TL;DR

Choosing a concrete contractor in Ohio is different from choosing a plumber or HVAC contractor because concrete is not state-licensed by OCILB. The trust check shifts to ACI (American Concrete Institute) certification on the crew, Ohio Secretary of State LLC filing, current insurance, ACI 332 residential standards, itemized written quotes, and sealcoating-scam discipline.

  • There is no statewide Ohio concrete license; do not let anyone pretend there is.
  • Verify ACI certification on the foreman, Ohio Secretary of State LLC filing, general liability insurance, and workers' compensation before any sub-base prep starts.
  • Insist on a 4-inch minimum slab for residential driveways with rebar or welded wire mesh and control joints cut at one-quarter slab thickness within 6-18 hours of the pour.
  • Walk away from door-to-door sealcoating crews, anyone who claims residential slabs don't need rebar, and any contractor who says "we don't need a permit" for structural work.
  • For foundation repair, structural slabs, retaining walls over 4 feet, and curb-cut work, confirm the permit with your local building department in writing before the pour.

Why this matters in Ohio specifically

Ohio's state contractor licensing system is asymmetric. Plumbing, HVAC, electrical, hydronics, and refrigeration are OCILB trades; concrete work is not. That means an Ohio homeowner cannot look up a concrete contractor in Ohio eLicense the same way they verify an HVAC license. The better check is a stack: ACI Certified Flatwork Finisher or ACI Concrete Field Technician credentials on the crew, American Concrete Institute certification references, Ohio Secretary of State LLC filing, current general liability insurance, workers' compensation, BBB profile, and local building-department permit pull history.

The Ohio Concrete Construction Association is the state trade body for ready-mix producers and concrete contractors. Member contractors participate in continuing education on ACI 318 (structural concrete), ACI 332 (residential concrete construction), and the NRMCA (National Ready Mixed Concrete Association) industry standards. Membership is not licensing, but it is a meaningful signal of professional engagement.

Freeze-thaw is the technical reality that makes Ohio concrete different from concrete in Tennessee or Texas. Northwest Ohio averages 50-70 freeze-thaw cycles per winter, and every cycle tries to pry water out of the pore structure of the slab. Properly air-entrained concrete (5-7 percent air for exterior flatwork), a low water-cement ratio, adequate cure time, and a penetrating siloxane sealer are the four levers a real contractor pulls to make a slab last 30+ years. The Ohio Department of Transportation Construction & Material Specifications (Item 499 concrete) is the authoritative document for what proper Ohio exterior concrete looks like, and many residential contractors quietly use it as their reference spec.

The National Ready Mixed Concrete Association certifies ready-mix producers and publishes the industry standard for mix design. Every truck of ready-mix that arrives on your job site carries a delivery ticket that documents the design strength, slump, air content, water added on site, and time of batching. A contractor who can hand you those tickets at the end of the job is a contractor running a real operation.

Door-to-door driveway sealcoating is the most common Ohio concrete-adjacent scam. Crews appear in summer, claim your driveway "needs" resealing every year, mix watered-down product, collect cash, and disappear. Real concrete sealing is on a 3-5 year cycle with a penetrating siloxane or silane product applied by a contractor who can name the manufacturer and product line. The same evidence stack — ACI, business registration, three insurance policies, written scope — is what protects you on a sealing job just as it does on a structural pour.

The 6-step process to choose well

  1. Step 1: Define the concrete job

    Measure before you call. Note the slab dimensions (length, width, thickness), document existing conditions with photographs from multiple angles, identify the finish you want (broom, stamped, exposed aggregate, polished), and decide on color or integral pigments. Confirm whether tear-out and haul-away of an existing pad is part of the scope, whether you need site grading or drainage work, and whether the slab is structural (supporting a wall, garage, addition) or non-structural (driveway, sidewalk, patio). The clearer the scope, the more comparable the quotes.

  2. Step 2: Verify ACI certification, business registration, and insurance

    Because Ohio does not state-license concrete work, verify the credentials that exist. Ask whether an ACI Certified Flatwork Finisher will be on the crew, and verify the credential reference. Confirm the company is an active Ohio LLC in good standing through the Ohio Secretary of State business filings portal. Ask for certificates of insurance: general liability and workers' compensation. For larger jobs, ask the insurance agent to send the certificate directly so you know it is current. The ProFix verification page explains the evidence stack ProFix tracks for trades that lack a state license.

  3. Step 3: Cross-reference with public records

    Look beyond review stars. ProFix profile pages line up business data, photos, evidence, and trust signals. For example, inspect an evidence page such as /pro/toledo-concrete-professionals-toledo/evidence before deciding how much weight to put on a concrete contractor's marketing. The Ohio licensing moat research explains why concrete contractors need a different verification stack than OCILB-licensed trades, and permits vs stars walks through what a real trust signal looks like.

  4. Step 4: Get 3 itemized quotes

    Concrete quotes are notoriously hard to compare because crews bundle scope inconsistently. For non-emergency work, request three written quotes through your own outreach or the ProFix lead form. Ask each contractor to separate demolition and tear-out, sub-base preparation and compaction, reinforcement type and spacing (rebar size + grid, welded wire mesh, or fiber addition), slab thickness, mix-design strength (3,000-4,500 psi for residential), air entrainment percentage, control joint plan, finish type, curing method, sealer product, and any optional add-ons. Three written, itemized quotes is the only way to make apples-to-apples comparison work.

