Radon mitigation in Huntsville, Alabama
Radon is a colorless, odorless gas that seeps up from the soil into your home. It is the second leading cause of lung cancer in the U.S., and the only way to know your level is to test. If your home tests high, a radon mitigation system pulls the gas from under your foundation and vents it above your roof. Tell us about your home and we will connect you with a local mitigation contractor.
What your test result means (pCi/L)
Why Huntsville homes get tested
North Alabama sits on limestone-rich ground with cracks and cave systems that let soil gas move freely. Madison County falls in EPA Radon Zone 1, the highest-potential category. Two houses on the same street can test very differently, so a neighbor’s result tells you little about yours.
Radon enters through cracks in slabs and foundation walls, sump pits, floor drains, gaps around pipes, and exposed soil in crawlspaces. Homes with basements or crawlspaces are common around Huntsville, Madison and Hazel Green, and each foundation type needs a different mitigation approach.
Radon mitigation is a proven, permanent fix. A well-installed system can reduce indoor levels dramatically, and a follow-up test confirms it is working.

Crawlspace mitigation
A sealed vapor barrier over the soil with suction underneath, common in homes across Huntsville and Madison County.

Radon questions, answered
What level of radon is dangerous?
The EPA recommends fixing a home at 4.0 pCi/L or higher and says to consider fixing between 2.0 and 4.0 pCi/L. No level is considered completely risk-free.
Is radon a problem in Huntsville, Alabama?
North Alabama sits on limestone-rich geology, and Madison County is in EPA Radon Zone 1, the highest-potential zone. The only way to know a specific home’s level is to test it.
How much does radon mitigation cost?
Cost depends on your foundation type, the layout of the home and where the pipe can run. A contractor can give a firm price after reviewing your home, and most will quote at no charge. Get more than one quote if you can.
How long does installation take?
Many installations take a day or less; complex homes take longer. A retest after installation confirms the system is working.
How do I choose a radon contractor?
Ask about radon certification, such as NRPP or NRSB, and about any state or local requirements. Ask what the price includes, whether they retest afterward, and what warranty they offer on the system.
How often should I retest after mitigation?
The EPA recommends retesting at least every two years, and after any renovation that changes your foundation or your home’s airflow.
Do I need a radon test before selling or buying a home?
Radon testing is a common part of home inspections. If a result comes back at or above 4.0 pCi/L, a mitigation system can usually be installed before or after closing.
Does radon get into homes with no basement?
Yes. Slab-on-grade homes and crawlspace homes can have high radon too. Radon moves through soil and enters wherever the foundation has an opening.
