Quickly Kill Mold: Crawl Space

Crawl spaces are excellent storage areas. However, one downside to having a crawl space is mold.

This article explores how to kill mold in crawl space areas. We’ll walk you through using DIY and professional methods.

What Are the Causes of Dangerous Mold in a Crawl Space?

Basement Cracks and Flooding

Basement cracks or openings allow moisture to penetrate this enclosed space. Even a small crack can cause mold to thrive.

Plumbing Leaks

Leaky pipes or other damaged plumbing equipment raise moisture levels within the crawl space. In turn, the moist environment quickly promotes mold growth.

Condensation

Moisture in the air condenses into water droplets settling on surfaces. These droplets subsequently attract black, white, and yellow mold in crawl space surfaces.

Poor Ventilation

Lack of ventilation causes humidity levels to rise. These damp surroundings create the perfect environment for mold to grow.

What Are the Signs of Having Mold In Your Crawl Space?

Dark Stains

Fuzzy, slimy, or powdery patches and stains on your crawl space walls, posts, or floor joists are sure signs of mold growth.

Mildew Smell

An unpleasant mold or mildew odor on the first floor is due to mold growth.

Hot and Stuffy Air

Increasing humidity levels within your mold crawl space is a major cause of mold growth.

Frost Buildup or Roof Sheathing

Efflorescence on concrete foundation walls or roof sheathing comes from rising dampness levels usually accompanied by discoloration.

Roof Leaks

If your crawl space has leaking pipes or wall cracks letting in water, it can incubate mold growth. This situation could eventually lead to roof leaks.
