High Radon Levels & Remediation Processes

If you recently took a radon test and discovered you had high Radon gas, what should you do next? Do not panic, high radon can be common.

If you do not know anything about radon or are considering a test, read this guide to radon. Find a radon inspector here.

What is considered high radon gas levels?

Any reading reporting more than 2 pCi/L should consider remediation. Any reading over 4 pCi/L should definitely have remediation.

A test by a professional can give you this information if you have not received it already.

Getting Started on Remediation

Finding a Contractor

So if you need Radon remediation, it can be completed by a licensed contractor. Typically, states require licensing or certifications. You can check with your states authority to find out what requirements there are.

If your state does not require licensing or certification, check with the companies you are inquiring about. Typically, the companies can hold certifications by third party entities.

The Repair Cost

The cost to remediate is not terribly expensive, however, it is a chunk of change.

It can vary from $1,200 to $3,000. Once remediation is completed though, you will not have to worry about it again.

After the process is complete, homeowners see a 99% chance of the high radon levels never returning!

Remediation Processes

Diagnostic Tests

Your contractor may have to perform tests in order to find the best way to treat for Radon.

One test is through smoke. The smoke shows air movement and can give clear signals on how the gas is entering the home and staying in the home.

Another test is using vacuums and chemicals. By sucking air from one side of the soil/home and inserting chemicals on another, a contractor can understand if adding vents in particular areas might function the best.

Types of Remediation

The EPA recommends the process of soil suction. Soil suction creates vents (pipes) from underneath the home to the exterior which never allow the radon gas to enter the home. Through this, Radon is quickly diluted into the air.

Your type of remediation depends on your home structure type.

Types of Structures and Effects of Radon Remediation

Basements & Slab on Grade Homes – Basements would require soil suction or pipes through the slab to the exterior.

Crawlspace Homes – crawlspace homes can easily be fixed by using a large layer of plastic. A plastic sheet is laid across the ground and then fans/pipes ventilate the Radon from underneath. The vents allow the Radon to be diluted into the air rather than underneath the home.

From the EPA

Other Types – In other situations and on top of the ones noted above, a contractor may seal cracks. Moreover, the contractor may add other fans to depressurize rooms or a heat recovery ventilator (HRV).

After Remediation of High Radon Gas

After everything is completed, you should request another radon test to ensure the system works.

Also, you may notice your utility bills increase a tad bit. Having extra fans or perhaps vents in your home, may require the AC, heat, or electricity to run a little bit longer.

Will this affect the value of your home?

In short, the answer is no. Professional repairs of Radon actually can increase the value of your home since the new home buyer never has to worry about it.

Here is a post even from Consumer Reports about Radon affecting the price of your home.
