I wish I could give more than 5 stars. When I called the office they were very helpful. I was desperate to get out dog door in as soon as possible. We had just moved and with 3 dogs and a teacup pig and no dog door was getting kinda messy. JGM sent someone out the next day. I have French Doors that are expensive, high quality and double pane. JGM came out and could have installed the door but the installer called the office and they decided to come back the next day with custom pieces because it would fit better and look much nicer. As promised JGM showed up the next day on time, called ahead and was very professional. The door looks amazing! The installer worked very hard to not break any glass and save all the pieces for any reason we would need to remove it. He packaged up all of the pieces and labeled it for me. I love love JGM Pet Doors! If you need a dog door this is the company to use.
