A spring job is priced by what's actually broken, not by a flat number over the phone. Torsion springs come in different wire gauges and wind counts depending on door weight and age, and the houses in this service area span four decades of construction, from 1971 up through 2011. A single steel door on an older torsion setup is a different job than a heavier insulated door on a newer bracket. We don't quote a number until we've looked at the door, because a spring sized wrong will fail again inside a year and that costs the homeowner twice.
What we can tell you without seeing the door: extension springs and torsion springs aren't interchangeable repairs, and a double-door setup with two springs usually means replacing both even if only one snapped, since the other is on the same clock. We also won't sell a spring-only fix on a door where the drums, cable, or track are also worn past spec - that's not a repair, that's a callback waiting to happen. If a tech tells you the door needs more than a spring, ask what and why.
Most homes across this service area - 57,010 owner-occupied houses among 125,897 households - were built between 1971 and 2011, with the bulk of that stock going up in the 1980s and 90s across the 26 named communities we work in. That era of construction favored steel torsion springs mounted on a center shaft above the door, a design that's reliable for years but has a fixed fatigue life measured in door cycles, not calendar time.
The mild temperate climate here doesn't add the rust and ice-load stress that springs see in harsher regions, but it doesn't slow the fatigue clock either. A spring wound to a set tension eventually work-hardens and snaps regardless of weather, and a 1989-built door getting opened twice a day has been cycling for over three decades. Humidity does play a role at the margins - moisture sitting on an unlubricated coil accelerates the surface corrosion that starts a crack. That's a maintenance issue more than a climate one, and it's the most common thing we find when a spring lets go early on a door that otherwise looks fine.
A door that won't budge, or one that slams down instead of lowering - that's a broken spring, not a dead opener. If you pull the release cord and the door feels like dead weight instead of lifting on its own, the spring that was supposed to carry that weight is gone. A visible gap in the coil above the door, or a loud bang from the garage right before the door quit working, both point the same direction.
On older torsion setups common in this area's 1980s and 90s housing, you'll sometimes see one side of the shaft sitting lower than the other - that's a single spring failure on a two-spring system, and the door will look crooked when it's partway up. On a door with extension springs along the horizontal tracks instead, a snap usually leaves one spring stretched loose and dangling. Either way, don't try to force the door up by hand or with the opener - that transfers all the load to the cables and drums, and that's how a spring repair turns into a track and cable repair.
A straightforward torsion spring replacement, once we're on site and have the right spring on the truck, usually runs under two hours. Where the time goes is diagnosis and matching: an older door from the 1980s or 90s housing wave may need a spring size that isn't a common stock item, and pulling the wrong wind or wire gauge onto a shaft is worse than leaving the door broken. We carry a working range on the truck and can special-order the rest, but that's a limitation worth saying plainly - an unusual spring on an older door can mean a short wait rather than a same-visit fix.
Double-door jobs with two torsion springs take longer than single-spring jobs on a single door, mostly because we're balancing both sides to the same tension before we call it done. We test the door through a full cycle, check the cables and drums for wear from the failure, and won't leave a job half-finished just to hit a time target.
It depends on spring type, door weight, and whether one or both springs need replacing. We don't quote a firm number until we've seen the door, since guessing on spring size leads to a repair that fails again within months.
Springs fail by fatigue, not sudden damage. A spring wound for a set number of cycles eventually work-hardens and snaps, and homes built in the 1980s and 90s wave common across this area have had decades of daily use on the original hardware.
You can, but we generally don't recommend it. Both springs went in at the same time and carry the same cycle count, so if one snapped, the other is close behind. Replacing both now is usually cheaper than a second callback later.
Not for long. Without the spring carrying the weight, the door's full load shifts onto the cables and drums. Forcing it open by hand or with the opener risks turning a spring repair into a bigger cable or track job.
