We work quite a bit with RTK because they understand our needs and the needs of our clients. RTK moves quickly and their tests are thorough, accurate, and written in an easy-to-understand way. I have results is usually only a few days and they are the only ones who can do this.

Bob was just fantastic. He took the time to explain the different tests for IAQ and mold. He located the problem without ripping up any walls, and now we have a plan to remediate specific areas rather than guessing.

I saw a segment on the Today Show about crooked mold contractors. As luck would have it, RTK Environmental Group was the reputable mold testing company that the Today Show both mentioned and used! RTK did our mold “investigation” (as they call it) and literally saved us from paying $12,000 unnecessarily!

At first, I was a bit hesitant about the price because there were all of these companies offering free mold testing. I spoke with Bob the owner who explained to me how these “free testing” companies work. They offer you a free mold test, find mold (whether it’s there or not!), and then charge you a bundle to remove it. I may have paid a little more up front, but in the end I saved thousands.
