Measuring Dampness Levels

Dampness is a common issue in buildings, and it can have a negative impact on the health of occupants.

Excessive dampness can cause a variety of health problems, including respiratory problems, allergies, and asthma. It can also damage the structure of a building, leading to costly repairs.

To prevent these problems, it is important to measure dampness levels and take steps to control them. Measuring dampness levels is a relatively simple process that can be done using a variety of methods.

What is an acceptable damp reading?

An acceptable damp reading is typically considered to be below 20% relative humidity (RH). Relative humidity is a measure of the amount of water vapor in the air compared to the amount of water vapor that the air can hold at a given temperature.

Dampness levels above 20% RH can start to cause problems, such as condensation on surfaces, mold growth, and dust mites. These problems can lead to health issues, such as respiratory problems, allergies, and asthma.

If you are concerned about dampness levels in your home, you should contact a professional for advice. A professional can measure dampness levels and recommend steps to control them.
