Mold removal is a scary thing to contemplate for many people, and often its success or failure determines the outcome of a real estate transaction. Some fear that mold removal is not possible in an absolute or permanent sense and that once established it will always come back like a monstrous Hydra no matter what one does. In actuality, there are professional services that eliminate mold and the conditions that cause it to grow, and they usually provide some level of guarantee. However, such an undertaking is not that difficult for the average homeowner to take on either.
Successful removal of mold depends on two key factors: (a) finding all of it and (b) first correcting the problems that led to microbial development. If these two steps aren't thoroughly and diligently completed, then indeed it is likely that the mold will come back. Here, professional help in the form of a pest inspection can boost one's confidence; see www.HomeInspectionWA.net for more information.
