How much does it cost to install a standby generator at home?

Costs vary by home and load needs. We give free estimates and upfront pricing after an on-site assessment. Generator size (kW), required gas line work, transfer switch or panel upgrades, whole-house surge protection, and site conditions drive the final price. We are a Generac certified dealer, recommend the right model, and handle the gas line so you work with one contractor. Financing is available. A $250 off new generator installation promotion is available in Warrenton, VA.
