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

A home standby generator installation is priced after an in‑home assessment; Streamline offers free install estimates and financing options with payments as low as $39/month through GreenSky (on approved credit). Most price differences come from the generator’s capacity needs and the scope of electrical integration required to power your selected circuits or whole home.

We install and maintain generators for homeowners across the Wake Forest area with code-compliant design, professional setup, and complete testing and verification.

• Key cost drivers include generator size (kW) and whether you choose essential circuits or whole‑home coverage.
• Fuel configuration and gas work (natural gas or propane) can add material and labor needs.
• Electrical upgrades like transfer switches, service upgrades, or panel space affect install time.
• Site factors such as pad location and distance to utilities influence trenching and wiring.

A quick field note: a properly matched transfer switch is often the make‑or‑break component for seamless, safe operation.
