Backup Generator Installation

Standby and portable generators that keep your home powered.

Overview

Winter storms and grid outages don't have to mean spoiled food, frozen pipes or a cold house. We design and install natural-gas and propane standby generators from Generac, Kohler, Cummins and Briggs & Stratton, paired with automatic transfer switches that restore power within seconds. Whether you need to protect a few critical circuits or run your whole home, we'll size, install and commission a system that's ready every time the lights go out.

Benefits

  • Automatic transfer within seconds of an outage
  • Natural-gas or propane — no refuelling required
  • Whole-home or essential-circuits configurations
  • Annual maintenance plans available

Our Process

  1. Sizing consultation

    We measure your essential loads and recommend a generator and transfer switch sized to match.

  2. Site review & quote

    We confirm generator location, fuel routing, exhaust clearances and provide a fixed quote.

  3. Permits & gas coordination

    We handle the electrical permit and coordinate the gas fitter for the supply tie-in.

  4. Installation & commissioning

    Pad, generator, ATS and wiring are installed, then the unit is started, load-tested and programmed for weekly exercise.

  5. Owner orientation

    We walk you through controls, maintenance intervals and what to expect during the next outage.

Frequently Asked Questions

How big a generator do I need?

Essential-circuit setups typically start around 10–14kW; whole-home installations for medium-sized homes are usually 18–24kW. We size yours based on real loads.

How quickly does it come on?

Automatic standby generators detect an outage and restore power in roughly 10–20 seconds.

Do I need a concrete pad?

Most installs use a composite or concrete pad. We include the pad and anchoring in our quote.

What maintenance is required?

Annual service — oil, filters, battery check and a full load test — keeps the unit reliable and the equipment service requirements are maintained.
