What Is Crawlspace Mold Treatment?
Crawlspace mold treatment removes fungal growth from floor joists, subflooring, and other affected surfaces. In North Alabama’s humid climate, crawlspaces trap moisture, creating perfect conditions for mold to grow.
We use professional-grade antimicrobial products to kill mold at the source, and when growth is heavy, we scrub the joists to remove buildup before applying treatment.
Why Mold Is So Common in North Alabama Crawlspaces
High Humidity Levels
North Alabama’s climate keeps crawlspaces damp, allowing mold to grow year-round.
Damp Wood & Insulation
Wet joists, sagging insulation, and high humidity fuel fungal growth.
Poor Ventilation & Airflow
Open vents let humid outdoor air enter, raising moisture levels and creating ideal mold conditions.

Vanguard treated my crawlspace as if it were their own. Josh was incredibly informative and not pushy at all. These are the qualities I look for in a contracting company. If you need any crawlspace work done, give them a call. A plus in my book!
