We have used Cornerstone Chem-Dry for over 20 years…first in CA and then in McKinney, TX. We prefer this carpet cleaning process over all others. The service we have been given by both Chem-Dry companies has been fantastic. We are so grateful that we found Cornerstone Chem-Dry now that we live in The N.Dallas area. Our carpets look great and they dry quickly after the service, looking like new again
