Step-by-Step Guide to Installing a Pet Door in Glass

Installing a pet door in glass requires significant planning and specialized tools. Here's a detailed guide to help you through the process, ensuring that both your pet and your home are secure and comfortable.

Understanding the Options

Typically, you wouldn't install a pet door directly into a glass door. Instead, pet doors are commonly installed in either the glass patio door's side, under an upward opening window, or in a solid wall adjacent to the patio door. However, for customized solutions like adding a pet door in a sliding glass door or a custom-sized door, the process becomes more complex. This article focuses on a unique situation where the author needed to fit a custom pet door into a large sliding glass door while maintaining space for personal mobility.

Professional Installation for Glass Doors

For those considering a pet door in a glass door, professional installation is strongly recommended. Cutting through glass requires expertise to ensure the integrity of the glass and the safety of the pet. A professional can also ensure that the pet door is installed securely and does not compromise the overall structure of the glass door.

Planning and Research

The author's pet, a large dog, required a custom solution because the dog door needed to be large enough to allow the pet easy access, but also provide ample space for the owner. This necessitated extensive research and planning. Factors like the longevity of the product (flaps wearing out after a year), snug fit, and magnetic base strips were all carefully considered.

Alternative Solutions

When traditional options like inserting a pet door in an existing patio door or under a window were not feasible, the author explored alternatives. Adding a beam across the desired height and a vertical beam to support the doggy door was initially considered, but logistical and cost issues made this impractical. The final solution involved purchasing an insert, which meant the pet still needed to walk around to another door.

DIY Installation Steps

For those attempting a DIY installation, here are the steps to safely and effectively install a pet door in glass:

Remove Glass Stops: Use a putty knife or similar tool to remove the glass stops from the frame. Set them aside for reinstallation later. Separate the Glazing Tape: Carefully use a putty knife or razor knife to separate the glass from the frame. Be cautious not to drop the glass unit while freeing it. Remove the Existing Glass: Carefully tip the top of the glass unit out of the frame and remove it. Dispose of the old glass unit properly. Remove Old Glazing Tape: Using a razor knife or putty knife, scrape away the old glazing tape and clean up the frame, ensuring not to damage the edges. Apply New Glazing Tape: Apply new glazing tape along the inside of the door frame to ensure a tight seal. Insert the Pet Door: Ensure the glass shims do not cover the slots for the glass stops. Carefully insert the bottom of the pet door unit and work it into the frame, applying pressure as needed. Reinstall Glass Stops: Gently tap the glass stops back into place using a soft mallet, starting with the longest pieces. Reattach the Door: Place the door sash back into the frame, starting from the top and lifting it over the bottom lip.

Conclusion

Installing a pet door in glass is a specialized task that balances the needs of the pet and the homeowner. Whether it's a DIY project or a professional installation, thorough planning and attention to detail are essential. For those who opt for a custom solution, doing extensive research and considering all aspects of the project is crucial to ensure the best outcome for both the pet and the homeowners.
