Safe, Reliable Electrical Work — Done Right the First Time

Common signs include frequently tripping breakers, flickering lights when appliances run, a panel that's warm to the touch, or a fuse box instead of a modern breaker panel. Homes built before 1980 with original electrical systems often can't safely support today's energy loads. We offer free panel assessments — give us a call and Marcus or Diana can usually walk you through a quick evaluation over the phone before scheduling a site visit.

Yes. Greenfield Electric holds a Colorado Master Electrical Contractor license, and every project is fully insured with general liability and workers' compensation coverage. Marcus is personally licensed as a Master Electrician — the highest credential the state issues — which means every permit we pull is backed by 20 years of professional standing with Denver Building Services.

Always. We pull permits for every project that requires one — panel upgrades, rewires, EV charger installations, and most commercial work. We know some contractors skip this step to save time, but unpermitted electrical work creates serious problems when you sell your home or file an insurance claim. We handle the permit process from start to finish, including scheduling the final city inspection.

We install all major Level 2 home chargers including Tesla Wall Connector, ChargePoint Home Flex, Enel X JuiceBox, Grizzl-E, and Emporia. We'll help you pick the right unit for your vehicle, your panel capacity, and your budget. We're also familiar with all current Xcel Energy and Colorado state EV rebate programs and can help you apply to maximize your savings.

For a typical Denver single-family home — say, 1,500 to 2,500 square feet — a full rewire usually takes three to five days. We use low-impact fishing techniques to run new wire through existing walls wherever possible, which significantly reduces drywall repair. Marcus will give you a realistic timeline during the estimate, and we stick to it.

Yes, we provide free on-site estimates for all residential and commercial projects. We don't do ballpark quotes over the phone for complex jobs because we'd rather give you an accurate number after seeing the actual work than hit you with a surprise change order later. Most estimates take 30 to 45 minutes and we can usually get out within a few business days of your call.
