Working smoke and carbon monoxide detectors are the cheapest life-safety upgrade you will ever make, and in Denver they are not optional. Colorado law requires CO alarms in every home with a fuel-burning appliance or attached garage, and Denver's residential code calls for interconnected smoke alarms on every level, inside each bedroom, and outside every sleeping area. Denver Power Electric installs, replaces, and interconnects hardwired detectors so that when one sounds, they all sound, giving your family the seconds that matter most.

Battery-only units are better than nothing, but hardwired, interconnected detectors are the gold standard, and they are what inspectors look for when you sell or remodel a Denver home. Many of the older bungalows in Wash Park, Platt Park, and Berkeley were never wired for interconnected alarms, and 1990s-era detectors in Highlands Ranch and Centennial are now well past their 10-year replacement life. If your detectors chirp at 3 a.m., yellow with age, or predate your kids, it is time. We can tie new alarms into your existing circuits, and if your wiring is dated we will tell you honestly whether a rewiring or panel upgrade should come first.

Carbon monoxide deserves special attention along the Front Range. At Denver's mile-high elevation, gas furnaces, water heaters, and fireplaces burn less efficiently, and a cracked heat exchanger or blocked flue can push CO into living spaces faster than you would expect. Sealed-up, energy-efficient homes trap that gas. We place CO alarms where the experts recommend, pair them with your smoke detection, and can fold this work into a broader home electrical inspection or energy efficiency upgrade.

Our licensed master electricians install proven hardwired models from Kidde, First Alert, and BRK, including combination smoke/CO units and photoelectric alarms that resist nuisance tripping from cooking and steam. Every install includes:

  • Code-correct placement on each level, in and outside bedrooms
  • Full interconnection so all alarms trigger together
  • 10-year sealed battery backup that survives power outages
  • Testing of every device and a walkthrough with you
  • Smart-alarm options that text your phone, perfect to pair with smart home electrical

We have served Denver since 2009, hold CO Master Electrician License #ME.0047213, are fully insured, and back our work with flat-rate, upfront pricing, so you know the cost before we start. Whether you need two detectors swapped or a whole-home system in a new finished basement, we will get it done right, on code, and on time.

FAQ

Questions, answered

How often should I replace smoke and CO detectors in my Denver home?

Smoke detectors should be replaced every 10 years and CO detectors every 5 to 7 years, regardless of whether they still beep. Check the manufacture date printed on the back of the unit. If yours is older or you cannot find a date, it is safest to replace it, and we can swap a whole home's worth in a single visit.

Does Denver code require hardwired interconnected smoke alarms?

Yes. For new construction and most remodels, Denver requires hardwired, interconnected smoke alarms on every level, inside each bedroom, and outside sleeping areas, all with battery backup. Existing homes are often grandfathered, but if you are finishing a basement or selling, an inspector will expect compliant detection. We bring your home up to current code.

Why are carbon monoxide detectors so important in Colorado?

Colorado state law requires CO alarms in homes with fuel-burning appliances or attached garages. At Denver's altitude, gas furnaces and water heaters burn less efficiently and tightly sealed modern homes trap any CO that leaks, so detection is genuinely a life-safety issue here, especially through the long heating season.

How much does it cost to install smoke and CO detectors in Denver?

A single hardwired detector swap typically runs $90 to $175 installed, while a full-home system of interconnected smoke and combo CO alarms usually lands between $400 and $900 depending on how many devices and whether new wiring is needed. We give a flat, upfront price before any work starts.

Can you connect smoke detectors to my phone or smart home?

Absolutely. We install smart hardwired alarms that send alerts to your phone when they detect smoke or CO, even when you are away from home. They integrate with most smart home platforms, and we often pair this with other smart home electrical work so your whole system talks together.
