The pointing is a mess, the actual gaps are where I’ve repaired/ replaced bricks in recent memory so the mortar there is fine.
But I’m planning to put a corner window in what used to be the outside privy- but is now where my sink is - so it can all get re-done then.
That pointing looks like it might need a bit of work soon.
What's the mortar like behind it? We found that ours had turned to sand, once the cement had fallen out.
