Snellville’s housing stock is concentrated in the 1980s and early 1990s, with 91 percent single-family homes and a median construction year of 1989. The underlying bedrock is the Snellville Formation, a named USGS geological unit distinct from other Gwinnett County formations. Gwinnett County testing data shows a Snellville city average near 4.2 pCi/L, above the EPA action level of 4.0 pCi/L. SafeAir provides independent, certified radon testing throughout Snellville with same-day scheduling and results in 48-72 hours.
Jeremy Shelton has been testing Snellville 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 Snellville with results in 48-72 hours. We test and report. We do not mitigate.

Yes, and Snellville sits on the Snellville Formation, a named USGS geological unit with measurable uranium concentrations.
Gwinnett County is EPA Zone 2, and city-level data for Snellville shows an average near 4.2 pCi/L, above the EPA action level of 4.0 pCi/L. The Snellville Formation is a distinct USGS-mapped geological unit, not simply a county zone designation: granite-gneiss with measurable uranium concentrations generates the radon that migrates through soil to foundations throughout the city.
Snellville’s median construction year of 1989 means roughly half the housing stock was built before 1990. That pre-1990 half is dominated by crawlspace construction: Summit Chase (1973), Bridgewater (1986), and Lochwolde (1988) are the defining community examples. Post-1990 construction shifted to slab-on-grade. Both foundation types test elevated in the Snellville Formation zone, and the Gwinnett County elevated-home rate of 22 to 28 percent across the county reflects that.
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.
Snellville’s 1980s peak and the pre-1990 crawlspace dominance of its defining communities make the city one of the more relevant Gwinnett testing areas.
Summit Chase, developed from 1973, is one of Snellville’s original communities and reflects the crawlspace-on-granite-gneiss pattern of Gwinnett’s early suburban development. Homes here sit on the Snellville Formation with open or minimally sealed crawlspaces from before modern vapor barrier standards.
Bridgewater (1986) and Lochwolde (1988) were developed just before the late-1980s shift toward slab construction. Both communities use crawlspace foundations built before modern radon-resistant practices. Pre-vapor-barrier construction means soil gas enters more directly than in newer homes on the same bedrock.
Post-1990 Snellville subdivisions including Brookwood Hills, Norris Lake Estates, and Centerville-area developments shifted to slab-on-grade as the standard. Radon enters through concrete joints and utility penetrations in the same Snellville Formation geology.
Newer communities including Lenora Park and Westbrook at Arbor Hill use modern energy-efficient construction. Tighter sealing concentrates whatever radon enters through slab penetrations from the underlying Snellville Formation. Testing confirms actual levels regardless of how new the home is.
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 Snellville 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 Snellville 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 Snellville and the surrounding Gwinnett County area, including:
If your neighborhood isn’t listed, we still test there.
Snellville and Gwinnett County are classified as EPA Zone 2, with a Snellville city average near 4.2 pCi/L, above the EPA action level of 4.0 pCi/L. The Snellville Formation, a named USGS geological unit, underlies the city and is characterized by granite-gneiss with measurable uranium concentrations. Summit Chase (1973), Bridgewater (1986), and Lochwolde (1988) represent the crawlspace-dominant pre-1990 era that accounts for roughly half of Snellville's housing stock. The Gwinnett County Extension Office cites an elevated-home rate of 22 to 28 percent across the county.
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 Snellville 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 Snellville 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 Snellville 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.
