Ways to save in Petaluma
- Pay an independent structural engineer $400 to $1,200 first so you buy the repair you actually need, not the one being sold.
- Fix drainage, gutters and grading — many settlement problems stop progressing once water is controlled.
- Get three bids with pier counts and depths spelled out; counts vary wildly between contractors.
- Ask about interior versus exterior pier placement — exterior is usually cheaper.
- Choose a company offering a transferable lifetime warranty; it protects resale value.
