I have been using ChemDry for years to clean my carpets. I have a fully carpeted apartment including 12 carpeted stairs all in off white. I have grandchildren and a cat which makes the task more difficult than some but EVERY time Larry finishes the job is looks beautiful. He takes extra time to make sure the heavily soiled areas look great too. The exceptional job has added life and longevity to my carpets and I highly recommend CHEMDRY. You will never be disappointed in the results!
