My son is in the process of purchasing his first home and we have found some termites in the walls of several rooms. A extermanator looked at the house today and thinks is a recent infestation and didn't find anything outside. It's a old ( 50s ) house that has some kind of fiberboard not dryway walls. They think the damage is pretty much between the surface of the fiberboard and its paper coating. Their going to treat and said we could skim coat the areas to repair the damage. It seems to me that with out cutting the areas out I'd be just hoping and guessing as to the extent of the damage. Wouldn't the proper approch be to cut it out say 3 to 4 feet and replace the area with drywall ???? I don't want to waist money but I want to get it done right .......Any insight would really be great !!!!
