Sub-Slab Depressurization System Installation
This is the core fix for a Jacksonville home with an elevated radon reading. A sealed suction point under the slab, connected to an exterior fan through PVC pipe routed above the roofline, pulls soil gas out from under the house before it can seep up through cracks and utility penetrations. Left unaddressed, an elevated reading doesn’t go away on its own — it stays at whatever level the soil underneath the house is producing, year after year.
Every homeowner needs this if a test comes back at 4 pCi/L or higher. Getting it right turns on a communication test before the suction point is cored, because a slab poured over compacted fill does not spread a pressure field the way one poured over clean gravel does.

Radon Testing
Before any system goes in, we run a certified short-term test so you know your actual number instead of guessing. This is also the service most home buyers, sellers, and real estate agents in Duval County need on its own, without any mitigation work attached, to satisfy a purchase contract contingency.
Skipping this step and installing a system on a home that never actually had a radon problem wastes money on a fan that didn’t need to run. See how radon testing works →

Crawl Space Radon Mitigation
Some of Jacksonville’s older homes, especially in Riverside, Avondale, and parts of Springfield, were built with a crawl space instead of a full slab. Radon moves through open crawl space soil even more easily than through a poured slab, so these homes usually need a vapor barrier encapsulation system paired with a dedicated suction point rather than the standard single-point slab system.
Ignoring a crawl space radon problem also tends to go hand in hand with excess humidity and musty odors indoors. See how crawl space mitigation works →

Radon System Repair & Maintenance
A radon fan is a mechanical part, and like any fan, it eventually wears out, usually after 8 to 12 years of continuous running. A failed fan, a cracked pipe joint, or a manometer gauge reading outside its normal range means the system has stopped protecting the house even though it’s still sitting there doing nothing.
Homeowners who bought a house with an existing system, or whose system alarm is going off, need this service rather than a brand-new install. See how system repair works →

Real Estate Radon Testing
A test that sits in a transaction file has to be defensible, and EPA lays out a specific protocol for that situation: two passive detectors placed side by side, two run sequentially in the same spot, or a continuous monitor — minimum 48 hours of exposure either way, with 12 hours of closed-house conditions before it starts.
That is where deals go sideways. A seller airs the house out before a showing, someone props the back door, an attic fan runs, and a test that a buyer is waiting on gets invalidated on day three of a ten-day inspection window. A documented third-party test with tamper-evident handling removes the argument before it starts.
Plan on three days from call to result, four counting the pre-test closure. Call when the contract is signed, not when the window is closing. See the full transaction protocol →
