Generators Contractors in West Allis, Wisconsin

Standby and portable generator installation and service..

West Allis is a major Milwaukee suburb with older homes and active roofing contractor markets.

Whole-home standby generators automatically provide backup power during outages, protecting against food spoilage, frozen pipes, sump pump failure, and loss of medical equipment. Natural gas or propane-fueled standby generators (typically 12–24 kW for residential use) start within seconds of a power outage via an automatic transfer switch. Installation involves an electrical subpanel or whole-house transfer switch, a concrete pad, gas line connection, and compliance with setback and noise ordinances. Portable generators serve as a lower-cost option for partial backup but require manual setup and fuel management.

What to look for when hiring a generators contractor

  • Ask the installer to perform a load calculation to properly size the generator for your home.
  • Confirm the estimate includes the transfer switch, concrete pad, gas line, and all permits.
  • Ask about warranty terms — most major brands offer 5-year limited warranties.
  • Verify the installer is authorized by the generator manufacturer (Generac, Kohler, Briggs & Stratton).
