Repoint eroded bricks near drains

[babodonk]

Hi all,
Previous owners did not fix blocked drains, and over time water has damaged the surrounding brickwork.

Looks like some terrible repointing has been done previously to patch up the work.

I sent the photos to a builder who suggested repointing the back wall ( back wall of upper bedroom ) as the repointing was terrible and wrong materials used.

Is it better to repoint the whole wall, or just the damaged bricks. If it is a relatively small job, I see the merit in fixing the whole lot if it will fix the problem. But I don’t want to repair the whole lot if unnecessary.

Thanks in advance for any advice.

Best not use that builder. Just do the defective bits, but I am struggling to see where the actual problem is.

I'm dumbstruck by that weather struck pointing
