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.
We won't hide the recommendation to replace both, but the final call on timing is always yours.
This is the one repair where licensing and training genuinely protect you, not just the door.
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.
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.
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.
We estimate remaining cycle life based on door usage and spring age, so you can replace before a sudden failure strands you.
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.
Precise measurement comes first, then a confirmed flat price for the correct spring.
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.”
“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.”
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.
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.
Licensed technicians, flat-rate pricing, and a truck stocked for this exact job.
