Prevent Mold and Mildew From Growing In Your Home!

Indoor Air Quality

When your home has bad indoor air quality, it can lead to a variety of health problems, including infections, lung cancer, or even various respiratory problems including frequent asthma attacks. It can also cause headaches, nausea, fatigue, dry eyes, skin rashes, and many other unfavorable medical conditions you and your family should never have to deal with. The American Lung Association says that the first line of defense against pollution in the indoor environment is to be sure that the pollutants have no way of getting inside to begin with.

With the right types of ventilation in your St. Louis area home, you and your family can breathe fresh, clean, and healthy air. At Greenmark Home Performance, we have a team of professionals who will be able to assist you with determining what types of ventilating systems will be necessary, whether you need a whole-home dehumidifier, or exhaust fans in the kitchen or bathroom, we can help.

Common Air Pollutants


This includes mold, bacteria, pollen, pet dander, and viruses. Problems here can lead to asthma attacks, allergic reactions, and other medical problems. To help alleviate symptoms, bedding can be washed, animals can be kept out of areas where people spend the most time or sleep, and thorough cleaning of all surfaces should be done to prevent dangerous mold growth.

Secondhand Tobacco Smoke

This contains over 200 poisons, including formaldehyde and carbon monoxide. It also contains 60 different chemicals which are linked to cancer. In the U.S. every year, this problem is known to cause around 3,000 deaths in non-smokers and nearly 50,000 heart disease deaths. It proves to be especially problematic for the young, including children and infants who often will suffer from recurring pneumonia, respiratory tract infections, and ear infections.


This comes from fuel burning stoves, furnaces, fire places, and water heaters. The most dangerous type of combustion pollutant is carbon monoxide since it can't be seen, tasted, smelled, or really even noticed at all until it starts to cause serious health problems, including: fatigue, headaches, confusion, nausea, and dizziness. In extreme cases with very high levels of carbon monoxide, some individuals may lose their life.


This is a naturally-occurring radioactive gas which is able to get into a home through cracks and crevices in the foundation. It is the leading cause of lung cancer in non-smoking individuals in the U.S. To reduce the levels of Radon in a home, testing and remediation work will need to be done.


This is a non-flammable mineral which can produce very tiny fibers. When breathed in over a long period of time, the fibers can actually scar lung tissue. Many asbestos products in a home include flooring materials, insulation, and heating equipment. An air-tight seal of the home's building envelope is needed and removal of dangerous materials will be required for this pollutant.


This is a common chemical that is found in adhesive or bonding materials, such as in carpets, upholstery, and particle board. When it is released into the air, it can cause coughing, eye and throat irritation, and even cancer. To reduce your risk of these problems, minimize your use of products containing the chemical.
