It usually starts small. A crack in the basement wall that seems longer than it was last fall. A door upstairs that suddenly sticks. Water on the basement floor every spring when the snow melts. Or an inspector writes “structural concern” in a report, and the buyer you thought you had is gone by the end of the week.
Foundation problems scare buyers more than almost anything else in a house, and the fear is often bigger than the problem. Before you spend money or make a decision, it helps to know what you are actually dealing with and how it affects a sale. This article is a general overview. A licensed structural engineer, your city, and a Minnesota real estate attorney are the authorities on your specific house.
Much of the Twin Cities housing stock is old. Many homes in Minneapolis and St. Paul were built before World War II on stone or brick foundations, and many postwar ramblers and suburban homes sit on concrete block. Both can hold up for a century, and both have weak points.
Minnesota winters are hard on basement walls. Saturated and frozen soil pushes sideways against the wall, year after year, and block walls in particular can crack and start to lean inward. Clay soils in parts of the metro swell when wet and shrink when dry. Clogged gutters, short downspouts, and yards that slope toward the house send snowmelt straight at the foundation. That is why so many foundation problems show up, or get worse, between late fall and spring.
Not every crack is a structural problem. As a general rule, these are usually less concerning:
Hairline cracks in poured concrete that run up and down, are not getting wider, and do not leak.
White, chalky residue on the wall. That is mineral deposits left by moisture. It means water is getting in, not that the wall is failing.
These are the signs that usually deserve a professional look:
A horizontal crack along a block wall, especially near the middle of the wall’s height.
Stair step cracks that follow the mortar joints in a block or brick wall.
A wall that bows inward or has shifted at the top or bottom.
Cracks that are wider at one end or keep growing.
Sloping floors, sticking doors and windows, or new gaps at the trim upstairs.
Crumbling mortar or loose stones in an older stone foundation.
Most foundation repair companies offer free estimates, but they are in the business of selling repairs. A licensed structural engineer charges a fee and has nothing to sell you. The engineer can tell you what is wrong, how serious it is, and what kind of repair actually fits. That report is useful no matter what you decide: it lets you compare contractor bids, and it gives buyers and lenders something concrete instead of guesswork.
If you do repair, ask whether your city requires a permit. Many cities do for structural work, and a permitted, documented repair is far easier to sell than one with no paper trail.
Costs depend on the house, the soil, access, and how far the problem has progressed, so only an in person evaluation gives you a real number. As a rough sense of scale, sealing a minor crack can cost a few hundred dollars. Bracing a bowing wall with straps or anchors typically runs several thousand dollars. Interior drain tile and a sump system can cost several thousand dollars or more. Excavating and rebuilding a wall, or installing piers under a settling foundation, often reaches the tens of thousands.
Then add what the repair disturbs: finished basement walls, flooring, landscaping, decks, and driveways. Exterior excavation also gets harder and more expensive once the ground freezes, so some repairs end up waiting for spring.
Do not count on homeowners insurance to cover it. Most standard policies exclude settling, cracking, earth movement, and gradual seepage. Damage from a sudden covered event can be different, so ask your insurance agent, but plan as if the cost is yours.
Disclosure. Minnesota requires sellers to disclose known problems that could significantly affect a buyer’s use or enjoyment of the house. Patching a known problem does not make it disappear from the disclosure, and fresh patching with no paperwork can look like an attempt to hide something.
Inspections. Nearly every buyer with a mortgage gets an inspection, and foundation findings are a common reason deals get renegotiated or fall apart.
Lenders. An appraiser can make a loan conditional on structural repairs being completed before closing, or the lender can ask for an engineer’s report. Many financed buyers simply cannot close on a house with an unresolved foundation problem.
City inspections. Minneapolis, St. Paul, and several suburbs require a truth in housing or point of sale evaluation, and those evaluations look at the foundation. Depending on the city, required repairs may need to be finished before closing or formally taken on by the buyer, sometimes they are accompanied by an escrow agreement.
The market. There are noticeably more homes for sale in the Twin Cities this fall than a year ago, homes are taking longer to sell, and mortgage rates remain well above where they were last year. Buyers with options tend to skip the house with the cracked basement wall.
Repair it, document it, then list. This makes the most sense when the repair is moderate, you have the cash and the time, and the rest of the house is in good shape. Keep the engineer’s report, the permit, and any transferable warranty. Buyers pay more for a documented fix than for an unknown. You are still fronting the cost, though, and you may not get it all back in the sale price.
List it as is with full disclosure. You avoid the repair, but expect buyers to price in the worst case plus a discount for the hassle. Many financed buyers will not be able to close, and offers that come in may fall apart after inspection or appraisal. If the house also needs other work, our post on selling a house that needs major repairs covers how to decide whether fixing it pencils out.
Sell to a cash buyer. We will be direct about this: a cash offer will be lower than what the house would bring after a professional repair. In exchange, there is no lender to satisfy, no appraisal, no inspection renegotiation, and no repair to manage through a Minnesota winter, and you choose the closing date. Compare what you would actually walk away with: the repair cost, the disruption, the price reduction buyers will still ask for, commissions, and the carrying costs of a long listing. Our post on waiting for spring to sell breaks down what those months cost.
