Crawl Space Flooding: Clean-Up Steps & 5 Preventative Measures

Pooling water in your crawl space is not good, but it sometimes happens when you least expect it. Whether the water is from a heavy rainstorm, a leaky pipe, or a backed-up sewer line, it can lead to considerable damage.  

Installing quality waterproofing solutions is the best way to protect your crawl space. By doing so, it will prevent water damage and preserve your home’s structural integrity.

Here, we’ll cover the problems associated with a flooded crawl space and how our team at Ohio Basement Authority can help you repair and protect your home from future flooding.

• 
  Mold and rot, resulting from moisture in your crawl space, can cause musty smells and health issues.
• Wood rot, caused by lingering water on floors and in crawl spaces, can lead to serious structural damage.
• Damaged fiberglass insulation becomes ineffective when soaked by moisture and rising water.
• Increased pest activity in the crawl space is driven by damp conditions and wood rot.

• Remove the water from your crawl space immediately. For extensive flooding, enlist a professional to pump out the water efficiently.
• Ensure the area is thoroughly dried, including wood framing and the floor above the crawl space, by a water damage restoration service.
• Sanitize the crawl space to halt mold growth, with a professional conducting a visual inspection and cleaning as needed.
• Install a dehumidifier to reduce moisture levels to 50% or below, allowing time for the air to clear.

Melting snow and roof runoff often lead to crawl space flooding, typically caused by inadequate exterior drainage. Inspect gutters and downspouts for damage, and have them repaired by a roofing service.

If your landscaping slopes towards your foundation, indicating a negative yard grade, you risk rainwater and snow pooling around the foundation and causing structural damage. Consult a landscaping company to re-grade your yard for proper water drainage away from your property.

4. Install a Vapor Barrier 

For additional protection, it’s best to encapsulate your crawl space with a heavy-duty, 20-mil vapor barrier. This effectively locks out moisture, wood-damaging pests, and groundwater from your crawl space.  

Cleaning a crawl space after a flood and protecting it from future problems is not your typical DIY job. Along with floodwater, your crawl space could be filled with contaminants like mold and pests. That’s why it’s best to turn to your trusted, local experts.
