Wolverine Carpet Cleaning comes through on a regular basis to clean our facility. We have four auditoriums and they do an excellent job. The technician is very polite and goes about his business of doing the cleaning without any issues. In fact, I let him close up when he's done. They're very trustworthy folks. I've worked with them myself for the past year, but prior to that they've been cleaning our facility for at least 5 years. The pricing is very competitive.
