Foundation Crack Evaluation
Is that crack cosmetic or structural? An engineer measures and evaluates foundation, slab and wall cracks.
What the work involves
Not every crack is a problem. An engineer looks at crack width, pattern, displacement and whether it is active, along with related signs, to separate shrinkage cracks from settlement, heave or lateral pressure. The engineer may recommend monitoring with crack gauges, simple sealing, drainage fixes or structural repair.
Local conditions we plan for
- Deep frost penetration
- Heavy snow loads
- Great Lakes shoreline erosion
- Karst in the southwest Driftless Area and Door County
Building code: IBC 2021 statewide for commercial buildings; one and two family dwellings use the state Uniform Dwelling Code instead of the IRC (ICC adoption chart, April 2026).
When you need it
- Horizontal crack in a basement wall
- Stair-step cracks in block or brick
- Crack wider than about 1/4 in. or with one side offset
- Cracks that are growing or reopening
- Slab cracks with heaving or sinking
Frequently asked questions
How much does foundation Crack Evaluation cost?
Across the US, foundation Crack Evaluation usually costs $300 to $1,000 per inspection. Estimate based on Fixr ($300 to $600) and This Old House ($300 to $1,000) inspection ranges. Simple crack repair runs about $250 to $800 per Angi.
How long does foundation Crack Evaluation take?
Plan on Same week visit; report in under 2 weeks from signed proposal to stamped deliverables, longer if a site visit, soil testing or a permit review cycle is involved.
Is a permit required for foundation Crack Evaluation?
Often not on its own, but the findings frequently lead to work that does need a permit. We tell you which parts of the follow-up work your local building department will review, and can prepare those drawings too.
How do I verify an engineer's license in Wisconsin?
Engineers practicing in Wisconsin are licensed by the Wisconsin Examining Board of Architects, Landscape Architects, Professional Engineers, Designers and Professional Land Surveyors. You can confirm a license number and its status in the board's public license search before you sign a contract.
How deep is the frost line in Wisconsin?
Wisconsin Uniform Dwelling Code SPS 321.16 requires footings to be below frost penetration or at least 48 inches below adjacent grade, whichever is deeper (one and two family dwellings). Local building departments set the required footing depth, so confirm the exact figure for your county before designing foundations or retaining walls.
Which building code applies in Wisconsin?
IBC 2021 statewide for commercial buildings; one and two family dwellings use the state Uniform Dwelling Code instead of the IRC (ICC adoption chart, April 2026). Cities and counties can add local amendments, which is one reason to hire an engineer who works in your area.
