Moisture Sources from Outside

Moisture problems in a house can originate from outside sources. These sources can be difficult to identify, but it is important to address them promptly to prevent damage to your home. Common sources of moisture from outside include:

  • Groundwater: Groundwater is water that is found beneath the surface of the earth. It can seep into your home through cracks in the foundation or basement walls. If the groundwater level is high, it can also cause flooding.
  • Surface water: Surface water includes rain, snow, and runoff. It can enter your home through windows, doors, or cracks in the walls. If your home is not properly graded, surface water can also pool around the foundation and seep into the basement.
  • Condensation: Condensation occurs when warm, moist air comes into contact with a cold surface. This can happen on walls, windows, and pipes. Condensation can lead to mold growth and other moisture problems.
  • Capillary action: Capillary action is the ability of water to move through small spaces. This can happen through the pores in concrete or brick. Capillary action can draw water from the ground up into your home.

**What is a moisture test in a house?**

A moisture test in a house is a procedure used to measure the amount of moisture in the air or in building materials. This can be done using a variety of methods, including:

  • Relative humidity sensors: These sensors measure the amount of water vapor in the air.
  • Moisture meters: These meters measure the moisture content of building materials.
  • Infrared cameras: These cameras can detect areas of moisture by measuring the temperature of surfaces.

Moisture tests can be used to identify sources of moisture problems and to assess the extent of damage. They can also be used to monitor moisture levels over time and to evaluate the effectiveness of moisture control measures.
