We've used COIT in the past, and hadn't been too happy with the results. Tried Naturell based on Angie's list review. They answered the phone when I called (not all places do this believe it or not), gave me a quick quote, and scheduled the appointment the same week. The team of two showed up and were professional and pleasant. Quite simply and to the point, the carpets wound up being cleaner than I've seen them since we had them installed, which is no small feat with light-colored carpet, two young kids and black-haired dog. Their process resulted in nearly-dry carpets when done, which is a plus compared to the soaking wet carpets we've had from other providers. Better yet, my kids and dog weren't exposed to anything harmful.
