How It Works

Operators generate leads before storm season, quote shelter type and size, coordinate permits and engineered specs, excavate or prep slabs, deliver shelters, anchor or install units, restore the site, and help customers navigate rebates where available. Revenue comes from residential installs, school and workplace shelters, inspections, repairs, and accessories.
