Black mold removal kits can be found at many local stores, including pharmacies, home stores, or local supermarkets. Do-it-yourself mold kits can range anywhere from $30 to a couple hundred dollars depending on how big the area of mold is how extensively you want to get rid of it.
These kits usually work by using strips to test the air and surfaces in your home. The at-home remover kits should only be used if the infected area is less than 10 feet. Once the mold has gotten into insulation or wallboards, usually the only way to get rid of the mold is to remove the insulation or boards completely.
If the black mold problem in your home is fairly big, it can cost you thousands of dollars to call a professional in to eliminate the mold problem in your home. To remove mold from a small space such as a crawl space or small attic, it may cost you around anywhere from $500 to $4000 depending on how much mold there is.
For bigger areas such as a basement or if some walls need to be repaired, it can cost you around $7000 to get rid of the mold. If the area is really big and there is structural damage to walls and furniture, it can cost you anywhere from $10,000 to $30,000 for mold removal.
