I have a screen door that my pitbull has ripped through several times. In the past I have replaced it myself, but the dog would always rip through it again. From their web site, I noticed they had Tuff Screens with a 5 year guarantee that they will be replaced at no charge should the pet rip through it. They were able to fit me in just 2 days after making the appointment. I had an appointment at 4:00 but they called at 3:00 asking if they could come over early because their current appointment wasn't there. I was at work, but said they could get started as the screen was accessible from the back yard. I left right away from work (I work 5 miles away from home), and by the time I got there, they had arrived at my house and completed replacing the screen. They did a good job, but the screen material doesn't seem to be significantly different than the pet resistant screen material they sell at the hardware store which I have used in the past, and gets ripped through by my dog. We'll see, but I intend to take advantage of the 5 year guarantee should the dog rip through it. The screen door was apparently also off the tracks and they put it back on at no extra charge, which was nice.
