"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

Some causes of brown well water—like excess tannins or dissolved iron—don’t pose a health risk. In other cases, harmful bacteria might be the culprit. If your well water has suddenly turned brown, it’s a good idea to use a home water test kit to get a better sense of what’s going on with your water. Consider calling a professional for an expert opinion before drinking the water and hoping for the best.

Black mold appears in areas with constant moisture and has a slightly fuzzy texture. It’ll have a primarily circular pattern. While it’s known to have a black color, it can also appear dark green, or dark brown, although a few types include orange or white flecks. Identifying black mold is important because people who inhale the spores could suffer respiratory issues or neurological problems. Black mold is a toxic material and requires a professional to remove it.

Mold thrives in high-moisture environments, whether that’s steady leaks or just high condensation. Around the house, common causes of mold include leaky pipes, a leaking roof, high humidity, poor ventilation, a damp basement, rotting food in the fridge, wet clothing and towels not hung properly for drying, a leaking foundation, and a leaky air conditioner.

And, of course, if your home suffers from flood damage, you stand the risk of developing mold in the aftermath. That’s why it’s important to act quickly at the first sign of mold.

Yes, mold on wood furniture can be dangerous, especially if it is identified as black mold. Inhaling spores or touching mold can make some people sick with respiratory issues, skin rashes, and eye irritation. However, some people have mild or no symptoms after exposure to mold. If you are going to clean mold off wood furniture, you should wear protective equipment to avoid direct exposure.

If you find black residue in your toilet tank, chances are it’s caused by manganese deposits from hard water and not mold growth. You can prevent these deposits from damaging your toilet by installing a water softener in your home, which also might improve the quality of your drinking water. You can also remove the deposits inside your toilet tank once every six months or so to prevent them from causing problems with toilet functionality.
