Crawl Space Moisture 101 – Causes, Problems, and Fixes

Whether your damp crawl space moisture problem is a result of flooding from torrential rain, a broken or leaking pipe, or sewer backup, you want to address the issue immediately to avoid any major repairs.

Moisture problems in the crawl space of your Moberly, MO, home can pose a myriad of problems.

Failing to address your damp crawl space can lead to permanent foundation damage, rot, foul smell, and sagging floors.

Also, it creates a favorable breeding ground for mold, mildew, and vermin.

Ultimately, you will be left with a less-than-perfect home that’s going to adversely affect your family’s health.

Effects of Moisture on the Crawl Space

As the humidity in your crawl space rises, it contributes significantly to the amount of moisture in your space. Generally, when the humidity in your crawl space goes above 55%, it can foster a number of issues such as:

• Wood rot 
• Insulation damage 
• Mold and mildew growth  
• Pest and insect infestation 
• Muggy air 
• Structural damage 

If you notice any of these signs, contact your local crawl space repair contractor at FRS immediately. 

6 Steps to Stop Crawl Space Moisture Problems 

There are a number of things you can do to control crawl space moisture problems.

Here are the most effective ones.

1. Install Interior Drainage and a Sump Pump

It’s important to have properly functioning waterproofing solutions protecting your crawl space. An interior drainage system catches leaking water, and a reliable sump pump drains out floodwater that enters your crawl space, keeping it dry. If you already have one installed, inspect to ensure it is working correctly.

Crawl Space Encapsulation

Numerous studies show the best way to curb moisture is encapsulating the crawl space. Homes with crawl space seals tend to be notably drier and support less mold and mildew growth than their non-encapsulated counterparts. Your local basement contractor will cover the crawl space floor and walls with a heavy-duty plastic vapor barrier. Here’s how it helps:

• Minimizes mold and mildew growth 
• Minimizes vermin, insect and rodent invasions 
• Can save you up to 18% on your monthly energy bills 
• Dramatically improves your indoor air quality

Repair Foundation Cracks

Cracks, no matter how small, can introduce moisture or liquid water into your crawl space. So, check your foundation for cracks and ask your local basement contractor in Moberly, MO, to fix them. Don’t attempt a DIY if you don’t understand the root cause.

Fix Burst or Leaking Pipes

Old and worn-out pipes can sometimes fail. When a pipe in the crawl space bursts or leaks, it can release huge amounts of water into the crawl space. You will end up with high utility bills and structural damage. Ask your plumber to inspect and repair leaky pipes as soon as possible.

Dehumidify the Crawl Space

Sealing is a step in the right direction. But it won’t be able to dry out the air if it’s already moist. A better solution would be to install a dehumidifier. It will remove the existing moisture and ensure the crawl space remains dry.

Correct Drainage Issues

Your home’s downspouts and gutters are designed to channel excess water away from your foundation. Ensure your drainage system is intact, clog-free, and directing water away from your home.
