Pet Door Glass Inserts for Sliding Patio Doors
Give your dog or cat their own way in and out without cutting into a wall or replacing your door. We install pet door glass inserts in sliding patio doors for homeowners across the Tri-Cities and Burbank.

What a pet door glass insert is
A pet door insert replaces the glass in your sliding patio door with a new double-pane, energy-efficient glass panel that has a pet door built right into it. The pet door uses an Endura Flap®, which is designed for durability and security.
Because only the glass is replaced, no frame replacement is needed. Your sliding door keeps working the way it always has, and your pet gets a permanent door of their own. It's a clean, built-in look that works for pets and homeowners alike.
Is a pet door insert right for you?
A glass pet door insert is a great fit if:
- You're tired of getting up to let the dog out (and back in, and out again)
- You don't want to cut a hole in a wall or a solid door
- You'd like to keep the energy efficiency of double-pane glass
- You want something that looks built-in, not like an add-on panel
How the process works
- Get in touch. Call or send us a message about your patio door and your pet.
- Measure and quote. We measure your door's glass and give you a free quote.
- Order. Your new double-pane glass panel with the built-in pet door is ordered to fit your door.
- Install. We remove the existing glass and install the new panel in your existing frame.
- Let them try it. Your pet gets their own door, and you get your evenings back.
