Radon Mitigation System Installation in Fort Wayne

How a sub-slab depressurization system works

Radon is pulled into your house because the air inside is at slightly lower pressure than the soil underneath, especially in winter. A mitigation system flips that around. The installer cores a hole through the slab, removes a few buckets of material to create a suction pit, and seals a pipe into it. A fan in the attic, garage or outside wall pulls on that pipe all the time, so the soil under your floor ends up at lower pressure than your basement.

Instead of drifting up into the house, the radon goes into the pipe and out above the roof. The installer also seals major openings like the sump pit and large cracks so the fan's suction spreads evenly.

When you need one

The EPA action level is 4.0 pCi/L. If your short-term test is at or above that, the usual advice is to confirm with a second test or go straight to mitigation, especially if the result is well above 4. Many people also choose a system when results sit between 2 and 4, since radon risk adds up over years.

If you're in the middle of a home purchase or sale, you may not have time for a long-term test. In that case a professional short-term test followed by a system and a retest is the common path.

What to expect on install day

Plan on most of a day. The crew will look at the basement or slab, pick the suction point and pipe route, and confirm it with you before drilling. There's some noise and a little dust from core drilling, but no major demolition.

By the end of the day you should have a running fan, a manometer showing suction, labeled pipe, and sealed entry points. The retest is usually scheduled once the system has run at least 24 hours.

Questions to ask the installer

Ask where the pipe will run and whether there's a cleaner interior option. Ask what fan model they use and what its warranty is. Ask if the price includes the post-install test, and what happens if the retest is still high. Finally, ask about any Indiana certification or credentials they hold and confirm their insurance. A good installer answers these without hesitation.
