Most repairs same day
Torsion springs above a garage door: snapped, and a new pair
Six jobs
Springs, openers, cables and new doors for Littleton and the south Denver suburbs. Every job has its own page, and five of them carry their price right here.
We replace broken torsion and extension springs on residential garage doors, usually the same day you call, and rebalance the door before we leave.
We repair and replace garage door openers, including the gear kits, sensors and remotes, and we can swap a worn opener for a quiet belt drive in one visit.
We put doors back on their tracks and replace snapped or frayed lift cables, then check the rollers, hinges and balance before the door goes back into service.
We measure, order and install new steel or insulated garage doors, take the old door away, and set up the opener to run on it.
A yearly service visit: we balance the door, tighten the hardware, lubricate the moving parts and test the safety reverse, so small problems are caught before they strand a car.
For the door that gives out after hours. Call (720) 555-0142 and say what happened.

Broken spring replacement

A broken spring is the one that sounds like a gunshot in the garage, and the door will not lift after it.
The common sizes ride on the van, so most calls are done in one visit. On a two-spring door both get replaced, because the second one is the same age and will go soon after.
Spring replacement, $385
Emergency after-hours service
When the door gives out after hours and the car is on the wrong side of it, call and say what happened.
