The most common garage door repair — and one you should never attempt yourself.
Garage door repair in San Diego starts with a $125 service call that's applied toward the work; spring replacement starts at $600. Castle has served San Diego to Riverside County since 1981 — family-owned, CSLB #1154002.
A broken garage door spring is the single most common reason homeowners call for garage door repair. You might hear a loud bang from the garage, or simply find that your door won’t open one morning. Springs bear the full weight of your garage door — typically 150 to 250 pounds — and when they fail, the door becomes inoperable.
Torsion springs are mounted on a metal shaft above the door opening. They use torque to lift the door and are the most common type in modern installations. Most residential doors use one or two torsion springs.
Extension springs run along the horizontal tracks on both sides of the door. They stretch and contract to provide lifting force. These are more common in older homes and lighter doors.
Garage door springs are under extreme tension. A torsion spring stores enough energy to cause serious injury or death if handled improperly. This is genuinely one of the most dangerous home repairs you can attempt. Our technicians are trained and equipped with the proper tools to handle spring replacement safely.
