This 2-foot fall takes sqrt(2*2/32.2) = 0.35 seconds (350 milliseconds). The quickest human response time is about 200 milliseconds, so even if you are alert to the hazard, this leaves you only about 150 milliseconds to accelerate and move your noggin out of the way. If you are an Olympic gold medalist in the 100 meter dash, you can accelerate (horizontally) about 10 feet/second^2, and your 150 milliseconds of wide-eyed panic will move you all of 10*0.15^2/2 = 0.11 foot = 1.35 inch.
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.
Mechanical garage door openers can pull or push a garage door with enough force to injure or kill people and pets if they become trapped. All modern openers are equipped with “force settings” that make the door reverse if it encounters too much resistance while closing or opening. Any garage door opener sold in the United States after 1992 requires safety eyes—sensors that prevent the door from closing if obstructed. Force settings should cause a door to stop or reverse on encountering more than approximately 20 lbs (9.07 kg) of resistance. Safety eyes should be installed a maximum of six inches above the ground. Many garage door injuries, and nearly all garage door related property damage, can be avoided by following these precautions.
