Reasons Why Crawl Space Mold Damage Can Occur

Here are five common causes of crawl space mold in Seattle:

Construction Defects

Poor crawl space construction can lead to mold growth. If there is no airflow or poor ventilation in the space, mold can quickly grow. Cracks and holes in your crawl space can also let water seep in and increase the risks of mold growth. 

Improper Maintenance

If you neglect to regularly clean out or inspect your crawl space after a storm, you might not even be aware of mold growth. Routine inspection of your crawl space can help prevent mold growth from occurring. 


After a storm or hurricane, you should immediately check your crawl space for moisture. Mold can grow in as little as 24 hours after a storm.

Plumbing Failures

Broken pipes can cause water to leak down into your crawl space and cause mold growth. Remember, even a slight drip of moisture can trigger molds.

Appliance Water Line or Drain Line Breaks

Appliances with a water line, such as your dishwasher or washing machine, can cause mold growth in your crawl space if a pipe leaks.
