Radon in Peachtree Corners, Georgia: What Gwinnett County Homeowners Need to Know
Peachtree Corners is a city of over 42,000 residents in Gwinnett County, Georgia's second most populous county with more than 957,000 people. Incorporated in 2012, Peachtree Corners covers approximately 16 square miles and is home to the 500-acre Technology Park, The Forum commercial district, and established residential neighborhoods with a median home value around $550,000.
Gwinnett County is classified as EPA Zone 1, the highest-risk category for radon, with a predicted average indoor screening level exceeding 4.0 pCi/L. According to UGA Extension data, 22% to 28% of homes tested in Gwinnett County had radon levels above the EPA action level. The UGA Georgia Radon Program identifies Gwinnett as one of four metro Atlanta counties with the highest radon risk, alongside Fulton, Cobb, and DeKalb.
Radon is the second leading cause of lung cancer in the United States and the leading cause among non-smokers. In Georgia, approximately 800 people die each year from radon-related lung cancer. Because radon is odorless, colorless, and tasteless, the only way to know your home's radon level is through testing.
Unlike DeKalb and Fulton counties where the average radon level often falls below the EPA threshold, Gwinnett County's Zone 1 classification means the predicted average itself exceeds the action level. This makes testing especially critical for every Peachtree Corners home, regardless of age or foundation type.
Gwinnett County Geology and Radon Risk
Peachtree Corners and Gwinnett County sit within the Piedmont physiographic province on extensive granite batholiths. The Stone Mountain pluton, a massive body of quartz monzonite granite that formed 300 to 350 million years ago during the Alleghenian Orogeny, extends underground up to 9 miles into Gwinnett County. Additional granitic formations including the Elberton and Ben Hill batholiths underlie the region. These granites contain uranium-bearing minerals, particularly zircon crystals, that produce radon gas as they decay.
Above the bedrock, a saprolite layer 15 to 30 feet thick, often called "rotten rock," serves as both a source and pathway for radon gas. This weathered zone is more porous than intact granite, allowing radon to migrate upward into the soil and ultimately into homes through foundation openings. Gwinnett County's extensive granite batholiths are a primary reason for its Zone 1 classification, distinguishing it from neighboring counties with more mixed geological profiles.
How Radon Mitigation Works in Peachtree Corners Homes

Radon Testing Across Peachtree Corners Communities
Peachtree Corners began development in the late 1960s as a planned community. Today the city includes established neighborhoods, newer developments, commercial districts, and the innovative Technology Park.
Established Subdivisions
Peachtree Station, with 717 homes dating to 1979, and Amberfield, with 450 homes on rolling hills, are among Peachtree Corners' largest residential communities. These neighborhoods feature a mix of split-level, ranch, and two-story homes with various foundation types including slabs, crawl spaces, and basements.
Homes built in the 1970s and 1980s on Gwinnett County's granite bedrock have had decades of settling, potentially creating additional pathways for radon entry through foundation cracks and gaps. Testing is the only way to know your home's actual radon levels.
Technology Park & Curiosity Lab
The 500-acre Technology Park is home to Curiosity Lab, a 25,000 square foot innovation center with a 3-mile autonomous vehicle roadway. Approximately 7,500 people work and over 1,000 live in the Technology Park area, all on the same Zone 1 granite bedrock.
Ground-floor offices, laboratories, and any below-grade spaces in Technology Park should be tested for radon. We provide commercial radon testing and mitigation services with compliance documentation for businesses and property managers.
The Forum & Mixed-Use
The Forum is Peachtree Corners' primary retail and dining district. Mixed-use developments combining residential and commercial space are increasingly common in the city. Ground-floor residential and commercial units in these developments face the same radon risk as traditional homes.
We test and mitigate condos, townhomes, and ground-floor commercial spaces throughout Peachtree Corners. HOAs and property management companies can contact us for building-wide testing programs.
Schools & Families
Peachtree Corners is primarily served by the Gwinnett County Public Schools Norcross cluster, including Norcross High School, Paul Duke STEM High School, Pinckneyville and Summerour Middle Schools, and elementary schools including Simpson and Peachtree Elementary. Wesleyan School, a private K-12 institution, is also located in Peachtree Corners.
