My 736 sq/ft house currently sits on cinder blocks (not a good foundation). I am looking into possibly putting it on concrete piers (sonotubes).
Is this a good idea?
What seems to be the problem with the block foundation? Can it be repaired (re pointed) and have a company come in and dampproof it properly?
In my opinion pillars are not recommended for replacement of a foundation wall. Is it a crawl space or full basement? If it absolutely needs to be replaced, you should have a company come in raise the house and get rid of the block and pour a concrete foundation. If your lucky the footings are still in tact. Pillars (pilings) are only recommended in certain building practices where the ground is silty (sandy conditions). Hope this helps

Are the blocks supporting your house, piers or a wall, If their piers and not tipping or broken there's no need to have them replaced, If there sitting on a pier pad (floating foundation) that's leaning have them repaired by a contractor who has experience and insurance. Putting in sonotubes below the frost line, can have there own set of problems that are not easily to repair.
Other options for a below frost line walls (crawl space) is a pressure threaded foundations if your soil type is suitable, they last 50+ years.
Any replacement is a structure issue and requires a permit, talk to your local planning department for some advice.
