Should I walk away from a house with radon?

“You should definitely take it seriously but you really don’t need to walk away from the home. It’s actually pretty easy to remove radon, and it’s not that expensive,” Consumer Reports Home Editor Paul Hope said. Home inspections often include testing for radon – using short term kits.

Should I worry about radon in my home?

The simple answer is “yes” – at least trace levels of radon will exist in every home. … That will mean an old home, new home, drafty home, well insulated home and homes with and without basements. If any part of your foundation is in direct contact with the soil, it has the potential of having elevated levels.

What houses are more likely to have radon?

No particular style of home is more likely to have a radon problem; including old homes, new homes, drafty homes, insulated homes, homes with basements, or homes without basements.

Will radon go away?

In some cases, radon levels can be lowered by ventilating the crawlspace passively, or actively, with the use of a fan. Crawlspace ventilation may lower indoor radon levels both by reducing the home’s suction on the soil and by diluting the radon beneath the home.

Where is radon most likely to accumulate in a home?

About one in every 15 homes is thought to have high levels of radon. The highest concentration of radon tends to be found in the basement or on the first floor.

Does finishing a basement reduce radon?

Radon levels are above recommended EPA levels. Radon levels must be reduced even if you are not finishing your basement. … Because it comes from the ground, radon levels are usually highest in basements.

Does radon go through concrete?

Radon, soil gasses, and water vapor will easily pass through any openings, cracks, gaps, drains, or thin concrete (rat slabs) in the basement.

Does sealing a basement floor reduce radon?

Sealing the basement floor can help reduce the amount of radon entering the home. But just sealing the cracks would be unlikely to reduce those amounts in the long term. Sealing all cracks and applying non-porous, thick epoxy coatings (over 10 MILS dry film thickness) would be a better step.

Does a dehumidifier help with radon?

No, buying a dehumidifier will not make radon go away. … Radon must be removed by a remediation method like active soil depressurization (ASD), which ironically has been shown to be even more effective at removing humidity from a home than a dehumidifier in the same EPA study.

Does radon Gas travel upstairs?

Radon is known to be a heavy gas. … Please understand that the radon level can be significantly higher on an upper floor. Even if the radon level is lower on the first floor than say a basement radon level, it could be higher on the second floor. The only way to know is if you test.

How do you eliminate radon?

Active subslab suction — also called subslab depressurization — is the most common and usually the most reliable radon reduction method. One or more suction pipes are inserted through the floor slab into the crushed rock or soil underneath. They also may be inserted below the concrete slab from outside the home.

How common is radon in a home?

Does rain make radon worse?

Wind and rain storms create the largest variables of radon levels when testing for radon gas. Rainier days tend to result in noticeably higher radon levels. This is because rainy days are often coupled with lower barometric pressure.

Is a 48 hour radon test accurate?

“Short-term radon test kits are not effective in measuring radon gas exposure: Findings show radon tests of less than 90 days are imprecise up to 99 percent of the time.” ScienceDaily.
