What a foundation repair job actually involves
A foundation holds the house up and keeps the ground out, so a repair is any work that stops the structure moving or restores its support: sealing a crack, bracing or rebuilding a wall, adding support under a footing, or fixing the drainage that is pushing on it.
University of Minnesota Extension, an out-of-state source used because we could not read a Michigan one, says concrete and block foundations usually develop some cracks, that they can be severe if floor joists are not connected to the wall, and that soil settling causes cracking. A crack alone tells you little; what matters is whether it is still moving.
What foundation repair costs in Michigan: estimates, not quotes
Our estimate for a foundation repair project in Michigan is $2,300 to $8,375 per project. It is a model, not a quote: it takes two published national ranges and adjusts them by Michigan's cement mason wage ratio (1.05). We have collected no Michigan quotes, and we found no Michigan company that publishes a price. The wage and permit rows below are not prices; they show what workers are paid and what some cities charge for permits.
| Item | Figure | What it is |
|---|---|---|
| Estimated range, not a quote | $2,300 to $8,375 per project | Built from 2 national published ranges, adjusted by the Michigan cement mason median wage ratio (1.05). No Michigan foundation company price is shown, because none of the companies we looked at published a price we could count. |
| Cement masons and concrete finishers, Michigan median | $59,860 a year | What workers are paid (BLS 2025 data via O*NET), not what you are charged. |
| Construction laborers, Michigan median | $49,590 a year | What workers are paid (BLS 2025 data via O*NET), not what you are charged. |
| Civil engineers, Michigan median | $92,100 a year | What civil engineers are paid, not what an engineer's report costs. No wage category covers foundation crews exactly. |
| Building permit, Ann Arbor | $15 application fee, then $100 plus $10 per $1,000 of project cost | Revised July 2025. Basement waterproofing is named. |
| Building permit, Grand Rapids | $79 for work valued at $1 to $1,000; $215 at $20,001 to $21,000 | FY2027 chart. No foundation line. |
| Building permit, Lansing | $175 for work valued at $4,001 to $10,000 | Schedule of July 1, 2026. |
How we estimate costs: the Estimated range row is a model, not a quote. It takes two published national ranges for this job (cost guides from third-party sites that we have not verified and do not cite) and multiplies them by Michigan's cement mason median wage ratio to the US (1.05, BLS 2025 data read through O*NET OnLine). No permit fee is added: the city permit rows below are shown as printed. The wage and permit rows are what workers are paid and what a city's own schedule charges, and neither is a price. Your soil, water and the repair method move a real quote well outside any range, so get an independent diagnosis first. We have not collected quotes, and we found no Michigan foundation company that publishes a price we could count. Full method. Prices as of Oct 19, 2026.
Why the diagnosis should come from someone with nothing to sell
In this trade the company that inspects often sells the fix, and a free inspection is a sales call with a measuring tape. You cannot tell from the visit whether the repair it proposes is the smallest one that works.
For anything structural, ask for a written report from a professional engineer who will not repair the house. A firm may offer engineering in Michigan only if at least two-thirds of its principals are licensees, so check any contractor that advertises in-house engineers on the LARA license search. Our engineer guide lists what to ask for.
Michigan does not require an engineer's stamp for ordinary foundation repair on a one or two family home, because state law exempts design of a detached house up to 3,500 square feet. A city may still ask for engineered drawings.
Who may repair a foundation in Michigan
There is no foundation repair license. LARA says every contractor offering work that totals $600 or more in labor and materials must be licensed, and a job split into smaller contracts does not qualify for the exemption. The holder needs a residential builder license or a maintenance and alteration license whose listed craft fits the work: carpentry, concrete, excavation, masonry and waterproofing a basement are the likely ones. Which craft covers a given job is our reading of the statute, so check the craft on the license.
Write the license number on the contract. An unlicensed contractor cannot sue you for payment or place a lien, and LARA says the state recovery fund for homeowners was abolished in 2010, so no state fund covers a bad job. The license guide shows the lookup.
