Hire an Independent Inspector
A mold inspector tells you whether you have a problem, where it is and what caused it. A remediator removes it. When the same company does both, it has a reason to find mold. If you can, hire an inspector who does not do remediation, and ask the remediator to follow that inspector’s written plan.
Ask the inspector what the visit includes. A good one looks for the moisture source first, uses a moisture meter and often a thermal camera, and only takes air or surface samples when the result will change what you do. After the work, a clearance test by the same independent inspector shows whether the job is done.
Can You Handle It Yourself

Home test kits that grow spores in a dish almost always grow something, because mold spores are everywhere. They cannot tell you whether you have a problem. A moisture meter and a flashlight will tell you more for less money.
