What’s the difference between a retrofit and a new or remodel/replacement installation?

A retrofit installation is for individuals who have an existing pet door. The Smart Pet Door mounts onto your existing pet door frame in seconds with no professional installation required. If you do not have an existing pet door, or if you want to replace/remodel your existing pet door, we offer complete pet door systems for a seamless installation. The Smart Pet Door works with our heavy-duty Tunnel and Frame to create the ultimate maximum security pet door system, designed to be professionally installed.

Can the Smart Pet Door be installed in my brick or block wall?

Yes. The Smart Pet Door can be installed in any exterior wall material including brick, wood, stone, metal, aluminum, and more. Please refer to our installation guide for step-by-step instructions.

Does the Smart Pet Door have to be installed onto a door?

No. The Smart Pet Door can be installed directly onto the interior wall of your home, onto a glass door or window using our Glass Mount Kit, and of course, onto your door.

Can I install the Smart Pet Door onto my sliding glass door insert?

Yes. The Smart Pet Door can be installed onto your sliding glass door insert using the sliding glass door mount kit.

Four-Season Dog Door Choices in Kingsport

Kingsport has roughly 13,300 owner-occupied detached homes, equal to 53.3% of occupied housing. Many offer direct exterior access, while leased or governed properties may require approval.

Regional records show ample rainfall and a defined freeze season. A covered route, insulated weatherstripping and drainage away from the threshold help manage wet weather and cold snaps.

Wall depth and finish can vary with siding, brick veneer or masonry, so locate structure and utilities before setting the opening. Door layouts need clear space outside panels, glazing and locks.

A fitted slider insert may preserve the surrounding wall if the passage remains practical. Tempered or dual-pane glass requires a replacement unit manufactured with the opening already formed.

Match pet dimensions and seasonal exposure to the safest compatible retrofit, door, wall, slider or custom-glass path.

Replacing or covering an existing pet door opening

Plan before you cut

Before you hire a pet door installer

Choose your pet door before your installer begins cutting or modifying your home.

Your installer may need the product’s exact opening dimensions, mounting requirements, wall or door thickness limits and any required frame, tunnel or glass-mount components. Selecting the product first helps avoid creating an opening that is too large, too small or incompatible with the pet door you ultimately want.

Pawport provides detailed sizing information, installation manuals and product specifications that can be shared with the professional completing your installation.
