Radon Testing & Mitigation System Installation in Indiana
Much of Indiana sits in a high-radon zone. HazMit measures radon levels and installs radon mitigation systems that actively vent soil gas from below the building so indoor levels stay safe long term.
What this service covers
Radon is a colorless, odorless gas and the leading cause of lung cancer among non-smokers. You can't tell it's there without testing, and elevated levels don't fix themselves — they require an engineered mitigation system.
- Short-term and long-term radon testing
- Placement guidance for accurate measurement
- Design of an active sub-slab depressurization system
- Installation of fan, vent piping, and system labeling
- Post-installation retest to confirm reduction
- Documentation for real estate, lending, or facility records

Simple, documented process
- 1
Test
We place testing equipment and confirm the baseline radon level.
- 2
Design
If mitigation is needed, we design a system matched to the foundation and building.
- 3
Install
Sub-slab depressurization system installed with fan, vent stack, and monitoring.
- 4
Verify
Post-installation retest confirms the system is doing its job.
Local coverage across Central and Southern Indiana
We test for radon and install mitigation systems across Indianapolis, Bloomington, Columbus, Greenwood, Franklin, Martinsville, Seymour, Jeffersonville, New Albany, Evansville, Terre Haute, and the surrounding Central and Southern Indiana region.
Common questions
What radon level requires mitigation?
EPA recommends action at 4.0 pCi/L or higher, and encourages consideration between 2.0 and 4.0 pCi/L. We'll explain your specific result honestly.
How long does installation take?
Most single-family installations are completed in a day. Larger or complex buildings take longer and are quoted after a site visit.
Do you retest after installing the system?
Yes. A post-installation test confirms the system reduced radon below the action level.
Is radon really a concern in Indiana?
Yes — a large portion of Indiana is in EPA's high-radon Zone 1. Testing is the only way to know your building's level.
