RH is the Supernatural Measure of Moisture

Relative humidity (RH) is considered the most crucial measure of moisture when assessing potential water damage risks and seeking solutions. RH levels indicate the amount of water vapor present in the air relative to its capacity at a specific temperature and air pressure.

Understanding RH Levels

• Low RH (below 40%): Dry air, less likely to cause condensation or mold growth.
• Moderate RH (40%-60%): Comfortable for humans, unlikely to support mold growth.
• High RH (above 60%): Contains more moisture, increasing the risk of condensation and mold growth.

RH and Water Damage

High RH levels contribute significantly to water damage: when warm, moisture-laden air comes into contact with cooler surfaces, condensation occurs. This moisture can penetrate building materials, leading to rot, mold growth, and structural damage.

Controlling RH Levels

Managing RH levels is crucial for preventing water damage. This can be achieved through:

• Ventilation: Allowing fresh air to circulate
• Dehumidification: Removing moisture from the air using a dehumidifier
• Moisture control barriers: Preventing moisture from entering a building

Professional Expertise

Understanding RH and its impact on water damage requires expert knowledge. Professional moisture inspectors and restoration specialists possess the expertise to:

• Assess RH levels
• Identify sources of moisture
• Recommend solutions to control RH
• Prevent and mitigate water damage
