Many homes built on crawl space foundations in the United States suffer from poor moisture management. Striving for a healthy home is threatened by crawl space moisture. There are some common symptoms of a crawl space moisture problem. For example, if you notice mold or moisture damage in the crawl space, it has obviously been exposed to moisture. If you smell a bit of a musty odor in your living area, notice condensation on your air conditioning or ductwork, insulation, or water pipes, or see that your hardwood floors are buckling, you may need to have your crawl space looked at. Another sign is if there seems to be high humidity in your home. If your wooden framing seems to be rotting, that’s a red flag. Last, but not least, if you notice insects in your home, especially ones like centipedes, you will definitely want a professional to check out your crawl space.

Mold and Mildew Damage in Crawl Spaces

The symptoms of a faulty crawl space are most often noticed in the humid spring and summer seasons but can occur at any time of the year. Often, the heating and air conditioning contractor is the first person the residents call to deal with the problem. Typically though, the problem is not due to a failure of the air conditioning system; it results from poor moisture control in the crawl space and can be solved by waterproofing contractors.


For many decades, building codes and conventional wisdom have prescribed ventilation with outside air as the primary method of moisture control in crawl spaces. In the humid Spring and Summer, however, ventilation with outside air only makes moisture problems worse. Recent research indicates that a new type of crawl space system, with NO vents to the outside, water drainage, and a heavy ground vapor barrier can provide greatly improved moisture control and significant energy savings when properly installed.

Crawl space vapor barriers are the first line of defense against high humidity and poor indoor air quality. These poly crawl space encapsulation barriers are 10 to 20 mil thick, puncture resistant and made of a high tensile strength material that stops soil moisture from entering the space from the soil. When installed by professional waterproofing contractors, these swimming pool type liners encapsulate the crawl space so that moisture cannot attack exposed wood and create mold and mildew.

These same crawl space vapor barriers can be used on the basement walls to prevent water and moisture permeation through the wall. By continuing the vapor barrier from the ground to up the foundation walls you will create a permanent vapor barrier against most water and water vapor, creating a healthier home environment.

Once the crawl space vapor barriers are in place, the next action is to stop water infiltration through the below-grade foundation walls. This is accomplished by excavating the exterior foundation and sealing the below-grade walls with polymer membrane coating and dimple board. This will stop water from being wicked from the exterior soil into the crawl space. This waterproofing will also direct water down to an installed interior or exterior French drain tile system that can drain to either a sump pump or to daylight away from the foundation.

The final step to waterproofing your crawl space is to seal or close in your crawl space. Crawl space sealing prevents the humid outside air from settling in the space creating condensation and promoting mold growth. There have been many studies done proving that a sealed crawl space creates a healthier and more energy efficient home due to the elimination of humidity fluctuations.

Crawl spaces also have another drawback. They can cause sagging floors. When crawl spaces are constructed, they are supported by piers placed below support beams. Over time, the soils that these piers are supported by begins to settle. The piers then sink into the ground and no longer support the floor above them. This causes the floor to sag. This sagging can cause cracked floor tiles and annoying squeaky floors. To avoid sagging floors, we must be able to support the floors to their original height and make them level.

A deep foundation support system must be installed to create a permanent fix to the crawl space problems. Steel push piers can be driven deep into the soil beneath your crawl space to provide solid and long-lasting support to your floors. You won’t have to worry about your home’s foundation anymore.
