Spring Valley and Jamul are known for their mild climate, but even in areas with warm temperatures, weather patterns like heavy rain, high humidity, and sudden temperature drops can create the perfect conditions for mold to thrive. When the wet season hits, moisture can seep into your walls, floors, and ceilings, allowing mold spores to grow and spread quickly.

Humidity is a significant factor in mold development, especially during the late spring and early fall when rain is more frequent. Homes that don’t have adequate ventilation or drainage systems can trap moisture, turning attics, basements, and crawl spaces into mold breeding grounds. Even though Spring Valley doesn’t face severe storms like other parts of California, it’s still essential to be aware of how local weather can impact your home’s vulnerability to mold.
