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

A home standby generator installation typically costs $5,000 to $15,000 including the generator and professional installation. Your price mainly hinges on the power capacity you choose for whole‑home coverage versus just essentials. Final pricing is confirmed after an on‑site assessment, and we provide a free, detailed quote before work begins. Our electricians handle permitting and inspections, and we routinely coordinate with the City of Redmond for code‑compliant installs. A practical rule our techs use: size the generator to the largest likely simultaneous loads, not just nameplate totals. Financing options are available if you prefer predictable monthly payments.

Key factors that move price up or down:

• kW size selected for your must‑run circuits
• Gas line or propane tank work and distance to the unit
• Transfer switch location, panel upgrades, and trenching needs
• Site prep like concrete pad and clearance requirements
