Choose a location

To select the best location for your pet door, consider:
  • Accessibility: Ideally, place the dog door near your pet’s primary living space.
  • Installation: Consider the challenges in installing a dog door in the kind of exterior door in which you want to put it.
  • Appearance: Consider the aesthetics of placing the pet door in the location you have in mind and arrange for increased traffic in the area of the new pet entry.

Pets need to lead a happy, comfortable life, and installing pet doors are one way to enhance their living. There are several benefits associated with pet doors, which include:
  • They help pets live actively since regular movements act as a form of exercises, thereby stimulating their mind.
  • Boredom related conducts like chewing pillows, clothing, and other items in the house are significantly minimized.
  • When a cat or a dog engages in movements, their confidence and boldness greatly increase.
  • A pet door allows them to endorse freedom in performing various activities such as relieving a call of nature.
Usually, “Through the Glass” dog doors consist of glass panels with an upper glass portion and a doggie door glass insert at the bottom. Manufacturers will deliver the whole package as one unit with the dog door already pre-installed. This glass panel can either fit into the old patio frame, or a customer can purchase a new frame since the package does not include one. Installing the frame plus the glass panel, one might have to hire professionals from a glass door installation company.
If a pet door flap gets broken or faulty, then it necessitates replacement. Although this can only happen after a prolonged period or if unintentionally interfered with, our company sells replacement parts and hence you need to make an order.
Here are significant considerations you need to make while taking your dog’s allowable measurement.
  • Height of the flap: The height of your pet from the ground up to its shoulder level should help you determine a suitable flap’s height. It should be slightly above the tallest pet’s shoulders.
  • Width of the flap: Your pet’s shoulder breadth should guide on the width as well. It should leave an allowance of at least an inch from both of the pet’s sides.
  • Door size: Ultimately, available dog doors in the market determines it all. Various sizes are available for sale, and hence you should select one that matches the size of your pet.
Besides the cost of the pet door, hiring a professional will incur you depending on the size of the project. The period it would take to finish installation depends on the condition of the door frame to be replaced, which influences the overall cost. Usually, you can request for a customized quote through our website which has provisions of including a professional installer for you.
