Crawlspace mold causes musty odors

Crawl Space Mold & Musty Odors

If your crawl space, or entire house smells damp or musty, we have a solution!

Crawlspace MoldMold is present in every home and the outdoors, but without moisture, it cannot grow to harmful levels. Mold needs three things to grow: organic material such as wood, the right temperature range, and moisture. Of these, the only one that can be controlled is moisture.

Your crawlspace is by far the largest source of moisture in your home.  Mold will grow on any of the organic materials in a crawlspace, but mainly the wood floor components.  Mold reproduces by forming spores (like tiny seeds), and disseminating these spores into the air – a common means of exposure for people. Some molds produce mycotoxins, such as the black mold Stachybotrys. Many articles can be found on the effects of mold, and toxic molds.

All year long, mold releases spores into the air of your crawlspace, but the mold doesn’t just stop there.  It travels into the living space. Crawlspace mold spores can enter your home through open cavities in the sub floor for the plumbing and electrical wiring, register vents, inside accesses, and especially the heating and air conditioning system.

Damp, vented crawl spaces have the high humidity levels necessary for mold growth. Humidity levels from 70% to 90% are easily found in crawl spaces — even relatively dry, vented crawlspaces that have never flooded.

Don’t panic, there is a solution that will stop your crawl space from being a welcoming environment for mold growth.  The Crawlspace Company offers crawl space mold removal services and our AmeriBrite Encapsulation system to prevent future mold growth.

Musty OdorsMusty Odors originating from a crawlspace is a common problem. A musty odor coming from the crawlspace is very unpleasant, and no matter how often you clean your home, a musty crawlspace odor makes a home seem dirty. You might not even notice a musty odor in your home if you become accustomed to the odor, but visitors in your home will definitely notice the unpleasant musty smells.

Musty odors are most often attributed to the gaseous byproduct of mold growing in your crawlspace but there can be other sources. Stagnant water that pools in the crawlspace usually doesn’t result in mold growth in the water, but bacteria may grow and produce volatiles with “musty” odors. There is usually a slime on the surface of the water.  After the ground floor of the crawlspace is damp from groundwater, a musty, wet earth odor can seep up into the living space above.

A crawl space drainage system can aid in reducing some of the musty odors from standing water and the wet dirt.
