ACAC COUNCIL-CERTIFIED · IICRC CERTIFIED · INDEPENDENT RADON TESTING SINCE 2009
★ 5.0 · 156 REVIEWSMON–FRI 8AM–5PM
Union City’s residential areas mix established South Fulton neighborhoods with newer subdivisions. Both housing types can harbor elevated radon levels with no visible signs. SafeAir provides independent radon testing in Union City with lab-certified results in 48 to 72 hours.
Jeremy Shelton has been testing Union City 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 Union City with results in 48-72 hours. We test and report. We do not mitigate.

Yes, and Union City’s South Fulton geology is worth knowing.
Union City and Fulton County are classified as EPA Zone 2, where roughly 25 to 40 percent of tested homes exceed the EPA action level of 4.0 pCi/L. The Southern Piedmont metamorphic and granitic rock that underlies South Fulton contains uranium that decays to radon. A thick saprolite layer, Georgia’s characteristic decomposed red clay, sits between bedrock and building foundations and allows radon to migrate upward efficiently.
Union City’s housing stock spans from vintage ranches built in the 1970s on crawlspace foundations to the wave of slab-on-grade suburban homes built during the 2000s growth decade, when the city population roughly doubled. Homes built on slab are not exempt: HVAC systems create negative pressure that draws soil gas through slab penetrations and expansion joints. Two homes on the same street in Oakley Township or Barrington can test differently.
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.
Union City’s housing stock breaks cleanly into two eras, each with a distinct radon entry profile.
The oldest residential communities in Union City, including Dixie Lakes and Shannon Villas, feature ranch and cottage homes built through the 1970s and 1980s on crawlspace and pier-and-beam foundations. Open crawlspaces without vapor barriers are a direct radon pathway from soil to living space.
Roughly 40 percent of Union City homes were built in the 2000s, during the city’s peak growth period. Barrington, Oakley Township, Brookstone, and Brentwood Place represent this era: slab construction on red-clay soil where pipe penetrations and expansion joints are the primary radon entry points.
Heritage Walk and Mallory Park represent a significant attached and townhome inventory built 2005 to 2020. Ground-floor units in townhome communities share the same slab-to-soil interface as detached homes and should be tested independently.
Christian Corners and newer phases along Flat Shoals Road represent Union City’s most recent development wave. Georgia does not require radon-resistant new construction, so slab penetrations remain potential entry points in homes built after 2015.
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 Union City 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 Union City 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 Union City and South Fulton County, including:
If your neighborhood isn’t listed, we still test there.
Union City and Fulton County are classified as EPA Zone 2, where a significant percentage of tested homes exceed the EPA action level of 4.0 pCi/L. South Fulton County sits in Georgia's Piedmont geologic province, where metamorphic and granitic bedrock releases radon into the thick saprolite layer above it. The dominant slab-on-grade housing stock built during the 2000s growth decade is not immune: negative pressure from HVAC systems draws soil gas through slab cracks and pipe penetrations. A certified test gives you your specific home's number, independent of zone averages.
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 Union City 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 Union City 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 Union City 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.
