First, was the moisture intrusion source(s) corrected? If moisture is under control, a Clearance Test should be performed which is a combination of factors that include a visual inspection, review of remediation protocol, sampling, etc. Only then can you get a good idea if the area was properly brought back to normal fungal ecology.
Very! Moisture drives all biological processes in a built environment and the way moisture moves through a home can help explain what is going on. Take older / historic homes, the moisture issues can be very complex.
Not as much as you think. Depending on the scope of work and if demolition is involved it can be affordable if you catch the issue early enough. But long going prolonged moisture issues almost always cost more than you would think.
Mold is a product of hydrology, humidity and moisture. Was the source of water that caused the mold addressed as part of your remediation? We know that mold and water go hand in hand. If your environment’s hydrology are not properly managed, the mold will return. We have Certified Hydrologists on staff to ensure that the source of water is appropriately addressed to ensure any future mold growth is mitigated.
Many times moisture makes its way into the wall cavity and stimulates molds to grow. Given time they will start to “Bleed Through” the outside wall and at first look like a small dark area. If the moisture source is not obvious, further investigation by a pro is recommended.
Cleaning mold often does not address what is causing the mold to grow in the first place. And that’s what we call the “Moisture Trigger”. While we often think of moisture as a “puddle”, in this case, molds don’t like puddles, they like elevated humidity which is hard to detect on your own. Better call a mold pro.
