ACAC COUNCIL-CERTIFIED · IICRC CERTIFIED · INDEPENDENT RADON TESTING SINCE 2009

College Park’s Historic District includes 853 structures on the National Register of Historic Places. Most were built between the 1890s and 1930s on pier-and-beam and crawlspace foundations, before radon testing existed. SafeAir provides certified, independent radon testing in College Park with results in 48-72 hours.
Jeremy Shelton has been testing College Park 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 College Park with results in 48-72 hours. We test and report. We do not mitigate.

Yes, and College Park’s historic housing stock is the primary factor.
College Park straddles two counties with different EPA radon designations. The majority of the city’s residential neighborhoods fall within Fulton County, designated Zone 2, with predicted average indoor levels between 2 and 4 pCi/L. A smaller portion falls within Clayton County, designated Zone 3, where roughly one in ten homes tested still exceeds the EPA action level of 4.0 pCi/L. Zone designations reflect county-wide averages and do not predict any individual home’s radon level.
College Park sits in the outer Georgia Piedmont, where metamorphic crystalline bedrock underlies a saprolite layer above red clay soils. The more significant factor here is foundation type. The Historic College Park district’s 1890s to 1930s pier-and-beam and crawlspace homes allow radon from the saprolite to enter the living space regardless of where the property falls on a county radon map.
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.
College Park’s housing ranges from 1890s Queen Anne Victorians in the National Register Historic District to post-1980 ranch homes along the Camp Creek Parkway corridor. Foundation type is the clearest predictor of radon accumulation across this range.
College Park’s National Register Historic District contains 853 structures built primarily on pier-and-beam and masonry perimeter crawlspace foundations, standard for early 20th century Southern construction. College Park is Georgia’s fourth-largest urban historic district, representing a concentrated inventory of pre-radon-testing-era crawlspace homes that sit above the radon-generating saprolite layer with minimal barrier in unmodified examples.
Residential areas surrounding Historic College Park include post-1960 ranch homes on concrete slab foundations, the dominant construction type for this era in the Atlanta metro. Slab homes present lower average radon entry rates than open crawlspaces, but foundation cracks, utility penetrations, and slab-wall joints remain pathways for soil gas.
Renovation activity in Historic College Park has produced tightly insulated versions of 1900s to 1930s structures with updated mechanical systems and improved vapor barriers. When an older crawlspace home is renovated without addressing radon entry pathways at the foundation, radon concentrations in the living space can increase. Testing after major renovations provides a current baseline for the improved home.
The Camp Creek Parkway corridor includes newer residential development from the 1980s through the 2000s, primarily slab-on-grade construction. This area straddles the Fulton and Clayton county line. Zone designations are county averages and do not predict individual home results. Testing confirms the actual radon level regardless of construction era or county designation.
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.
Calibrated continuous monitor set in your lowest livable level.
Hour-by-hour readings recorded. No need to be home.
Certified written report, reviewed with you directly.
Radon comes up on most College Park 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 College Park 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 College Park and the surrounding South Fulton and Clayton County area, including:
If your neighborhood isn’t listed, we still test there.
College Park straddles Fulton County (EPA Zone 2) and Clayton County (EPA Zone 3). The majority of residential neighborhoods are in the Fulton County portion. Zone 3 carries a lower predicted county average, but approximately one in ten Clayton County homes tests above the EPA action level of 4.0 pCi/L. The most significant radon factor in College Park is foundation type: the Historic College Park district's 1890s to 1930s pier-and-beam and crawlspace homes are the configuration most likely to accumulate radon, regardless of which county a given property falls in.
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 College Park 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 College Park 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 College Park 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.
