Parts We Carry
Serenada's housing stock centers on 1981, which puts most garage doors here on hardware that's forty-plus years old if it's never been swapped. That means standard torsion springs sized for the lighter steel doors common in that build era, and in a fair number of single-car garages, extension springs run along the horizontal tracks instead of torsion springs over the header.
Wire sizes and diameters
We carry both. For torsion setups we stock the common wire sizes and inside diameters that fit doors from that period, plus the drums and shaft collars that wear alongside them. For extension setups we carry replacement springs along with safety containment cables - a lot of 1981 installs never had them, since that wasn't standard practice yet, and we won't put a bare extension spring back up without one.
Odd-width spring orders
One limit worth saying plainly: if your door is an odd width or a custom panel someone added later, we may need to order a spring rather than pull one off the truck, and that can push a job out a day or two.
Coverage of common doors
We don't stock every spring made. What we carry covers the vast majority of doors from Serenada's era and the decades around it, which is most of what we see out this way.

How We Fix It
A broken torsion spring on a door this age usually means the whole thing has simply reached the end of its cycle life - these doors have been opening and closing for over forty years, and unlike a newer spring sized for 10,000-plus cycles, older torsion springs were often undersized by today's standards.
Shaft and drum measurement
We unwind what's left of the old spring, measure the shaft and drum for wear, and replace the spring to match the door's actual weight rather than just matching the broken part - a mismatched spring on an older door is one of the more common comebacks we see.
Pulley and track checks
On extension spring doors we check the pulleys and the track alignment while we're in there, since 1981-era extension setups weren't always leveled the way code expects now, and an unlevel door puts uneven load on both springs at once.
Adding safety cables
If there's no safety cable, we add one. We don't just drop a new spring on and leave - mismatched or uncontained springs are how people get hurt, and it's not worth the shortcut for either of us.
How Long It Takes
We work out of Georgetown, about 3 miles from Serenada, so the drive itself isn't the bottleneck - a standard torsion spring swap on a door from this era typically runs under two hours once we're on-site with the right parts, which we usually have on the truck given how common this hardware is in a neighborhood built mostly in the 1980s. Extension spring jobs with cable upgrades run a little longer since we're adding a part that wasn't there before, not just replacing one.
Where it stretches out is custom widths or doors that have been modified over the years - Serenada is a small area, about 573 households, and we haven't run into many of those, but they do turn up. If we have to order a spring, that's the delay, not the trip out.
The Symptom
The door that won't budge, or lurches up a few inches and stops, is almost always a broken torsion spring - you'll often hear it go before you notice it, a loud bang from the garage that people sometimes mistake for something else entirely.
Crooked closing diagnosis
A door that opens fine but closes crooked, or one side visibly sags lower than the other, points to one spring on a double-spring torsion setup having given out while the other is still holding.
Loose pulley spring hazard
If your door is on the older extension-spring style - tracks instead of a shaft over the header - and the spring itself looks stretched out or has come loose from its pulley, don't try to force the door by hand.
Planned spring visits
Given the age of most doors in Serenada, we'd rather replace a tired spring on a planned visit than get the call after it fails while someone's standing underneath it.
