### Looking to install a pet door without replacing your entire patio door?

Our customer in [**Silver Spring, Maryland,**](https://www.allds.com/service-areas) wanted a convenient way for their dog to access the backyard while preserving the appearance, security, and energy efficiency of their existing exterior patio door. Instead of replacing the entire door, **All Dwelling Solutions** provided a custom glass replacement solution designed specifically for a built-in pet door installation.

For this project, we custom-ordered **insulated tempered Low-E glass.** The insulated glass was professionally manufactured with a **custom cut-out** to accommodate a **MAVRICFLEX Medium Heavy Duty Doggy Door**, creating a clean, factory-style appearance while maintaining excellent thermal performance.

The selected **MAVRICFLEX Medium Gray Doggy Door** features durable aluminum construction, magnetic double flaps, dual sliding security panels, and is designed for dogs up to **40 pounds**. This solution provides convenient pet access without sacrificing insulation, weather resistance, or the overall look of the home's back patio door.

Our installation process included carefully removing the existing insulated glass panel, preparing the opening, installing the new custom insulated glass unit with proper setting blocks and spacers, applying professional-grade glazing sealants for an airtight and watertight seal, reinstalling all trim components, and performing a complete quality inspection to ensure smooth door operation and a flawless finish.

The result is a professionally integrated pet door that looks like it was installed by the original manufacturer—not an aftermarket insert—allowing the homeowner to keep their existing patio door while giving their pet safe and easy access outdoors.
