Last week I had called All about pet doors. I was able to get an appointment with in a couple days. They brought the doggie door with them since i wasn't sure which one to purchase. Very helpful. They came and installed it. They stayed in the time frame the said they would. Pricing was reasonable too. They did a very good job. I haven't found any flaws at all. It looks very professional! I would recommend all about pet doors to any one!
