Texas Radon Mitigation Cost by County, Foundation, and Rules
Compare typical local price ranges for basement, slab, and crawl space systems. Use the state-level ranges first, then open your county when you need a local estimate after a confirmed radon result.
Fastest Start
Use ZIP Instead of Scrolling
If you know the property ZIP, jump straight to the right county estimate instead of browsing the full state list.
Cost Basics
Foundation & Result Ranges
Use the national cost guide if you need basement, slab, crawl-space, or 4.0+ result context first.
Validate the Risk
Check TX Radon Levels
If you do not have a confirmed radon result yet, review EPA zone context before you compare mitigation pricing.

Jump to County Pricing
Open your county if you already know the area and just need a local basement, slab, or crawl-space price range.
Official State Resource
Texas radon program and rules
Use the state program link to verify local radon guidance, disclosure language, and contractor credential expectations before you act on an estimate.
Disclosure note
Texas does not have specific radon disclosure requirements. Most Texas counties are in EPA Zone 3 (low risk), but isolated areas can have elevated readings.
Credential note
Texas does not require state licensing for radon professionals.
TX Cost Starting Point
Texas cost range by foundation
Basement
$890-$1583
Use this when the home has a basement or lowest-level slab that supports a standard sub-slab suction system.
Slab-on-Grade
$841-$1485
Slab homes can price differently when finished space, routing, or core drilling complicates the system path.
Crawl Space
$1388-$2530
Crawl-space jobs can move higher when vapor-barrier sealing, access, and sub-membrane suction add labor.
State rules that can change the quote

Open a Texas county page for local pricing
County pages narrow the state range with local EPA zone context, housing data, state rules, and the foundation scenario you choose.
Why Does Cost Vary in Texas?
Price ranges across Texas move with local labor rates, permit friction, roofline routing, and foundation type. County pages narrow this down for homeowners comparing basement, slab, or crawl space mitigation after a confirmed radon reading.
