Why Your March "Spring Cleaning" Needs to Start in the Crawl Space

When Hudson Valley homeowners start thinking about spring cleaning in March, the focus is usually on decluttering the garage or deep-cleaning the kitchen. However, if your home has a dirt crawl space, your spring cleaning should actually start below your feet.

As the weather fluctuates, your damp, vented crawl space becomes a major source of poor indoor air quality and high energy costs. This is due to a building science phenomenon called "The Stack Effect."

Understanding the Stack Effect

In March, you are likely still running your heat. As the warm air rises and escapes through your attic, it draws air up from the lowest part of your home—the crawl space. This air isn't empty; it brings with it:

• Misty, humid air that makes your home feel clammy.
• Musty odors from decaying organic matter in the soil.
• Mold spores, which thrive in damp environments.
• Radon gas and other soil gasses.

Essentially, you are breathing whatever is in your crawl space.

Encapsulation: The Ultimate Solution

Traditional venting which was long thought to "dry out" a crawl space actually causes more problems, especially during the humid spring thaw. The real solution is Crawl Space Encapsulation using a system like our 20-mil CleanSpace® vapor barrier.

Encapsulation completely seals your crawl space from the earth. By adding a vapor barrier, blocking vents, and installing a specialized dehumidifier, you transform a nasty crawl space into a clean, dry, conditioned area.

This doesn't just improve your air quality; it also reduces your energy bills. Heating and cooling "leaky" air from your crawl space is expensive. A sealed space is an insulated space.
