Homeowners in Chicago’s North Shore and the northwest suburbs are paying closer attention to radon—an odorless, invisible gas that can seep into buildings from the soil. Because radon exposure is a known health risk, many families are taking steps to measure levels and, when needed, install radon control systems.
Radon control is designed to prevent the gas from accumulating indoors. Instead of relying on short-term fixes, mitigation systems target the source by changing how air moves beneath and around a home’s foundation, helping lower radon concentration over time.
What a radon control system typically does
Most modern solutions focus on drawing radon-laden air away from the soil and venting it outdoors. The most commonly used approach is active soil depressurization, which uses a fan connected to piping installed at the foundation to reduce pressure beneath the slab or crawlspace.
Depending on the home’s design, additional components may be used to improve performance, such as sealing entry points and configuring vent paths to maintain safe, effective discharge.
Why testing still matters
Radon levels vary significantly by location, season, and building characteristics. Specialists emphasize that the best mitigation decisions begin with measurement—using short-term or long-term testing methods—so homeowners understand whether control is warranted and can verify results after installation.
Follow-up testing is typically recommended to confirm that the system is achieving the desired reduction and that the home remains safer over time.
Choosing a provider in the North Shore and northwest suburbs
When selecting a radon mitigation contractor, residents are encouraged to look for experience with local building conditions and a clear plan for system design. A reputable provider should explain options, review test results, and describe how the system will be installed, monitored, and validated.
For Chicago-area households, a well-designed radon control system is not only about installation—it’s also about long-term verification, ensuring the mitigation strategy performs as intended.
Homeowners who suspect elevated radon levels can start by arranging a radon test, then consulting with local professionals to discuss whether mitigation is necessary and which system configuration fits their property.

Protect Your Family From Harmful Radon Gas Accumulation
Radon is a naturally occurring, invisible, odorless, and tasteless radioactive gas produced by the decay of uranium in Illinois soil and bedrock. It enters homes through foundation slab cracks, sump pits, construction joints, and crawl spaces. According to the EPA and IEMA (Illinois Emergency Management Agency), radon is the #1 cause of lung cancer among non-smokers. Because Chicagoland sits in high-risk radon zone regions, active sub-slab depressurization is the most effective way to protect your indoor air quality. Call our licensed radon mitigation specialists at (224) 754-1984 if you notice or experience any of these situations:
Radon Test Results Exceeding EPA Action Levels: Continuous monitoring or radon test kits indicating levels at or above 4.0 pCi/L (picocuries per liter).
Buying or Selling a Property (Real Estate Transactions): Home inspection contingency requiring certified radon reduction system installation prior to closing.
Unsealed Basement Sump Pits & Floor Cracks: Open sump basins, floor drain openings, or visible foundation wall cracks allowing soil gas seepage.
Finished Basements Used as Living Spaces: Bedrooms, home offices, or playrooms located below-grade with limited natural air exchange.
Aging or Failed Existing Radon Fan: Existing radon mitigation fan humming loudly, vibrating, or showing zero differential pressure on the U-tube manometer.

U-Tube Manometer & Post-Mitigation Test: Installing differential pressure indicators, system safety warnings, and initiating a 48-hour post-installation radon verification test.
Frequently Asked Questions: Radon Control Systems
Q: What is a safe level of radon gas in a home?
A: The EPA recommends taking action if radon levels test at 4.0 pCi/L or higher. However, because radon has no safe exposure threshold, goal levels below 2.0 pCi/L provide optimal indoor health protection.
Q: How long does a radon mitigation fan last?
A: Quality radon inline fans (such as RadonAway or Fantech) are designed for continuous 24/7 operation and typically last between 5 to 10+ years. Replacing a failed fan is quick and straightforward.
Q: How do I know if my radon mitigation system is working properly?
A: Every installed system includes a clear U-tube manometer mounted on the PVC pipe. If the fluid levels are uneven, the fan is creating proper vacuum suction beneath your slab. If the fluid levels are even, the fan has lost power or failed.
Q: Will installing a radon system lower my basement humidity?
A: Yes. Because the suction system draws air and moisture vapor out from beneath the concrete slab before it enters your home, many homeowners notice a significant decrease in damp basement odors.
