Is Mushroom Mold Dangerous
Mushroom mold is dangerous to both humans and animals and could cause many health issues. One of the leading health issues that mold mushrooms could cause is respiratory problems, ranging from a simple cough, wheezing, tightness in the chest, shortness of breath, or asthma-related symptoms.
For people who already have a compromised respiratory function, such as those with cystic fibrosis or a chronic obstructive pulmonary disease, mold could cause much more severe symptoms, for example pneumonia-like inflammation of the lungs.
You should keep your animals and children away from the basement until the mold and mushrooms have been adequately removed.
It should go without saying, but never eat a mushroom that you find growing in your home. This goes for mushrooms growing outdoors in the wild as well.

Yes, the sheet rock should be removed. This is necessary not only to clean up the existing mold, but to implement the prevention measures.
First, you need to identify the source of the moisture. Three possibilities exist. 1.) Condensation from the warm interior air hitting the cold concrete wall. This typically does not happen behind a well sealed wall , but its possible.
2.) Vapor emissions through the concrete. This occurs when moisture moves through the concrete in vapor form, creating high humidity and saturation on the surface. In an uncovered wall, the water would simply evaporate into the air without causing an issue. The installation of the sheet rock traps the moisture, leading to mold growth. There are two solutions either keep the concrete exposed or install dimple board with a interior footing drain.
3.) Liquid water intrusion. Its possible youre having liquid water enter through the cold joint at the bottom of the wall. If this is the case, youll see more damage at the bottom plate/framing than higher up the studs. In most cases, the solution is an interior footing drain.

How Much Does Black Mold Removal Cost
To properly remediate mold , you’ll need to hire a mold remediation specialist. A mold remediation specialist will remediate the basement while making sure mold spores do not get into the heating and cooling system, which would otherwise get recirculated throughout the home, continuing to make occupants sick even once the basement itself has been cleaned.
So what does black mold removal cost? It’s not quite a cut-and-dry answer. The level of infestation directly affects the black mold removal cost. The black mold removal cost of an unfinished basement can really vary. It could be as little as $500 or as high as $4,000 depending on the scope and size – AKA how much mold is present and how much area it covers. If the attic and ducts are involved, the cost for those generally ranges from $2,000 to $6,000. If the home has recently been flooded and the mold is all throughout it, there is much more that has to be done. This could drive a remediation cost up to $10,000 – $30,000, or higher, depending on the size of the home.
Even though you have an idea of how much mold removal costs, be sure to shop around. The first company you find might not be the best one for your needs. Pricing can vary between companies, but you also have to pay attention to the experience levels and what kind of guarantee they have if the mold comes back.

White growth on concrete is nearly always efflorescence, not mold growth. You can verify this by spraying a bit of water on the suspected growth. If its efflorescence, it will disappear as the crystals are dissolved by the water. If its mold, it will flatten, but remain visible.
I recommend removing the rubber mats for now. The impervious nature of the mats will prevent the concrete from releasing the moisture. After a week or so, put a couple of mats back down. Peel them back a few days later and look for signs of moisture on the underside of the rubber. If you see moisture, pull them off and allow the concrete more time to dry.

Fix Any Fixtures Damaged By Mold
With that said, there are some occasions where you might be able to save and restore items affected by mold. Some items that are considered to be prime restoration options include:
- Furniture. Wooden furniture can be restored if you are willing to sand away the portion eaten away by mold. You will need wood filler and a wood stain, but its still possible.
- Ceramic. Soaking ceramic in white vinegar will remove the mold and the stains.
- Plastic. Most plastics will be easy to wipe down. Just make sure its not porous!
- Sheetrock/Walls. If you have mold-damaged walls, you will need to call professional mold remediation crews to fix this. Either way, you will need to address this to prevent mold from re-entering your room.
Note: You still need to remove the restorable items from the room and treat them to continue your clean-up. When theyre mold-free, you can re-introduce them to the room.
