Hairline, Stair-Step or Horizontal?
In poured concrete, hairline cracks running straight up or at a slight angle usually date from curing, when the fresh concrete shrank. They are commonly sealed by injection: small ports go along the line, and epoxy or polyurethane is pushed in until the gap fills through the wall.
Concrete block breaks along its mortar, so its cracks climb in a stair-step pattern. Injected material can vanish into the hollow cores, which is why repointing, often with drainage to relieve the water pressing on the wall, is the more usual approach.
Stone and brick behave differently again. More than 4 in 10 homes in the City of Minneapolis date from 1939 or earlier (Census survey data), and Longfellow's housing is marked by 1920s bungalow-style homes (Macalester, 2012). Older stone, brick and clay-tile foundation walls seldom crack the way concrete does; instead the mortar softens and joints open. The usual remedy is repointing in a mix soft enough for old masonry.
Cold weather adds a twist. Water sitting in a crack can freeze and expand, so repeated freeze-thaw cycles can widen a line a little each winter. Wet, clay-heavy soil can push on a wall, frost can add pressure near the top, and spring snowmelt then feeds the same openings.
A long horizontal crack, a wall bowing inward or a crack whose sides no longer line up is worth having looked at soon, as is any crack that keeps getting wider. Pencil the date at each end to track change.
Common Situations
- A hairline in poured concrete. Typically injected from the inside in one visit.
- Stair-step cracks in block. Repointing open joints, often alongside drainage.
- Soft, sandy mortar in stone or brick. Raking out worn joints and refilling them with a compatible mix.
- A crack that seeps only in the thaw. Sealing it, then moving snow piles and downspouts away from that wall.
- A long sideways crack or an inward bow. Worth a contractor's look before long.
- A line that keeps growing. Mention the dated pencil marks in your request.

A typical crack job lands on the injection row. Like the others, it is a 2026 national range from Fixr, with no Minnesota source behind it and no price from this site. Repointing, wall bracing and other structural repair have no sourced number here, so ask to see each as its own line. The cost guide covers what pushes a total higher.
From First Visit to Finished Job
- Photos beside a tape measure. Shoot each crack with a ruler in frame.
- The visit. The contractor usually asks what the wall is made of and when water appears.
- The method in writing. A DLI licensee's contract must be written, signed and dated, describing each repair, the specific materials and the total price or how it is figured, with the license number and a free signed copy for you.
- Permits. Structural repair and excavation generally require a building permit from the city the home is in: Minneapolis Development Review (612-673-3000) for City addresses, or a suburb's own permit office. The contractor confirms which apply.
- After the next thaw. Check the repaired line for damp.
What Makes This Easier
One description of the crack leads to one contractor's visit, explanation and written price. Behind this site is only a referral and advertising service with no DLI license; it never visits, diagnoses, prices or contracts for work. A flat advertising fee may come to it from the contractor, while homeowners pay it nothing and get nothing from it.
Before you sign, check the business on DLI's license and registration lookup or at 1-800-657-3944, and find out if it carries a license or just a registration. A licensee's work can open the Contractor Recovery Fund, up to a limit set in state law, after a court judgment for certain losses; DLI says to apply within two years. DLI also advises a modest deposit, never full payment before work begins.
Crack Repair Questions, Answered
Does every crack need fixing?
No. Thin vertical lines in poured concrete often go back to curing and may let in a little water or none. The ones worth a look soon run long and horizontal, keep widening, have shifted edges or come with a wall leaning inward.
Epoxy or polyurethane?
Epoxy cures rigid and glues the two sides together, a fit where strength counts. Polyurethane foams and stays a bit flexible, a frequent pick for keeping water out. Have the material named in the contract.
Why do cracks seem worse in spring?
Frost and meltwater arrive together, so a line that was dry in January can seep by April.
