How to choose a foundation repair company in Michigan
A crack in a basement wall or water on the floor after a heavy rain is stressful, and the first company you call may not be the right one. Some of the companies listed here mostly keep water out. Others mostly fix walls and foundations that have moved. Many do both. This guide covers what to look for before you sign anything.
Know which problem you have
Water coming in is a waterproofing job. That usually means drain tile, a sump pump, sealing cracks or encapsulating a crawl space. Walls that bow, floors that sag or doors that stick point to a structural problem. That calls for wall anchors, braces, piers or other foundation repair. A good company will tell you which one you have after an inspection, and many listed here say they offer that inspection for free.
Much of southeast Michigan and the Saginaw Bay area sits on old lake bottoms. Michigan State University describes these lake plains as flat land filled with clays and silts. Heavy rain has also become more common. Michigan's yearly total has ranged from 22.7 inches to 41.8 inches, and the state recorded the most 2-inch downpours in the years 2015 to 2020.
Ask about the license
Michigan's Occupational Code names waterproofing a basement as one of the trades a residential builder or maintenance and alteration contractor license covers. Foundation repair is not named on its own list, but the residential builder license covers repair and alteration of a home. Ask for the license number, and check it with the state before you pay a deposit. Under Michigan law, an unlicensed contractor cannot sue to collect payment or put a lien on your home for work that needed a license. The listings on this site show whether a company states a license on its own website. This site does not check licenses.
Ask about permits and digging
Michigan requires a building permit before a building is altered. Ask the company who pulls the permit and whether your city will inspect the work. Your city's building department can tell you what applies to your job. If the work means digging outside, such as exterior waterproofing or drain tile, someone has to contact MISS DIG at 811 at least 72 hours, and no more than 14 days, before digging starts.
How to read a listing
Each listing shows the services a company names on its own website: foundation repair, basement waterproofing, bowing wall repair, piers, crack repair, crawl space work, sump pumps, drain tile, concrete lifting and egress windows. It also shows whether the company mentions a free inspection, financing, a license or a warranty. A service under "No information yet" means the company's site does not say. It does not mean the company does not offer it. Call and ask.
What to ask on the first call
Ask what they think is causing the problem and how they know. Ask what the warranty covers, whether it is in writing, and whether it transfers if you sell the house. Ask who does the work, their own crew or a subcontractor. Get at least two written estimates that describe the same scope of work, so you can compare them line by line.
