Dog Door Through Stucco Wall - No Shortcuts Taken

Installing a dog door through a door is one thing. Going through a stucco exterior wall with insulation, drywall, and an aluminum tunnel sleeve? That's a different job entirely. This one required some real problem-solving before everything came together the right way.

We used the High Tech Pet Armor-Flex door with the wall tunnel sleeve - a solid unit built for exactly this kind of installation. It's weatherproof, energy efficient, and has a magnetic locking flap that keeps drafts out. Good product. But good products still need to be installed right, and that's where the work really happens. The cut through the stucco exterior had to be clean and precise, the insulation had to be cleared and managed properly, and both the interior and exterior frames had to sit flush and tight against their surfaces.

The interior side sits mounted cleanly against the drywall, framed out neatly - and the exterior comes through the stucco with the tunnel sleeve filling the wall depth completely. No gaps, no slop. The flap sits right at ground level on the exterior so the dog isn't stepping up or awkwardly crouching to get through. That stuff matters.

Every home has its own quirks. Wall thickness, insulation type, what's inside the wall cavity - none of it is guaranteed to cooperate. We work through those details instead of around them, because cutting corners on a wall penetration like this leads to drafts, water intrusion, and a unit that just doesn't sit right. That's not how we do it.

The end result is a dog door that functions the way it should and looks like it belongs there - on both sides of the wall. Clean on the inside, clean on the outside, and built to hold up.
