Healthy Home Mold Inspection

I noticed some black staining areas on a baseboard in my Naperville home and I was worried I might have black mold. I call a mold remediation company and even though they couldn't confirm 100% that the area was mold they wanted to replace most of my wall. I called Healthy Home Mold inspection, they came out the next day and tested the area with a swab, then tested the air on all three floors of my home. Good idea to call a mold testing company before calling a mold remediation company.
