Mold in the Crawl Space? Here’s What Causes It and How to Get Rid of It for Good

If your home smells musty or you’re noticing allergy symptoms that won’t go away, it might be time to look below the surface — literally.

Mold loves crawl spaces.

Why? Because the conditions are perfect: dark, damp, and often undisturbed for years.

At PierPoint Foundation Solutions, we see mold growth under homes every week — especially in older properties, flood-prone areas, and places with poor drainage. And when it shows up, it spreads fast.

Here’s what causes crawl space mold, how to tell if it’s there, and what we do to make sure it never comes back.

🍄 What Causes Mold to Grow in Crawl Spaces?

Mold needs just three things to thrive:

1. Moisture

2. Warmth

3. Organic material (like wood)

If you have water intrusion, high humidity, or condensation under your home, it creates an ideal environment for mold spores — which are always in the air — to settle and spread.

🚨 Common Triggers for Mold Below the House

• Groundwater intrusion or poor drainage

• Lack of vapor barrier or broken plastic

• No dehumidifier in a sealed crawl

• HVAC condensation or duct leaks

• Standing water from plumbing leaks or storms

• Open crawl vents letting in humid Arkansas air

🧪 Signs You May Have Mold in the Crawl

Not all mold is visible — some hides behind insulation or inside wood. But there are warning signs:

• Musty or earthy odors inside the house

• Allergy symptoms like coughing, sneezing, or headaches

• White, green, or black fuzzy patches under the home

• Warped or spongy flooring

• High humidity levels (above 60%) in the crawl space

🛠️ How PierPoint Stops Mold at the Source

🧬 Why Mold Matters for Your Health

Even small amounts of mold can:

• Trigger asthma and respiratory problems

• Aggravate immune conditions

• Lower indoor air quality (since up to 50% of your indoor air comes from the crawl)

• Deteriorate wood and structural integrity

It’s not just ugly — it’s unsafe.
