Destructive floods are growing far too common in recent years. For example, Hurricane Florence dropped 18 trillion gallons of rain on North Carolina and its neighboring states.

The year prior, Hurricane Harvey dumped 27 trillion gallons of rain on the state of Texas. Unfortunately, the hurricane destroyed more than 30,000 homes.

Contrary to popular belief, the flooding that accompanies hurricanes is more dangerous than high winds. Floods not only put your life in peril but cause massive damage to your home as well.

If your community experienced flooding due to Hurricane Florence, you may be left wondering how to dry out a crawl space. Read on for a comprehensive guide on how to dry out a crawl space effectively.

This guide will serve you well in the event of a flood or burst pipe under your home.

Pump Out the Water

Before drying can commence, the first step is pumping out any water. There are commercial pumps available at most home improvement or retail store.

Depending on the magnitude of the flood, a commercial water pump may be insufficient. In this case, you will need to contact a professional company with a specialized, heavy-duty water pump.

How to Dry Out a Crawl Space

After you pump out as much water as possible, the next step is to start drying the crawl space out. This is an imperative step as leaving moisture in the crawl space can lead to mold and unhealthy living conditions. It can also negatively affect the integrity of your foundation, leaving the wood susceptible to dry rot.

You will need to either rent or purchase an industrial strength fan to help dry the remaining moisture. In severe cases, you may need multiple fans running throughout the day and night.

Power outlets are typically not available in the crawl space. This means that you will need to run multiple extension cords to the crawl space to operate the fans.

The positioning of the fans is important to make sure the crawl space dries out properly. Make sure that at least one of the fans is set up at the entrance of the crawl space.

This fan should be pointed towards the outside of the home, pushing the moist air out of the crawl space. Additional fans should be pointed directly at areas with water accumulation. Also, sheetrock and insulation should be dried out with a fan as well.

Next Steps

After the fans dry out any excess water in the crawl space, it is time for a few additional steps. First, make sure that your crawl space is properly ventilated.

This means there should be a sufficient number of vents allowing for cross ventilation. Another step is to install a vapor barrier in the crawl space to prevent moisture from rising.

Wrapping It Up

Flooding can decimate your crawl space and create unhealthy living conditions due to mold. If you have water in your crawl space, the time to act is now.
