Seven questions worth asking any installer before you sign, each paired with how many of the 3 installers listed on this page already meet it, based only on what we've verified or what each business states in its own profile. A missing answer here doesn't mean an installer can't do it, only that it isn't on record yet, so ask.
A standby generator ties into your home's main electrical panel through a transfer switch, which makes it licensed electrical work. A license check is the one thing every listing on LumoWatt must pass.
On this page: 3 of 3 have a license we checked against the state board.

Manufacturers train and authorize dealers for their own equipment. Warranty registration, extended warranty offers, and parts access often run through an authorized dealer.
On this page: None are listed as certified for a specific brand yet, ask which brands they are authorized to install.
Most standby installs need an electrical permit, and often a gas or fuel permit as well. An installer who handles both saves weeks of back and forth with the city.
On this page: None mention permit help in their profile, ask whether it is included in the quote.
Standby generators need oil, filter, and battery service on a schedule. Buying from someone who also maintains and repairs what they install avoids a hunt for service later.
On this page: None mention maintenance or repair in their profile, ask who handles service after install.
The moment a generator fails to start is usually the middle of a storm. Emergency availability matters more here than for most home services.
On this page: None advertise 24/7 emergency service in their profile, ask about after-hours response.
The manufacturer warranty covers the generator itself. The installer's own workmanship warranty covers their wiring, pad, and gas line work, and terms vary widely, so get it in writing.
On this page: None have published warranty details here yet, ask for the workmanship warranty in writing with your quote.
A whole-home standby system is a major purchase. Installer financing is one option, but compare it against a home equity line or personal loan rate.
On this page: None list financing on their profile yet, ask when you request a quote.

The only requirement to appear on this page is a checked state electrical license, confirmed against the state licensing board as part of our approval process, that's why every listing above shows "License checked." Installers are listed alphabetically by default, not ranked by quality, and no installer pays for placement in that order. LumoWatt does not sell ranking. If paid placement is introduced, it will be clearly labeled and will not change the standard list order. Use the sort dropdown above to re-order the list yourself by years in business or how recently we checked a listing. See our editorial policy and listing standards & verification methodology for the full details.

Colorado sees severe winter storms and blizzards, spring hail, and increasingly wildfire-driven Public Safety Power Shutoffs from Xcel Energy in high fire-risk areas, on top of routine grid strain. This combination of extreme-weather risk (rather than a single dominant driver like desert heat or hurricanes) is what pushes standby generator demand across the Front Range.