  5. Step 5: Confirm permit if foundation or structural slab

    Permit thresholds vary by Ohio jurisdiction, but the general rule is: residential driveways and sidewalks on private property usually do not require a permit, while foundation repair, structural slabs supporting a garage or addition, retaining walls over 4 feet, and any work in the city right-of-way (curb cuts, sidewalk replacement in the public sidewalk corridor) almost always do. Confirm the permit requirement with your local building department in writing before the pour. Reference ProFix permit resources for jurisdiction-by-jurisdiction guidance.

  6. Step 6: Document the work

    Save the signed contract, all certificates of insurance, the ACI certification reference, Ohio Secretary of State filing reference, permit paperwork if applicable, the ready-mix delivery ticket from every truck, photographs of rebar layout before the pour, the control joint plan, finish samples, sealer manufacturer and product line, warranty terms, and the final lien waiver. If a settlement crack, finish defect, or warranty callback shows up later, the paperwork is the only thing that wins the argument.

Red flags to walk away from

  • Door-to-door driveway sealcoating crews who appear in summer with a vague pitch and pressure to sign before you compare three quotes — one of the most common Ohio home-services scams.
  • Refuses to list reinforcement (rebar, welded wire mesh, or fiber) in the written quote, or claims residential slabs do not need it.
  • No control joint plan, or proposes joint spacing wider than 3x the slab thickness in feet.
  • Claims "we don't need a permit" for a structural slab, foundation repair, retaining wall, or city right-of-way work.
  • Cash-only payment, no written contract, no certificate of insurance, no Ohio Secretary of State business registration on file.
  • Cannot produce an ACI certification reference for any crew member, and cannot name the ready-mix supplier or share the mix-design ticket.
  • Pours concrete on saturated, frozen, or uncompacted sub-base without addressing it in writing.
  • Promises a single-day pour-and-seal turnaround in October-November when overnight temperatures are below 40°F and proper curing is impossible.

Typical Ohio pricing

ProFix pricing uses the same structured cost-guide data that powers the public cost pages. Actual Ohio quotes vary by square footage, thickness, finish, reinforcement, sub-base condition, access, tear-out scope, and seasonal demand, but these ranges give you a sanity check before approving the work.

FAQ

Do Ohio concrete contractors need a state license?

No. Concrete is not one of the five OCILB-licensed trades in Ohio (those are plumbing, HVAC, electrical, hydronics, and refrigeration). Concrete contractors operate under general business registration with the Ohio Secretary of State, must carry insurance, and rely on ACI (American Concrete Institute) certification, Ohio Concrete Construction Association membership, NRMCA mix-design discipline, and local building-department permit history to establish trust. ProFix uses that evidence stack instead of a single state license number.

How thick should a residential driveway be in Ohio?

Four inches of properly mixed, properly cured concrete on a compacted aggregate base is the standard for a residential passenger-car driveway in Ohio. Bump to 5 inches if you regularly park heavy trucks, RVs, or trailers. Go to 6 inches at the apron where the driveway meets the street because that joint takes the most stress from refuse trucks and delivery vehicles. Anything thinner than 4 inches will crack early under Ohio freeze-thaw.

Concrete or asphalt for an Ohio driveway?

Both work in Ohio's freeze-thaw climate, but the trade-offs differ. Concrete costs more up front ($8-$15 per square foot vs $4-$8 for asphalt), lasts 30-40 years instead of 15-20, requires resealing roughly every 5 years instead of every 2-3, and handles oil leaks better. Asphalt is more forgiving of base movement and easier to patch. For a driveway you plan to keep for the life of the home, concrete usually wins on total cost of ownership.

Should there be rebar in my residential concrete driveway?

Rebar or welded wire mesh is the industry standard for a residential driveway in Ohio. ACI 332 (residential concrete) calls for reinforcement to control crack width when the inevitable shrinkage cracks form. A contractor who quotes a residential driveway with no rebar and no fiber-mesh substitute and no welded-wire reinforcement is cutting a corner you will pay for in 3-5 years. Ask exactly what reinforcement is in the proposal and at what spacing.

How often should I seal my concrete driveway in Ohio?

Seal a new concrete driveway about 30 days after the pour (long enough for initial cure, before the first winter), then reseal every 3-5 years depending on traffic, salt exposure, and product. A penetrating siloxane or silane sealer is more effective for Ohio's freeze-thaw cycle than a surface acrylic because it bonds inside the pore structure and lets vapor escape. Never let a sealcoating contractor talk you into resealing a concrete driveway every year — that is a sales pitch, not a maintenance plan.

Why is ACI certification important for an Ohio concrete contractor?

The American Concrete Institute publishes the industry standards every real concrete professional follows (ACI 318 for structural, ACI 332 for residential, ACI 301 for specifications). ACI also certifies individuals in flatwork finishing, concrete field testing, and concrete construction inspection. An ACI Certified Flatwork Finisher on the crew is the single best individual-credential signal that the contractor understands proper finishing technique, jointing patterns, and air-entrainment for Ohio freeze-thaw.

How wide and deep should control joints be in a residential slab?

Control joints should be cut to one-quarter of the slab thickness (1 inch deep for a 4-inch slab) and spaced no more than 2 to 3 times the slab thickness in feet (so 8-12 feet for a 4-inch slab). They should be cut within 6-18 hours of the pour while the concrete is still curing. A contractor who plans no control joints, or who spaces them every 20 feet, will produce a slab full of random cracks within a year.

Do I need a permit for a concrete driveway in Ohio?

Usually no for an in-kind replacement of an existing residential driveway on private property. Almost always yes for foundation repair, structural slabs supporting a garage or addition, retaining walls over 4 feet, and any work in the city right-of-way including curb cuts, sidewalk replacement, and apron work where the driveway meets the street. Always ask the contractor to confirm with your local building department in writing before the pour.
