Quick Answer: How Do You Reduce Radon Levels In A Home?

Is a radon level of 5 bad?

The best radon level measurement would be zero.

The average global outdoor radon level varies between 5-15 Bq/m3, equal to 0.135-0.405 pCi/L.

For every 99.9 Bq/m3, or every 2.7 pCI/L increase in long term radon exposure, lung cancer risk rises 16%4..

Is it safe to live in a house with radon mitigation?

The EPA estimates that a radon removal system costs about $1,200 for an average house. … Once installed, a follow-up radon test is done. Even in houses with extremely high radon levels, you can expect a drop to levels considered safe.

How long does it take to remediate radon?

The radon removal process can be completed in one day. The typical amount of time to install a mitigation system is anywhere from 3-5 hours. The time will vary depending on the layout of the home and the difficulty of the job.

How do you eliminate radon?

In some cases, radon levels can be lowered by ventilating the crawlspace passively (without the use of a fan) 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 house.

How do you fix high radon levels?

A radon mitigation system consists of a vent pipe, fan and the proper sealing of cracks. This system collects radon gas from underneath the foundation and vents it to the outside of your home. Contact your state radon office for a list of licensed radon mitigation professionals in your area.

How much does it cost to fix high radon levels in home?

Can you reduce radon by opening windows?

Opening windows improves air circulation and ventilation, helping move radon out of the house and mixing radon-free outside air with indoor air. … Opening basement windows helps reduce negative air pressure, diluting radon with clean outdoor air.

Do air purifiers reduce radon?

Air Purifiers are great for mold, dust, allergies, bacteria and viruses, and odors, but many people do not know that they can also help with toxins, gases and chemicals such as radon. The most important type of air filter to reduce radon levels is an activated carbon filter.

Does a dehumidifier reduce radon?

A radon remediation method like ASD will not only reduce radon levels in a home, but it will also dehumidify the home. A dehumidifier, on the other hand, won’t have any meaningful impact on radon levels. In fact, a dehumidifier was only able to achieve 8% to 25% of the moisture capacity that the ASD did!

What time of year are radon levels highest?

Radon levels can vary by season, with the highest levels typically occurring during the months that we heat our homes. That means that even if your home’s radon was below the EPA’s suggested action level of 4.0 picocuries per liter of air during the warmer months, it could be above that level during the winter.

How do you reduce radon levels in your home?

In some cases, radon levels can be lowered by ventilating the crawlspace passively (without the use of a fan) 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 house.

Does radon mitigation decrease home value?

It does the job. Having an active Radon mitigation system in one’s house does not adversely affect the home’s resale value and since Radon is so easily controlled once it’s detected it is no reason not to buy the property if all other factors line up favorably for buying the house.
