I want to hire someone to test my ex's home for indoor pollutants: specifically, mold, mildew and other toxins aggravated by a damp basement. The house was built eight years ago and since day 1, there has been a nasty, sour, wet-concrete smell coming up from the basement to the first floor, especially around the basement door threshhold. There is no seepage or standing water down there, but we are adjacent to wetlands and the water table is high. It's most noticeable when the AC/heat are off. Today it was so bad I could literally taste it in my mouth. difficult child 2 and easy child both have asthma, easy child's is pretty severe and she has bronchitis now. I'm wondering about whether she should be sleeping in her dad's house. What kind of profession does this type of testing and how do I find me one? Thanks!
