TL;DR
- Tap to call from any device — every listed pro has a real, working dial-direct number.
- License-verified pros only — we check Ohio state licensing (where the trade requires it) before the pro lands on this page.
- Statewide coverage across all 88 Ohio counties, including Toledo, Cleveland, Columbus, Cincinnati, Dayton, Findlay, Akron, Youngstown, Canton, and Lima.
When this is an actual emergency
Not every concrete contractor problem is a 2 AM call. These are the situations where waiting until morning costs more in damage than the after-hours premium costs in dispatch.
- Visible sinkhole or significant ground subsidence near foundation, driveway, or sidewalk.
- Foundation crack actively leaking water during a storm event.
- Large slab heave that has lifted a sidewalk, step, or porch out of safe walking grade.
- Garage-floor slab failure under a parked vehicle.
- Retaining wall bulging or tilting after heavy rain — collapse risk to property or neighbors.

What to do while you wait
Four practical steps for the 30–60 minutes between calling and the truck arriving. Most of the damage in an emergency happens in this window — small actions matter.
- Rope off any sinkhole, heaved slab, or tilting wall — slip and fall risk is the immediate hazard.
- Move vehicles, equipment, and outdoor furniture off any failing slab.
- Take photos with reference objects for scale — concrete failures often expand fast under continued weather.
- Tarp any actively leaking foundation crack to slow water entry; do NOT seal it yet — repair requires dry surface.
When to call the utility company first
If a sinkhole opens within 30 feet of a utility line — gas, water, sewer, or buried electric — call the utility first, not the concrete contractor. Columbia Gas (1-800-344-4077) for any gas line concern, your city water department for water-main proximity, 811 (always free) to check buried utility marks before any excavation.
Honest cost expectations for after-hours
Emergency concrete dispatch is rare and runs $200–$400 for a same-day site visit. Repair pricing depends on permanent-fix scope: foundation crack injection $400–$1,200, sinkhole grout fill $1,500–$5,000, sidewalk slab replacement $400–$1,200 per panel, retaining-wall repair $2,500–$15,000. Concrete pours require 50°F+ ambient temperature for 3+ days — winter emergencies usually get a temporary safe-out and a spring repair scheduled.
Reputable Ohio concrete contractors disclose the after-hours premium BEFORE the truck rolls. A pro who refuses to quote the dispatch fee or service-call fee on the phone is the wrong choice for an emergency — call the next pro on your shortlist instead.
Frequently asked — emergency concrete contractors
Is concrete state-licensed in Ohio?
No, concrete is not state-licensed. Substitute trust signals are ACI and NRMCA certifications, workers' comp coverage, $1M general liability, and verifiable permit pulls where a job touches right of way, retaining walls, or structural foundation work.
Why won't they pour concrete in winter to fix this emergency?
Pour temperature must stay above 50°F for at least 3 days for proper cure. Ohio winters drop below that range often. A reputable shop will safe-out the hazard now and schedule the actual repair when conditions allow — the alternative is a pour that fails in the first freeze-thaw cycle.
Will my homeowners insurance cover a sinkhole?
Standard Ohio policies usually exclude earth movement. A sinkhole rider is a separate add-on. If the sinkhole is from a water-line break (covered) versus natural settlement (excluded), the carrier's adjuster will decide — document everything.
How do I know the contractor's emergency price is fair?
Get two estimates whenever the situation allows, even on emergency work. Ask for the line-item breakdown: site visit, temporary stabilization, materials, labor, permits. A single all-in number on emergency concrete should still itemize on the invoice.
Should I call the city instead of a private concrete contractor?
If the failure is in the city right of way (sidewalk slab, curb, public alley), call the city first — they may own the repair. If it's on private property past the right of way line, it's your contractor's job.
