"They did a very good job of remediation as far as I can tell, but David wasn't quite truthful about two things he told me. They also put my stuff back in the basement onto the floor while it was still wet from remediating. That didn't sit right with me."

"Mr. Frank Trust and his employee, Toby, were prompt, extremely thorough, polite, professional and so considerate. Due to a leaking garage roof, mold and mildew developed and much of the stored items were destroyed. Mr. Trust and Toby spent about 7 hours cleaning, decontaminating and power washing the structure. They even cleaned, sanitized, wrapped and packed the personal items that could be saved. They did a fantastic job. Mr. Trust is a genuinely kind man. I’ve already recommended him to a friend. Thank you so very much for the service."

Mold Testing and Remediation FAQs, answered by experts

In most cases, it's not worth the risk of buying a home with mold. You should carefully weigh the pros and cons before making a decision—and there are far more drawbacks than benefits. For one, buying a house with mold opens you up to health risks since mold can cause respiratory and allergic reactions. If the mold is widespread throughout the home, the cost to completely remove it, make necessary repairs, and prevent it from returning is often not worth the cost savings of buying a mold-infested home for a bargain.

Usually, when you have mold, you will notice that your indoor air quality isn’t what it should be. You might notice dank odors, for instance, coming from your carpet, and it may feel damp or spongy. Or you may find that your family members are showing more allergy symptoms than usual, from coughing and sneezing to itchy, watery eyes.

And, of course, if you’ve recently experienced flooding or you live in a particularly humid environment, that’s a good sign you’re at risk for mold growth.

A funky smell is the first indicator that mold or mildew is present in your home. You may also notice that you or your household members are suffering from increased allergies or respiratory issues. You should check the most obvious areas first—like your bathroom or anywhere there might be leaks—and if you still can’t locate the source, look under the floorboards. 

Bathroom mold tends to reappear due to the persistent presence of moisture and humidity, creating the ideal conditions for its growth. Since bathrooms are inherently humid environments, without proper ventilation, moisture accumulates on surfaces, providing a continuous food source for mold spores. Mold spores are present in the air and settle on damp surfaces to start growing rapidly. Additionally, if the underlying causes of mold, such as plumbing leaks or inadequate sealing, are not addressed, mold will return even after removal. To avoid recurring issues, addressing the root cause by improving ventilation, fixing leaks, and maintaining a dry bathroom environment through regular cleaning and maintenance is essential.

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.
