basement humidity level

Introduction

It is expected that moisture is the best friend of mildew and mold. Therefore it should also be taken into consideration when building or remodeling a basement, attic, or garage, even if there’s no sign of visible water leaks. A humidity level that fluctuates between 40 to 60 percent can cause severe damage to your property and health risk for you and your family. That’s why you have to maintain the ideal environment to avoid these unpleasant consequences. This article will provide helpful information about basement humidity levels with further information.

What is humidity?      

Humidity is a measure of water vapor in the air. The higher the humidity, the more water vapor is present in the air. To measure humidity accurately, both temperature and humidity must be considered.

Types of Humidity

  • Absolute Humidity: The weight of water vapor in a given volume of air.
  • Relative Humidity: The percentage of moisture in the air compared to the maximum amount of moisture that the air could hold at that temperature.
  • Specific Humidity: The weight of water vapor per unit weight of dry air. 
  • Dew Point Temperature: The temperature at which absolute humidity reaches its maximum.
  • Vapor Pressure: The pressure of water vapor in the air. 

Basement Humidity Level

The humidity level in basements is usually higher than in other parts of the house because it is more relaxed and darker. Basements are perfect for mildew, mold, and dust mites to grow. Dust mites are tiny creatures that thrive in high humidity levels. They can cause asthma and other respiratory problems.

What is the ideal basement humidity level?

The ideal humidity level for a basement is between 30 and 50 percent. This will help prevent mildew, mold, and dust mites from growing.

Causes of excess humidity in basements

Improper Ventilation

If the basement is not properly ventilated, moisture will build up and cause the humidity level to rise.

Leaks in Water Pipes or Sewer Lines

Leaks in water pipes or sewer lines can cause excess moisture and increase the humidity level in the basement.

Condensation on Cool Surfaces

Condensation on cold surfaces such as walls, ceilings, or floors can cause excess moisture and increase humidity.

Flooding

Flooding can cause severe damage to property and increase the humidity level in the basement.

What are the effects of basement humidity issues?

1. Damaged Material

3. Dust Mites

Dust mites thrive in high humidity levels and cause asthma and other respiratory problems.

4. Uncomfortable Conditions

High humidity levels can make the basement uncomfortable because it feels damp and sweaty.

5. Increased Energy Costs

6. Basement Flooding

Basement flooding can be a severe problem and cause extensive property damage.

The air quality in your house is affected by the amount of moisture and the source of moisture, so maintaining proper ventilation will help reduce excess humidity to a certain extent. 

Get rid of standing water

Standing water increases the humidity level in the basement, which causes mold and mildew growth. Therefore it’s necessary to get rid of standing water as soon as possible.
