Forsyth County is one of only four EPA Zone 1 counties in Georgia, the highest radon risk classification in the state. The underlying Powers Ferry metagraywacke bedrock produces elevated indoor radon in a documented 20 percent of tested Atlanta-area homes. The UGA Radon Program recorded a Forsyth County peak reading of 17.8 pCi/L during 2020 to 2025 testing. SafeAir provides independent, certified radon testing throughout Cumming with same-day scheduling and results in 48-72 hours.
Jeremy Shelton has been testing Cumming homes for indoor air quality problems since 2009. He founded SafeAir after discovering a mold infestation in his own crawlspace had affected his health for more than a year. Radon is different from mold in every way but one: you can’t know it’s there without a test.
SafeAir provides ACAC & IICRC-certified radon testing across Cumming with results in 48-72 hours. We test and report. We do not mitigate.

Yes, and Forsyth County is among the highest-risk radon counties in Georgia.
Forsyth County carries EPA Zone 1 designation, one of only four Zone 1 counties among Georgia’s 159. Zone 1 means the predicted average indoor radon screening level exceeds 4 pCi/L. The UGA Radon Education Program documented a Forsyth County peak reading of 17.8 pCi/L in testing conducted from 2020 to 2025, more than four times the EPA action level. Approximately 1 in 5 homes tested in the county exceeded the action level in that study.
The geological formation underlying Cumming is the Powers Ferry metagraywacke, a complex of biotite-quartz-plagioclase gneiss, mica schist, and amphibolite that covers all of Forsyth County. The 1995 AARST study “Radon and Geology in the Atlanta Area” found the more schistose zones of this formation produced elevated indoor radon in 20 percent of tested homes. Forsyth County borders Cherokee County, also EPA Zone 1, to the northwest. Cumming’s rolling terrain in established communities like Windermere drove basement construction as standard, the foundation configuration with the most direct radon entry pathway.
Zone data gives you a probability. A test gives you your actual number.
According to the U.S. EPA, radon is the second leading cause of lung cancer in the United States.
Cumming’s residential boom accelerated after GA-400 reached the city, producing thousands of homes on Forsyth County’s Zone 1 geology. Basements are common in the established master-planned communities, where rolling terrain drove below-grade construction. Newer active adult and townhome communities tend toward slab-on-grade.
Windermere (2000-2005) is one of the largest master-planned communities in Forsyth County, documented as having almost all homes with basements due to rolling terrain and luxury builder standards. Finished basements sit in direct soil contact with the Powers Ferry metagraywacke and schist, the configuration with the highest radon entry risk in Zone 1 geology.
Laurel Springs (Jack Nicklaus Signature golf, 750 custom homes, 1996-2006) and Polo Golf and Country Club (1976+) are luxury communities on rolling South Forsyth terrain where basement construction is standard. Finished basements are confirmed in Laurel Springs listings. Forsyth County recorded readings as high as 17.8 pCi/L in UGA testing from 2020 to 2025.
Vickery Village (2005+, EarthCraft-certified, mixed product of cottages and townhomes) and Traditions (active adult, Providence Group) use slab-on-grade construction. Slab homes in Zone 1 Forsyth County carry real radon risk through slab penetrations and control joints. The Powers Ferry schist geology generates radon regardless of whether the foundation is basement or slab.
The Crossing at Coal Mountain (northern Forsyth, active), Arden on Lanier (Pilgrim Mill Road), and hundreds of active new-home communities across Forsyth County are predominantly slab-on-grade. New construction in Zone 1 carries radon risk from the first day of occupancy. The underlying Powers Ferry metagraywacke is geological and predates any building permit.
Whatever your home type, the continuous monitor goes in your lowest livable level. The result is specific to your property, your foundation, your soil.
Jeremy or a SafeAir consultant places a calibrated continuous monitoring device in the lowest livable level of your home. The device records radon readings hour by hour over 48 hours.
Continuous electronic monitors produce significantly more data than charcoal canister kits. Their results are accepted by lenders, buyers’ agents, and real estate attorneys throughout Georgia. The $15 UGA Extension kit works for general awareness. It does not work for real estate transactions.
After device pickup, your written report arrives within 24 hours. It documents your radon level, testing conditions, and the inspector’s certification. A SafeAir consultant reviews the findings with you directly.
You do not need to be home during the 48-hour measurement period.

Radon comes up on most Cumming contracts now. Buyers’ agents request it. Some lenders require it. The due diligence window on most Georgia contracts runs 7–10 days.
What matters in that window: you need an independent result. A company that tests and sells mitigation has a financial reason to find a problem. SafeAir tests and reports only. If the result is below 4.0 pCi/L, you’re done. If it’s above, you know before closing and you negotiate from that position.
Mitigation in Cumming typically runs $800–$2,500 depending on foundation type and system design. Knowing the number before you close is leverage. Discovering it after is not.
If scheduling is time-sensitive, note your closing date in the form. SafeAir prioritizes contingency-window requests.
SafeAir does not sell radon mitigation systems. That is a deliberate choice.
Most radon companies test and mitigate. That creates a conflict: the company that finds a problem also profits from solving it. Jeremy built SafeAir to remove that conflict. He reports what the monitor records, regardless of the result. If your test comes back elevated, he explains what the number means and what your options look like. You choose your mitigator independently.
Jeremy holds certifications through ACAC (Certified Indoor Environmental Consultant, Certified Microbial Consultant) and IICRC. He has been testing indoor air quality in Georgia homes since 2009.
SafeAir tests homes and properties throughout Cumming and Forsyth County, from established communities along GA-400 to newer northern Forsyth subdivisions, including:
If your neighborhood isn’t listed, we still test there.
Forsyth County is one of only four EPA Zone 1 counties in Georgia, the highest risk classification in the state. Zone 1 means the predicted average indoor radon screening level exceeds 4 pCi/L. The UGA Radon Education Program recorded a Forsyth County peak of 17.8 pCi/L in testing from 2020 to 2025, and approximately 1 in 5 tested homes in the county exceeded the action level. The underlying geology is the Powers Ferry metagraywacke, whose more schistose zones produced elevated radon in 20 percent of tested Atlanta-area homes in the 1995 AARST study. Windermere's documented basement-heavy housing stock and the rolling terrain of South Forsyth communities represent the highest-risk configuration. Slab homes throughout the county carry radon entry risk through penetrations and joints from the same Zone 1 bedrock.
There are none. Radon is odorless, colorless, and produces no symptoms you would connect to it. Long-term exposure is cumulative. The only way to know if radon is present at an elevated level is a certified test.
Contact SafeAir for current pricing. For context: professional continuous monitor testing in the Cumming area typically runs $150-$300. The UGA Extension Program offers $15 charcoal kits for general screening, but those results are not accepted in most real estate transactions.
SafeAir uses 48-hour continuous electronic monitors. Your written report is typically delivered within 24 hours of device pickup. Most Cumming clients have results in hand within 3-4 days of scheduling.
The EPA recommends mitigation at that level. SafeAir provides the test and the result. We do not sell mitigation systems. If your result is elevated, we explain what it means and what your options are. Mitigation in Cumming typically costs $800-$2,500 depending on foundation type.
Georgia has no state law requiring radon disclosure or testing for home sales. However, buyers increasingly request it during due diligence, and some lenders require it on certain loan types. If a buyer requests a test and the contingency window is open, completing it before that window closes protects your transaction.
Jeremy has tested hundreds of Georgia homes since 2009.
