In our years serving Milliken, we've seen this problem again and again: homeowners hear a loud crack, their garage door hangs crooked, and they realize their springs have failed. A snapped spring is one of the most common garage door emergencies, and it's one you cannot ignore. The answer is straightforward: you need professional replacement, not a DIY patch, and the sooner the better.
Garage door springs work under tremendous tension. Every time your door opens or closes, these metal coils support roughly half the door's weight, cycling thousands of times per year. Most residential springs last between 7 and 9 years before metal fatigue causes them to snap. That's simply physics, not poor maintenance.
Two main types handle this load in Milliken homes. Torsion springs sit above the door, running horizontally, and are the most common in modern installations. Extension springs hang on either side of the door track and work by stretching. Both wear out predictably, but when they fail, they fail completely and suddenly. There's no gradual decline to warn you.
Cold Colorado winters accelerate this wear. Metal becomes more brittle in freezing temperatures, and our seasonal swings from below zero to mild afternoons stress the springs faster than in stable climates. If you live near Broomfield or Boulder, you're dealing with identical conditions.
A snapped spring produces an unmistakable sound: a loud crack or bang inside the garage. After that, your door becomes heavy to open by hand. The automatic opener may struggle or fail entirely. Some homeowners notice the door opening unevenly, hanging lower on one side. This imbalance is dangerous and signals immediate replacement needed.
Never attempt to lift or operate a door with a broken spring. The door can drop suddenly, causing serious injury. This is not a situation for improvisation. If you spot these warning signs, call for a professional estimate and same-day service if available. For a detailed breakdown of early indicators, our guide on 5 signs you need a garage door spring replacement covers what to watch for before failure happens.
Spring replacement costs vary based on spring type and door size. A single torsion spring typically runs between $150 and $300 for the part alone. Extension springs cost slightly less per unit, usually $75 to $150 each. Labor adds another $150 to $300 depending on complexity and whether both springs need replacement.
Most professionals recommend replacing both springs at once, even if only one has failed. The second spring is near the end of its life anyway, and replacing both prevents a second emergency call within months. Total cost for a complete spring replacement usually falls between $300 and $600.
This is one area where cheap matters less than quality. Bargain springs fail faster. We source heavy-duty springs rated for Colorado's temperature extremes, and that choice adds modest cost upfront but saves you money over years.

We've invested in the right equipment because doing the job right means nobody gets hurt.

Spring failure is urgent, but it's also fixable. The key is getting a qualified technician to handle it safely and right the first time.
How long do garage door springs last? Most residential springs last 7 to 9 years under normal use. Colorado's temperature swings can shorten lifespan to 5 to 7 years. Cycles, not time, drive wear, so heavy-use doors fail sooner than lightly-used ones.
Can I replace just one broken spring? You technically can, but we recommend replacing both. If one is snapped, the other is near failure. Replacing both eliminates a second emergency within months and costs only slightly more upfront.
What's the difference between torsion and extension springs? Torsion springs run horizontally above the door and handle tension more efficiently. Extension springs run vertically along the tracks. Torsion springs are standard in modern doors and typically last longer. Your door type determines which you have.
How much does spring replacement cost near Milliken? Total cost ranges from $300 to $600 for both springs plus labor. Heavy-duty springs and same-day service may run higher. Call (720) 408-6434 for a free estimate tailored to your door and situation.
Is a broken spring a safety issue? Yes. A door with broken springs can drop suddenly and cause injury. Never operate a door with a snapped spring. Contact a professional immediately for safe replacement.