Permits: what the code says and what your city decides
The base residential code requires a permit before anyone constructs, enlarges, alters or repairs a structure. Michigan's list of work that needs no building permit does not name foundation repair, though no state page says so in plain words, so your city's building official decides. Ann Arbor, Dearborn, Livonia, Sterling Heights and Warren print basement waterproofing as a permit item; Grand Rapids says renovations to an existing structure need a building permit and lists no foundation line.
If a repair adds or rebuilds a footing, Michigan's rule is 42 inches below actual grade, which the building official may modify. LARA says the 2015 Michigan Residential Code stays in effect under a July 2025 court order, so ask the city which edition applies.
When a foundation problem is an emergency
- A wall is visibly moving or has shifted since you last looked.
- A floor is dropping or a doorframe has pulled apart in days.
- Water is coming through a wall near the electrical panel. Do not step into that water.
- A crack that has not changed in months and lets no water in.
Answer these before anything else. They take about ten seconds.
- Is a crack horizontal, getting longer, or opening up week to week?
- Do doors or windows suddenly stick, or does a floor slope?
- Is water coming into the basement or crawl space right now?
- Is a wall visibly bowing or leaning?
- Is a gas or utility line affected, or does the structure feel unsafe? If so, leave the house and call 911.
Most foundation calls are not emergencies. Yes to the last three: get everyone clear of the problem, call 911 if the structure feels unsafe, and use the form with Emergency ticked. Yes to the first two: use the form and ask for an engineer's written report before any repair.
What to do before you call a foundation company
- Photograph each crack with a coin beside it, and mark both ends with a pencil and the date.
- Check that downspouts end away from the wall; the University of Minnesota Extension lists grading and gutters ahead of any drainage system.
- Ask the first company who diagnosed the problem and whether it would also do the repair.
Permits and licensing for foundation repair in Michigan
The base code requires a permit to repair or alter a structure, Michigan's exemption list does not name foundation work, and your city's building official makes the call. Ask the office before work starts, and ask the contractor to name the permit in the written price. A contractor charging $600 or more needs a LARA builder or maintenance and alteration license.
Ask for the contractor's license number and check it with your state licensing agency before you sign anything.

A tool for this job
Do I need an engineer first?
This is the trade where the company that finds the problem often sells the fix. Answer two questions and the tool tells you whether to call an engineer, get a second opinion, fix the water path or wait. It runs in your browser and asks for nothing.

How do they fix foundation problems?
The repair depends on the cause, and the cause has to be found first. Typical work is sealing or injecting a crack, bracing or rebuilding a wall, adding support under a footing, or fixing grading and drainage. We have no source that ranks these methods, so ask why the proposed one fits the cause.
How much does foundation repair cost in Michigan?
Our estimate for foundation repair in Michigan is $2,300 to $8,375 per project, built from national published ranges and adjusted for Michigan wages, because we have collected no Michigan quotes. A crack seal and a pier job sit at very different points in that range. Ask for an itemized price that names the method and the permit, and shows the license number.
Does foundation repair need a permit in Michigan?
Probably, but your city decides. The base code requires a permit to repair or alter a structure and Michigan's exemption list does not name foundation work, yet no state page we read says so in plain words. Ann Arbor, Dearborn, Livonia, Sterling Heights and Warren print waterproofing as a permit item, so call your building office before work starts.
Does a foundation repair company need a license in Michigan?
Yes, at $600 or more of labor and materials. There is no foundation category, so the company needs a residential builder license or a maintenance and alteration license with a craft that fits the work, which is our reading of the statute. Check the number on the LARA license search and read our license guide.
Do I need a structural engineer before foundation repair?
For anything structural, getting one first is the safest way to avoid paying for the wrong fix. The code calls for engineered design where walls face groundwater pressure or hold back more than 48 inches of unbalanced backfill. See the engineer guide.
