Admittedly, I balked at the cost of the custom security door, but after having it for a couple weeks now, I'm so glad we got it. We wanted a security door with a dog door since we have two dogs that can never decide whether they want to be inside or outside, and we couldn't find a quality product until we came across this company. We worked with Ken, and he did a great job communicating about the job, the costs and type of products available. The best part of the door -- aside from the freedom of the dog door -- is that it is custom fitted and sealed tight so we can still have it "open" (locked for people, open for the dogs to go back and forth) and it protects against the outside temp. For instance, it's 40 degrees out right now, and I can't feel any cold coming through that door.
So, if you're looking for a custom dog door/security door, I can honestly say that this is a good company to work with, and I'm very satisfied with the quality of the product.
