Garage door installer insurance — cost, coverage, and the spring liability issue

Garage door installation has one of the highest worker injury rates of any residential trade — torsion springs store mechanical energy comparable to a loaded firearm, and a single mishandled spring release can cause serious injury or property damage. The premium reflects this risk profile, but the insurance protection it buys is essential for both the installer and the business.

What garage door installer insurance covers

• General liability ($1M): third-party injury (customer family members, neighbors), property damage to vehicles and garage contents.
• Completed-operations coverage: claims arising after the install is done — door malfunctions, opener failures, spring breaks. Critical for this trade.
• Tools & equipment: spring winding bars, torque wrenches, lift equipment, specialized installation tools.
• Workers comp: essential. Garage door work has high injury severity for workers.
• Commercial auto: service trucks and trailers.

What it costs

• Solo garage door installer: $700–$1,300/year for $1M GL
• 2-3 person crew: $1,200–$2,500/year + workers comp
• Commercial garage door company: $2,500–$6,000/year
• Workers comp: high relative to other trades — budget $3,000–$8,000/year for a 2-person crew

The spring-injury issue

Torsion springs are the highest single risk factor in garage door work. The legal and insurance landscape:

• Workers comp claims from spring incidents regularly hit $30K-$100K. Broken bones, severe lacerations, eye injuries are common.
• GL claims when customers or family members are injured by spring releases — particularly common when customers attempt to "help."
• Completed-operations claims when an installed spring fails weeks or months later — door drops, vehicle damaged, family member injured.
• Mitigation: proper training, spring winding bars used correctly every time, customer/family kept clear of work area. Document safety protocols.

Common garage door installer claims

• Worker injury from spring tension release. Highest-severity claim type.
• Property damage to vehicles in garage during installation.
• Damaged garage contents — stored items, refrigerators, shelving.
• Completed-operations failures — door drops after install, opener fails causing damage.
• Electrical issues from opener installation — fires, electrical damage.
• Tool/equipment theft from service trucks.

Why completed-operations coverage matters most here

Garage door failures often happen weeks or months after installation — a spring breaks, a cable snaps, an opener motor fails. The customer is hurt, a vehicle is damaged, and the claim comes back to you. Completed-operations coverage (usually included in GL but verify) covers these post-installation claims. Without it, your GL won't respond.
