We have pretty nice carpet in our rental house and it has stood the test of time until our last tenants. When they left, it looked pretty beat up up with spots all over, and a few we were not sure would come out. Chem Dry did an analysis of what was needed and we got the full treatment. The results were amazing! Looked like new and saved us probably $2500 in new carpeting. Even my husband, who is a real stickler about the condition of the rental house, was super satisfied.
