No home or business owner wants to find out that they have mold in their property. Not only is it unsightly, but the presence of mold can also lead to health issues. If you are experiencing air quality issues such as mold or odors, Green Home Solutions of Central Savannah River Area provides a wide range of services to create a clean and healthy indoor air environment. Mold inside your property isn’t just an eyesore and a source of odor, but it can also have a wide array of negative effects on the health of the structure’s occupants. By the time you or the other people inside your home or business begin to notice signs of a mold infestation, it is likely that the problem has spread throughout your property. In addition to all of the impacts of mold mentioned above, it can also significantly reduce the value of your property. Mold cannot just be scrubbed away, but must be treated by professionals to ensure that it is not only removed, but that it doesn’t return.

Mold Testing and Remediation questions, answered by experts

Unfortunately, mold can grow pretty much anywhere, on any kind of surface. However, you’re most likely to see it in damp areas like basements or bathrooms, as well as anywhere there has been a water leak. Consult a local mold specialist to determine if certain areas of your home are prone to mold based on climate and other factors.

The purpose of crawl space encapsulation is to prevent mold and moisture from entering your space. If your vapor barrier is properly installed and intact, it will dramatically reduce the chance that your crawl space develops mold. That said, moisture can condense in the area. If you notice excess humidity, you may need to install a dehumidifier to stave off mold and mildew growth.

Once again, contact with moisture is the culprit here, though water-resistant varieties of wallpaper are less likely to become wet and develop mold. Using a high-quality exhaust fan or dehumidifier and leaving the doors or windows cracked after bathing will keep this issue at bay. 

Mold grows quickly. It typically begins to grow on drywall about 24 hours after exposure to moisture or humidity. Drywall is a porous material, which makes it particularly hospitable to mold growth. 

While mold growth begins after just a day or so, it can take a few weeks before the evidence becomes visible. Mold spores will typically appear on the drywall surface within three weeks of growth starting.

Yes. Black stains are more than an eyesore. Some black stains can pose health concerns, especially for those with asthma, allergies, or other respiratory conditions. Some stains can also damage the brick’s structural integrity, harming the mortar and resulting in more expensive repairs.
