Mold Testing and Remediation FAQs, answered by experts

No—there are key things that help you determine if it’s mold versus mildew. Mildew is a specific type of mold. Both can trigger allergies, asthma, and respiratory symptoms, though mold is typically more severe than mildew.

Mold can greatly impact your home's appraisal and lower your selling price if your home's on the market. Home appraisers take mold into account when figuring out a property's overall value. Mold will lower your home's price because it poses a health risk to household members and can compromise the structural integrity of the house. Mold will require remediation, which in extreme cases can be costly, so that is factored into your home's appraisal as well.

Both mildew and mold come from fungi. One of the main differences is that mildew’s texture is dry and powdery, whereas mold is fuzzy and slimy. In addition, mildew isn’t very thick, while mold looks three-dimensional. Also, mildew is typically light in color, whereas mold comes in various shades, including green and black.

It depends on the type of AC unit and the extent of the mold growth. For example, if you have a small amount of mold in your central air conditioner, it’s worth cleaning it to protect your HVAC system and your health. In situations like these, you can often remove the mold yourself in a couple of hours. On the other hand, if you have a portable AC unit with a severe mold problem, it makes more sense to buy a new one. On average, replacing a portable AC unit costs $100 to $500.

While the resistance of lime to mold is a hotly contested topic of debate, it is true that because it allows porous materials to breathe, it avoids trapping moisture close to the structure of a building. This breathability makes it less susceptible to mold than paint because it gathers less moisture.
