Hi,
I need to install a cat flap in my kitchen wall. It is a single skin brick wall (1930s red brick) with plasterboard and insulation behind.
How easy is it to cut the hole out for this? I have some long masony drills etc, but am unsure as to how much you knock out. i.e. can you drill holes in a line through the brick to create the hole of the required size or do you have to knock out the surrounding bricks and fill in around it afterwards?
Apols for sounding like a novice, but have never had to do this before.
TIA
Will Owen
