Best Dog Door For A Garage Wall: Buyer’s Guide

Picking A Dog Door For A Garage Wall

You may consider the following:

– that the manufacturer lists the walls as being a suitable mounting spot for the pet door

– what types of walls the manufacturer lists as being suitable for the door installation

– what thickness of wall the door can be mounted onto


Installing A Dog Door On A Garage Wall

The dog door should come with measuring and installation instructions – read these carefully as there is no substitute for this advice from the manufacturer.

Generally, for most Pet Doors you need to cut out a section of the wall, insert and fix a frame or tunnel extender into the wall or door, and then fix the door onto the frame (and seal and weatherproof it).

This may involve using cutting tool, a drill, a screwdriver (can be phillips head or sometimes a non standard screw is included in the kit so check this), and the hardware included in the pet door kit.

Some people choose to install themselves, whilst some people choose to get a professional handyperson to do it for them.

For the wall frame/tunnel, the standard pet door wall extender tunnels can be flimsy and not hold their shape. Some people choose to make their own tunnel or frame in the wall for more strength and security, or reinforce the tunnel/frame with packing such as timber.
