This is the third time I have used Steven's Chem-Dry Carpet Cleaning. I like the method they use to clean carpets. This last time that I used them, a few days ago, my septic system backed up, and it was bad. My carpets needed help right away. I called them, and they arranged to come out that same day, and they dried out the carpet, and they applied various chemicals. They are coming back out today to do the actual carpet cleaning for me. They do a good job, and they are quick to come out when I need them. They work efficiently, and I really appreciate how responsive they were! Their work is perfect!
