Old brick has been acid washed - how screwed are we?
We’ve been having our 1910s/Edwardian semi fully renovated including full repointing. I came home today to find the pointing company had decided to acid wash the brick, something we hadn’t asked for. The colour of the brick is now much lighter than the other houses on the street and I’ve since read that it can be very bad to apply this type of treatment to old bricks.
How screwed are we and is there anything we can do about it?
