What Iowa foundation and basement work costs, as published
Four sourced figures, and a guide to comparing written estimates. None of it is a quote.
We do not price jobs and we do not bid on work. These are figures published by other websites, shown with where they came from and when we read them, so you can tell if an estimate is far from the usual range.

The spread is wide on purpose. A single crack injection and a wall brace system sit at opposite ends of the same word, foundation repair. Treat the top of the range as the bigger, structural jobs and the bottom as small, local fixes. We are not publishing more figures until we can trace each one to its own page.
Why a Cedar Rapids price can move
- Digging outside a house on a tight lot costs more than a house with open space on one side.
- Water work such as drain tile and a sump adds to any structural bill, and in a flood affected neighbourhood it is more likely to be needed.
- Permit requirements differ between Cedar Rapids, Marion and Hiawatha. See permits.
- A wall that has moved a long way costs more to fix than one caught early, which is why dated photos and a check every few months are worth the trouble.
Comparing two written estimates
Put them side by side and ask the same five questions of each. What method? How many braces, anchors or piers and where? Who designs it? Who pulls the permit? What does the warranty cover, and does it pass to a buyer? An estimate that skips the water source is not the same job as one that deals with it. When the numbers differ, ask each company to explain the gap before you pick the cheaper one.
Next step: learn what kind of crack you have, then send a request.
