Crawlspaces and High Humidity: When to Take Action

crawlspace humidity

Crawlspaces are an integral part of many homes, providing access to essential components like wiring, plumbing, and insulation. However, when a crawlspace reaches 100% relative humidity, it can lead to a host of problems that every homeowner should be aware of.


Candid Home Inspections LLC is no stranger to the issues that arise from crawlspaces with high humidity levels. With a strong reputation as a veteran-owned business and a five-time recipient of the “Community Choice” award in Spartanburg, SC, Grant and his team have encountered and addressed these challenges numerous times.


One of the primary concerns associated with a crawlspace that has reached 100% relative humidity is moisture-related damage. Excessive moisture can lead to the development of mold and mildew, which not only compromise the structural integrity of the home but also pose health risks to its occupants. Mold spores can become airborne, causing respiratory problems and allergies.


Furthermore, high humidity in the crawlspace can lead to wood rot. The wooden beams and subfloor in your home’s foundation are at risk when moisture content is consistently high. This not only weakens the structural support of the house but also attracts pests like termites and carpenter ants.


To combat these issues, Grant and his team at Candid Home Inspections LLC recommend taking proactive steps. Proper ventilation and insulation are key to regulating humidity levels in the crawlspace. Installing a vapor barrier can also help prevent moisture from seeping into the space from the ground.
