The crawl space is an easy area to keep out of sight and out of mind, but a damp or flooded crawl space can cause a variety of problems for homeowners and should not be ignored.

Crawl space water damage can lead to structural problems, pest problems, and mold growth. While mold is always a serious problem that should be handled immediately, it is of particular concern if your HVAC system is located in your crawl space, as this will result in unhealthy air being circulated throughout your home.

Causes of Crawl Space Water

A variety of things can lead to the accumulation of pooled water in your crawl space. These include, but are not limited to:

  • A broken hot water heater
  • Ground water seeping through cracks or gaps in your foundation
  • Flooding from heavy rainfall
  • Sewer drain line leakage
  • Overwatering of plants and lawn
  • Landscaping that slopes toward the foundation of the house, rather than away
  • Incorrectly installer gutter downspouts, directing water towards the home’s foundation

As with other types of flooding, care should be taken to ensure safety, and scaled given the type of water you’re dealing with. In particular, water contaminated with sewage contains dangerous toxins, and should only be handled by a professional remediation company. Water that is clear and comes from clean sources, such as rainfall or a broken hot water heater, is not as likely to pose a significant danger to your health, but you should still exercise caution.

If you are cleaning up crawl space water on your own, be sure to wear protective gloves, boots, and a mask. If there is any chance of mold or asbestos, consult with your local hardware store to procure the appropriate mask for your situation.


Steps to Take

Identify Source

First thing’s first — identify and correct the source of the water. There is no sense in draining the water from you crawl space only to have it flood again within a matter of days or weeks. If you cannot determine the source, a water damage remediation company will be able to assess and address this situation.

Remedying the Current Situation

Depending on the amount of pooled water you’re dealing with, you will need either a wet vacuum or a sump pump to get rid of the standing water. Be careful using tools around any pooled water, as water and electricity are a very dangerous combination. Consult with an electrician there is water pooled around electrical outlets or wires, and never take any risks when it comes to this potentially dangerous situation. This is another instance where a remediation professional can help to assess the safety of the situation.

To remove moisture from the air, as well as moisture that has soaked into porous surfaces, utilize a dehumidifier. It is important to address even water that cannot be seen with the naked eye, as any remaining moisture will allow for mold growth.

Address Mold Growth

In particular, there may be mold in drywall, soil, and other porous surfaces. If soil has been infested by mold growth, that soil will need to be removed/replaced. The same goes for drywall.

You may be able to spot mold growth, or may smell a musty odor. Even if neither of these clear cues is present, if water has been sitting for a while, you would be best advised to contact a mold remediation company for a consultation. The last thing you want is for mold to make its way through your vents and impact your entire home.