Children are especially vulnerable to radon exposure. We provide radon testing and mitigation for schools, daycares, and childcare facilities throughout Peachtree Corners.
Radon Risk by Foundation Type in Gwinnett County
A peer-reviewed study of metro Atlanta homes found that foundation type is one of the strongest predictors of radon levels. Here's how common Peachtree Corners foundation types compare:
Most soil contact, below-grade living space. Common in homes built on Peachtree Corners' hillside lots. Research shows basements are the strongest predictor of elevated radon.
Direct contact with soil through the entire slab. Radon enters through cracks, construction joints, and gaps around plumbing. Common in newer Peachtree Corners homes.
Radon accumulates in the crawl space and enters living areas through gaps in the floor system. Sealing and sub-membrane depressurization are effective solutions.

Frequently Asked Questions About Radon in Peachtree Corners, GA
Common questions from Gwinnett County homeowners about radon testing and mitigation
Why is radon a concern in Peachtree Corners and Gwinnett County?
Peachtree Corners sits in Georgia's Piedmont region on granite bedrock that naturally contains uranium. Gwinnett County is classified as EPA Zone 1, the highest-risk category, with a predicted average indoor radon level exceeding 4.0 pCi/L. According to UGA Extension data, 22% to 28% of homes tested in Gwinnett County had radon levels above the EPA action level. Gwinnett is one of four metro Atlanta counties identified by the UGA Georgia Radon Program as highest risk.
What makes Gwinnett County Zone 1 for radon?
Gwinnett County's Zone 1 classification reflects the extensive granite batholiths beneath the county. The Stone Mountain pluton extends underground up to 9 miles into Gwinnett County, and additional granitic formations underlie much of the area. These granite formations contain uranium-bearing minerals that produce radon gas. The 15 to 30 foot saprolite layer of weathered rock above the bedrock serves as a major source and pathway for radon migration into homes.
How does a radon mitigation system work?
The most common radon mitigation method is sub-slab depressurization (SSD). A pipe is inserted through your foundation slab into the crushed rock or soil beneath. A specialized fan creates negative pressure below the foundation, drawing radon gas from beneath the home and venting it safely above the roofline before it can enter your living space. The system runs continuously and typically reduces indoor radon levels by 90% or more. Installation is usually completed in one day.
How much does radon mitigation cost in Peachtree Corners?
Radon mitigation systems in Peachtree Corners typically cost between $1,200 and $2,500 for standard residential installations. The final cost depends on your home's foundation type, size, and the complexity of the system required. Homes with basements or multiple foundation types may require additional suction points. We provide free estimates so you know the exact cost before any work begins.
Should I test for radon before buying a Peachtree Corners home?
Yes. With Gwinnett County classified as EPA Zone 1 and more than 1 in 5 homes testing above the EPA action level, radon testing is essential for any real estate transaction in Peachtree Corners. We provide 48-hour testing results to keep your deal on schedule. If elevated radon is found, mitigation typically costs $1,200-$2,500 and can be negotiated as a seller concession or repair before closing.
Does the Technology Park area need radon testing?
Yes. The 500-acre Technology Park in Peachtree Corners, home to Curiosity Lab and approximately 7,500 workers, is built on the same Zone 1 granite bedrock as the rest of the city. Ground-floor offices, labs, and any below-grade spaces should be tested. We provide commercial radon testing and mitigation with compliance documentation for Technology Park businesses and property managers.
How long does radon testing take in Peachtree Corners?
Short-term radon tests take 48 to 96 hours. We use professional continuous radon monitors that record hourly readings for the most accurate results. For real estate transactions, we offer 48-hour turnaround. Long-term tests (90+ days) provide a more accurate annual average and are recommended for homeowners not in a transaction.
Can radon levels change over time in my Peachtree Corners home?
Yes. Radon levels fluctuate seasonally, with winter typically producing higher readings due to closed windows and heating creating a stack effect that draws soil gas into the home. Foundation settling, renovations, and changes to HVAC systems can also affect radon entry. The EPA recommends retesting every two years, after major renovations, and whenever you move to a new home.
