What you did sounds right for a homeowner. A more permanent solution might require renting equipment or hiring someone, but if your fix worked for 13 years, that seems like a decent investment of time.
We did a job in Scarborough last week.

Small world! That's south of me.
Yeah, fortunately I only have a couple of posts to shim or replace. I used a 20ton bottle jack, wood blocks and some steel plate the first time. The bottle jack barely did the job. I dug down about 1.5ft, laid down wood blocks, a steel plate, the jack, thick steel plate, more blocking. The more I jacked it, the deeper the blocks under the jack were driven into the ground. Seriously heavy. I need to pick up a 50 ton bottle jack for the next time - and something rugged with a bigger footprint for support. I have a couple of old antique house jacks and a crow bar, but they would probably suck to use in this application. So I have a plan on how to lift it, but nothing final on actually replacing the tilted/damaged supports. That area has sagged about 1" - 1.25", not too bad - yet.

It sounds like you might need a gravel pad under your jack.
Sounds like a good idea from someone who has had to deal with similar situations (at much larger scale).
After digging down 1.5ft the last time, I hit gravely glacial till type material and it seemed quite hard and compact. Apparently was not.
Maybe a bag of river rock from Lowes would do it? Make a 4"-6 thick"pad slightly larger than the base of the wood blocks supporting the jack? That might be more convenient for me, gravel has a lot of fines in it, the amount of rock varies unless I can get a small quantity of State highway grade gravel somewhere.
