★ 5.0 · 156 REVIEWSMON–FRI 8AM–5PM
Suwanee’s residential communities straddle Gwinnett and Forsyth counties, with neighborhoods like Laurel Springs and Grand Cascades physically in Forsyth County despite a Suwanee mailing address. Forsyth County is EPA Zone 1, and the city’s measured radon average of approximately 4.6 pCi/L is the highest of any city in Gwinnett County. SafeAir provides independent, certified radon testing throughout Suwanee with same-day scheduling and lab-grade results in 48-72 hours.
Jeremy Shelton has been testing Suwanee 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 Suwanee with results in 48-72 hours. We test and report. We do not mitigate.

Yes, and Suwanee’s dual-county geography makes testing especially relevant.
Gwinnett County is EPA Zone 2, but the measured radon average for Suwanee is approximately 4.6 pCi/L, the highest of any city in Gwinnett County and above the EPA action level of 4.0 pCi/L. Suwanee’s northwestern communities, including Laurel Springs and Grand Cascades, are physically in Forsyth County, which is EPA Zone 1 territory where readings as high as 17.8 pCi/L have been documented by the UGA Radon Education Program. The Brevard Fault Zone, a 600-kilometer Appalachian tectonic feature, fractures the granite-gneiss and schist bedrock beneath this corridor and creates direct migration pathways for radon from bedrock to building foundations.
The UGA Radon Education Program estimates that 22 to 28 percent of tested Gwinnett County homes have elevated radon levels. A 15 to 30-foot saprolite layer of decomposed granite beneath the red clay surface soils acts as a radon reservoir, providing a permeable medium from bedrock to foundation. Suwanee’s sloped Chattahoochee River corridor drove basement and daylight-basement construction in communities like Rivermoore Park and The River Club, where foundation walls are in direct soil contact with Piedmont saprolite and bedrock on the uphill side. The only way to know your home’s actual radon level is a certified test.
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.
Suwanee’s residential communities span four decades of construction, from 1983 ranch homes in Maple Ridge and Settles Bridge to luxury Chattahoochee riverfront estates in Rivermoore Park and The River Club. Foundation type and lot topography both affect radon entry, and Suwanee’s sloped terrain along the river corridor produced an unusual concentration of walkout basement homes.
Maple Ridge (1983-1987), Settles Bridge (1988), Berkshire (1991), and Aberdeen (1993) represent Suwanee’s earliest suburban expansion. Crawlspace foundations were the standard in Gwinnett County during this era. These properties are now 30 to 40 years old with aging vapor barriers and foundation seals. Radon migrates through crawlspace soil directly beneath living space floor decking.
Rivermoore Park (2001+) and The River Club (2003-2017) sit on sloped terrain along the Chattahoochee River. Many homes in both communities feature walkout and finished basements confirmed in real estate listings. Finished basements are the foundation configuration with the most direct radon entry pathway: basement walls and floors sit in direct soil contact with Piedmont saprolite and bedrock on the uphill side.
Laurel Springs (Jack Nicklaus golf community, 1996-2006) and Grand Cascades (1995-2007) are physically in Forsyth County, which carries EPA Zone 1 designation. Finished basements are confirmed in Laurel Springs listings. The Forsyth County portion of Suwanee recorded peak readings as high as 17.8 pCi/L in UGA Radon Program data from 2020 to 2025.
Edinburgh (2002) and Turnberry (2012) used slab-on-grade construction with hard-coat stucco and stone exteriors. Slab homes in Suwanee are not radon-exempt: radon enters through control joints, utility penetrations, and slab cracks from the same Piedmont metamorphic bedrock that underlies every foundation type in the city.
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 Suwanee 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 Suwanee 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.

If your neighborhood isn’t listed, we still test there.
Suwanee spans both Gwinnett County (EPA Zone 2) and Forsyth County (EPA Zone 1), making zone-based risk estimates less reliable here than in other cities. The Gwinnett-side measured average for Suwanee is approximately 4.6 pCi/L, the highest city-level average in Gwinnett County and above the EPA action level of 4.0 pCi/L. Forsyth County, which covers Suwanee's northwestern communities including Laurel Springs and Grand Cascades, recorded a peak reading of 17.8 pCi/L in UGA Radon Program testing from 2020 to 2025. The Brevard Fault Zone fractures the crystalline bedrock through this corridor, accelerating radon migration from granite-gneiss to building foundations. Individual home testing is the only reliable measure. Zone and county designations are broad predictions, not your home's number.
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 Suwanee 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 Suwanee 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 Suwanee 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.
