Excess moisture in a home can weaken a home’s structure, damage personal belongings, cause unpleasant odors and reduce air quality. A high level of moisture can cause mold growth which can lead to bacteria, cockroaches, and dust mites. This excess moisture can also cause the rotting of a home’s foundation and be the origin of asthma and allergies in the home’s inhabitants.

Moisture can originate from a number of outdoor sources as well as from the activities of those living in the home. Shown in the picture is the EZ BREATHE ventilation system. This can help in the reduction of odors, smells, and reduce humidity in the home as well as the crawl space.

Some outdoor sources include :

  • Foundation drainage

Indoor sources include :

  • Moisture from the crawl space
  • Domestic activities

Excess moisture within a home is not a hard problem to diagnose. There are numerous symptoms that can indicate that there is a high level of moisture within your home.
