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

Home standby generator installation cost is custom to each home and finalized after an on-site assessment. The largest cost driver is the generator size required to support your essential circuits during an outage. We install and service generators throughout the Roanoke region with licensed, background-checked technicians. $500 off complete generator installation is currently offered; call to confirm eligibility and any restrictions.

Key factors that set the final price:

• Power capacity (kW) and whole-home vs. essential-circuit coverage
• Fuel source (natural gas or propane) and meter/tank readiness
• Transfer switch type and any electrical panel upgrades
• Site work, pad placement, trenching, and distance to utilities
