Troy, Missouri Is Raising the Standard on Radon Safety

The City of Troy is taking a major step toward protecting homeowners and buyers by advancing radon control requirements tied to home inspections and construction standards.

As outlined in the latest Board of Aldermen agenda, the city is moving to adopt IRC Appendix F (Radon Control Methods) into local code 



What This Means for Homeowners & Real Estate Transactions

• Increased focus on radon testing during home sales
• Stronger push for radon mitigation systems in new and existing homes
• Greater accountability for indoor air quality and long-term health protection
• More deals requiring fast, reliable radon results and mitigation solutions



Where Radon Ninjas Comes In

Radon Ninjas is already built for this.

We operate at the level these new standards demand:

• Certified radon testing for real estate transactions
• Precision-built mitigation systems (not cookie-cutter installs)
• Clean, code-conscious installations that pass inspection the first time
• Fast turnaround to keep deals moving
• Post-mitigation verification for documented compliance



This Is Not a Trend — It’s the Direction of the Industry

Municipalities don’t adopt radon standards unless there’s a real risk.

Troy is signaling what’s coming next across Missouri.

Homeowners, agents, and investors who move early will avoid delays, failed inspections, and last-minute negotiations.



If You’re Buying, Selling, or Managing Property in Troy:

Don’t wait until it becomes a problem in the middle of a deal.

Get ahead of it.

Is your mitigation system only pretending to work? If the U-tube manometer changed, the fan is noisy, or a recent retest came back high, don’t assume a simple swap will fix it. Radon Ninjas takes a diagnostic-first approach: we inspect fan operation, manometer vacuum, slab and sump seals, pipe routing, and electrical supply before recommending repairs or replacement. That ensures the repair restores verified radon control—not just a spinning motor.

Serving Wentzville and eastern Missouri communities, we handle fan replacement, system repair, and post-repair verification so real-estate timelines and homeowner safety aren’t left to chance. Call 636-336-6312 to schedule a diagnostic visit or learn more: https://wix.to/yVq3vd3

💀 The Real Horror: Lung Cancer from Radon
By CNG Radon | cngradon.com | (636) 336-6312

It’s not about scare tactics. It’s about facts:
• Radon is the #2 leading cause of lung cancer in the U.S.
• It’s the #1 cause among non-smokers.
• The EPA, CDC, WHO, and the Surgeon General all warn of its danger.
• Elevated levels have been found in every U.S. state.
• The only way to detect it is with a radon test.

❗ Don’t ignore this invisible threat. Take action now.



🛠️ What You Can Do:
• Test your home with a radon test kit or schedule a professional inspection.
• Install a mitigation system if levels are 4.0 pCi/L or higher.
• Encourage your friends and family to test.
• Spread awareness at PTA meetings, real estate offices, and HOA gatherings—we’re happy to speak at events.

Radon mitigation systems are effective and affordable, typically costing less than $1,300. These systems create negative pressure under your foundation, pulling the gas out before it enters your living space.

Don’t let an invisible killer haunt your home.
Protect your family.

👻 Radon vs. Ghosts: “The Dark Basement”
By CNG Radon | cngradon.com | (636) 336-6312

The night before your housewarming party, you’re prepping alone. You head to the basement to grab decorations. You’ve always thought the basement felt… off.

The lights flicker.
The switch doesn’t work.
You grab what you need—but then hear it:
A whisper.
Your name.
A shadow.
A presence behind you.
You sprint upstairs, terrified…

Radon is more dangerous than ghosts.

Fear of basements is common. Movies, stories, and folklore have conditioned us to associate dark, unfinished spaces with paranormal activity. But while there’s no scientific proof of ghosts, radon is very real—and basements are the most likely place to find it.

Radon gas seeps up from the soil surrounding your home’s foundation. It can infiltrate basements, crawlspaces, bedrooms, home gyms, and entertainment rooms without a trace.

In Missouri, 1 in 4 homes has dangerously high radon levels. In Illinois, it’s over 40%. Testing is the only way to know if your basement is hiding more than just old boxes and bad memories.

