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

Installing a standby generator at home is a custom-priced project confirmed after an on-site assessment. The biggest cost driver is the generator’s size (whole-home vs essential circuits) and how it integrates through the transfer switch. For a typical mid-size single-family home, a professionally installed standby generator project commonly ranges from about $15,000 to $30,000, depending on site conditions and scope Labor can vary because the transfer switch and panel tie-in often determine as much work as the generator itself. After a visit, we provide up-front per‑job pricing and handle required permits and inspections. We install and service Briggs & Stratton systems throughout the Atlanta area, including Tucker.

Key factors that set the final price:

• Generator capacity and Briggs & Stratton model selection
• Fuel source and any gas-line work (natural gas or propane)
• Transfer switch type and whole-home vs partial-circuit integration
• Site placement, wiring distance, and any panel/service upgrades

Have a licensed electrician evaluate load, gas capacity, and placement before you purchase any unit.
