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.
A loaded torsion spring can cause serious injury if mishandled. Our technicians are trained specifically on safe unwinding and winding procedure.
We install springs rated for the cycle life your usage actually demands, not the cheapest option on the shelf.
Each service below is handled by a technician trained specifically for this kind of repair, not a generalist guessing at it.
Precise torsion spring replacement matched by wire gauge, coil diameter, and wind direction to your specific door weight and track configuration.
Extension springs are replaced in matched pairs with new safety cables, since a mismatched pair throws the door off balance.
Sudden spring failure gets same-day priority since a broken spring makes manual operation dangerous.
A torsion conversion adds an overhead shaft and drums, trading exposed extension springs for a safer, more durable setup.
Springs rated for 10,000 cycles wear predictably. We'll tell you honestly how much life is left before it becomes an emergency.
Describe the spring symptom, a loud bang, a sagging door, or a door that won't lift, and we'll schedule a technician.
Our vans carry the spring inventory needed for most jobs without a parts run.
We measure the door weight, wire gauge, and coil diameter, then quote the exact spring spec before work begins.
The door is verified balanced and safe to operate before the job is called complete.
“Diagnosed the exact wire gauge needed and had it on the truck already. No parts run, no delay.”
“They measured everything before quoting instead of eyeballing it like the last company did.”
“Balance test after the install showed the door lifts perfectly by hand now, opener disconnected.”
Cost depends on spring type, wire gauge, and whether one or both springs need replacing, confirmed as a flat price before work starts.
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.
Yes. A torsion spring under tension can cause serious injury if released without proper tools and technique.
Higher cycle-rated springs can last well beyond a decade under normal household use.
A spring that's too weak puts extra strain on the opener with every cycle, accelerating wear.
A standard spring swap typically takes under two hours on-site with the correct part in stock.
