Colorado Custom Welding offers you many choices of security doors to fit the style and needs of your home. We recently custom made a security door for a customer in Monument, Colorado who needed a large dog door to accommodate their large dogs. Just because you don’t see a design you had in mind on our website, doesn’t mean we can’t do it. We can make ANYTHING you can dream up. So large dogs, small dogs or no dogs we can make the security door that fits your needs.
