Radon Testing
Radon is an odorless, invisible, radioactive gas that can enter your home from the ground through cracks in the foundation. A known human carcinogen, radon is the second leading cause of lung cancer.
Pennsylvania has one of the most serious radon problems in the United States. Approximately 40% of homes tested in Pennsylvania have radon levels above the Environmental Protection Agency’s action guideline of 4 picocuries per liter (pCi/L).

Why is a certified radon professional better?
1. Superior Accuracy: Professionals use Continuous Radon Monitors (CRM), which provide hourly digital readings rather than a single average number from a charcoal canister. This helps identify fluctuations caused by weather or ventilation.
2. Real Estate Credibility: Professional results are often required in property sales. A certified report can serve as legal leverage to negotiate home prices or require seller-funded mitigation.
3. Faster Results: While mail-in DIY kits can take weeks for laboratory processing, professional monitors often provide results immediately after the 48-hour testing period.
4. Expert Placement & Knowledge: Certified inspectors understand building science and identify specific entry points (like cracks or sump pumps) where radon might be seeping in.
5. Tamper Resistance: Professional equipment often includes sensors to detect if the device has been moved or if windows were opened to skew results—features not found in DIY kits.
