Mold & Mildew Control

How healthy is your home?

Every home in America needs a healthy basement. Over 40% of the air you breathe comes from your basement or crawl space through a natural occurrence called “stack-effect”. It is the natural movement of air in your basement that rises up through your home. It is driven by a difference in indoor to outdoor air density resulting from temperature and moisture differences. Less dense air rises and is replaced by denser, cool air. If the air in your basement or crawl space is not healthy, then the air throughout your entire home is not healthy.

A wet and damp basement or crawl space can create an unhealthy indoor living environment. Even a small corrective step can make a major difference in someone’s home or work place.

The World Health Organization (WHO) published guidelines on indoor air quality reporting that occupants of damp or moldy buildings, both private and public, have up to a 75% greater risk of respiratory symptoms and asthma. Studies have also established an association between indoor dampness with respiratory infections and disturbing the immune system.

Controlling the humidity in your basement or crawl space will help to control the growth of mold and mildew. Both are direct causes of a stuffy nose, irritated eyes, wheezing or skin irritation to those who are sensitive. Mold growth will often occur, particularly if the moisture problem remains undiscovered or unaddressed. The decomposition of organic material caused by mold creates a ‘musty’ smell. The only effective way to control mold is to control the moisture.

Keeping the humidity in your basement or crawl space under 50% is the recommended range to eliminate the growth of mold and mildew. Temperature and humidity sensors with alarms like the one on the left help to monitor changes in the humidity.


Radon is a cancer causing natural radioactive gas that you can’t see, smell or taste. Its presence in your home can pose a danger to your family’s health. Radon is the leading cause of lung cancer among non-smokers. It claims about 21,000 lives annually. Minimize the entry of Radon gas by sealing cracks and openings in the foundation and along basement or crawl space walls and floors. All sump pits and floor drains should be sealed shut.


If you've ever touched a concrete wall in a basement you would know it feels damp and cold. That is because concrete is porous and allows water and water vapor to pass through it.

These vapors contribute to the high humidity levels in basements making them perfect breeding grounds for mold and mildew. Installing a durable vapor barrier against the walls will prevent these vapors from entering your basement and creating an unsafe moisture and humidity level in your home.

A high quality, durable vapor barrier on your walls will direct water down to the drain system below and keeps it off the finished walls of your basement. It will also keep water vapor from getting into the basement environment and lower humidity levels within your home.

The final piece to controlling mold and mildew is the installation of a properly sized dehumidifying device. Pacific Basement Waterproofing exclusively installs the Santa Fe line of commercial dehumidifiers. When properly sized and installed these devices will continually keep the humidity levels in both your basement and crawl space well below the recommended 50% level.
