"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

Painting over mold is not an effective solution and can actually make the problem worse. Instead, it traps moisture, which allows mold to grow and spread beneath the surface. Mold must be completely removed before painting to ensure the problem doesn’t recur. If mold is painted over, it may eventually seep through the new layer of paint, causing discoloration and peeling.

Damp air from a humidifier can cause mold in ducts if it raises the air's humidity level too high for the duct system to handle or malfunctions, but it’s not a normal occurrence. To avoid mold trouble, set the humidistat to between 30% and 35% and inspect it often to ensure accuracy.

Although fiberglass dust is generally not considered toxic, inhaling excessive amounts of it can lead to health risks. Irritation to the respiratory system, eyes, and skin are common effects of fiberglass particle inhalation. While short-term exposure to the dust may only cause temporary discomfort, long-term or chronic exposure can lead to more severe respiratory problems.

Proper safety measures, such as wearing appropriate protective equipment, including masks and goggles, should be observed when handling or working with fiberglass materials to minimize health risks. It is important to note that, unlike asbestos, fiberglass is not associated with life-threatening illnesses.

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.

It is not advisable to shower in a bathroom contaminated with black mold due to the potential health hazards it poses. Inhaling mold spores during showering can trigger allergic reactions, respiratory issues, and skin irritations, especially for individuals with pre-existing allergies or respiratory conditions. Prolonged exposure to black mold can result in severe health complications. It is crucial to eliminate any black mold problems in your bathroom before continuing with showering to ensure a safe and healthy environment.
