Excellent Product
What a fantastic door. I started looking at this door a month ago and could not believe all the options as far as colors, sizes, etc. I ordered, received it in 1 day, installed in a short amount of time and my dog loves it. When I called in to place my order the rep was very knowledgeable and friendly. Everyone who owns a dog should have a Max Seal!

Happy Pooches!
My dogs and I love this door. It is sturdy and maintenance free. My dogs tear through the flaps. I wish I had found you guys before now, I would have purchased a long time ago. Thanks for a great door!

Best Dog Door Ever! | MaxSeal Pet Door
I recently bought this MaxSeal Dog Door by Security Boss and WOW what a pet door it is!!! I was skeptical that it coyuld perform as advertised, but it actually did better than I could ever hope. We have occasional winds that can be very strong, but the MaxSeal kept nearly a perfect seal in all conditions. My two Rottweilers use this door at least 50 times a day and it also withstands the beating they give it. Thank you for a great pet door...it is nice to receive great customer service along with a product that out-performs your greatest expectation. I am recommending this to all my close dog loving friends evey chance I can!!

Marvelous Door
I love this door and so does my cat. It was very easy to install. It was a bit tricky to get my old cat to use the door but I called in and the customer service rep was very helpful. Gave me a few tricks to try and after a couple days the cat figured it out just fine. I would recommend this door to anyone.

Top Notch!
I needed a big door for my Dane and the old pet door I had installed before fell apart from constant use. I've had this door installed for just over a year now and I have never had any problems to date. Wow does this door insulate too! Big pet doors are hard to find for my breed, but this MaxSeal has been the answer I was looking for! Thanks for the great product!

Worth every penny!
I have never seen a pet door as well built or as well insulated as this MaxSeal pet door. I replaced my Petsafe doggy door with this new MaxSeal pet door and overall it's head and shoulders above the Petsafe door. Thanks for the $15.00 credit for me sending in pictures of my pet using the door also!

Awesome product!
I was hesitant to spend over $100 on a dog door, but I am sure glad I did! This MaxSeal pet door has been a life saver letting my dogs in and out and keeping the cold out! Especially being from Maine the insulation is a life saver and I would recommend this door to everyone without hesitation!

GREAT PET DOOR
We got this for our large dogs who love to fly through the house at top speeds. The flaps have held up and it works great. We don't ever feel a breeze when it gets cold during the winter months either. Would definitely get this product again if I ever needed to.

A High Quality Pet Door
The MaxSeal is an industrial grade pet door. The dog door was very simple to install and it's easy to use. They weren't kidding when they said Security Boss makes high quality products. This dog door feels like it will last a lifetime. Very happy with this one.
