Cable wall tie failure (help)

Grenage

It's not particularly complicated.  I just knocked the heads off mine where the courses had lifted and repointed.

Drilled/screwed in replacement ties.

As with all things, it's the labour that costs.  Some walls are probably going to be a lot more work than others.

Can I just ask a naive question, please. Why does the remedial work require a lot of rebuilding? Is this because the first you know about the wall ties rusting through is when the wall bulges?

It depends on what type of ties you have. The thin butterfly ones will rust away without cracking the brickwork, but the thicker twist ones will expand enough to cause horizontal cracks. 
With the thin ones the first signs are usually the brickwork bulging out, especially on the gable end.

We had cavity wall ties fail on the rear gable of our house, which gets all the weather.  1947 with fishtail ties.

We had the outer skin above the windows taken down and rebuilt.  I think it was £2-3k.

The bricks are a great match. Did they clean the old ones up?
