The biggest mistakes homeowners make with garage door spring repair

Published August 29, 2026

What really happens when a garage door spring breaks in Las Vegas

When a garage door torsion spring lets go, it usually happens fast: one moment the door is working, the next you hear a loud snap and the door will not lift. In the Las Vegas valley this often shows up first thing in the morning when someone hits the remote to leave for work and the door barely moves. The opener may hum or strain, but with a broken spring the heavy lifting that the spring normally provides is gone. That is why the door suddenly feels impossible to lift by hand.

The Door & Access Systems Manufacturers Association (DASMA) explains that springs are designed to counterbalance the weight of the door so that it can move smoothly and stay in place at different heights. When a spring breaks, that balance is lost, and the full weight of the door is now bearing on the opener, tracks and remaining hardware. In our climate, heat, dust and normal metal fatigue all work together on those coils over time. Knowing what is actually happening inside the system helps you see why some common homeowner reactions are not just small mistakes but can lead to extra damage.

A quick visual check from the ground can confirm the problem. With the door fully closed and the opener off, look at the torsion spring above the door. If you see a visible gap in the coil, the spring is broken. You do not need to touch it or get on a ladder to know. At that point, the safe move is to stop using the opener and plan for a professional garage door spring repair, not to keep cycling the door or trying to force it.

• Listen for a loud bang followed by a heavy, nonmoving door.
• Look for a visible gap in the torsion spring coil from the ground.
• Do not keep pressing the opener if the door barely moves.
• Keep the door closed until a professional inspects it.

Mistake 1: Treating broken torsion springs as a DIY project

One of the biggest mistakes we see around garage door spring repair is assuming it is just another home project if you are handy with tools. Torsion and extension springs hold the door's weight under high tension. According to DASMA's residential safety tips, adjustments to springs and bottom brackets should only be performed by trained door systems technicians because releasing that stored energy the wrong way can cause serious injury or damage.

DASMA's technical data sheet on spring cycle life also makes it clear that details like how many turns a spring is wound, the direction it is wound, and whether the spring matches the door's weight all affect both performance and safety. Winding a torsion spring backwards or setting the wrong torque are listed as major errors. That is why any step-by-step winding or unwinding guide you find online is still not a substitute for training, the right bars, and knowledge of current standards. In the same way that UL 325 and 16 CFR Part 1211 expect openers to be installed on properly balanced doors by qualified people, spring work is not a place to experiment.

If you are in a Summerlin, Henderson or North Las Vegas garage, the safest division of work is simple. Homeowners can safely test the opener's reversal using a scrap piece of wood on the floor, keep photo eyes clean, and look for obvious signs like a broken coil or a frayed cable. Anything that involves loosening set screws, touching the spring, removing a bottom bracket, or unhooking a cable belongs to a professional. Treating springs, cables and drums as professional-only work is not about selling service. It is about respecting the stored energy that keeps a two-hundred pound door moving.

• Do not loosen set screws on torsion springs yourself.
• Do not remove or detach lift cables or bottom brackets.
• Do not follow online winding tutorials as a substitute for training.
• Do schedule a professional if you spot a broken spring or frayed cable.

Mistake 2: Running the opener on a door with a broken or weak spring

Another costly mistake is to keep using the garage door opener after a spring has broken or when the door feels unusually heavy. Many Las Vegas homeowners try this once or twice just to "get the car out" and hope the opener can muscle the door up. The problem is that the opener is designed to move a balanced door, not to act as a winch that lifts the full weight of the door on its own.

UL 325 and the federal rule at 16 CFR Part 1211 require that opener instructions warn users to install and use the operator only on a properly balanced door. When a torsion spring has failed, the door is no longer in that condition. Continuing to run the opener can strip gears, bend the rail, and stress the door sections. In some cases the opener may stall partway up, leaving the door hanging unevenly which is an unsafe position around vehicles and people.

In our desert climate, this is sometimes made worse by heat-thinned lubricants and dust in the tracks, which add friction on top of the missing spring assist. The smart move is to disconnect the opener only if the door is fully closed, leave the door down, and arrange for a professional garage door spring repair. If your car is trapped inside and you are tempted to force the door up, that is the moment to call for same-day emergency help rather than risk a strained back or a dropped door.

• Stop using the opener as soon as a spring breaks.
• Do not force the door up by hand if it feels extremely heavy.
• Keep the door closed until a technician inspects the springs.
• Use emergency service if a vehicle is trapped and the door will not lift.

