I have removed three 1.5" waste pipes from a kitchen through wall to outside.
I am wondering about patching up the external holes they have left: two of the
holes were across two bricks of different courses - and one was across three
bricks of two courses.
I could remove the remnants of the bricks, carefully remove enough bricks from
different places in a different and hidden wall - use them for repair - and put
best match new bricks in their places.

Or : I wondered about mainly filling holes with mortar - and then finishing off
with coloured mortar to match brickwork and old mortar.

Ideas or suggestions would be appreciated.

It is a tricky job for a skilled man but an amateur won't have much chance. You need to remove full brick and the mortar around them. Then replace the bricks with exact matches which will vary from not being easy to being impossible.

if you do happen to find a set of matching bricks remember they have a right way up and will be very difficult to set at the right level, angle and whatever. Then you have to try and match the colour of the compound used to join them. And not smear it all over the finished work.

Good luck with that.

any mortar instead of brick idea is going to look truly crap.

go to your local reclaim yard with the old brick to get a match. Usually easy.

if you do happen to find a set of matching bricks remember they have a right way up and will be very difficult to set at the right level, angle and whatever.

not really. Just pay attention to get it sat right.

Then you have to try and match the colour of the compound used to join them.

You won't get a match there unless determined. Just use 1:1:6 or 1:6.

And not smear it all over the finished work.

yup, take care not to. If you do, brush what you can off & come back later with brick acid.


Good luck with that.

It's all doable, just take some care over it to get it looking good.

One tip I read years ago was to pulverise an old brick, and mix the
powder with the mortar such that the mortar matches the brick colour,
then fill the hole with that. May require a little experimentation
though, to get the colour right, particularly after drying.

I once attepted that and it was a miserable failure. You need an awful
lot of pulverised brick in the mix, far too much to make for a decent
mix, to get the colour.

I would just cut out and replace the bricks. You can get the bricks to
stay level whilst they set, by inserting strips of wood or similar
under them, then once set - pull the supports out and point it.

Cut the brick in half lengthways first.
