Stone Mountain sits directly above the Stone Mountain granite pluton, a 9-mile-wide exposed formation that produced the highest measured radon rate of any geological unit in the 1995 AARST Atlanta-area radon study: 37.9 percent of tested homes exceeded the EPA action level of 4.0 pCi/L. The visible granite at Stone Mountain Park is the same uranium-bearing formation beneath every residential neighborhood in the city. SafeAir provides independent, certified radon testing throughout Stone Mountain with same-day scheduling and results in 48-72 hours.
Jeremy Shelton has been testing Stone Mountain 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 Stone Mountain with results in 48-72 hours. We test and report. We do not mitigate.

Yes, and Stone Mountain sits on the geological formation with the highest documented radon rate in the Atlanta metro.
Stone Mountain and DeKalb County fall in EPA Zone 2. Within that zone, the Stone Mountain granite pluton produced a 37.9 percent elevated-home rate in the 1995 AARST Atlanta-area study, the highest of any formation surveyed. That rate is more than double the county-wide elevated-home figure for DeKalb of approximately 18.9 percent. The pluton extends roughly 9 miles and underlies Stone Mountain Village, Smoke Rise, Hidden Hills, and portions of Tucker and Snellville.
The exposed granite at Stone Mountain Park represents the same uranium-bearing formation beneath every residential foundation in the city. Stone Mountain Village homes from the 1870s through 1930s sit on pier-and-beam foundations directly above weathered granite surface. Smoke Rise estates and Hidden Hills subdivisions added crawlspace and slab homes in the 1960s through 1990s on the same pluton, extending the high-radon zone across three construction generations.
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.
Every residential foundation in Stone Mountain sits above the same granite pluton, but foundation type determines how much radon enters and accumulates.
The Village district contains the oldest housing stock in the city, with pier-and-beam and crawlspace foundations from the late 19th and early 20th centuries. These structures sit closest to the weathered granite surface and have no vapor barriers or sub-slab features.
Smoke Rise was developed in the 1960s and 1970s as a large-lot estate community at the northeast edge of the pluton. Homes here include crawlspace and basement configurations on direct granite-gneiss contact. Basement homes accumulate radon first at the lowest livable level before it rises to upper floors.
Hidden Hills spans three decades of construction with a mix of crawlspace and slab-on-grade foundations. The community sits within the documented high-radon zone around the Stone Mountain pluton. Testing is the only way to confirm a specific property’s level within this range.
Newer construction near Stone Mountain Park and the GA-78 commercial corridor uses energy-efficient building standards on the same uranium-bearing granite. Tighter sealing concentrates radon more effectively than older homes with natural air infiltration.
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.

Radon comes up on most Stone Mountain 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 Stone Mountain 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 Stone Mountain and the surrounding DeKalb County area, including:
If your neighborhood isn’t listed, we still test there.
Stone Mountain and DeKalb County are classified as EPA Zone 2. Within that zone, the Stone Mountain granite pluton produced a 37.9 percent elevated-home rate in the 1995 AARST Atlanta-area radon study, the highest of any geological formation surveyed. That rate is more than double the DeKalb County-wide elevated-home figure of approximately 18.9 percent. The pluton extends roughly 9 miles and underlies Stone Mountain Village, Smoke Rise, Hidden Hills, and portions of Tucker and Snellville. The visible granite at Stone Mountain Park is the same uranium-bearing formation beneath every residential foundation in the city.
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 Stone Mountain 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 Stone Mountain 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 Stone Mountain 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.