Mistake 3: Replacing only one spring or using the wrong size

Many two-car garages in the Las Vegas area use a pair of torsion springs. When one breaks, it is tempting to ask for the cheapest possible repair and replace only the broken coil. DASMA's safety tips recommend replacing both springs when there are two, even if only one has failed, because they are engineered to work as a set and are usually the same age. If you only swap one, you end up with one new spring and one tired spring, which can leave the door out of balance and cause the older spring to fail sooner.

DASMA's technical data on spring cycle life also explains that springs must match the door's counterbalance requirements. That includes the correct wire size, coil diameter, length and number of turns. Installing a spring that is too strong or too weak for the actual door weight changes how much force the system applies. Too much torque can cause the door to shoot up or slam at the top, while too little torque means the door will not stay open or may drift down. Both are safety issues, especially around children and vehicles.

In planned communities around Henderson and the northwest valley, different build eras used different door sizes and construction, from lighter single-layer doors to insulated steel models. A professional who services all makes and models will weigh the door when needed and select springs that match, rather than guessing by sight. The right approach is to ask your technician how they are sizing the springs, whether both will be replaced if your setup uses a pair, and how they will confirm that the door is balanced after the work.

• Ask whether your door uses one or two torsion springs.
• Replace both springs on a two-spring system whenever one breaks.
• Confirm that the technician is sizing springs to the actual door weight.
• Have the balance of the door tested after new springs are installed.

Mistake 4: Ignoring cables, hardware and safety systems during spring repair

Focusing only on the broken spring and skipping the rest of the system is another common mistake. DASMA's safety guidance points out that when springs wear, other parts like lift cables and bottom brackets also see years of stress. Cables can fray, drums can wear unevenly, and fasteners can loosen. If those issues are not caught during spring replacement, you may have a door that works for a short time, then jumps a cable or goes out of level.

Industry standards such as ANSI/DASMA 103 for counterbalance systems also describe how torsion springs, anchors and related hardware must be matched to the forces involved. That is the engineering side. On the homeowner side, what matters is that your technician takes time to inspect the anchor plate, center bearing, end bearings and fasteners, not just slide on a new spring and leave. A quick visual cable check from the ground is something you can do yourself between visits, but adjusting hardware that carries spring tension belongs to a trained person.

Your opener's safety systems tie into this as well. Federal rules that incorporate UL 325 have required residential garage door openers manufactured on or after January 1, 1991 to meet entrapment protection requirements, and a secondary protection device such as photo eyes has been required on openers manufactured on or after January 1, 1993. After any spring repair, it is wise to run a full safety test: check that the photo eyes stop and reverse the door when the beam is blocked, and use a piece of wood on the floor to confirm the door reverses when it makes contact. A properly balanced door makes those protections work the way they were designed.

• Ask for a full hardware and cable inspection with any spring repair.
• Have the technician check spring anchors and bearing plates for wear.
• Test photo eye reversal and contact reversal after the work.
• Watch and listen to the first few full open-close cycles post repair.

Mistake 5: Choosing a spring repair provider on convenience alone

The last big mistake is treating garage door spring repair like any quick household errand, where the first number you find is good enough. A spring carries the weight of the heaviest moving object in most Las Vegas homes, and it sits over a space that people, vehicles and storage use every day. Who you trust with that work matters. You want someone who understands both the local climate factors and the national safety standards that apply to doors and operators.

For homeowners across the valley, a good starting point is to confirm that the contractor is licensed, bonded and insured, and that garage doors are their specific trade. Prestige Garage Door Services, for example, holds Nevada contractor license 0091256, classification C-3D Overhead Doors and brings 35+ years of experience in the trade. That kind of focus means the technician is used to dealing with older extension spring setups in areas built in the 1980s, one-piece doors in parts of East Las Vegas, and newer torsion systems in communities built in the 2000s.

You can also ask how they handle inspections and pricing. A company that offers a free inspection, gives the price before work starts, and is clear about what is and is not included is usually more focused on long-term safety than on a quick visit. If you need 24/7 emergency service, verify that it is truly available, not just promised. Finally, ask what kind of workmanship warranty they offer on spring repairs, and how they handle follow-up if you notice anything unusual in the first few weeks. A calm, straightforward answer to those questions is a good sign that your door is in experienced hands.
