Crawl Space Moisture in the Pacific Northwest: Signs, Risks and Solutions

Experts estimate that an unsealed crawl space may contribute to more than half of your home’s breathable air supply. As a result, any air issues in your crawl space can significantly affect your home’s overall indoor air quality. For this reason alone, keeping your crawl space clean and healthy is essential. In the Pacific Northwest, including Portland, Oregon, crawl space moisture is a serious problem for older homes. Here’s how to solve these problems.

The Problem With Excessive Moisture

This region’s heavy rainfall and poor grading require careful management to avoid problems like:

• Foundation settling: When crawl space moisture is severe enough, it can cause foundation settling by eroding, saturating or shifting the soil beneath the building supports.
• Mold and mildew: Humidity and moisture buildup in your crawl space create an ideal environment for mold growth, which can lead to health-related concerns and issues.
• Structural damage: Excessive moisture can cause water damage to supports and other building elements. Mold in the crawl space exacerbates it, leading to costly repairs.

Since most Americans spend 90% of their time indoors, the decrease in air quality due to damp, moldy crawl spaces can have significant effects.

What to Look for in a Crawl Space Inspection

If you suspect moisture issues in your crawl space, a basic DIY inspection is a great place to start. Look for signs of excessive moisture, like:

• Soil erosion
• Musty smells
• Allergy symptoms
• Increased energy bills
• Visibly standing water
• Wood rot or warped floors

If any of these are present, it’s time to seek professional assistance.

Potential Solutions

The cost of encapsulation and other solutions is often much lower than the cost of repairs later. Popular crawlspace solutions include:

• Sump pumps: If your crawl space or basin floods regularly, a sump pump installation will actively remove the water.
• Low-point drains: Need drainage for foundation settling issues? A low point drain provides passive relief by redirecting water.
• Pipe and rock drains: These systems redirect water in poorly draining soils, guiding it away from your home’s foundation.
• Crawl space restoration: When your wet crawl space has an issue, restoration is the ideal solution to bring it back into shape.
• Crawl space encapsulation: Encapsulation involves installing a moisture barrier and a dehumidifier to remove excessive moisture.
