Mold Testing and Remediation questions, answered by experts

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.

The answer to whether it’s safe to use a moldy dishwasher is: It depends. Mold exposure affects people differently. It’s possible that even a small amount of mold in your dishwasher could contribute to respiratory issues and other health problems, especially if you have an underlying health condition. Mold is capable of surviving the high heat and detergent used in a dishwasher cycle, so it’s important to ensure that you act quickly at the first sign of mold, or contact a house cleaner near you to stay on top of any potential mold problems.

Many types of mold spores and fungi spores are constantly present in the air, but they need a friendly surface and moisture to grow. Should some of these spores land on paper or wood with significant moisture present—such as drywall with a paper cover that is soaking up water from a leak—mold or fungi could begin growing. Dampness from leaky pipes, condensation on windows, leaks in a roof, flooding in a basement, or high, prolonged humidity in a small area all can create the excess moisture that mold and fungi need to grow in your home.

Yes. Over time, hidden moisture from a leak in your bathroom may lead to black mold, requiring a mold remediation company’s services and the removal of large wall sections, which can be costly. For example, 100 square feet of drywall can cost as much as $400 to replace, while mold remediation can run anywhere from $500 to $3,000.

The gasket and drum of a washing machine are ideal spots for mold to grow. They are dark, warm, and humid, conditions that mold thrives in. The products you use to wash your clothing, such as fabric softener and detergent, can also encourage growth by giving the mold a food source.
