French doors are beautiful — all that glass, the classic look, the light they let in. So it's no surprise one of the questions we hear most is a nervous one: "I love my French doors… is there any way to add a pet door without wrecking them?" The answer is a happy yes. You don't have to choose between your French doors and your pet's freedom.
Why French doors need a special approach
Here's the key thing: the glass in French doors is tempered (safety) glass. You can't cut or drill it — it would shatter instantly. So the "just cut a hole" method that works on a solid door is off the table. Instead, a pet door goes into a French door one of a couple of smart ways, and which one fits depends on your specific doors.
Option 1: A pet door built into a replacement glass panel
The cleanest, most seamless route is to replace one glass pane (or the lower section) with a new panel that has the pet door already integrated — solid where the flap is, glass above. It's made to match, so it looks purpose-built rather than added-on. This is the same proven approach we use for sliding glass doors, and it keeps that French-door elegance intact.
Option 2: Into a fixed sidelight or adjacent panel
Many French-door setups have a fixed side panel or sidelight next to the operating doors. When that's the case, we can often fit the pet door there — giving your pet a dedicated doorway while your French doors keep working (and looking) exactly as they do now.
Will it still look good?
This is the worry behind the question, and it's a fair one. Done by a pro, a French-door pet door blends in — clean lines, a finished panel that matches the door, and no awkward gaps. The goal is always that it looks like it was meant to be there. Take a look at real glass-door installs in our gallery and you'll see what we mean.
Energy efficiency and security, kept intact
A common follow-up: won't adding a pet door make those big glass doors drafty or less secure? Not with a quality install:
- Insulated, weather-sealed flaps keep conditioned air in — no drafts. (More on that in do pet doors make your house cold?)
- A rigid locking panel seals the opening completely whenever you want it closed.
- Correct sizing and smart placement keep the opening secure.
You keep the light and the look, and gain the convenience.
