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 and frost heave
- Heavy snow loads
- Riverine and spring snowmelt flooding (Red River)
- Peat and soft organic soils
Building code: 2018 IBC/IRC adopted at the state level (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
Frequently asked questions
How much does crawl Space and Pier-and-Beam Assessment cost?
Across the US, crawl Space and Pier-and-Beam Assessment usually costs $300 to $1,500 per inspection. Estimate. Angi lists pier-and-beam repairs at $750 to $25,000 depending on scope.
How long does crawl Space and Pier-and-Beam Assessment take?
Plan on 1 to 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 crawl Space and Pier-and-Beam Assessment?
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 Minnesota?
Engineers practicing in Minnesota are licensed by the Minnesota Board of Architecture, Engineering, Land Surveying, Landscape Architecture, Geoscience and Interior Design (AELSLAGID). 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 Minnesota?
Minnesota Rule 1303.1600 sets minimum footing depth for frost protection at 60 inches in Zone I (northern counties) and 42 inches in Zone II (southern and metro counties), unless an engineer competent. 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 Minnesota?
2018 IBC/IRC adopted at the state level (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.
