Extension or torsion, left-wound or right-wound, spring replacement is precision work. We calculate the exact spring specification before winding anything into place.
We calculate wire gauge, coil diameter, and wind direction against your door's actual weight before installing anything.
A single-spring swap on a pair often means a second failure within months. We'll lay out the tradeoff honestly.
Winding bars, proper sequence, and hands-on training are non-negotiable when a spring is under load.
The spring installed is chosen for durability, not just for passing the next inspection.
Whatever brought you here, one of these service lines is the fix, and one call gets a technician moving.
We calculate the correct torsion spring specification, then use proper winding bars and sequence to install it safely.
Extension springs are replaced in matched pairs with new safety cables, since a mismatched pair throws the door off balance.
A snapped spring means the door won't move safely. We carry multiple spring sizes on every truck for a same-visit fix.
A torsion conversion adds an overhead shaft and drums, trading exposed extension springs for a safer, more durable setup.
We estimate remaining cycle life based on door usage and spring age, so you can replace before a sudden failure strands you.
A quick description of the spring symptom gets the right parts loaded on the truck before arrival.
Our vans carry the spring inventory needed for most jobs without a parts run.
Precise measurement comes first, then a confirmed flat price for the correct spring.
Spring installed, tension set, balance tested, and backed by written warranty before we leave.
“Diagnosed the exact wire gauge needed and had it on the truck already. No parts run, no delay.”
“Converted our old extension springs to a torsion system. Door is noticeably quieter and smoother now.”
“Preemptive spring check caught one close to failure before it snapped. Glad I called before it stranded us.”
Pricing varies by spring size and door weight, quoted upfront on-site with no hidden add-ons.
On a torsion pair, we recommend both since the second spring is on the same wear cycle, but we'll explain the reasoning and let you choose.
This is one of the more dangerous DIY repairs in a home due to the stored energy involved.
Higher cycle-rated springs can last well beyond a decade under normal household use.
Correct spring sizing protects both the door balance and the opener motor long-term.
A standard spring swap typically takes under two hours on-site with the correct part in stock.
