We are an oilfield company so of course our carpets get dirty and grimy. We have used several other carpet cleaning companies and the floors looked great - for about 3-4 days and then the stains would start seeping thru again. We called Miner's Chem-Dry and they not only got the carpets completely clean, but they were able to fix the problems caused by the previous companies! We use them on a regular basis now. They always call to follow up after a job just to make sure it was done correctly. (and of course it was) Best of all - they are reasonably priced!
