Radon Mitigation in Soddy-Daisy, TN

Soddy-Daisy is a Hamilton County city north of Chattanooga, up the US-27 corridor toward the Sequatchie Valley side of the Tennessee River. Homes there run from lake-area houses and older ranches to newer neighborhoods on sloping lots. We serve Soddy-Daisy from Chattanooga. We do not run an office in town, so we set visits by phone and come to you.

Why a Soddy-Daisy house needs its own test

Radon is a gas that comes out of the ground. It rises into a house through the slab, the cracks, the sump pits and the gaps around pipes, and it collects wherever air is trapped. Whether a given home has a problem depends on the soil and rock beneath that lot and on how the house is built. Two houses on the same street can read very differently. The only way to find out is to measure the one you own. You can see how readings are explained on our radon levels page.

Things we look at on a hillside or lakeside lot

Many lots near the lake and the ridges here have a basement or a partial basement cut into a slope, or a crawl space on a block foundation. Each one changes the plan:

Walkout and full basements. The slab is the main route in, so we look at sumps, floor drains, the joint where wall meets floor, and any old cracks.
Crawl spaces. We seal a heavy plastic sheet over the ground and pull air from beneath it, which usually does more than treating the rooms above.
Slab on grade. A pipe goes through the slab, or beneath it, into the gravel and soil below, and a fan vents the gas above the roofline.

Rock close to the surface can make it harder to pull suction evenly under a slab. When we see that, we say so and plan the suction points accordingly.

When people in town call us

Buying a house. A radon test is often part of the inspection period. If the result is high, you have a repair to negotiate. Our real estate radon testing page explains how the timing fits a contract.

Selling a house. A buyer's test that comes back high can stall a closing. Testing yourself first gives you time to fix it quietly.

A friend's result. Someone on your road found a high number and now you are curious. That is a fine reason to test.

Finishing the lower level. If you are turning a basement into living space, we would rather test before the walls go up. Our guide on finishing a basement covers that case.

What a fix looks like

Most systems are a vent pipe, a quiet in-line fan and a gauge that shows the system is working. Installation is typically a one day job. After the system runs for a while we retest to confirm the number came down, because the retest is the proof that it worked. Details and typical ranges are on our mitigation page, and our cost guide covers what drives the price.

The testing step

Closed-house conditions matter for a short-term test: windows and exterior doors shut, and no whole-house fan running. We place the monitors in the lowest lived-in level, away from drafts, and leave them for the required period. If you want more detail, see our radon testing page.

Local building questions

If your project involves a permit, such as finishing a lower level or building an addition, ask the City of Soddy-Daisy or Hamilton County, whichever applies to your address, what they require. We can tell you what the radon side of the work needs, but we do not set permit rules.
