The Crawlspace Problem

One of the biggest issues facing homeowners in East Tennessee is moisture in their crawlspace. Most homes in Knoxville are designed with open crawlspaces, an area below the house with vents allowing outside air to enter. These homes need a crawlspace encapsulation system installed.

In the summer, warm moist air is drawn into the crawlspace and then up into the house. In fact, up to 60% of a home’s air enters through the floor from the crawlspace. This can cause problems in the crawlspace and inside the living area as well. Why? Because the air in most crawlspaces is not healthy.

Crawlspaces are usually full of bugs, insects, rodents and their by-products. Introduce moisture, and you will likely have mold and other fungi growing as well. Some molds produce harmful vapors that fill the crawlspace. This is the air that is pulled up into the home causing health problems for many people.

Some homes in Knoxville have so much water in their crawlspaces that a drainage system is necessary to remove the water before a crawlspace encapsulation can be installed. Below is a list of some common causes of water entering and pooling in a crawlspace.

Common Causes of Water in a Crawlspace

  • Poor grading around the house. If the slope of the land does not move away from the house, rainwater likely will enter the crawlspace below the footer and gather in the crawlspace.
  • Improperly cleaned gutters. Believe it or not, gutters with too much debris cause rainwater to flow over the top and fall next to the house. This water often ends up under the house.
  • Downspouts improperly terminated. The downspouts on your home needs to be routed away from the home using a drainage pipe. If the downspout terminates at the foundation of the home and the water is not routed away, it will likely end up below the house.

Common Symptoms of Excess Moisture in a Crawlspace

  • Musty odors which are often a sign of mold
  • Sagging insulation or insulation dropping to the ground from the joists
  • Cupping, warped, or creaking floors inside the home
  • Microbial growth such as mold, mildew, fungus, and algae
  • Rotted or weakened floor joists and other wood decay

Installing a Dehumidifier in a Crawlspace: H2OUT Waterproofing

Installing a Dehumidifier in a Crawlspace

Using quality materials, H2OUT Waterproofing lines the floor and support beams of the crawlspace with five layers of protective barriers. Our competition suggests just using one.

The additional layers provide you with much needed protection to keep water, bugs, and other insects out of your home.

The walls of the crawlspace are covered with insulating materials that keep the home warmer in the winter, cooler in the summer, and dryer year round.

In addition, we always recommend installing a quality dehumidifier to control the relative humidity in the crawlspace. Moisture is an enemy of the crawlspace, and we must use every tool we can to keep it under control.
