These persistent smells are not just unpleasant; they are a warning sign of high humidity, water leaks, or even mold growth, which can damage your home’s structure and affect your well-being.

Musty Crawl Space FAQs

No, musty smells are not normal. Many people think musty smells are just part of owning a home with a crawl space, but just because they happen often does not mean they are normal.

DIY methods only provide a temporary solution at best. Even if you use an air freshener or purifier, moisture in your crawl space will only cause the smells to come back; work with a professional to address the water below your home.

Effective moisture control solutions typically lead to significantly less odors in a few days to weeks, as conditions start to improve. However, complete elimination of odors may take a few months.
