Radon Mitigation Systems in Chattanooga, TN

High Radon Is a Solved Problem

An elevated radon reading feels alarming, but the fix is mature, mechanical, and permanent. The standard solution — active sub-slab depressurization — has been refined over decades: a suction point is created beneath your foundation, sealed piping routes the soil gas to a continuously running fan, and the radon vents harmlessly above the roofline before it ever enters your living space. Most homes finish under 2.0 pCi/L, and every system we install is guaranteed to bring the home below the EPA action level of 4.0.

What an Installation Looks Like

1. Diagnostic visit. We evaluate your foundation type — basement slab, crawlspace, or slab-on-grade — locate utilities, and run communication tests to find the suction point that will treat the whole footprint. You get a fixed written quote; no allowances, no surprises.
2. Installation (usually one day). A sealed suction point, schedule-40 PVC routing (through the garage, a closet chase, or externally — your choice on aesthetics), an inline radon fan sized to your soil conditions, and a u-tube manometer so you can verify the system is working at a glance. Crawlspaces get sealed vapor barriers with sub-membrane suction.
3. Post-mitigation verification test. A follow-up radon test confirms the new level in writing. If the home isn't below 4.0 pCi/L, we come back and fix it — that's the guarantee.

Why Systems Fail (and Why Ours Don't)

Most underperforming radon systems share the same defects: an undersized fan, a suction point placed where sub-slab gravel doesn't communicate across the footprint, unsealed sump pits and slab cracks that short-circuit the vacuum, or exhaust terminations that let gas re-enter windows. We pressure-test rather than guess, seal the major entry routes as part of every job, and size the fan to measured airflow — which is also why our fans run quieter than the oversized ones some installers default to.

Living With a Radon System

Almost nothing changes. The fan draws about as much power as a light bulb, runs silently from inside the house, and needs no maintenance beyond a glance at the manometer a few times a year. Fans typically last 10+ years and are inexpensive to replace. When you sell the home, an installed, documented radon system is a selling point — buyers' inspectors flag radon constantly, and yours is already handled.
