Spring repair is one of the highest-risk garage door jobs. A broken torsion or extension spring can leave a door extremely heavy, trap a vehicle inside, and damage the opener if it keeps trying to lift. Mars techs replace springs as a balanced pair, check the cables and drum at the same time, and cycle-test the door before leaving.
A garage door is a system, not a single part: sections, track, rollers, hinges, cables, springs, opener, safety sensors, and weather seals all affect how it operates and whether it's safe to keep cycling. When a Mars tech writes up a repair, you should walk away knowing what failed, whether anything else was damaged in the process, and what prevents the same failure from happening again.

Garage door springs carry the door weight, and a failed spring changes the load on every connected part. A door that suddenly feels heavy may also have loose cables, damaged drums, bent hinges, or an opener that has been strained by repeated lift attempts. Mars checks the full lift system before replacing springs because putting new springs on damaged hardware can leave the door unsafe, noisy, or out of balance after the obvious broken part is gone.
Spring pricing changes with door height, door weight, spring cycle rating, torsion versus extension hardware, cable condition, access to the shaft, and whether both springs should be replaced as a balanced set. A single broken spring on a two-spring system often means the other spring has the same age and cycle wear. Replacing only one can save money today, but it may create a second service call soon after. Mars explains that trade-off before work starts.
Most repair calls are same-day or next-morning depending on parts and how booked the route is. Spring failures and stuck-open doors get triaged first because the door is unsafe to leave that way. Same-day means parts are in stock and a tech is available — Mars does not promise a guaranteed arrival window.
Typical range. Exact price quoted upfront before any work. $199 minimum visit. Covers the trip, diagnosis, and any adjustment that fixes your door. Door size, weight, parts on the truck, and anything else damaged in the same failure can move a job inside that range. 1-year labor warranty on every repair; parts carry the manufacturer's warranty.
