    Customer Testimonial

              I would absolutely recommend sentry to family and friends. They do what they say they are going to do. They're here when they say they will be here and probably really important to me they were so respectful of our home. They were fastidious about the work that they did and really cleaned up afterwards and they did a phenomenal job.
