Radon Solutions Built for Central Ohio Homes

From initial testing to final verification, we handle every step of the radon mitigation process — certified, thorough, and backed by results.

Radon Testing

Know your numbers before you act.

Accurate radon measurement is the foundation of everything we do. We deploy certified short-term and long-term test devices in the lowest livable area of your home — typically the basement or first floor — and follow EPA-approved protocols throughout. You'll receive a written report with your radon level in picocuries per liter (pCi/L), a clear explanation of what it means, and our honest recommendation for next steps.

Mitigation System Installation

A permanent fix, installed in a single day.

Sub-slab depressurization (SSD) is the most effective and widely recommended method for reducing radon in homes. We design a system specific to your home's foundation type — slab-on-grade, basement, or crawl space — and install it cleanly and efficiently. A sealed PVC pipe runs from beneath your foundation to above the roofline, and a continuously running fan draws radon out before it can enter your living space. Every installation is code-compliant and built to last.

Post-Mitigation Verification

We don't leave until the numbers prove it worked.

After your mitigation system is installed, we return to re-test your home's radon levels. This post-mitigation test confirms that your system is performing correctly and that radon has dropped below the EPA action level of 4 pCi/L. If levels are still elevated, we diagnose and adjust the system at no additional charge. You'll receive a final written report documenting your before and after results.
