The Symptom
The door won't lift, or it lifts a few inches and stops. Sometimes you hear a bang from the garage overnight and the next morning the door is dead weight - that's a torsion spring letting go. You might see a gap in the coil sitting above the door, or one side of the door hanging crooked while the other side looks fine. On double doors with two springs, one spring can snap while the other holds, which lets the opener keep trying and burn out the motor if nobody catches it. If the door feels unusually heavy when you lift it by hand with the opener disconnected, the spring is on its way out even if it hasn't broken yet. This is a mechanical failure, not an opener problem, and no amount of adjusting the remote or the sensors fixes it.

What Causes It Around Here
Most of the housing across Bettendorf and the surrounding service area went up between 1948 and 2001, with the heaviest concentration from the 1960s and 70s across the ten communities we cover. Springs installed on doors from that era are decades past any reasonable service life, and a lot of them were never upgraded when the door itself got replaced - a new door bolted onto old torsion hardware is one of the most common setups we find. Add in a cold-moderate climate where temperatures swing hard between summer and winter, and steel coil springs lose tension faster than they would somewhere milder. Cold makes the steel more brittle right when the door gets used the most, pulling cars in and out during storms. A spring rated for a certain number of cycles doesn't care how old the house is, but older homes in this area are more likely to be running the original spring, or close to it, which is why this job shows up so often on pre-1980 construction.
Where This Job Goes Sideways
Torsion springs are under enough tension to break bones if you wind or unwind them wrong, and that's the main reason this isn't a weekend fix with tools from the garage.
Mismatched spring pairs
The job also goes sideways when a homeowner replaces just the broken spring and leaves its matching pair in place - the second spring is usually close behind and now it's a mismatched set carrying the door unevenly.
Worn bearing plates
On older torsion setups with worn bearing plates or a bent shaft, swapping the spring doesn't solve the real problem, and the new spring wears out fast under the extra strain.
Spring-only repair limits
We'll be straight about one limitation: if the drum, shaft, or center bearing is already damaged, a spring-only repair is a short-term patch, and we'll tell you that instead of selling you a spring and letting you find out in six months.
The Cost of This Job
We don't publish a flat number here because spring size, door weight, and whether one or both springs need replacing all change the math, and we'd rather quote it after looking at the door than print a figure that doesn't match your setup. What we can tell you is the factors that move the price: single versus double spring, standard torsion versus extension spring systems common on older garages, and whether the drums or cables need attention at the same time. Given that median household income across the service area runs around $84,380, most jobs land in a range homeowners here plan for rather than one that requires financing. Call and we'll walk the door with you before anything gets charged.
