10 Signs and Symptoms That You Need to Have Your Crawl Space Inspected.
Many homeowners can’t or don’t go into their crawl space. Often, they won’t know if there is a problem in their crawl space until a pipe bursts, the termite company sees moisture related issues, or when servicing is needed for their HVAC system.
How can a homeowner tell there is a bigger issue in the crawl space without ever going underneath the house? There are several signs you might notice that could signal you need to have a professional inspect under your home.
Most homes are built on a vented foundation with a thin 6-mil vapor barrier covering the majority of the ground. Fiberglass batt insulation is installed between the floor joists, and the vents are left open for ventilation. This means that warm air carrying moisture is pouring into the crawl space during the spring and summer months. The crawl space is typically cooler than the outside air. As outside air enters, it’s cooled down and the moisture content of the air in the crawl space increases. Condensation occurs on the cool surfaces in the crawl space such as floor joists, fiberglass insulation, block walls, and the vapor barrier. As this moisture collects on organic materials, the combination of high humidity and warm temperatures will create the ability for mold to grow. The air pouring into the crawl space is being sucked up into the home through a process called “The Stack Effect.” This pulls the moldy, musty, humid air from your crawl space into your home.
As all of this happens you may begin to notice some of the 10 symptoms listed above. Mold/mildew and moisture in your crawl space can have an impact on the integrity of your home by promoting wood rot on joists, if there is bulk water entering the crawl space, it can affect your foundation, and mold/mildew spores can be carried into your home reducing your indoor air quality and agitating asthma and allergies.

If you experience any of the above symptoms, be sure to contact a professional crawl space company to do a thorough inspection. Letting these problems go, typically only causes more problems in your home and becomes more costly to fix over time.
