How To Dry Out A Crawl Space After A Leak

A flooded crawl space is frustrating and inconvenient at best and can pose a health hazard at worst. While a bit of water in the crawl space after rain is normal, too much water is a huge hassle.   

Luckily, you can remove standing water from your crawl space with the right tools. Here’s how to remove water in your crawl space easily:

Tips on How to Dry Out Flooded Water in Crawl Space

Locate the leak

 The first thing you need to do to eliminate standing water in your crawl space is to locate the leak. Water can easily seep into your crawl space through small cracks or breaks in the walls. You can apply sealant or board up the leak to prevent further flooding.  

Use a pump to get rid of the water

 Using a pump is the easiest and fastest way to remove water from your crawl space. If you don’t have a pump at home, you can purchase or rent one from a construction store. 

Disinfect and deodorize the area from flooded water

 After removing all the groundwater in your crawl space, you should disinfect and deodorize the area. Flood waters contain harmful microorganisms, such as E. coli and leptospirosis, that can cause illnesses.

 Wipe down the surfaces inside your crawl space with a bleach and water solution. Afterward, use a dehumidifier to remove any lingering unpleasant odors.

Dry the crawl space completely to prevent the risk of mold

 Sprinkle baking soda on all the surfaces of your crawl space. You can also use fans to increase the airflow. After a few hours, vacuum your crawl space to remove the baking soda and the remaining moisture.

Repair any damages from flooded water in the crawl space

 When your crawl space is completely dry, inspect for any water damage. Throw away materials or belongings damaged by flood waters. Replace any damaged insulation as well. 

How Much Does It Cost to Dry Out a Crawl Space?

 Cleaning your crawl space can cost as little as $60. Renting a pump from Home Depot will cost around $50 per day, although you will need to put down a $100 refundable deposit. You can purchase other items, such as gloves, trash bags, and baking soda, for around $10. 

 However, if you opt for a professional crawl space cleaning company to remove standing water from your crawl space, it will cost anywhere from $1 to $3 per square foot. 

How to Prevent Water in Crawl Space?

 Preventing flooding in your crawl space is cheap, easy, and can save you many headaches. You can prevent water in your crawl space through these tips:

  • Installing a French drain – A French drain is a trench that diverts flood waters away from your crawl space.
  • Sealing entry points – Regularly check for holes or cracks in your crawl space to avoid water in your crawl space after heavy rains.
  • Install a sump pump – A sump pump automatically removes any excess water from your crawl space. 

What Are The Problems Caused By A Wet Crawl Space?

 Higher Energy Bills

 A flooded crawl space results in increased humidity in your home. This means that your HVAC utilizes more energy to regulate your home’s temperature, which shows up on your energy bill. 


 Moisture encourages mold growth, which can cause respiratory problems such as coughing, runny nose, and asthma. 

Dust Mites & Pests

Pests such as dust mites and rodents love moist spaces. Leaving water in your crawl space makes it suitable for these pests.
