For determining whether you have mold on your hands, there are some actions that you can take. First of all, examine your house for any indications of black mold, which are black, yellow or green areas and discolorations on the plagued areas. Likewise, if you have mold in your house, you must have the ability to spot a moldy smell, which can be rather strong sometimes. If your house has been flooded recently, or you have actually seen leaks, it is much better to look for these indications.