🛠️ What You Can Do:
• Test your home with a radon test kit or schedule a professional inspection.
• Install a mitigation system if levels are 4.0 pCi/L or higher.
• Encourage your friends and family to test.
• Spread awareness at PTA meetings, real estate offices, and HOA gatherings—we’re happy to speak at events.

Radon mitigation systems are effective and affordable, typically costing less than $1,300. These systems create negative pressure under your foundation, pulling the gas out before it enters your living space.

🦈 Radon vs. Sharks: “Something Is Lurking in the Water…”
By CNG Radon | cngradon.com | (636) 336-6312

You finally take that long-overdue beach vacation. The sun is shining, waves crashing. You wade into the water, enjoying the moment—until something brushes your leg. You freeze.
Then you remember the small cut on your calf. Is blood leaking into the water?
Is a shark tracking you?
You panic.
It’s too late…

Radon is more dangerous than sharks.

Sure, shark attacks are terrifying, but the actual risk is minimal. According to National Geographic, there are an average of just 19 shark attacks per year in the U.S., with only 1 fatality every two years.

Compare that to the 21,000 annual radon deaths, and the silent threat lurking in your home becomes the real predator.

And yes—radon can even be in your water. Especially for homes on well water, radon can enter the air through showers, dishwashers, or faucets—further increasing your risk.

🛠️ What You Can Do:
• Test your home with a radon test kit or schedule a professional inspection.
• Install a mitigation system if levels are 4.0 pCi/L or higher.
• Encourage your friends and family to test.
• Spread awareness at PTA meetings, real estate offices, and HOA gatherings—we’re happy to speak at events.

😱 Radon vs. Spiders: “Don’t Sleep With Your Mouth Open”
By CNG Radon | cngradon.com | (636) 336-6312

You spent all day cleaning and rearranging your bedroom. After hours of work, you finally crawl under the covers, exhausted. You drift off to sleep, unaware that when you moved your nightstand, you disturbed something…

A tickle on your leg.
Then your side…
Your chest…
Your neck…

You’re sound asleep—mouth open—when a black widow spider, carrying babies on her back, climbs onto your lips…

Radon is more dangerous than spiders.

Even thinking about a spider in your mouth is terrifying. But let’s look at the facts. According to Animal-Related Fatalities in the United States—An Update by Ricky L. Langley, MD, MPH, there were 66 deaths from spider bites between 1991 and 2001.

Compare that to over 200,000 radon-related lung cancer deaths in the same span, and the true threat becomes clear.

Even creepier: your highest exposure to radon is likely while you sleep. Since radon is heavier than air, it collects near the ground—and if your bed is on a low frame or in a basement bedroom, you may be breathing in elevated levels for 6–8 hours a night… every night.

🛠️ What You Can Do:
• Test your home with a radon test kit or schedule a professional inspection.
• Install a mitigation system if levels are 4.0 pCi/L or higher.
• Encourage your friends and family to test.
• Spread awareness at PTA meetings, real estate offices, and HOA gatherings—we’re happy to speak at events.

The Real Haunting in Your Home Isn’t Ghosts… It’s Radon.
By CNG Radon | cngradon.com | (636) 336-6312

Your home may be haunted by something even more frightening than ghosts or goblins. But what is it—and why should it scare you?

You can’t see it. You can’t smell it. You can’t taste it.
Yet it could be lurking in your home right now, silently threatening your health.

That invisible killer? Radon.

Radon doesn’t rattle chains or whisper “Boo!” in the night—but it is the #1 cause of lung cancer among non-smokers, responsible for an estimated 21,000 American deaths every year, according to the EPA.

This radioactive gas is naturally released when uranium in soil and rock breaks down. And without a radon test, you’d never know it’s there.



🛠️ What You Can Do:
• Test your home with a radon test kit or schedule a professional inspection.
• Install a mitigation system if levels are 4.0 pCi/L or higher.
• Encourage your friends and family to test.
• Spread awareness at PTA meetings, real estate offices, and HOA gatherings—we’re happy to speak at events.

Radon mitigation systems are effective and affordable, typically costing less than $1,300. These systems create negative pressure under your foundation, pulling the gas out before it enters your living space.
