Indoor air pollutants have increased widely over the past years for variety of reasons. The contributing factor to indoor air quality issues in our homes today are the construction of more tightly sealed buildings, reduced ventilation rates (in order to save energy), the wide use of synthetic building materials and furnishings throughout our tight homes, and the increased use of chemical products such as pesticides, housekeeping supplies, and our personal care products.
The major factors that are really affecting our indoor air quality today are...
Moisture and Biologicals - Moisture problems in our homes can result in the growth of biological and microbial organisms like mold, mildew, dust mites and pet dander. Exposure to these organisms can increase the risk of allergic illness, cause respiratory infections, trigger asthma, or even have other health effects. Common sources of moisture in our homes include high indoor humidity, and moisture leaks that we don't even knowe are occuring. A poorly maintained heating, ventilation and air-conditioning systems can contribute to excessive moisture accumulation within your home. To remedy this widespread problem, the source of excess moisture must be located and repaired, and then the contaminated materials must be removed and discarded if they can not be properly cleaned.
Combustion Products, including Carbon Monoxide

I just wanted to write and thank you very much for doing our inspection today. You really took an awful lot of extra time to explain things to us. It was a huge help and by far my favorite part of this whole home-buying process. In addition to drawing our attention to the major projects that need to be undertaken right away or in the near future, I was glad that you were also so thorough as to point out smaller things and provide suggestions for fixes that we'd be able to do ourselves. Thanks again for all your effort. I'm finding your "Know Your Home" book a great source of information along with your report. I'll no doubt have some questions for you at some point and really appreciate your willingness to answer them. Have a great rest of your weekend!
