If your crawl space smells musty, it could be a sign there is excess moisture in the crawl space.
Check the area around the perimeter of your home to make sure your vents and louvers are clear and free of blockages. Look for potential sources of water such as defective sprinkler heads or leaky hoses.
If you cannot correct the musty smell with the steps above, you should consult a professional. If you are within the warrantable period (1 year), contact us.
