Extension or torsion, left-wound or right-wound, spring replacement is precision work. We calculate the exact spring specification before winding anything into place.
A mismatched spring either fails early or overloads the opener. We size it correctly every time.
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.
Higher cycle-rated springs cost a bit more upfront and last considerably longer under daily use.
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.
Worn extension springs stretch unevenly over time. We replace both sides together with new safety containment cables.
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.
Technicians arrive with multiple spring sizes and wire gauges already stocked, ready for common configurations.
We measure the door weight, wire gauge, and coil diameter, then quote the exact spring spec before work begins.
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.
We'll tell you the second spring's estimated remaining life so you can decide with real information.
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.
Most spring replacements are completed same-day, often within one to two hours once the technician arrives.
Same-day dispatch, upfront pricing, and a written warranty on every visit.
