Foundation repair in Portland runs $4,000–$15,000, pilings $1,200–$3,000 each. Newer streets often mean post-tensioned slabs, which changes what repair is possible before anything else is discussed.
Up on the bluff, and mostly newer
Portland sits higher than much of the region and a good deal of it was built from the 1960s onward, which means slab-on-grade construction throughout and a fair number of post-tensioned slabs in the newer parts of town.
Elevated ground drains better, which cuts one problem and sharpens another: better drainage means faster drying, and faster drying on clay means a wider swing through a rainfall deficit.
Find out which slab you have
On the newer streets it is worth establishing whether the slab is post-tensioned before anybody proposes cutting or coring anything. It changes what repairs are available and it changes who should be holding the saw. The detail is on the post-tension page.
Asked in Portland
How much does foundation repair cost in Portland?
Complete jobs run $4,000-$15,000 with pressed pilings at $1,200-$3,000 each. On the newer streets, establishing whether the slab is post-tensioned comes before anything else, because it changes what repairs are available.
How do I know if I have a post-tensioned slab?
Look for a stamped warning at the garage slab, or small patched circles in a regular pattern around the slab edge - those are the anchor pockets. Construction documents settle it outright, and so does the builder on a newer house.
Does being up on the bluff help?
It helps with drainage and hurts with drying. Better-drained ground sheds water faster, which on clay means it reaches its dry-state volume sooner in a deficit and swings further when rain arrives.
Establish the slab type before anyone cuts
Check the garage wall for a stamped warning and the slab edge for grouted anchor pockets. If it is post-tensioned, that fact needs to be on the table before a contractor proposes coring anything.

Two things help most before we get there: roughly what year the house went up, and whether the trouble showed up during a dry spell or after heavy rain. On this ground the season it appeared in narrows the cause faster than the size of any crack does. Expect a reply the same working day.
