What is Radon?

Radon is a naturally occurring colorless, odorless, radioactive gas. It forms from the decay (break down) of the radioactive element, uranium, which is found in soil and rock, right here in Arizona.

Is there Radon in Arizona?

EPA classifies Arizona as Moderate Potential: all Arizona counties have a predicted average indoor radon level between 2 and 4 pCi/L. 

Is Radon dangerous?

Based on the American Cancer Society, elevated levels of radon over an extended period of time can cause lung cancer. 


How to mitigate Radon in your House?

After calling an expert company like us, we will visit your house and evaluate the best solution to mitigate the radon. The most common approaches are active soil depressurization (ASD) and mechanical ventilation (MV). According to the EPA's "A Citizen's Guide to Radon", the method to reduce radon "primarily used is a vent pipe system and fan, which pulls radon from beneath the house and vents it to the outside", which is also called sub-slab depressurization, active soil depressurization, or soil suction.

Reliable techniques exist for reducing radon levels in homes. Experience with radon mitigation systems has developed to the point that virtually any home can be fixed.

Radon reduction requires more than just sealing cracks in the foundation. In fact, caulking and sealing of foundation openings, on its own, has proven not to be a reliable or durable technique. However, sealing is done in conjunction with other mitigation steps.

There are three important elements you should take in consideration when you choose a company:

  • Professionalism: it is important they know what they are doing and they do a professional job
  • Certification: there are radon certification programs, make sure the company has its certification
  • Experience: each house is different, if the company has experience, it can easily understand and provide a mitigation strategy to address the elevated radon issue

Frequently Asked Questions

EPA classifies Arizona as Moderate Potential: all Arizona counties have a predicted average indoor radon level between 2 and 4 pCi/L. EPA also recognizes there are some hot spots though and EPA recommends that all the houses must be tested.

Radon gas comes from the soil that is in direct contact with our home’s foundation. Our home breathes in and out and as our home takes air in, in can pull radon gas into the home through cracks in floors or walls; construction joints; or gaps in foundations around pipes, wires, or conduit. Any hole can be an entrance for radon in our home.

As a licensed contractor, we provide a two year workmanship warranty and in most cases guarantee to get your indoor air radon levels below the EPA safe level. Once the mitigation system has been installed, an initial short term radon test should be done to verify the mitigation system is working and lowering indoor air radon levels.

If I build a new house, is there still the danger of radon? YES Newly built homes are not risk free. Many construction companies and architects are not fully aware of the radon issue. You can ask a radon certified consultant to analyze your project and suggest building techniques during construction on how to prevent radon intrusion.
