How can I lower the levels of radon in my house?

Reduction of the radon that enters your house is a fairly simple process. Basically, a vapor barrier is added or improved between the ground and your basement or crawlspace and piping and a small fan is used to reroute the radon laden gas from underneath this vapor barrier to an outside vent on the top of your house. The radon that is already in your house will continue to naturally and quickly decay and will be mostly gone within a week.

Who should I get to install my radon mitigation system?

When you look for a contractor to reduce the radon in your house, look for a contractor who:

  • is NRSB (National Radon Safety Board) & NEHA (National Environmental Health Association) certified. (Will use the guidelines set by the EPA for Radon mitigation in your home.)
  • Knows all the local ordinances regarding radon mitigation, piping, wiring, etc.
  • Has a substantial amount of experience fitting Radon mitigation systems into houses like yours – each house is different and requires subtle but important customizations in your radon mitigation system.

How long does it take to install a system?

A radon mitigation system can usually be installed within one working day.

How expensive are these systems?

Most of the systems we install fall into the $700 to $1700 range.

Is there a guarantee on these systems?

YES! All of our systems are guaranteed to function for 5 years as designed and that the radon concentrations in your house will be reduced to below 4.0 pCi/l (annual average).

How can I be sure the radon level has been reduced?

The EPA recommends a third party test be completed no sooner than 7 days after the work had been completed. However, as part of our installation, we will test your radon levels for you to make sure the system is working properly.
