Risk of structural damage:
Home foundations are more likely to crack, twist, or warp. This can lead to structural problems such as cracked walls, doors and windows that no longer open properly, floors that sag or become uneven, etc.
Humidity issues:
Moisture can easily accumulate under a home without a crawl space. This can lead to the growth of mold and fungus. Therefore, in addition to causing damage to the structure of the house, it can develop health problems for the family residing in the home.
