Radon is a radioactive gas with no color, smell, or taste. It forms as uranium naturally breaks down in soil and rock, then moves through the ground and can enter your home through cracks and other foundation openings.
Indoors, radon can accumulate. Breathing it over time increases lung cancer risk. Testing reveals your home’s level so you can make an informed decision about reducing exposure.
Radon is the leading cause of lung cancer among people who do not smoke, and the second leading cause overall.
Radon is invisible, tasteless, and odorless. Testing is the only way to know your home’s radon level.
The Ohio Department of Health has estimated that about half of Ohio families live in homes with elevated radon levels. Testing is the only way to know your home’s level.
WHO recommends a national annual-average residential reference level of 100 Bq/m³—about 2.7 pCi/L—where achievable. This differs from the U.S. EPA action level.
Fix homes at 4.0 pCi/L or above, and consider reducing radon between 2.0 and 4.0 pCi/L. There is no known safe level of radon exposure.
You don’t need to know everything about radon to get started. Just tell us a little about your home.
Share your address, any test results, and what you need help with. Have a real-estate deadline? Let us know.
We review your property’s needs and discuss the appropriate scope, estimate, and scheduling options.
Coordinate the work, understand your system, and confirm the post-installation testing plan for your project.
From measuring radon levels to installing a mitigation system or repairing an existing one, here are three examples of the services we provide.

Measurement equipment helps determine the radon level in your home and informs the next step.

A vent pipe and fan draw soil gas from beneath the home and discharge it outdoors to help reduce radon entry.

Sealing a sump pit is one way we can address soil-gas entry points when servicing or repairing a radon system.

We work with homeowners, homebuyers, sellers, realtors, builders, and property professionals. Whether you need a test, a new system, a repair, or help planning a project, our office is here to help.
Share your test results, system concerns, or project details. We’ll help you understand the next step.

Explore EPA radon resourcesRadon is a naturally occurring radioactive gas released as uranium in soil, rock, and water breaks down. It has no color, smell, or taste. It can enter a building through foundation cracks, gaps around pipes, and other openings. Testing is how you find out your home’s radon level.
After a new mitigation system is installed, arrange a post-installation test within 30 days, but no sooner than 24 hours after the system is operating. EPA recommends retesting at least every two years to confirm levels remain low. Follow the testing instructions for your property and contact our office to coordinate your next test.
A common approach uses a vent pipe and a specialized fan to draw soil gas from beneath the foundation and discharge it outdoors. This helps reduce radon entering the building. The design depends on the foundation, crawlspace, layout, and conditions at your property.
Breathing radon over time increases the risk of lung cancer. Radon can build up in new or older homes, with or without a basement. Because you cannot detect it by sight or smell, testing is important. Learn more about radon and health through the EPA’s radon resources.
Check the system’s warning device, often a U-shaped manometer mounted on the vent pipe. Unequal fluid levels indicate a pressure difference; compare the reading with the normal reading documented for your system. Equal levels, a changed reading, or an alarm are reasons to contact our office. The gauge does not measure radon and cannot confirm the radon level is low—only a radon test can do that.
No. We do not require a radon test before scheduling an estimate. If you already have test results, share them with our office along with the property address and any timing requirements.
Yes. We visit the property in person to review its conditions and prepare a mitigation proposal suited to the building. Once you accept the proposal, our office can discuss installation scheduling and availability.
pCi/L means picocuries per liter of air. It is a measure of radioactive activity in a volume of air and is used to describe radon concentration. Your radon test report uses this unit to show the measured level.
Encapsulation covers exposed crawlspace soil with a durable vapor barrier, with seams and openings sealed as appropriate to the design. It can help manage ground moisture and can be part of a radon mitigation approach. Our team reviews your crawlspace and explains the barrier, sealing, and any mitigation work suited to the property. Encapsulation is not a substitute for correcting drainage problems or active water entry.
Send the report when you contact us. Include the property address, the test location, and any real-estate deadline so our office can discuss the appropriate next step.
The scope depends on your foundation, home layout, system routing, and site conditions. Contact our office for a property-specific estimate and a clear description of the proposed work.
Yes. Our radon repair services include sump pit sealing, fan replacement, and repairs to existing mitigation systems. Tell us what you have noticed and share available photos or recent test results.
