HouseMaster has been in the home and business inspection industry for more than 3 decades, inspecting over 2 million homes across the United States. We are one of the most trusted names in home inspections, providing our customers with the highest quality.

"The team did an excellent job. Two walls were removed and they cleaned and treated inside the walls. They also pulled up my carpet which was a great help, as I was worried about spores being in there after the work. They sealed off each area with plastic to contain it and used the appropriate safety equipment. It is difficult to find mold specialists who really know what they are doing. They were transparent and informative about the job, which made me feel confident moving forward with them. The work performed was very thorough and they kept me updated throughout the process with pictures. Everyone I met/talked to from Stay Dry was very professional and polite. It is apparent that they care about the quality of their work and their customer service. That matters to me because I need to feel safe and healthy in my home. I will hire them for the next job."

Mold Testing and Remediation questions, answered by experts

It is not advisable to stay in a house with black mold. Exposure to black mold, or any mold, can lead to health problems, especially for vulnerable individuals such as children, the elderly, or those with weakened immune systems. Black mold produces mycotoxins, which can cause respiratory issues, skin irritation, fatigue, and headaches. If black mold is detected, it is crucial to evacuate the premises, seek professional help for remediation, and only return once the area is thoroughly cleaned and confirmed mold-free by experts.

Frequently, fungi have a gray color with a powdery or fuzzy texture on a wall. In showers, fungi and mildew may resemble a pink slime. Meanwhile, toxic mold may resemble a fuzzy growth on walls that’s often black or green in color. Some toxic black mold will have specks of orange or white on it. However, not all dark-colored mold you find on a wall is toxic. An infestation of toxic mold often will spread faster than fungi on walls. If you are unsure whether you have toxic mold, reach out to a professional for help.

The duration of mildew smell in carpets depends on several factors, including the extent of moisture, cleanliness, and ventilation. If promptly addressed, the smell can diminish within a few days to a couple of weeks after thoroughly drying and cleaning the carpet. However, in severe cases or if not properly treated, the smell might persist. Persistent odors could indicate deeper mildew growth, requiring professional cleaning or, in extreme cases, carpet replacement to completely eliminate the smell.

Yes, by identifying allergens and implementing measures to mitigate exposure.

After you clean mildew or mold that appears in your home, you expect the nasty odor to disappear, too. Sometimes, though, the odor can linger after cleaning. To get rid of a mold smell, you may need to clean the area every few days for a few weeks. Use a dehumidifier or fans to try to remove moisture from the area. If the odor remains after a few weeks, you may still have mold or mildew in the area. Call a mold testing professional for another inspection.
