We have been customers of Professional Carpet Systems Superior for over ten years. They take care of our carpets for us. The last time, there was a little bit of a stain that came back. We called them about it, and we know they will take care of it for us. They are very careful in their work, and we have never had a problem. Their employees are friendly, and very polite. And, they don't make things more dirty! We have been very happy with them!
