Who would want a house that has BLACK MOLD ?
In reality, most mold infestations CAN be remediated as long as there isn’t so much structural damage that the basic structure is shot. Mold is a simple organism which needs 3 elements to grow…food (the wood), temperature, and moisture. You cannot control the first two but you CAN control the third. Get rid of the moisture and it won’t come back once remediated. Plus there are now preventative coatings we apply which prevent growth from re-occuring. If the house is otherwise nice and the cause can be prevented, get some quotes from a mold remediation professional to take care of the problem and put an offer in based on those costs.
