Why Is My Home Always Humid?

If you’re dealing with high humidity in your home, you probably want to fix the problem right away, as high humidity levels make for an extremely uncomfortable living environment. But discomfort isn’t the only thing you have to worry about—high indoor humidity can also cause problems like mold in your home, which can make your family sick.  

Before you can solve your home’s humidity problem, however, you need to find out what’s causing it.

What Causes Indoor Humidity? 

Some of the most common causes of high indoor humidity levels in a home include: 

Air Leaks 

Very few homes are truly air-tight. Most are full of small gaps and cracks called air leaks, which allow moisture-heavy outside air to flow freely into your home, raising indoor humidity levels. Air leaks are frequently found in your attic, which is why attic humidity levels tend to be so high. 

Ineffective Insulation 

If your home is full of air leaks, the moisture-heavy air coming in will damage your insulation by getting it wet. This can render your insulation ineffective, increase moisture and humidity levels in your home, and cause mold to grow. 

Basement Moisture Intrusion 

Foundation cracks, grading problems, and basement air leaks can all cause excess moisture to collect inside your basement and raise humidity levels throughout your home. Solving wet basement and crawlspace issues can be a highly effective way to reduce humidity.

Occupant Habits 

Certain habits like taking long, hot showers and forgetting to turn on the kitchen fan while cooking can cause humidity levels to rise in your home. 

How to Get Rid of Humidity 

There are a few different ways to address high indoor humidity, including: 

1. Air sealing – Sealing up air leaks will stop humid outside air from entering your home.

2. Insulation upgrades – Replacing wet, damaged basement and attic insulation can help improve humidity and mold problems. 

3. Basement and crawlspace waterproofingBasement and crawlspace insulation, vapor barriers, sump pumps, and other waterproofing solutions can all help control indoor moisture. 

4. Dehumidifiers – Installing a dehumidifier will actively reduce excess humidity. 

5. Lifestyle changes – Making minor lifestyle changes, like taking cooler showers, can help keep indoor humidity levels low.
