Veteran owned indoor air quality testing, engineering and consulting firm. Some risks are unavoidable but Indoor Air Pollution is a risk you can do something about. IndoorDoctor engineers test for possible environmental hazards, such as poor air quality. We define your environmental concern, evaluate its significance, and develop corrective actions or preventative plans to reduce the perceived hazard. Our reports are totally unbiased as we are not in the remediation business. For example, we have helped our clients to identify air quality issues that are contributory to ill-health such as molds and allergens. Many of our customers request air quality assessment before investing hundreds of thousands of dollars in a real estate purchase. Other customers use our reports to support insurance claims. But all of our customers want the peace of mind that knowing the air they are breathing is free of environmental contaminates.

"I explained to Jeff that I had bought a new condo, which was new construction, and I had concerns that the HVAC was not properly working and I wasn't getting enough clean air. Jeff was able to come the very next day. He is incredibly knowledgeable and clearly passionate about what he does. He conducted many tests - toxic gas levels, dust, mold, dander, etc. After about 30 minutes of testing, he identified I had a slow gas leak in my gas fireplace, which apparently had not been installed right. He stayed with me while the gas company came to remedy the situation. I am so grateful for him or I would never have known about the leak, which was probably contributing to health issues I was having. He also was able to turn around the other lab results incredibly quickly. Several others in my building have since hired him. Can't recommend him enough."

Radon Detection and Reduction questions, answered by experts

No level of radon is technically safe, but because it’s everywhere—even in the air outside—it’s impossible to avoid entirely. Instead, the Environmental Protection Agency encourages taking preventative measures if the levels of radon in your home rise above 2 pCi/L. (For reference, the average radon level in homes across the United States is 1.3 pCi/L.

DIY kits are available for basic testing. Professional services provide comprehensive results and recommendations.

Properties should ideally be tested for radon every 2 to 5 years or sooner when changes to the property structure or ventilation occur that might impact airflow.

Costs depend on property size, test types, and additional services like mold sampling.

Radon is present almost everywhere but, like sunlight, the concentration levels and how often you are exposed to it have a large part to play in just how dangerous it is. There are levels of radon that are acceptable inside a house, but above a certain limit, radon becomes a serious radioactive hazard that is a known cause of lung cancer. In fact, radon exposure is the number two leading cause of lung cancer (after smoking).
