Radon Testing & Mitigation Services in Northeast Ohio

---

Worried about radon in your home? Radon is a colorless, odorless, and radioactive gas—and it’s the second leading cause of lung cancer in the United States.

At Guardian Airworks, we provide certified radon testing and mitigation services across Ohio, using advanced technology and industry-leading techniques like Active Soil Depressurization (ASD). We’re fully licensed by the Ohio Department of Health and follow all NRPP (National Radon Proficiency Program) and ANSI/AARST standards to ensure your home is safe and compliant.

We use blind Continuous Radon Monitors (CRMs) to accurately measure radon levels over a 48-hour period. Our process ensures:

• Precise hourly readings
• Tamper-proof equipment
• NRPP-compliant protocols
• Fast, easy-to-understand reports

Whether you're buying or selling a home—or simply want peace of mind—we’ll provide certified results you can trust.

If high radon levels are found (4.0 pCi/L or higher), our certified technicians design and install custom mitigation systems using Active Soil Depressurization (ASD)—the most effective method for reducing radon in homes.

Our mitigation systems include:

• Professionally drilled suction points
• Sealed vent piping and inline radon fan
• Roofline exhaust system
• Sealing of foundation cracks or sump systems as needed
• Post-installation radon testing to verify effectiveness

• NRPP-Certified Professionals
• Ohio Department of Health Licensed
• Accurate Testing Using Blind CRM Devices
• Custom ASD Systems Installed to ANSI/AARST Standards
• Post-Mitigation Testing & Full Documentation
• Transferable Warranty on All Systems

We’re not just checking boxes—we’re protecting homes, health, and peace of mind. From initial testing to post-mitigation verification, every step we take is documented, compliant, and designed to meet or exceed state and national standards.

Radon is a naturally occurring gas released from soil and rock. It can enter your home through cracks, sump pits, and other openings in the foundation. Prolonged exposure increases the risk of lung cancer, especially among smokers.

• Radon causes an estimated 21,000 lung cancer deaths each year
• 1 in 3 Ohio homes test above the EPA action level
• Testing is the only way to know your home’s radon level
