Which Foundation Cracks Matter
Poured concrete pulls in a little as it dries, leaving fine lines in slabs, garage floors and stem walls. A hairline crack that keeps the same width for years is usually something to note and watch.
Other shapes are worth showing a specialist, calmly: a crack that climbs brick veneer in steps along the mortar, drywall split at an angle from the top corner of a door, or one line running through several floor tiles. Each can reflect uneven movement below the house, or be an old mark that stopped changing long ago. A crack wider than about 1/4 inch, one with an edge sitting proud of the other, or one that keeps lengthening belongs in your request.
Where sealing fits at all, injection is one method a specialist may suggest. Epoxy sets hard and can bond a dry crack that has stopped moving; polyurethane stays flexible and is often chosen where water seeps in. Many cracks call for nothing more than watching.
What Gets Done During Foundation Crack Repair
- Measuring each crack. The specialist notes width, length and direction, and whether both sides still sit flush.
- Sealing, patching or leaving it. A crack may be injected with epoxy or polyurethane, patched at the surface, or simply recorded.
- Water by the walls. Talk may turn to gutters, downspouts, grading or trees; any proposal is the specialist's call.

The Order of Work, Explained
- You describe the cracks. We read your note and hand it to one local foundation specialist, who replies if able to help.
- A look in person. If a visit happens, the specialist studies each crack, the doors and floors around it, and where water runs across the yard.
- A written plan, if any. It should name the method for each crack, any added work, the price and the warranty terms. If support work is included, ask whether a licensed professional engineer should review the plan.
- The permit question. If the plan goes past sealing to piers or other support, ask who handles any permit, and ask to see it. The City of Oklahoma City's permit page lists repairing or altering a structure among work that takes a permit, with no foundation-specific type; inside city limits, the City's Development Center can confirm what applies.
- The sealing itself. For injection, the repair crew cleans the crack, sets ports along it, seals the face and fills it.

What Foundation Crack Repair Protects
Sealing is meant to keep water, soil and insects out where a slab or wall has opened. Sealing does not hold the house up; support is a separate kind of work.
Some cracks start in the ground. Central Oklahoma lies in red Permian sandstone and shale country, as geologic surveys map it, and many of the region's clay soils formed from that red shale. Clay subsoil can take up water and release it slowly, so ground kept wet along one wall and dry along the next can let a foundation shift unevenly. A soil test or the specialist's visit is the way to learn what your lot holds.
Foundation Crack Repair Questions, Answered
Should a hairline crack in my slab worry me?
Usually it just deserves a record: date each end, photograph it with a coin for scale, and recheck after a long hot spell or a heavy soaking. In May 2015, the Oklahoma Mesonet reports, 19.48 inches of rain fell on Oklahoma City, its wettest month on record.
Will sealing a crack stop the house from moving?
No. Injection fills the gap and can help keep water out, but it changes nothing about what the soil below is doing. If the ground keeps shifting, a sealed crack can reopen beside the old line, which tells the specialist where the movement sits.
Is there a charge for using the request form?
Sending a request costs nothing and doesn't tie you to anything. One local foundation specialist receives it from us and gets back to you when it can help. Ask the specialist directly whether a visit or a written estimate carries a charge.
What should I check before anyone seals a crack?
Oklahoma issues no state license for foundation work, even for one sealed crack. Inside Oklahoma City limits, the City's residential building contractor registration applies when the work needs a building permit, so ask and confirm with the City; elsewhere, ask that city's office. A CIB-licensed tradesperson handles any plumbing, electrical or mechanical piece.
