Standby generator installation

Wind events, ice storms, and wildfire-season shutoffs put parts of Douglas County dark for hours to days. An automatic standby generator sits beside the house on a pad, runs on natural gas or propane, and starts itself within seconds of an outage through a transfer switch. We size it to what you actually need to keep on rather than selling you a unit that spends its life idling.

Do any of these sound familiar?

Signs you need this

01

You are on a well or a septic pump

No power means no water and no drainage. Franktown, Elizabeth, Sedalia and rural Parker acreage feel outages very differently to a city lot.

02

Someone depends on powered medical equipment

That moves a generator from a convenience to a necessity, and it changes how we size and site it.

03

You lose the fridge, freezer, and sump every time

The cost of spoiled food and a wet basement adds up quickly against the cost of the install.

04

You work from home

A multi-hour outage is a lost workday. A standby unit turns it into a non-event you barely notice.

What it costs

$6,500to$24,000

What moves the price
generator kW, whole-house versus essential-circuits transfer switch, gas line and pad work, and distance from the meter.
What is included
the generator, transfer switch, pad, electrical and gas connection, permit, inspection, and startup.

Estimated range, reviewed regularly. Your exact price is fixed in writing before any work begins.

What the price covers

  • A load assessment covering what must stay on and what would be nice
  • Whole-house or essential-circuits transfer switch, chosen with you
  • The pad set, and siting that meets clearances, noise, and HOA rules
  • Electrical and gas permits filed, and both inspections attended
  • Commissioning and a load test before we hand it over
  • A walkthrough of the weekly self-exercise cycle and what to expect

How the job goes

  1. 1

    We do a load assessment covering what must stay on, what would be nice, and what that means in kW.

  2. 2

    We choose whole-house or essential circuits, site the pad for clearances and noise, and confirm the gas supply.

  3. 3

    We pull the electrical and gas permits, set the pad, and wire the transfer switch at the panel.

  4. 4

    The jurisdiction inspects, we commission and test it under load, and show you how it exercises itself weekly.

Permits and inspection

Standby generators need an electrical permit and usually a mechanical or gas permit, plus inspection. Some HOAs in Pradera, Castle Pines and Castle Rock have placement and screening rules. We handle the jurisdiction, and our Douglas County HOA guide covers the association side.

Jud and his team have done a ton of work at our house over the years. Most recently hooking up our hot tub. He’s replaced our panel, set us up with a generator and much more. Jud is responsive, prompt, reasonably priced, and he’s genuinely a nice guy. Finding contractors who will respond and actually show up is hard, but I never worry when I have an electrical issue. Jud is the best!

We did not have power coming through a circuit in our garage. When I called on a Friday morning, I fully expected we would have to wait until after the weekend for an electrician to come out. But Jud was able to come diagnose the issue within just a few hours! I was very impressed, and so happy that he was also able to fix the problem very quickly. Jud was very professional, explained everything so well, and is very trustworthy.

I chose AllSafe Electric because their project proposal was the most detailed and comprehensive of those I received. Once the project began, I was thoroughly impressed by their expertise, workmanship, and attention to detail. An excellent experience. Most highly recommended.

We had a great experience with Allsafe Electric. At the initial consult, we discussed the work we wanted done, and Jud expertly explained the options for how he could get it done clean and cost effective. He didn't try to push or upsell anything. His estimate was clear and fair, and he was flexible when we asked to reschedule the date of work. Once scheduled he showed up right on time and did clean, quality work. The work included relocating our EV charger hookup, adding a new outlet, installation of both an interior and exterior ceiling fan box, a new ethernet cable plug, and a new outlet for an induction cooktop. Professional, communicative, and easy to work with. We'd absolutely use Allsafe again and recommend Jud to anyone in the Parker area.

Over the past couple years we have been stumbling through the repairs of construction defects. Many of those defects involved electrical. Along with new defects, we still have some old electrical that was not made up to date by the previous subcontractor. Judd and the AllSafe crew have helped navigate and make repairs as we find them. It’s been such a relief to have knowledgeable electricians help keep our family safe and regain some of our creature comforts. We appreciate knowing someone around we can count on for help. Thank you for your patients and empathy for us during all this. We really appreciates good people. Thank you. The Black Family

All Safe is a fantastic electrician company. They are great communicators as to when they will arrive and work in a clean orderly fashion. They installed new lighting fixtures, replaced a broken GFI, replaced switches, repaired an outlet. They did a great job I highly recommend them.

Common questions

What size generator do I need?

It depends on whether you want the whole house or just essentials such as the furnace, fridge, well, sump, and some lights and outlets. We run the numbers on your actual loads rather than quoting a default 22kW.

Natural gas or propane?

If you have natural gas at the house that is usually simplest, with no tank and no refills. Propane makes sense on acreage without gas service. We confirm the meter or tank can supply the demand.

How much does a whole-house generator cost in Colorado?

Installed, most residential projects land in the range above. The spread is real, because a small essential-circuits system and a large whole-house unit with a long gas run are very different jobs.

How loud is it, and how close to the house can it go?

Modern units are about as loud as an AC condenser. Placement has to meet clearance from windows, doors, and the meter, plus any HOA rules, and we site it to satisfy all three.

Areas we cover for standby generators

Where we do standby generators

We handle standby generators across Parker and the surrounding south metro. That includes Parker, Castle Rock, Highlands Ranch, Lone Tree, Centennial and The Pinery, plus every other town on our service area page. Each town page lists its own permit authority and electric utility, which genuinely differ across Douglas, Arapahoe and Elbert counties.
