I was referred by a friend so I was pretty confident Crystal Crystal would do a good job. They are really high recommend. Now I know why. They made sure I learned how to treat the pet stains in my carpet on my own. I received instructions BEFORE the service on how to beat treat the pet stains and on how to prepare for the entire service. One word.... EXCELLENT! Also they send the funniest text messages. I am very happy with the referral and my service from Crystal.
