Is it worth fixing a garage door spring?

Yes, it is almost always worth fixing a garage door spring because the alternative is replacing the entire door system or being unable to use your garage, and spring replacement is a relatively low cost repair compared to full door or opener replacement. A broken spring makes the door extremely heavy, 150 to 300 pounds, and impossible to lift safely by opener, so without fixing it your garage is essentially non-functional and your car is trapped or your home security is compromised. Professional spring replacement costs 200 to 400 dollars for a single torsion spring and 300 to 600 dollars for a pair, including parts and labor, which is far less than replacing a garage door costing 800 to 3000 dollars or an opener costing 300 to 600 dollars that can be damaged if you keep trying to operate it with a broken spring. Fixing the spring also restores safety, as operating with a broken spring can cause the door to fall, go off track, or damage cables. Since springs are wear items rated for about 10,000 cycles or 7 to 10 years, breaking is normal and expected, not a sign the door is bad. Investing in high-cycle springs rated for 20,000 cycles costs slightly more but doubles lifespan. If your door is very old, rusted, or you have had multiple other repairs, you might consider full replacement, but for most doors under 20 years old, spring repair is definitely worth it and extends life many years.
