Crawl Space and Pier-and-Beam Assessment
Engineering evaluation of sagging floors, rotted sills, failing piers and beams in crawl space and pier-and-beam homes.
What the work involves
An engineer evaluates piers, beams, joists and sills under raised floors, looking for rot, termite damage, settlement and undersized framing. The report specifies shimming, new piers, sistered joists or beam replacement. Moisture control recommendations are often included.
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
- Bouncy or sagging floors
- Visible rot or termite damage in the crawl space
- Piers leaning or sinking
- Contractor proposes adding many jacks without explanation

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.
