Radon Mitigation and Testing   •   Mold Mitigation

CJ Development is a general contractor certified by the National Environmental Health Association (NEHA) for testing and mitigation of environmental health hazards. We do the radon testing, radon mitigation, mold mitigation, and methamphetamine testing that will keep your home or commercial building safe.

Radon Mitigation and Testing

Radon is a cancer-causing radioactive gas that’s produced when uranium in soil, rock, and water breaks down and is released into the air, and then get into your home through the foundation.

Methamphetamine Testing Because radon is odorless and invisible, you may not know if you have unacceptable levels in your home.

About 40% of homes in Colorado are located where radon may be a problem, which is more than most states.

We follow the Environmental Protection Agency's Recommended Residential Radon Mitigation Standard of Practice for residential radon mitigation. Any mitigation measures we take or system we install in your home will conform to Colorado regulations.

After we evaluate your radon problem, we'll give you a detailed, written proposal describing how your radon levels can be lowered.

Mold Mitigation

CJ Development can fix your mold and moisture problem. We will identify and eliminate the source of the moisture that lets mold grow in your home.

Mold Mitigation

CJ Development can perform the following services for you:

  • mold remediation and mitigation
  • preventive maintenance that can keep mold from coming back

Methamphetamine Testing

Radon Testing and Mitigation CJ Development inspects and tests for methamphetamine.

Meth labs have been found in single family dwellings, mobile homes, motels, and in cars and trucks — in cities and towns, in the suburbs, and in remote rural and mountain areas.

We test for meth, and we usually begin by wiping suspect surfaces and sending the samples to an accredited laboratory. If we find a problem, we refer you to an industrial hygenist for further testing and recommendations.
