Johns Creek is one of metro Atlanta’s most active real estate markets. Radon testing comes up on nearly every transaction. SafeAir provides the independent, certified result buyers and sellers need: no mitigation tied to the test, just a credible report in 48-72 hours.
Jeremy Shelton has been testing Johns Creek 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 Johns Creek with results in 48-72 hours. We test and report. We do not mitigate.
Know your number

Yes, and the housing stock here makes testing especially relevant.
Johns Creek and Fulton County are classified as EPA Zone 2, where average indoor radon levels are predicted between 2 and 4 pCi/L. The EPA action level is 4.0 pCi/L. North Fulton County, including Johns Creek, consistently produces higher readings than the south county average. The granite-rich Piedmont geology underlying the area is the primary driver.
Johns Creek’s hilly terrain, developed primarily from the 1980s through the 2000s, produced a housing stock with a high prevalence of walkout and daylight basements. Executive and custom homes in golf course communities like Country Club of the South, St. Ives, and Rivermont sit on sloped lots where basement construction was standard. Basements accumulate radon at higher concentrations than any other part of the home.
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.
Johns Creek’s executive home market and hilly terrain produce a housing stock where basement construction is the norm and radon testing is a standard buyer request.
Rivermont, one of the oldest communities in the Johns Creek area, includes homes built from the 1970s through the 1980s. Original construction along the Chattahoochee River corridor includes crawlspace homes on flatter riparian lots. These homes predate standard radon testing practice and most haven’t been screened by current owners.
Some flatter parcels in Medlock Bridge, Oxford Mill, and similar communities use slab-on-grade construction. Radon enters through slab joints and plumbing penetrations. North Fulton County’s granite and saprolite geology means slab homes here test elevated more often than owners typically expect.
Bellmoore Park and similar gated communities built from 2015 onward feature tightly sealed, energy-efficient construction. Reduced air exchange concentrates radon entering from the underlying granite geology. New construction is not a reliable proxy for low radon levels.
Country Club of the South, St. Ives Country Club, Harrington Falls, and Nesbit Lakes sit on hilly terrain where walkout and daylight basements are standard. These finished basement spaces are where radon accumulates first and reaches the highest concentrations in a home. Many serve as primary family living areas, making Johns Creek’s basement inventory the top testing priority.
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 Johns Creek 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 Johns Creek 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 Johns Creek and North Fulton County, including:
If your neighborhood isn’t listed, we still test there.
Johns Creek and Fulton County are classified as EPA Zone 2, where average indoor radon levels are predicted between 2 and 4 pCi/L. North Fulton County consistently produces higher readings than the south county average, driven by the granite-rich Piedmont geology underlying the area. Johns Creek's inventory of 1990s-2010s executive homes with walkout and daylight basements on sloped terrain represents the configuration where radon concentrations are consistently highest. A certified test in your lowest livable level is the only reliable measure of your home's specific 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 Johns Creek 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 Johns Creek 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 Johns Creek 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.
