Indoor Air Quality
An essential component of enhancing your home's performance is improving indoor air quality. A well-sealed, well-ventilated home reduces the amount of indoor pollutant levels that can affect your family's health. Wisconsin Home Improvement home performance audits include several tests to assess your home's indoor air quality and identify areas that need attention.
What Are the Sources of Indoor Air Pollution?
The substances that cause indoor air pollution take many forms: gases, contaminants/particulates, mold, bacteria and more. Some common indoor air pollution components include:
- Carbon Monoxide
CO is produced through combustion from furnaces, gas-fired water heaters, gas cooktops and wood-burning stoves. This gas is odorless and can build up in homes that are not properly ventilated.
Radon is another dangerous gas that can invisibly build up inside homes. It seeps into basements and foundations. Radon is known to cause lung cancer, but is easily mitigated if identified through testing.
Allergens can include seasonal pollen and dust mite dander, which can affect family members who have allergies and asthma. Homes that are not well-sealed can allow these particles to enter the home, while poor ventilation can circulate them throughout the house.
Mold develops in poorly sealed or poorly ventilated homes when moisture is allowed to build up from leaks, condensation and humidity.
Home Performance Audits Target Indoor Air Pollution
Wisconsin Home Improvement's inspection can improve home air health by identifying areas in the home that contribute to poor indoor air quality. The elements of the home assessment that address indoor air pollution include:
- Blower door testing assesses the building's tightness, or how much it leaks. When paired with infrared thermal imaging to identify where leaks and gaps are present, the blower door test can help to seal out airborne allergens like pollen.
- Combustion safety testing looks at carbon monoxide levels in flues and other ventilation from furnaces, water heaters and gas cooktops.
- Radon testing identifies the presence and levels of radon in a home. A testing unit is left in a lower area of the home for at least 72 hours and is then analyzed for levels of radon.
