Radon Testing and Mitigation Services
Peerless Environmental provides radon testing and mitigation for homes, commercial buildings, schools, and properties across the Southeast.
What You Need to Know About Radon
Radon is a naturally occurring radioactive gas produced by the decay of uranium in soil and rock. It is colorless and odorless, so testing is the only way to detect it. Radon enters buildings through foundation cracks, openings, and construction joints, and long-term exposure to elevated levels is the second leading cause of lung cancer in the United States after smoking. The EPA sets an action level of 4 pCi/L, at or above which mitigation is recommended. Effective mitigation systems can significantly reduce radon concentrations below that threshold.

Radon Testing
Measure radon levels in your home or building over a defined test period.
Radon testing measures the concentration of radon gas in a building over a defined period. Results are in pCi/L. The EPA recommends action when levels reach 4 pCi/L or higher. Testing is the essential first step before any mitigation work.
Learn About TestingRadon Mitigation
Sub-slab depressurization and related systems that reduce radon concentrations to safer levels.
When testing reveals elevated radon levels, mitigation systems such as sub-slab depressurization can significantly reduce concentrations. Post-mitigation testing confirms the system is working. Documentation supports real estate transactions and ongoing compliance records.

Homeowners
Testing for new or existing homes, especially before a sale, renovation, or when moving into a property with unknown radon history.
Buyers and Sellers
Real estate transactions frequently include a radon contingency. Testing and mitigation documentation help keep deals moving.
Property Managers
Radon testing for multi-unit buildings, basements, and ground-floor spaces where tenant safety and compliance documentation are needed.
Commercial and Institutional
Schools, office buildings, and healthcare facilities with ground-floor or basement occupancy where radon risk should be assessed and documented.
New Construction
New builds benefit from radon-resistant construction practices and post-construction testing to confirm baseline levels.

Common Questions
What is radon and why is it a concern?
Radon is a naturally occurring radioactive gas produced by the breakdown of uranium in soil, rock, and water. It is colorless and odorless. Testing is the only way to know your exposure level. Radon enters buildings through cracks in foundations, construction joints, and openings around pipes. Long-term exposure to elevated radon levels is the second leading cause of lung cancer in the US after smoking.
How do I know if my home has high radon levels?
You can only know through testing. Radon cannot be seen, smelled, or detected without a test. Short-term tests (48 hours or more) provide a baseline reading. Long-term tests go further. They give a more accurate annual average. The EPA action level is 4 pCi/L. At or above this level, mitigation is recommended.
What level of radon is considered unsafe?
The EPA recommends taking action when indoor radon levels reach 4 pCi/L or higher. Context matters. The average indoor radon level in the US is about 1.3 pCi/L. Levels between 2 and 4 pCi/L may warrant consideration depending on property use and occupant risk factors.
How does radon mitigation work?
The most common method is sub-slab depressurization (SSD), which involves installing a vent pipe through the foundation slab and using a fan to draw radon gas from beneath the building and exhaust it safely outside. This method is effective for most homes and commercial buildings. Post-mitigation testing confirms the system is reducing levels.
