I hired Steven's Chem-Dry after my dog got sick on the carpet, and I didn't think the stains were ever going to come out. I have used Steven's before, and this time I was concerned because it seemed like they used too much pre-treatment. I was worried that they had made a mistake, so I called in to speak with them. They were very responsive and let me know that they would take care of it. They reassured me that everything would be fine. I wasn't sure if this was the case, but I trusted them, and they were definitely right. All of the stains came out, and the carpet was so amazingly clean that my roommate thought I had purchased new carpet! They did a fantastic job. Overall, although I thought their prices were a tad high, I cannot complain after the quality of the work that they did.
