Black Mold: The Aftermath of a Flood

Given that the only things mold needs to survive are moisture and a food source, it’s easy to see why mold is such a common problem after a flood.

In fact, if you don’t dry the flooded area thoroughly within 24 to 48 hours, mold will start to form, feeding off of carpets, drywall, fabrics and wood – all of which are frequently found in basements, bathrooms and other rooms that are prone to flooding.

Flooding can lead to water-damaged carpets, which are a hot spot for black mold.


Some species of mold (like Aspergillus, Penicillium, Chaetomium and Stachybotrys) are known to produce toxic chemicals and emit them into the air, causing a wide range of health problems.

These molds love moisture and are typically found indoors after a flood.

How to prevent black mold after a flood

Acting fast is most important when reacting to a flood. Get the water out as quickly as possible, remove water-damaged materials and dry the area completely.

To do this, use everything you’ve got: turn on all dehumidifiers, fans and ventilation units. You also want to ensure sufficient air circulation and air exchange throughout your house.

As with all demolition/renovation work, it’s important to take proper safety precautions. Be aware that sewage is common in floodwater and remember to turn off all electricity in the area.

With all of that said, for major flooding, it might be a good idea to contact a flood restoration specialist because some damage may not even be visible to the naked eye.

If possible, you should even consider contacting a professional mold inspector to assess your property for mold growth. Catching the mold problem early on could save you a lot of hassle and money down the road.

At Mold Busters, we know that one of the best ways to test for mold is to take an air quality test in the affected area. This test will let you know if you have any mold problems and, if so, which species of mold you’re dealing with.

From there, our experts can help guide you through the remediation process every step of the way. Contact us if you’d like to learn more about flood restoration and mold removal.
