Does anyone have a recommendation for an installer to put a cat flap into a brick wall? Maybe also to supply the microchip cat flap at the same time? Many thanks, Philip
Happy to loan you long masonry drills or a 50mm core drill if you want to attempt Diy?
There should be no need to add any support as hole will be quite small (as opposed to say a window) if the wall is a solid 9" or possibly 11" cavity then careful drilling should be simple with cement to trim. Alternatively you can get glass with flap cut out for a door. I would imagine the cost would be high as a tradesman would allocate a day to complete even if only a couple of hours work.
