Radon mitigation costs in Colorado

Radon mitigation costs in Colorado are not prohibitively expensive. However, mitigation costs due vary depending on the home's size, design, foundation (and number of foundations), construction materials, and local climate. Colorado homeowners can install a radon mitigation system for between $400-$500. Nationally, professionally-installed radon mitigation system costs average $1,200, but range from $850 to $1,500 in Colorado, assuming there aren't any problems encountered during installation.*

Do-it-yourself testing kits in Colorado range from $10-$50. Home inspectors and radon measurement contractors can perform this service for you if you don't want to do it yourself. Hiring a professional to test for radon in your home will cost more, perhaps upwards of $150.

Costs are highly dependent on what is required to vent the radon and how to route it through the house. Keep in mind, you will have operating costs associated with radon mitigation, too. Most of these costs come in the form of electricity to run the fan and potentially added heating and cooling costs due to the venting.

Financial assistance for radon mitigation is available to Colorado homeowners through the Colorado Department of Local Affairs — Home Rehabilitation Programs and the U.S. Department of Energy — Office of Energy Efficiency and Renewable Energy.

Radon System Installation

Colorado allows homeowners to install their own radon mitigation systems, but it is best to have a professional that specializes in residential and commercial radon services install your radon mitigation system. Sealing cracks or venting the home from the lowest level alone won't remove radon effectively, nor will simply laying a plastic sheet over the foundation of the home. For the most effective removal, sub-slab depressurization is required. That means drilling through the foundation deep enough to capture radon off-gassing and venting it out of the house using powered fans, which must be connected to your electrical system. This is not a simple do-it-yourself project and with your lung health on the line, you want it done right the first time.

Effectively lowering high radon levels is the goal of any radon mitigation system. This requires special knowledge and expertise that only radon mitigation contractors have. Many homeowners have actually ended up increasing their radon levels due to poor installation.

You can find a qualified radon mitigation contractor at the Colorado Department of Public Health and Environment. These contractors have met state requirements for radon mitigation systems, ensuring your safety.
