They did a miracle to my home carpets! I thought there was no use hiring the cleaners from this Marietta carpet cleaning company because the carpets was full of stain and it has foul odors already. But they proved me wrong, after they clean out the carpets, I was amazed, my home carpet was like new and smelling really fresh. No discoloration and I am so impressed. They did a great job, I will recommend them to my neighbors.
