ACAC COUNCIL-CERTIFIED · IICRC CERTIFIED · INDEPENDENT RADON TESTING SINCE 2009
★ 5.0 · 156 REVIEWSMON–FRI 8AM–5PM
Gainesville sits at the Blue Ridge foothills in Hall County, one of Georgia’s EPA Zone 1 counties, where the Inner Piedmont’s granite-gneiss bedrock and the Brevard Fault Zone generate consistently elevated radon levels. From mid-century ranches in Longstreet Hills to newer lakefront communities on Lake Lanier, a certified test is the only way to know your number.
Jeremy Shelton has been testing Gainesville 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 Gainesville with results in 48-72 hours. We test and report. We do not mitigate.

Yes, and Hall County’s geology is a key factor.
Gainesville and Hall 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 Brevard Fault Zone passes directly through Gainesville, creating extensive rock fracturing that accelerates radon migration from the Inner Piedmont’s uranium-bearing gneiss and granite. Testing data for the Gainesville area reports an average near 4.75 pCi/L, above the EPA action threshold.
Gainesville’s housing stock spans more than a century: Victorian and Neoclassical homes in the Green Street Historic District, 1920s mill-worker cottages in Chicopee Village, mid-century ranches in Longstreet Hills and Indian Hills, and master-planned communities along the Lake Lanier corridor. Each construction era and foundation type carries a different radon entry profile. Two homes on the same street can test at completely different levels.
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.
Gainesville’s range of housing, from 1920s mill cottages to energy-efficient Lake Lanier builds, is what makes ZIP-code generalizations unreliable here.
Gainesville’s established neighborhoods from the 1940s through the 1980s were built on raised crawlspace foundations, the standard approach for sloped Inner Piedmont terrain. These crawlspaces sit over uranium-rich granite-gneiss soil, and without encapsulation, radon migrates through floor assemblies into living areas above.
Newer slab-on-grade homes in Gainesville’s master-planned communities sit on concrete poured over the same Inner Piedmont soils that generate radon throughout Hall County. Utility penetrations and slab joints allow radon to enter even well-built newer homes, and in a Zone 1 county, the percentage of slab homes testing elevated is significant.
High-end lakefront custom homes are built to modern energy codes with sealed vapor barriers and foam insulation that minimize air exchange. While this reduces heating and cooling costs, it also reduces the air infiltration that would otherwise dilute radon. A tightly sealed home on Zone 1 geology can test higher than a drafty older ranch on the same soil.
The Victorian homes along Green Street and the 1920s mill-worker cottages of Chicopee Village were built decades before radon was identified as a health concern, with open, unencapsulated crawlspaces and no vapor barriers. These homes sit on Hall County’s longest-undisturbed soils and have almost never been tested.
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.

Hour-by-hour readings recorded. No need to be home.

Radon comes up on most Gainesville 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 Gainesville 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 Gainesville and Hall County, including Lake Lanier corridor communities:
If your neighborhood isn’t listed, we still test there.
Gainesville and Hall County are classified as EPA Zone 1, the highest-risk radon zone in Georgia, where the Inner Piedmont's granite-gneiss bedrock and the Brevard Fault Zone create elevated radon potential across the housing stock. Testing data for the Gainesville area reports an average near 4.75 pCi/L, above the EPA action threshold of 4.0 pCi/L. In Zone 1 counties, roughly 40 to 60 percent of tested homes register at or above the EPA action level. A calibrated, certified test is the only accurate measure of any 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 Gainesville 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 Gainesville 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 Gainesville 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.
