Poured Walls Versus Block Walls
Poured concrete shrinks slightly as it cures, so thin vertical or diagonal cracks can appear in walls of any age, many of them bone dry. If one starts passing water in wet weather, injection is the common remedy: small ports are fixed along the line from the basement side, and epoxy or polyurethane is pumped in until resin fills the crack from face to face.
Block and brick crack along the mortar instead, often in a stair-step pattern, and old joints can soften and crumble. Resin would simply drain into hollow block cores, so the usual fix is repointing: loose mortar is cut out and fresh mortar packed in. Older brick foundations can need that work across a whole wall. Dayton has a large stock of pre-1940 basements (36.7% of its homes date to 1939 or earlier, per Census survey data), while newer homes, including many in Vandalia, OH, can be built differently.
Winter freeze-thaw can work an open crack wider, and the slow clay-loam subsoil of west-central Ohio's glacial till can stay wet into spring and press on a wall. A sideways crack, one that keeps lengthening, or a wall bowing inward is worth having looked at soon: a reason to ask, not a verdict.
Where Foundation Crack Repair Fits
- Leaking poured crack. Epoxy, which sets rigid and bonds both faces, or polyurethane, which keeps some give, injected from inside.
- Stair-step joints. Worn mortar in block or brick raked out and replaced.
- Damp but sound. A surface sealer can ease dampness, though it won't stop water under pressure.
- Sideways crack or inward bow. Worth a professional look soon, whatever the wall is made of.
- A crack that grows. Pencil a tick and date at each end; a few months will show whether it is lengthening.
Costs to Expect
| Cost row | Figure | Source (year) |
|---|---|---|
| Typical basement waterproofing project | about $3,000 to $10,000 (average about $5,000) | Fixr national (2026) |
| Interior perimeter drain, per linear foot | $40 to $120 | Fixr national (2026) |
| Sump pump installation | $600 to $2,500 | Fixr national (2026) |

| Waterproof paint or sealant, per sq ft | $1 to $8 | Fixr national (2026) |
With one or two cracks, the injection row is the one to watch. It is a national Fixr figure, since no Dayton or Ohio source lists crack-repair prices, and it isn't a price from this site. Repointing, wall bracing and outside digging have no sourced figure, so ask for each to be priced on its own line. The cost guide explains what else shifts a total.
The Work, Start to Finish
- Measuring each crack. Contractors typically photograph it, note its width, length and direction, and look for staining.
- Choosing the repair. The wall material largely settles injection versus repointing; a sideways crack or bowing wall may need more than a seal.
- Permits. The City of Dayton requires a building permit for structural repairs, issued by its Division of Building Services, 371 W. Second St., 937-333-3883. Riverside, OH and Trotwood, OH homeowners get building permits through Montgomery County, 937-225-4622, and other towns through their own offices. The contractor works out which apply and who takes them out.
In Oakwood, OH, an egress window or outside dig may first need a word with the City's zoning office, (937) 297-2920.
Less Hassle, Clearer Answers
Nobody contacts you unless you send the form, and then only one independent local contractor. As a referral and advertising service, this site never examines a wall, judges a crack or prices a repair; a contractor may pay it a flat advertising fee (on a free trial for now), and you pay it nothing.
Ohio has no state license for waterproofing or crack sealing, so check what you can. For any plumbing, wiring or HVAC piece of a Dayton job, Building Services can confirm City registration of the tradesperson. Request liability and workers' compensation certificates and several recent customers to talk to.
Common Questions
Should I worry about a thin crack that stays dry?
Usually not right away. Many hairline cracks in poured walls come from curing and stay stable for years, so watching is enough. If one seeps after storms or grows season to season, injection is the usual answer; describe what you've seen in the form.
Epoxy or polyurethane: which should I expect?
That depends on the crack. Epoxy cures hard and can knit a dry, stable crack together; polyurethane foams up and stays pliable, so it often handles damp or shifting cracks better. Ask which one is planned and why, and get the warranty in writing, including whether it transfers to a later owner.
What if a repair goes wrong?
Put the problem to the contractor in writing and keep copies; consumer complaints go to the Ohio Attorney General's Consumer Protection Section. A contract signed in your home generally carries a right to cancel until midnight on the third business day, and the contract should spell out the steps.

Find Out What Crack Repair Costs
For each crack, note which wall it's on, about how long it runs and whether water comes through; a photo with a tape measure in the frame helps. Once the form is sent, one independent contractor gets in touch, sees the wall in person and gives its own written estimate. Going ahead is your call. The short form below has room for those notes.
