Springs for insulated doors
We carry standard cable drums, center brackets, and the heavier-wind springs that go on insulated double doors, since colder-climate construction here tends toward insulated doors with more weight to counterbalance.

Torsion and extension spring repair for Novi-area homes built 1938-1991. Same stock, same cold-climate fatigue pattern, parts on the truck.
The repair
A broken torsion spring on a double door is a one-visit job once we've got the right size and wind on the truck. We pull the old spring, measure the shaft and cable drum, set a new spring (or pair, on heavier doors) to the correct wind direction, and balance the door so it holds at waist height without the opener fighting it.
Extension spring setups along the horizontal track are a faster swap but need the same balance check or the door slams on its rollers. Most jobs run one visit, one spring size matched to the door weight and track type.
Where a job runs long is when the torsion shaft itself is bent or the cable drums are cracked from the broken spring whipping the shaft - that's not a spring repair anymore, that's a shaft-and-drum job, and we'll tell you straight when we see it rather than quote spring pricing for a bigger fix.
We don't carry every obscure wind pattern on the truck for every visit - some jobs built on odd-size doors from the 1960s-70s stock across this area need a day to source the exact spring, and we'll say so on the phone instead of guessing on-site.
Warning signs
The door won't budge, or it moves a few inches and stops. The opener strains and clicks but the door barely lifts - that's the opener trying to do a spring's job and it will burn out the gear doing it. You might hear a bang from the garage, usually mid-morning or overnight when the temperature swing stresses a spring that was already near its fatigue limit.
A cable that's gone slack on one side while the door sits crooked in the track is a spring failure, not a cable failure - the cable didn't break, it just lost the tension that was holding the door square. If you see a gap where the spring should be coiled tight over the shaft, or the two halves of a broken torsion spring sitting apart on the shaft, that's your answer. Don't pull the emergency release and try to lift it by hand with a broken spring; the door has no counterbalance and it's heavier than it looks.
On the truck
We stock torsion springs sized for the one-piece and sectional doors common in the 1960s-70s housing stock that makes up most of this area - Northville, Wixom, Walled Lake, Wolverine Lake, and the rest of the towns within about a dozen miles carry the same era of construction, so the same spring sizes cover most calls.

What we don't stock on the truck: springs for commercial-grade doors or oddball imported hardware from a door that's been swapped out of spec with the original opening. Those get special-ordered, and we'll tell you that up front instead of holding you up on-site guessing at a fit.
Local causes
Houses in this service area were mostly built between 1938 and 1991, with the bulk of the stock dating to the 1960s and 70s - that puts a lot of original garage door hardware at 50-plus years old, well past any spring's rated cycle count even with no abuse at all. A torsion spring is rated for a number of open-close cycles, not years, but age plus the cold-climate severity here compounds it: steel contracts in deep cold, and a spring already fatigued from decades of cycles is far more likely to let go on a frigid morning than a mild one.
Across the roughly 101,657 owner-occupied houses in this service area, most garages see daily use, twice a day for opener-based households - that's tens of thousands of cycles racked up since the Johnson administration on hardware nobody's touched since it was installed. We see the pattern most on original springs that were never replaced even once, on doors in unheated garages where the swing from a 70-degree house to single digits outside happens right at the spring.
Questions
We don't quote a number without seeing the door, the spring size, and whether it's a single or double - those change the parts cost. Call and we'll give you a real number over the phone once we know the door.
No. Without the spring's counterbalance, the opener is lifting the full weight of the door alone, which burns out the motor and gearing fast and can also pull the door off its track. Leave it shut and call.
Steel contracts when it's cold, which adds stress to a spring that's already near the end of its rated cycle life. A spring that would have lasted another season in mild weather can let go on the first hard cold snap, especially in an unheated garage.
Single doors typically run one torsion spring; double doors usually run two, sized to the door's weight and width. We confirm the exact setup when we're on-site rather than guess from a photo.
