As others have said, I’ve had my carpets cleaned by multiple companies, very well known. My carpet is a beige, light brown color and many years old and showed the highly traveled areas as clearly darker than the other areas of the carpet. Cal came out to clean a darkened area to see what he could do. The area he cleaned was a tremendous improvement compared to how it looked. I scheduled him to come and do all of my carpets soon thereafter and am extremely pleased. I would recommend IntegrityClean over any other cleaning company. Something else is that Cal explained a pretty clear idea of what he will be able to do! He also explained a number of others factors which effect how a given carpet looks.
