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

In most states, radon testing companies don’t need to be licensed or certified by the state, but the companies that analyze the test results and develop radon mitigation protocols do. You should choose a radon testing company that suits your needs, but before hiring a mitigation specialist, check our state licensing tool to make sure the company is properly certified.

If your home has a sump pit, you can integrate it with a radon mitigation system. You can accomplish this by sealing the pump cover with an airtight lid that accommodates radon vent pipes and sump pump hoses. This allows the vent pipe to redirect the radon gas outside of your home.

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).

It is possible to test for radon yourself using DIY radon test kits, but these at-home test kits should never be a replacement for professional radon testing. DIY test kits can provide some information about radon exposure in your house, but your indoor temperature and humidity can affect the results, as can improper usage of the test kit. You could save yourself some money by hiring a radon professional to begin with, and when it comes to your family’s safety, hiring an experienced professional to do the testing is usually the best option.

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