Radon Mitigation
Make an invisible risk a non-issue
Radon can’t be seen or smelled, but it can be dealt with. If your test results are high, the next step is simple: mitigation. Our mitigation systems use gentle suction below your home to capture radon before it enters your living space, then safely vent it above the roof. Installation is clean and discreet. Afterward, we run a 48-hour test to confirm the reduction and explain how and when to re-test. We focus on clear, reliable numbers you can trust.
How Radon Mitigation Works
Radon reduction works by creating gentle, steady suction under your home. This way, soil gas is collected and vented outside, above the roofline, before it can get into your living spaces. We tailor our approach to your foundation type.

Living with Your Radon System: What to Expect
A good mitigation system is “set it and forget it.” Once installed, it works on its own. Add a couple of seasonal check-ins for peace of mind.
Quiet, Always-On Fan
Your exterior radon fan runs 24/7. It's quiet, energy-efficient, and safe to leave on year-round. Don't switch it off.
Simple Status Check (Manometer)
The U-tube gauge on the pipe should show the two liquid levels at different heights. This means the fan is working correctly. If the levels are even, the system is not drawing air. Please call us.
Optional Audible Alarm
If we installed a radon alarm, it will alert you if power is lost or suction drops. Test the alarm button twice a year.
Seasonal Ups & Downs Are Normal
Radon levels can be slightly higher in winter because windows are closed and airflow in your home changes. Your system is built to handle these changes. We still recommend testing your radon levels about every 2 years to track performance.
After Storms or Power Outages
When power returns, the fan will start running again on its own. You might notice a brief increase in radon levels on a follow-up test, but this usually goes back to normal as the system starts working again.

When to Call Radon Control
Let's Look at Your Manometer
Look at the numbers printed next to each column and compare them to the install-day baseline we wrote on your sticker.
What the numbers mean:
30-Second Seasonal Check:
- Glance at the gauge and compare the reading to your baseline sticker.
- Step outside: make sure the exhaust isn’t blocked.
- Listen for the fan’s gentle hum.
- If anything seems off or the gauge reads the same on both sides, contact us, and we’ll walk you through the next steps.
After Install: Post-Test & Ongoing Re-Testing
Verify the Drop
Once your mitigation system is installed, we run a 48-hour test with your windows closed and normal entry and exit. We set up a continuous monitor on the lowest livable floor, collect it after 48 hours, and send you a simple summary of your average pCi/L result along with the next steps. If the results are not where we want them, we will troubleshoot by sealing more gaps, adjusting the fan, or adding another suction point, and then test again.
Keep It Documented
You’ll receive a recap and lab-verified results you can save for your records or real estate needs.
Re-Test Over Time
Check your U-tube manometer once a month.
If both columns are level at “0,” it means there is no suction. If you hear the alarm, the fan might be off, a breaker could have tripped, or there may be a blockage. If the fan is running and you do not find a blockage, please give us a call.
Frequently Asked Questions
Indiana homeowners ask us these radon mitigation questions every day. Here are some answers to those questions about noise, post-mitigation testing, and more.
What is a radon mitigation system?
A system (and set of steps) designed to reduce indoor radon. The EPA recommends fixing at 4.0 pCi/L or higher.
Do I need testing after installation?
Yes. Do a post-mitigation test (starting after system install) and retest in the future (at least every 2 years and after major home alterations).
How low can mitigation bring levels?
Some systems can reduce radon by up to 99%. With today’s technology, most homes can be reduced to 2.0 pCi/L or below.
How much does mitigation cost?
For most homes, the cost is similar to other common repairs. The typical price is about $1,200, but it can range from around $500 to $2,500 depending on your home’s size, layout, and the method used.
Who should I hire for radon mitigation?
Hire a qualified contractor like Cut ‘N Dry Waterproofing, as radon mitigation requires specialized skills and equipment. Many states license or certify radon professionals, and the EPA also recommends choosing trained, certified providers.
What are "radon-resistant" features (for new builds/renovations)?
These features include a gas-permeable layer, plastic sheeting, sealed openings, a vent pipe to the roof, and a junction box for a future fan. They are simple, affordable, and can also help control other soil gases and moisture.
If my home was built with radon-resistant features, do I still need to test?
Yes. Every home should be tested after people move in, even if it was built with radon-resistant features.
Will the system be noisy or an eyesore?
Systems use a quiet exterior fan with tidy, code-compliant piping; inside, you’ll see a small gauge (manometer) to check suction. An alarm can be added to let you know if the fan stops running.
