What To Do About High Crawl Space Humidity

When the barometer or hygrometer rises, but there is no flooding in your crawl space, high humidity can still cause damage. Here’s what to do.

Schedule Free Inspection

Richmond, VA, has to deal with plenty of ocean-based humidity on a yearly basis. Rising humidity outside of your home is one thing, though. Rising humidity inside your home is another beast entirely. As your barometer or hygrometer ticks upward, you can start to endure more than unexpected discomfort in your home. High levels of humidity in your crawl space, in particular, can lead to significant damage both in that space and throughout the rest of your home.

The good news is that you can take steps to control the degree of humidity in your crawl space—and the rest of your home—has to deal with. You can reach out to area professionals at any time to schedule a crawl space inspection or discuss the other reasons you may be enduring an unusual amount of internal humidity in your home.

Should You Worry About High Crawl Space Humidity?

High levels of humidity in your home are more than just uncomfortable. They can also be a sign of structural damage in your crawl space. Similarly, humidity causes a litany of problems on its own. Some of the most common dangers affiliated with high levels of crawl space humidity include but are not limited to: 

  • Mold and wood rot 
  • Leaking concrete  
  • Bowing walls 
  • Infestations 
  • Damaged crawl space supports 
  • Sagging door and window frames 
  • Cracking concrete 
  • A sinking foundation or slab

Where Does Unwanted Humidity Come From?

The humidity in your crawl space can start to rise for several reasons. The most common include:

Leaking Pipes

Hydrostatic pressure doesn’t just build up outside of your home. If the pipes in your crawl space start to leak, you may find yourself contending with internal hydrostatic pressure—which can allow moisture inside more easily. 

Leaking pipes add moisture to the air in your crawl space on their own, too. If you don’t take care of a leak quickly, that moisture can build up in your crawl space to the point where you start to see mold, wood rot, and other types of damage. 

Hydrostatic Pressure

As water builds up outside of your crawl space, the materials used to set the space apart from the rest of your home come under what is known as hydrostatic pressure. This force causes your structural supports to change in size and temperature on a structural level. While these changes are not a bad thing when they occur infrequently, they’re often too much for your supports to bear en masse. If your concrete or wooden supports start to show signs of wear, moisture can wriggle its way into your crawl space, where it can cause all sorts of damage while further disrupting the structural integrity of your home’s essential structures.  

Dealing With High Crawl Space Humidity

The repair professionals in Richmond, VA, can recommend several different methods for you to use if you want to lower the humidity in your crawl space. Some of these involve repairing invisible damage that’s been done to your home. Others involve waterproofing your space before the incoming moisture can build on itself. 

Some of the most common means of crawl space protection and repair in the face of high humidity include: 

You do not want to install crawl space waterproofing measures without first repairing any damage that’s already been done to your crawl space. If you try to install any of the aforementioned measures without investing in crawl space repairs, those waterproofing measures will fail much more quickly than they would have otherwise.

The good news is that high levels of humidity without puddles on the ground tend to indicate minor damage throughout your crawl space. You can work with an area professional to assess the overall damage in your home and then arrange for any necessary repairs.
