Mitigation & Maintenance
ARS specializes in one thing: installing and maintaining the systems that eliminate elevated radon in your home.
Testing Is Step One
Radon testing reveals the problem. Professional testing uses calibrated devices placed in your home for 48 hours (short-term) or 90+ days (long-term). The results tell us:
- Your current radon levels (measured in pCi/L)
- Whether mitigation is needed (the EPA recommends action at 4.0 pCi/L)
- Where to place the mitigation system for maximum effectiveness
Testing should always be performed by a certified professional. ARS does not perform testing directly, but we can refer you to certified testers in your area.
Mitigation Systems
Sub-slab depressurization is the gold standard for radon mitigation and the most common solution for Illinois homes. We design and install a system custom to your home's construction, foundation type, and radon levels.
- Sub-slab depressurization (SSD)
- Block wall suction systems
- Crawl space encapsulation + venting
- Sump pump integration
- System monitoring with U-tube manometer
- Post-install verification test referral
All Illinois mitigation systems must be installed by a certified mitigator. ARS holds a current state license.

System Maintenance
Radon mitigation fans typically last 5–10 years. Annual inspections catch problems early. We service all brands and can replace fans, reseal pipes, and verify your system is still performing correctly.
- Annual system inspection
- Fan performance testing
- Fan replacement (all brands)
- Pipe sealing & repairs
- Suction point optimization
- Written service report
If Your Radon Fan Gets Loud, It May Be Time for Replacement
Radon fans run 24/7 and typically last 5–10 years. A healthy fan is quiet. If yours is rattling, humming louder than usual, or vibrating the pipe, the bearings are likely wearing out. We service all brands and most replacements are done in a single visit.
Bearings wear over time. A fan that used to hum quietly and is now audible from inside the house usually needs replacement.
If the pipe or wall is vibrating, the fan is working harder than it should. Catch it before it fails entirely.
We replace RadonAway, Fantech, Festa, and any other fan brand — not just systems we installed.

How It Works
Radon is a naturally occurring gas that enters your home from the soil. Here's how it gets in — and how we get it out.
Without a mitigation system, radon rises from the soil into your home. With one, it's drawn out beneath the slab and vented safely outside.
How Radon Enters Your Home
Radon gas forms naturally in soil and rock as uranium breaks down. It migrates upward through the ground and enters homes through openings in the foundation — including basement floor cracks, sump pump openings, crawl space floors, and gaps around pipes.

- →Crawl space soil
- →Gaps around utility penetrations

How Mitigation Works
Sub-slab depressurization is the most effective radon mitigation method. We create a collection point beneath your foundation, run a PVC pipe up through the home, and install a quiet fan unit that continuously draws radon from the soil and vents it safely outside — above the roofline, away from windows.
