How Wall Cracks Get Repaired
Poured concrete shrinks while it cures, leaving thin vertical or slightly angled lines. The standard fix is injection: small ports are fixed along the crack and resin is pressed in until the gap fills through the wall.
Block and stone crack along their mortar, block in a stair-step line and stone through joints that turn to sand. Resin is wasted in hollow cores and loose rubble, so the usual answer is repointing: raking out weak mortar and packing in new. About 48% of the City's homes date from before 1940 (Census survey data), so older stone and block foundations are common.
Most cracks only admit water. One that runs sideways, keeps widening or comes with a bowing or leaning wall is worth having looked at soon. Freeze-thaw cycles and a soggy spring can open a gap a little each year, so dated pencil marks at both ends help show change.
Inside the City, foundation, excavation and retaining-wall work generally needs a PLI permit, and a steep or landslide-prone lot may need geotechnical review; the contractor confirms permits with PLI. City Zoning (412-255-2241) answers questions about hillside overlay areas.
One insurance note, for information only: according to the state Department of Environmental Protection, standard homeowners coverage typically leaves out mine subsidence, and the department offers separate Mine Subsidence Insurance. Its map checks an address, and its line is 1-800-922-1678.
What Gets Done
- Hairline lines in poured walls. Resin injected from the basement side, often in one visit.
- Stair-step cracks in block. Fresh mortar in the opened joints.
- Sandy mortar in stone. New mortar packed where the old joints have worn away.
- Cracks fed by runoff. Sealing the crack and redirecting the downspout or grade that feeds it.
- A crack running sideways. Horizontal lines in any wall type merit a closer look soon.
- Growth past your marks. Note it, with dates, in your request.

For one or two cracks, watch the injection row, a 2026 national per-crack figure from Fixr, not this site's price. Repointing, bracing and hillside digging have no sourced number; ask for each as its own line. The cost guide walks through what moves a local total.
What to Expect, Step by Step
- Photos with a tape measure. Date each one so change is easy to spot.
- Questions about the wall. Poured, block or stone, when water appears and where downspouts drain.
- A plan in writing. Each crack, its repair method, the material and the warranty terms.
- Permits. Inside the City, the permit holder should be the contractor, which on rental or investment property also needs a PLI General Contractor license. Suburbs have their own offices.
- A follow-up look. Check the repair after heavy rain and again after winter.
What You Get by Asking Here
You describe the crack once; measuring and pricing belong to the contractor. This site only refers. It is not a contractor, holds no Pennsylvania home improvement contractor registration, never visits a house and never quotes or signs for work. Contractors may advertise here, free during a trial; homeowners pay nothing and get nothing. Look up the PA number printed on the estimate through the Attorney General (1-888-520-6680 or online).
Quick Answers
Should every crack worry me?
No. Thin vertical lines in poured concrete usually come from shrinkage, and many never do more than let in a little water. The ones worth a prompt look run horizontally, keep getting wider or sit in a wall that has begun to bow.
Can an old stone foundation be injected?
Not well, as a rule. Rubble walls have uneven joints and hidden voids that soak up resin without closing the gap. Repointing the worst joints, often with an inside drain to relieve water pressure, is the more common route locally.
Epoxy or polyurethane: which is better?
Each has a job. Epoxy cures rigid and glues the two faces together, so it fits a crack where strength matters; polyurethane foams and stays slightly flexible, so it mostly serves to stop water. Expect the estimate to state which resin goes into each crack.
Does crack repair in Pittsburgh need a permit?
That turns on the scope. Foundation work is not on PLI's list of jobs that skip a permit, and bracing or digging outside adds review, especially on a steep lot. The contractor checks with PLI before starting; suburbs set their own rules.
