Huntsville is in Madison County, an EPA Radon Zone 1 county — the highest-risk category — and one of the counties the Alabama Department of Public Health lists as having the highest potential for elevated radon.
BamaClean Environmental provides NRSB-certified radon measurement using professional continuous radon monitors and EPA / ANSI-AARST protocols. We test only — we don’t sell mitigation — so your results stay impartial.
$300 for a ground floor up to 2,000 sq ft · $400 for 2,001–4,000 sq ft
Madison County Extension data has shown some Huntsville-area zip codes — including parts of downtown Huntsville — with 30% or more of tested homes above the EPA action level. Local officials have pointed to the limestone bedrock under the Tennessee Valley as a factor.
From older homes near downtown to newer construction on the south side, radon can show up in any home, and levels vary from house to house. The only way to know is to test.
We test homes throughout Huntsville, including Research Park, Five Points, Jones Valley, and Monte Sano, plus Meridianville, Hazel Green, Owens Cross Roads, and Gurley.
Huntsville homes range from older houses with crawlspaces and basements to newer slab construction. Radon can enter through cracks in the slab, gaps around pipes, sump pits, and crawlspaces, so the foundation type shapes where and how we place the monitor.
The EPA recommends fixing a home at or above 4 pCi/L and considering it between 2 and 4 pCi/L.

A charcoal kit averages whatever it absorbed. It can’t show when levels spiked, it doesn’t know if a window was open or the kit was moved, and its accuracy depends on where you set it. It’s a rough screen, not a result you can act on or hand to a buyer.
A Certified Test Gives You Data
We use a professional continuous radon monitor that logs readings every hour and flags interference. It’s placed and documented to ANSI-AARST protocol by an NRSB-certified specialist, so your Huntsville result holds up for your family’s decisions and for a real estate transaction.

FAQ
Radon Testing in Huntsville: FAQs
Is radon common in Huntsville?
Yes. Madison County is an EPA Radon Zone 1 county, and Madison County Extension data has shown some Huntsville-area zip codes with 30% or more of tested homes above the EPA action level of 4 pCi/L.
Do homes on Monte Sano or near downtown have more radon?
Radon depends on each home’s soil, foundation, and construction, so levels vary house to house. That’s why every home should be tested individually.
Do you test for home sales in Huntsville?
Yes. We follow EPA and ANSI-AARST protocols and provide real-estate-ready documentation. Tell us your closing deadline when you book.
How does radon get into a home?
Radon is a gas that forms in soil and rock. It moves up through slab cracks, gaps around pipes and wiring, sump pits, and crawlspaces, and it can build up inside, especially on the lowest levels.
Can you test after a mitigation system is installed?
Yes. We offer post-mitigation verification testing. Because we don’t install systems, our follow-up test is an independent check that the system brought your level down.
How much does radon testing cost?
$300 for a ground floor up to 2,000 sq ft and $400 for 2,001 to 4,000 sq ft. Upper floors don’t change the price. Larger homes, call for a quote.
How long does a radon test take?
A minimum of 48 hours under closed-building conditions, using a professional continuous radon monitor. You get a written report with your pCi/L result.
Do you sell radon mitigation?
No. We test only, so our results stay impartial. If your level is high, we explain your results and next steps.
