Radon in Roswell, Georgia: What Homeowners Need to Know

Roswell is one of metro Atlanta's largest and most historic cities, with a population exceeding 92,000. Located in North Fulton County along the Chattahoochee River, Roswell combines historic charm with modern amenities. However, the same granite bedrock that provides stable foundations throughout the city also creates significant radon risk.

With an average indoor radon level of 4.2 pCi/L—above the EPA's action level of 4.0 pCi/L—Roswell is classified as EPA Zone 1, the highest radon risk category. Over 17,000 homes in the Roswell area have radon levels that warrant mitigation. This makes radon testing essential for all Roswell homeowners, whether you live in a historic home near the Square or a new build in the suburbs.

Radon is the second leading cause of lung cancer in the United States. The gas is produced when uranium in granite and other rocks decays. Because radon is invisible, odorless, and tasteless, it can accumulate in homes undetected. The only way to know your home's radon level is through professional testing.

Whether you live in Historic Roswell, East Roswell, West Roswell, along the Chattahoochee, or in one of the many established neighborhoods, your property's radon levels depend on the specific geology beneath your foundation. Testing is the only way to find out.

Roswell Geology and Radon Risk

Roswell sits within the Piedmont physiographic province, characterized by granite bedrock and decomposed granite soils common throughout North Fulton County. These granites contain naturally occurring uranium that appears on National Uranium Resource Evaluation (NURE) maps. As uranium decays, it produces radon gas that can migrate into homes.

The Chattahoochee River corridor that runs through Roswell features significant granite formations. Areas near the river, along with neighborhoods in Mountain Park, Willeo, and Horseshoe Bend, often show elevated radon due to fractured rock that provides pathways for radon migration. The geology across Roswell, Alpharetta, Sandy Springs, and Milton is essentially identical, explaining the Zone 1 classification throughout the corridor.

Radon Testing Across Roswell Neighborhoods

Roswell features everything from historic antebellum homes to modern developments. Every property type on North Fulton's granite bedrock faces radon risk.

Historic Roswell Properties

Roswell's historic district features homes dating back to the 1800s. These properties often have stone foundations, basements, and crawl spaces that can allow radon entry through settling cracks and gaps.

We specialize in mitigation solutions that preserve historic character. Systems can be installed discreetly to protect your family while respecting your home's heritage.

Established Neighborhoods

East Roswell, West Roswell, and neighborhoods like Martins Landing and Big Creek feature single-family homes from the 1970s through today. Many have basements that are in direct contact with granite bedrock.

Finished basements are particularly important to test, as they're often used as living spaces where family members spend significant time.

Chattahoochee River Corridor

Properties along the Chattahoochee River in areas like Riverside, Riverwalk, and Willeo sit on granite formations that characterize the river corridor. Fractured rock near the river can provide enhanced pathways for radon.

River corridor homes often test higher for radon. The scenic location comes with geology that warrants testing and potential mitigation.

Schools, Daycares & Commercial

Roswell is home to excellent schools and numerous daycares. Children are especially vulnerable to radon exposure due to higher respiration rates and developing lungs.

We provide commercial radon testing and mitigation services for Roswell businesses, schools, and multi-family properties with full compliance documentation.

Frequently Asked Questions About Radon in Roswell, GA

Common questions from Roswell homeowners about radon testing and mitigation

Why is radon a significant concern in Roswell?

Roswell sits on granite bedrock and decomposed granite soils throughout North Fulton County. This granite naturally contains uranium that decays into radon gas. With over 17,000 homes at elevated radon levels and an average reading of 4.2 pCi/L, Roswell is classified as EPA Zone 1—the highest radon risk category. The historic nature of many Roswell homes, with older foundations, can increase radon entry points.

What is the average radon level in Roswell, GA?

Roswell has an average indoor radon level of approximately 4.2 pCi/L, which is above the EPA's recommended action level of 4.0 pCi/L. The area is classified as EPA Zone 1 (high risk). Individual homes can test significantly higher depending on foundation type, soil conditions, and construction methods—especially in historic properties.

Are historic Roswell homes at higher risk for radon?

Yes, historic homes in Roswell can have higher radon levels due to older foundation construction, more settling and cracking over time, and original building techniques that didn't account for radon. However, any home in Roswell—new or old—can have elevated radon because the underlying granite geology affects all properties. Testing is essential regardless of home age.

How much does radon mitigation cost in Roswell?

Radon mitigation systems in Roswell typically cost between $1,200 and $2,500 for standard residential installations. Historic homes may require specialized approaches to preserve architectural character. The final cost depends on foundation type, home size, and system complexity. We provide free estimates so you know the cost upfront.

What areas of Roswell have the highest radon levels?

Radon levels vary throughout Roswell based on localized geology. Areas near the Chattahoochee River, Mountain Park, and Willeo often have granite outcroppings that increase radon potential. Historic Roswell, East Roswell, and West Roswell all have documented elevated levels. Testing is the only way to know your specific home's radon level.

How long does radon testing take in Roswell?

Short-term radon tests take 48 to 96 hours and provide a snapshot of your home's radon levels. We use professional continuous radon monitors that record hourly readings for the most accurate results. For real estate transactions in Roswell, we offer 48-hour turnaround to keep deals on schedule.

Can radon mitigation systems be installed in historic Roswell homes?

Absolutely. We specialize in radon mitigation solutions that respect the architectural integrity of historic Roswell homes. Systems can be routed through closets, installed in inconspicuous locations, or vented through existing chases. The goal is effective radon reduction with minimal visual impact to your home's historic character.

Do I need radon testing when buying a home in Roswell?

Yes, radon testing should be part of any Roswell home purchase. Given the city's Zone 1 classification and extensive granite geology, elevated radon is common. Most buyers' inspections include radon testing. If elevated levels are found, mitigation can often be negotiated as part of the sale or as a seller concession.
