What Benefits Come From Crawlspaces? 

Humid crawlspaces – Homes built on a crawlspace, as opposed to a Slab or Basement Foundation, have unique properties that have made them a staple in the South for years. As air flows underneath your home in the heat of the summer, cold air from your crawlspace can help keep your home cooler throughout the hotter months of the year. Therefore, This can save money and headaches in heating and cooling yearlong for the average family.  

Additionally, access to the foundation allows for easy repairs and maintenance on plumbing, heating, cooling, and HVAC. Because the homeowner can access these vital systems without the heavy effort of tearing up their floor to see under the house, Crawlspace homes tend to be the most accessible and flexible option of the three types of foundations.  


What Is So Bad About Humid Crawlspaces? 

 When humid air sits in the crawlspace, the humidity affects everything beneath the house. Wood used in flooring can grow ripe with Mushrooms and Mold as the moisture levels facilitate a feeding ground for Fungus. As the fungus spreads, the inhabitants of the home breathe in mold spores and moisture. Therefore, can lead to a variety of health and respiratory issues.
