Mike from Moldman assured me the discoloring was from minerals due to condensation getting in the room and that, by EPA standards, I could safely clean the area myself. He gave advice on the best way to clean the area and remove the staining. Very honest and knowledgeable. Would highly recommend them.

Removing Black Mold on Drywall and Wood

Black mold loves growing on drywall and wood.  These building materials are by far the most common areas of black mold growth.  The wood or drywall gets wet, a black mold spore that’s floating in the air lands on it, and it starts to grow within 24 hours.  Within a couple days you’ve got some visible growth, and within a week you’ve got colonies and an outbreak. It happens fast!

The good news is that the problem can easily be fixed by either a mold pro or a handy homeowner before any symptoms from black mold exposure appear.

Removing Black Mold on Drywall

Why black mold loves to grow on drywall and how to remove it.

Drywall is a wonderful building material.  It’s light, cheap, and easy. Throw up some drywall and you’ve got an “instant wall” in minutes.  Black mold loves growing on drywall because it is basically a giant food source. Made up of gypsum (a white, powdery mineral) encased in two layers of soft paper, black mold feeds on the paper as a food source.  

Also, drywall  soaks up water like a sponge, stays wet for long periods of time, and is difficult to properly dry out.  When drywall gets wet, mold usually grows on both sides of the drywall – the side you can see, and the backside that’s behind the wall that you can’t see.  Simply cleaning the mold off of the side you can see is not enough. You’ve got to get to both sides of the drywall.

Outside of a surface mold from humidity scenario, the best strategy for removing black mold from drywall is simply to cut out the impacted drywall and replace it with new. Don’t waste your time trying to clean it.  It’s best to (carefully) cut it out, bag it up, and throw it away.

How to kill mold in the bathroom and other humid areas.

There are some cases where you could simply spray moldy drywall with a mold stain remover.Clorox Clean Up is cheap and works well, but there are many others.  You can use mold stain remover when the black mold is simple “surface mold” caused by humidity. If you aren’t sure if it’s surface mold, or something more serious, get a virtual mold inspection

The most common example of this scenario is in a shower, along the wall or ceiling drywall.  When people take long, steamy showers, the shower walls & ceilings get wet with humidity and eventually black mold will start to grow.  You can lightly spray the walls with your mold stain remover, wait a couple minutes, and wipe it off. Repeat as needed. But keep in mind that unless you start drying out your bathroom after showering, the mold will eventually return.

Removing Black Mold on Wood

Removing black mold on wood is a bit trickier.  The wood behind drywall is part of the structural framing of the wall or ceiling, so it’s basically a permanent fixture.  Sometimes the wood is so rotted and falling apart that it needs to be removed and replaced with new. But that is rare, and in the vast majority of cases the wood is still strong and structurally sound.

The good news is that black mold on wood can almost always be easily removed.

Treatment for removing black mold from wood. 

To remove black mold on wood you can lightly spray the impacted wood with a mold stain remover, wait a few minutes, wipe it off with a scrub sponge, and repeat as needed.  The dark black mold stains will lighten up little by little. You may not be able to get the wood looking “like new” but the look will be greatly improved.  

Once you’ve got the wood looking pretty good, make sure the area dries out.  You can put up new insulation & drywall once you’re sure the underlying water issue that caused the black mold growth in the first place has been fixed.

In many cases, doing it yourself is the easiest option.

As you can see, removing black mold on drywall and wood is not very difficult.  It basically requires some elbow grease and a mold stain remover cleaning agent.  Check out our DIY Support page, featuring our eBook and virtual consultations, for more detailed steps on how to be successful with this.  This link also contains some important safety information and equipment you will want to use if you decide to remove it yourself. 

If you’re not comfortable doing it yourself, and you live near one of our locations in Chicago or St. Louis, you can contact us to get it done.  Either way, removing black mold on drywall and wood is nothing to be afraid of.
