The problem

Radon is the silent threat inside Colorado homes.

You can't see it, smell it, or taste it. Half of Front Range homes have it. Older homes are hit the hardest. Here's what you're actually up against.

Invisible & odorless

It's a radioactive gas. You can't see it, smell it, or taste it — only a test can find it.

Colorado's geology concentrates it

The Front Range sits on granite-rich soil that leaks radon. The entire corridor is classified EPA Zone 1.

#1 cause of lung cancer in non-smokers

The EPA attributes roughly 21,000 lung-cancer deaths per year to long-term radon exposure.

Front Range snapshot

Every major Front Range city falls in the highest-risk EPA zone.

Denver. Boulder. Fort Collins. Colorado Springs. Our geology produces some of the highest indoor radon concentrations in the United States — and newer, tighter homes trap it better than ever.

  • EPA action level: 4.0 pCi/L
  • ~1 in 2 Front Range homes test above it
  • Colorado Radon Action Month: January

The stakes

21,000 deaths a year — or a one-time fix.

Most homeowners never test. Here's the delta between doing nothing and doing the one thing that fixes it.

What drives the price (full breakdown)

The two paths

You can ignore it — or you can fix it.One decision. Fifteen hundred dollars. Here's what each path actually looks like.

If you don't test

The gas keeps building. Your family keeps breathing it.

  • Years of unknown exposure

    Radon builds up over time. Every month you don't test is another month of breathing it — unnoticed, cumulative, and directly linked to lung cancer risk.

  • Your family breathes it daily

    Kids, pets, anyone sleeping in a lower level — they're exposed more than you are. You can't see the problem, but it's hitting the people you love hardest.

  • Discovered at the worst time

    Eventually it surfaces — during a future sale, a buyer's inspection, or a doctor's appointment. Your hand gets forced on someone else's timeline, not yours.

If you test and fix

A modern mitigation system runs silently for decades. Problem handled.

  • Peace of mind in 48 hours

    A $15 kit or a pro test tells you in days whether your home is safe. Stop wondering. Stop Googling symptoms. Know for certain.

  • Family protected, 24/7

    A mitigation fan runs silently in the background for decades. One system. One pipe. One vent. Radon pulled out before it enters your breathing air.

  • Ready for anything

    Selling someday? Your home value is intact and your listing has "mitigation installed" as a feature. Staying? Your family is safe. Either way — handled.

How it works

Five steps from test to certified-clean.

Most sellers we work with go from first call to re-tested clean mitigation system in under a week. Here's the order of operations.
  1. 01

    Step 01

    Test your home

    Short-term (48-hour continuous monitor) or long-term (90-day kit). Results back in days.

  2. 02

    Step 02

    Above 4 pCi/L? You need mitigation

    That's the EPA's action level. Anything higher calls for a professional mitigation system.

    Step 03

    24-hour turnaround from our NRPP-certified team. We walk the home, not just the paperwork.

  4. 04

    Step 04

    System installed in 4–6 hours

    A licensed Colorado technician installs a sub-slab depressurization system. One visit.

  5. 05

    Step 05

    Post-install re-test

    We re-test to confirm radon is below EPA levels — most homes drop 90–99%.
