Radon in Alpharetta, Georgia: What North Fulton Homeowners Need to Know
Alpharetta is one of metro Atlanta's most affluent and fastest-growing cities, with a population exceeding 65,000. Located in North Fulton County, Alpharetta sits on extensive granite bedrock that characterizes the Piedmont geological region. This granite naturally contains uranium, which decays over time and releases radon gas that can seep into homes through foundations.
With an average indoor radon level of 4.9 pCi/L, Alpharetta exceeds the EPA's recommended action level of 4.0 pCi/L. The city is classified as EPA Zone 1—the highest radon risk category. According to state data, over 12,000 homes in the Alpharetta area have radon levels that warrant mitigation. This makes radon testing essential for all Alpharetta homeowners, regardless of home age or construction type.
Radon is the second leading cause of lung cancer in the United States, responsible for approximately 21,000 deaths annually. In Georgia alone, about 800 people die each year from radon-related lung cancer. Radon is particularly dangerous because it's invisible, odorless, and tasteless—the only way to know if your home has elevated levels is through professional testing.
Whether you live in a luxury estate in Windward, an executive home in Crabapple, a family home near Downtown Alpharetta, or a townhome in North Point, your property's radon levels depend on the specific soil and rock conditions beneath your foundation. Testing is the only way to find out.
North Fulton County Geology and Radon Risk
Alpharetta sits within the Piedmont physiographic province on extensive granite formations that extend 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 migrates through cracks and pore spaces in the soil and rock.
The same geological formation that makes North Fulton property values high—the granite bedrock that provides stable foundations—also creates conditions favorable for radon accumulation. Homes built on or near granite outcroppings, decomposed granite soils, or areas with fractured rock often have higher radon levels. The geology across Alpharetta, Milton, Johns Creek, and Roswell is essentially identical, explaining why the entire North Fulton corridor is classified as Zone 1.
Radon Testing Across Alpharetta Neighborhoods
Alpharetta features diverse housing from luxury estates to modern townhomes. Every property type on North Fulton's granite bedrock faces radon risk—new construction included.
Executive Homes & Estates
Alpharetta's luxury neighborhoods like Windward, Country Club of the South, and Crooked Creek feature large homes often with finished basements. Basements in contact with granite bedrock have the highest radon accumulation potential.
Larger homes require properly designed mitigation systems. Our engineers assess each property to ensure adequate coverage for the entire foundation footprint.
Master-Planned Communities
Communities like Haynes Bridge, Webb Bridge, and Providence feature newer construction on the same granite bedrock. Modern building codes don't require radon-resistant construction in Georgia, so even new homes need testing.
Tight building envelopes in modern homes can actually concentrate radon. If your builder didn't install a passive radon system, active mitigation may be needed.
Downtown & Historic Alpharetta
The downtown Alpharetta area and surrounding established neighborhoods include homes from various eras. Older foundations with more cracks and settling can allow easier radon entry.
We specialize in mitigation solutions that preserve the character of established homes while providing effective radon reduction. Systems can be routed discretely to minimize visual impact.
Schools, Daycares & Commercial
Fulton County Schools operates numerous schools in Alpharetta, and the city has many daycares and commercial buildings. Children are especially vulnerable to radon exposure due to higher respiration rates.
We provide commercial radon testing and mitigation services for Alpharetta businesses, schools, and multi-family properties with full compliance documentation.

Frequently Asked Questions About Radon in Alpharetta, GA
Common questions from North Fulton homeowners about radon testing and mitigation
Why is radon a major concern in Alpharetta?
Alpharetta sits on extensive granite bedrock in the North Fulton Piedmont region. This granite naturally contains uranium that decays into radon gas. With an average radon level of 4.9 pCi/L—above the EPA action level of 4.0 pCi/L—Alpharetta is classified as EPA Zone 1, meaning high radon potential. Nearly 1 in 5 homes tested in Fulton County exceed EPA guidelines.
What is the average radon level in Alpharetta, GA?
Alpharetta has an average indoor radon level of approximately 4.9 pCi/L, which is above the EPA's recommended action level of 4.0 pCi/L. The area is classified as EPA Zone 1, the highest risk category. Individual homes can test significantly higher depending on foundation type, soil conditions, and construction.
Should I test for radon in my new Alpharetta home?
Absolutely. New construction in Alpharetta faces the same radon risk as older homes because the underlying granite geology affects all properties regardless of age. Modern energy-efficient homes with tight building envelopes can actually trap radon more effectively. The EPA recommends testing all homes, including new construction, and retesting every two years.
How much does radon mitigation cost in Alpharetta?
Radon mitigation systems in Alpharetta typically cost between $1,200 and $2,500 for standard residential installations. Larger executive homes and estate properties may require more extensive systems. The final cost depends on your home's foundation type, size, and system complexity. We provide free estimates so you know the cost upfront.
What areas of Alpharetta have the highest radon levels?
Radon levels vary throughout Alpharetta based on localized geology and soil conditions. Areas in Windward, Crabapple, and the Milton border often test higher due to the granite formations. However, elevated radon has been found throughout Alpharetta—from downtown to Webb Bridge to North Point. Testing is the only way to know your specific home's radon level.
How long does radon testing take in Alpharetta?
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 Alpharetta, we offer 48-hour turnaround to keep deals on schedule.
What type of radon mitigation system works best for Alpharetta homes?
Sub-slab depressurization (SSD) is the most effective radon remediation method for Alpharetta homes. The system creates negative pressure beneath your foundation to intercept radon before it enters your living space. For homes with crawl spaces, sub-membrane depressurization is used. Both approaches can reduce radon levels by 99% or more.
Do I need radon testing before selling my Alpharetta home?
While Georgia does not legally require radon testing for home sales, most buyers in North Fulton County request it during inspections. Given Alpharetta's Zone 1 classification and elevated radon levels, providing a recent test or having a mitigation system installed can strengthen your listing and prevent delays at closing.
