Homeowners all over the world are more aware than ever of the invisible threats to our health that lurk in our indoor air, which has many homeowners here in Nashville wondering what else the air in their home might contain. Because most of the contaminants that float around us can’t be seen by the naked eye, home indoor air quality testing is one of the only ways to know for sure what you might be inhaling minute by minute, second by second. Here at DocAir, residential indoor air quality testing is a part of our “science first” approach to improving the overall health of your home. However, once we figure out what is in your breathing air, the real work has only just begun.
Exposure to radon gas can cause lung cancer. The higher the concentration, the greater the risk. It is no surprise that homeowners and real estate professionals consider radon to be a terrible thing with no redeeming characteristics. However, there are situations where the discovery of elevated radon levels can show you how to make your home healthier and more energy efficient. Take the case of a home constructed over a vented crawl space. DocAir installs hundreds of mitigation systems each year, many of them in homes with crawl spaces.
If the moisture in your home has not been mitigated, mold has everything it needs to grow, potentially affecting the health of those occupying the home or building. Mold can increase respiratory symptoms associated with asthma, and exacerbate common allergy-like symptoms all year round, so taking care of your mold problem is an issue that must be addressed right away! Here at DocAir, we don’t just get rid of mold – we prevent it from coming back, securing a healthier home for you, your family, or your business.

Our science-first approach is simple: “Keep water away from building foundations.” This is easier said than done, and many stormwater remediation contractors fail to stick to this approach. Through
Vented crawl spaces are a problem. During hot, humid weather, they are a source of moisture, mold, and other indoor air quality problems. Fortunately, a vented crawl space can be converted into a high-performance, moisture-controlled space, and the best news – the cost of the upgrade will pay for itself in terms of energy savings!
