Moisture Sources in a House

It is important to address moisture in your home as it can lead to a variety of problems, including mold growth, structural damage, and poor indoor air quality. However, before you can solve a moisture problem in your home, you must determine the source of the moisture. There are many possible sources of moisture in a house, including:

Internal Sources of Moisture

  • Cooking and bathing: Cooking and bathing can release a significant amount of moisture into the air.
  • House plants: Plants release moisture through transpiration, the process by which water evaporates from the leaves.
  • Clothes drying: Drying clothes indoors can add a lot of moisture to the air.
  • Unvented appliances: Unvented appliances, such as gas stoves and kerosene heaters, can release moisture and combustion byproducts into the air.
  • Fireplaces: Fireplaces can draw moisture out of the air.

External Sources of Moisture

  • Ground moisture: Moisture from the ground can seep into your home through the foundation, basement, or crawl space.
  • Roof leaks: A leaky roof can allow water to enter your home, which can lead to moisture problems.
  • Plumbing leaks: Plumbing leaks can also be a source of moisture in your home.
  • Condensation: Condensation occurs when warm, moist air comes into contact with a cold surface. This can happen on windows, walls, and other surfaces in your home.

What is a Moisture Test in a House?

A moisture test is a way to measure the amount of moisture in the air or in materials in your home. There are a variety of moisture tests available, including:

  • Relative humidity test: A relative humidity test measures the amount of moisture in the air.
  • Infrared camera: An infrared camera can detect moisture in materials by measuring the temperature of the surface.
  • Moisture meter: A moisture meter can measure the amount of moisture in materials by inserting probes into the material.

Moisture tests can help you to identify moisture problems in your home and determine the source of the moisture.
