Talk about professional. When you first call Eddie he tells you everything you need to know. He Is straight to the point and gets the job done fast and clean. We just purchased a new home and had Eddie install a medium size Hale pet door for our two Frenchies. We called him about a week before the installation date. I suggest you call ahead of time because he does seem pretty busy. The pet door was installed in the side of our house on a wall. It turned out Purrfect!!! We will definitely recommend him to all our friends.
