Garage Door Spring Repair
A broken spring is the most common reason a garage door stops lifting, and it is not a safe DIY job. G Brothers replaces torsion and extension springs, same day, at a flat rate you approve first. We size the spring to your door so the balance is right and the new spring lasts its full cycle life.

What this service covers
Real work by background-checked local technicians, quoted at a flat rate you approve before anything begins.
Torsion and extension springs
We replace the spring type your door uses, sized to the door weight and drum for correct balance.
Springs replaced in pairs
On two-spring doors we replace both, because the second spring is near the end of its life when the first breaks.
High-cycle upgrades
We can step you up to high-cycle springs for a longer service life on doors that run often.
Signs of a broken or worn spring
A loud bang from the garage, then a door that will not open
The door lifts a few inches and stops or feels very heavy
A visible gap in the torsion spring above the door
The opener strains or the door slams down
