What is Moisture Mapping?
Moisture mapping is a professional service that involves the use of specialized equipment, such as thermal imaging cameras and moisture meters, to detect and measure moisture levels in buildings and other structures. This service can be used to identify areas of high moisture content, which may indicate the presence of leaks, water damage, or other issues that could compromise the integrity of the structure or create health hazards for occupants.
Acceptable Moisture Levels
The acceptable moisture level in a building varies depending on the materials used in construction and the intended use of the space. Generally, moisture levels should be kept below 60% relative humidity (RH) to prevent condensation and mold growth. The following table provides a general guideline for acceptable moisture levels in different areas of a building:
| Area | Acceptable Moisture Level |
|---|---|
| Living areas | 30-50% RH |
| Bathrooms and kitchens | 40-60% RH |
| Basements and crawl spaces | <50% RH |
| Attics | <40% RH |
It is important to note that these are just guidelines, and the actual acceptable moisture levels may vary depending on specific circumstances.
What is a Bad Moisture Reading?
A bad moisture reading is any reading that exceeds the acceptable moisture levels for a particular area of a building. High moisture levels can indicate the presence of water damage, leaks, or other issues that need to be addressed to prevent further damage or health risks.
- Moisture levels above 60% RH can lead to condensation and mold growth.
- Moisture levels above 70% RH can create a breeding ground for bacteria and other microorganisms.
- Moisture levels above 80% RH can cause structural damage, such as rotting of wood and corrosion of metal.
