How This Research Was Conducted
The report combines public demographic and injury data, manufacturer engineering specifications, compiled trade-source statistics, national household spending data, and national repair cost guides. It does not report proprietary Local Garage Door Specialist service-call totals.

Analytical Approach
The estimated garage-door-equipped home base applies a commonly cited 66% national garage or carport rate to 340,962 Gwinnett housing units. Annual replacement events are calculated by dividing approximately 225,000 equipped homes by the typical 7-to-10-year lifespan range. The 8.5-year midpoint produces approximately 26,500 events. Cycle-to-year examples use four and six daily open-and-close cycles.
Limitations
- The county figures are modeled estimates, not direct counts or actuarial forecasts.
- The 66% garage or carport prevalence rate is national and may differ in Gwinnett County.
- Spring life varies with product, installation, maintenance, climate, and usage.
- The 30% service-call share comes from compiled industry sources rather than a measured countywide dataset.
- Repair prices are national ranges and may vary locally.
- The CPSC injury range covers garage-door incidents broadly and is not specific to springs, DIY repair, or Gwinnett County.
