Pet Doors for Walls, Through the Wall Dog Door Installation

Professional Wall Mount Dog Door Installation Nationwide

Portal Pros specializes in pet doors for walls and professional wall mount dog door installation. When your door, patio slider, or glass is not the right place for a pet door, going through the wall is often the best long term answer. A through the wall dog door gives your dog or cat direct outdoor access from the exact spot that works best for your home, while your main doors, patio doors, and entryways stay untouched.

We install wall pet doors in walls 2 inches to 10 inches thick, covering standard 2x4 and 2x6 framed walls, stucco, brick, block, and siding, with insulated wall pet doors, chew proof wall dog doors, and custom wall mount pet doors for anything outside standard sizing. Every installation includes a fully framed and sealed tunnel, finished trim inside and out, and a locking security panel, done by a licensed professional installer.

Why Choose a Pet Door for a Wall?

A pet door for a wall is the most flexible installation type there is. Instead of being limited to wherever an existing door or glass panel happens to sit, a wall mount pet door goes in the location that makes the most sense for your home and your pet: straight out to the backyard, next to the dog's favorite spot, at the right height for a large breed, or anywhere daily traffic flow works best.

Wall mount dog door installation is also the right choice when you want to preserve your existing doors. Rather than cutting into a front door, back door, or patio slider, we install the pet door through the wall and finish it into a clean, intentional entry point built specifically for your pet. If you ever sell the home, your doors are exactly as the builder made them.

Professional Wall Mount Dog Door Installation

Installing a dog door in a wall is more than cutting a hole. It requires locating studs, wiring, and plumbing before the cut, precise measurement, clean cut work through the interior and exterior faces, a properly framed tunnel tipped so moisture drains outward instead of into the wall cavity, interior and exterior trim out, and full weather sealing on both faces. Done right, the finished result looks like the house was built with it.

Portal Pros installs wall pet doors built for real daily use: insulated dual flap systems, magnetic seals, strong locking security panels, and durable frames, with premium models for high traffic and multi pet households. If you want a wall dog door that looks clean and seals tight for years, professional installation is the difference.

Pet Doors for Walls 2 Inches to 10 Inches Thick

Our standard wall collection covers walls from 2 inches to 10 inches thick, which handles the large majority of residential construction: 2x4 and 2x6 framed walls with drywall and siding, stucco over foam, and most brick and block applications. If your wall falls in that range, we can usually recommend a standard or premium wall mount pet door that fits the opening and performs the way you want.

Thicker walls, unusual rough cut dimensions, and specific frame constraints are handled with our custom wall mount pet doors, fabricated to order for walls up to 16 inches deep. If you are not sure which side of that line your wall falls on, text us a photo and we will tell you.

Benefits of a Wall Mount Dog Door

A wall mount dog door gives you total freedom of placement, which usually means better usability for your dog, a cleaner look for the home, and zero compromise to your existing doors and windows. It is often the best dog door option for large breeds, because the opening height and location are chosen for the dog's comfort instead of being dictated by an existing door panel.

A properly installed wall pet door is also the most permanent feeling result available. Finished trim inside and out, a sealed insulated tunnel, and a flap system built for daily use add up to an access point that looks and performs like part of the house, not an accessory bolted onto it.

Custom Wall Pet Doors for Unique Applications

Not every project fits a standard size. If you have an unusual wall thickness, a specific frame requirement, an existing rough cut from a previous pet door, or a unique installation condition, our custom wall pet doors are fabricated to order around the actual job. Custom is especially useful for matching an existing rough opening exactly, fitting a giant breed precisely, or working within a hard limit on overall frame size. When custom is the right answer, we verify every dimension on site before the unit is fabricated, since custom units are nonreturnable once built.

Insulation, Weather Sealing, and Performance

A hole through your exterior wall has to be sealed like the rest of your building envelope. Our installations pair insulated dual flap pet doors with a properly framed, sealed, and outward tipped tunnel, so the finished result blocks drafts, sheds moisture, and holds up season after season. In hot climates, cold climates, and windy areas alike, the difference between a premium insulated wall pet door and a cheap flap in a hole shows up on your comfort and your utility bill.

How We Help You Choose the Best Wall Pet Door

The best wall pet door depends on your pet's size, how hard the door will be used, your wall thickness and material, your climate, and whether the job calls for standard, premium, chew proof, or custom. Some homeowners want the most insulated wall pet door possible. Others want a budget friendly standard option. Some need a chew proof wall dog door for a powerful dog, and others need a custom wall pet door built to a specific opening. Text us a photo of your wall and your dog and we will narrow it down for you, so you never end up with a pet door that is too small, poorly placed, or not built for the way your dog actually uses it.

Wall Pet Doors for Small Dogs, Large Dogs, and Multi Pet Homes

Our wall collection covers everything from a compact cat door for a wall to an extra large wall dog door for giant breeds, with tougher options for high traffic multi pet households. Sizing matters as much as product choice: measure your pet's shoulder height and add about 2 inches for the opening, measure the widest point of the body and add at least 2 inches for width, and set the installation height so your pet steps through naturally. We confirm all of that with you before anything is ordered.
