ACAC COUNCIL-CERTIFIED · IICRC CERTIFIED · INDEPENDENT RADON TESTING SINCE 2009
★ 5.0 · 156 REVIEWSMON–FRI 8AM–5PM
Dunwoody’s established neighborhoods feature ranch and two-story homes from the 1970s-1990s. Many have finished basements where radon concentrations tend to be highest. SafeAir provides independent, certified radon testing in Dunwoody with same-day scheduling, results in 48-72 hours, and no mitigation conflict of interest.
Jeremy Shelton has been testing Dunwoody 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 Dunwoody with results in 48-72 hours. We test and report. We do not mitigate.

Yes, and DeKalb County’s test data tells a specific story.
Dunwoody and DeKalb County are classified as EPA Zone 2, where average indoor radon levels are predicted between 2 and 4 pCi/L. The EPA action level is 4.0 pCi/L. In DeKalb County, approximately 18.9 percent of tested homes exceed that threshold, one of the higher rates in the Atlanta metro.
Dunwoody sits on Piedmont Plateau bedrock: biotite gneiss, granite, and mica schist with a saprolite weathering layer 10-25 feet thick. These uranium-bearing rocks decay to produce radon, and the porous saprolite layer is a direct migration path into home foundations. Dunwoody’s sloped terrain means basements and split-level lower levels are common, and those spaces consistently produce the highest radon concentrations in a given home.
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.
Dunwoody’s housing stock was built primarily in the 1970s and 1980s, well before radon testing was a standard part of home construction or sale.
Holly Oak, Hidden Branches, and Withmere include ranch-style homes from the 1960s-1970s, built before radon testing was standard practice. Ranch homes on crawlspace foundations give soil gases a short path to the living level. Dunwoody’s Piedmont geology makes that path active for many properties.
Newer townhome communities and condo towers along Perimeter Center Parkway use slab-on-grade construction. Radon enters through slab joints and plumbing penetrations. DeKalb County’s 18.9 percent above-threshold rate reflects risk that applies to slab homes as well as older housing stock.
Georgetown and Vermack are active teardown markets where 1960s ranches are replaced by tightly sealed new construction. Modern homes concentrate radon from the same Piedmont soil as the originals. A new structure doesn’t change the underlying source.
Dunwoody’s hilly terrain produced an inventory of split-level and colonial homes in Dunwoody Club Forest and Georgetown with partial or full basements. A peer-reviewed study on DeKalb County homes identified having a basement as the single strongest predictor of elevated radon. These homes are the first priority for testing.
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 Dunwoody 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 Dunwoody 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 Dunwoody and DeKalb County, including:
If your neighborhood isn’t listed, we still test there.
Dunwoody and DeKalb County are classified as EPA Zone 2, with average predicted indoor radon levels between 2 and 4 pCi/L. Within that range, approximately 18.9 percent of DeKalb County homes tested exceed the 4.0 pCi/L action level, one of the higher rates in the Atlanta metro. Dunwoody's prevalence of 1970s-1980s split-level and colonial homes with basements on sloped Piedmont terrain is a contributing factor. A certified test is the only accurate measurement for your specific property.
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 Dunwoody 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 Dunwoody 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 Dunwoody 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.
