ACAC COUNCIL-CERTIFIED · IICRC CERTIFIED · INDEPENDENT RADON TESTING SINCE 2009
★ 5.0 · 156 REVIEWSMON–FRI 8AM–5PM
Austell’s west Cobb location puts it at the edge of Cobb and Douglas counties, where older residential construction meets growing suburban development and radon testing is worth doing regardless of home age. SafeAir provides independent, certified radon testing in Austell with results in 48 to 72 hours.
Jeremy Shelton has been testing Austell 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 Austell with results in 48-72 hours. We test and report. We do not mitigate.

Yes, and Austell sits on some of the most studied radon-producing geology in the county.
Austell and Cobb County sit in EPA Zone 1, the highest risk designation, where average indoor radon screening levels are predicted to exceed 4.0 pCi/L. The bedrock formation beneath Austell is literally named after the city: the Austell Gneiss, a 400-million-year-old metamorphic rock. USGS field measurements near the Lithia Springs Quarry found radioactivity running two to three times background levels, with uranium concentrations as high as 240 parts per million near pegmatitic dikes within the formation.
Austell’s housing stock ranges from the 1930s Clark Thread Mill worker cottages on crawlspace foundations to 1960s and 1970s four-sided brick ranches, 1990s suburban developments, and current new construction along the Sweetwater Creek corridor. The uranium-enriched saprolite layer sits below all of it. Radon migrates upward through crawlspace openings, slab cracks, and foundation penetrations regardless of when the home was built.
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.
Austell’s housing spans nine decades of construction. The Austell Gneiss formation runs beneath all of it.
The Clark Thread Mill Historic District contains approximately 100 brick and frame worker cottages built 1931 to 1936 on crawlspace and pier-and-beam foundations. Original downtown Austell stock along Thompson Street follows the same era and foundation type. These homes sit directly above the Austell Gneiss, one of the most radioactively documented rock formations in western Cobb County.
Apple Valley and Cameron Woods represent Austell’s largest housing cohort: all-brick ranch homes built 1960 to 1985 on crawlspace foundations. This is the classic West Cobb residential form. In Zone 1 Cobb County, crawlspace-era brick ranches consistently represent the highest-risk configuration for radon accumulation.
Anderson Ridge, Ambercrest, and Silver Creek Hills brought two-story traditional homes to Austell in the 1990s and early 2000s. This era transitions from crawlspace to slab-on-grade on flatter lots. Cobb County’s Zone 1 designation applies equally across both foundation types.
Sweetwater Manor, Creekside at Wade Farm, and Flint Hill Park represent Austell’s post-2007 new construction wave. Slab-on-grade is standard. Georgia does not mandate radon-resistant construction, and the Austell Gneiss’s documented uranium content means soil gas concentrations can push readings above 4.0 pCi/L even through hairline slab cracks.
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.
Calibrated continuous monitor set in your lowest livable level.
Hour-by-hour readings recorded. No need to be home.
Certified written report, reviewed with you directly.
Radon comes up on most Austell 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 Austell 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 Austell and West Cobb County, including:
If your neighborhood isn’t listed, we still test there.
Austell and Cobb County are classified as EPA Zone 1, the highest risk designation, where average indoor radon screening levels are predicted to exceed 4.0 pCi/L. The Austell Gneiss, a 400-million-year-old metamorphic formation named for the city, has been documented by USGS with uranium concentrations up to 240 parts per million in local dike exposures. This uranium-enriched bedrock generates radon that migrates through the thick saprolite layer into Austell's homes. A certified test is the only way to determine your specific home's radon level.
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 Austell 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 Austell 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 Austell 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.
No obligation. No upsell. Just a certified result you can trust.
