Larger Drywall Test Cuts To Check For Hidden Mold Contamination
Where we have justification to proceed we may cut a 2″ x 3″ hole in drywall to peer into a wall cavity.
This opening, like the plug cut openings discussed above, is trivial to patch in drywall or plaster, but permits a more reliable inspection of the building cavity interior than a borescope.
Where damage is already extensive, there is nothing lost, no material to preserve, and a still larger opening may be cut, or multiple openings, in order to confirm the extent of contamination and thus the extent of demolition and mold cleanup needed.
Memnoniella echinata – a toxic black mold in a wall cavity: During an investigation of a high-rise apartment in a large U.S. city, I was asked to evaluateblack mold visible on basement floor joists in a kitchen.
Our mold inspection procedure includes a screen of the entire living unit which in this case was a large multi-room apartment.
At the far end of the apartment, remote from the kitchen and its leaks and mold, I found evidence of other leaks into and below an expensive cherry-wood floor.
We traced leaks to an air conditioning wall unit whose condensate was draining into the floor ratherthan into its drain.
The photo above shows our initial test cut into the wall cavity.
The next photo below shows a closeup of the cavity interior.
We chose an area to make a “test cut” into the wall cavity where we thought there had been the most water exposure.
Another “toxic black mold”, Memnoniella echinata is particularly toxic and irritating.

How To Detect Mold
Mold is a type of fungus that grows almost everywhere, as long as the environment is damp and has temperatures between 40 °F and 100 °F. If you are going to be honest with yourself, that’s almost all damp areas in your house. While these tiny microorganisms might be useful outdoors, they can cause serious health issues in your house. Some of them are known to produce dangerous toxic chemicals called mycotoxins. Some others also produce allergens that are known to cause allergic reactions. Beyond medical problems, molds can also cause extensive property damage. When they appear on a surface, they gradually fester on the surface, leaving it to rot.
The most common types of molds called mildew are easy to spot. At the very early stages, they often start as dark spots that later grow into large colonies. It’s the dark things that you see on the damp walls in the bathroom, the grout lines in the shower, on deck boards and many other shaded areas. The mold you can see are usually not a problem because depending on their size, you can easily remove them. However, some molds grow in areas where you can hardly see them. Even when you see some, you might confuse them with dirt. In such a situation, mold detection becomes the most reliable way to help you detect the problem and find the mold.
Perform A Visual Inspection
If you suspect you have mold, the first step is to perform a thorough visual inspection of your home. You will recognize mold as spots that can appear in many different colors.

A common myth is that it can only grow on certain materials. Spores can spread on fabric, glass, paper, wood, and plastic in your home. They can even start to digest the material that they grow on.
Each mold type has preferences for where they like to grow:
- Aspergillus tends to grow on powdery substances. This includes food, dust, and drywall.
- Alternaria shows up where its damp. This could be a leak, a shower or bath, or under the sink.
- Cladosporium ends up on fabric and wood in cool or warm climates.
- Penicillium shows up in water damage with a blueish greenish hue.
Fungi like this can be of various colors, textures, and forms, so dont rule something out as safe just because it doesnt look like what youre used to.
Know How to Spot It
Its important to realize that mold is not always visible. This fungus can be detectable by smell, and symptoms, as well as appearance. It can smell musty and stale and cause respiratory symptoms and flare-ups like triggering asthma attacks. Sometimes, these symptoms may be the first sign to you that you could have mold.
