Permit requirements for concrete work vary by municipality, but a new driveway apron connecting to a public street usually requires a permit and sometimes a city inspection. A standalone backyard patio typically doesn't need one unless it affects drainage or property setbacks. Checking with the local building department before pouring avoids having to redo work that fails inspection.

The actual pour and finishing for a typical driveway or patio takes one to two days, but the full project timeline includes excavation, forming and base prep beforehand. Concrete needs about 24 to 48 hours before it can be walked on and roughly 7 days before light vehicle traffic. Full cure strength takes about 28 days, though the surface is functional well before that.

Concrete projects can be adjusted to fit a budget by changing slab thickness, reinforcement type, or finish, since a plain broom finish costs significantly less than stamped or exposed aggregate concrete. Reducing square footage or phasing a project, doing the driveway now and a patio later, is another common way to control cost. Discussing budget upfront lets a contractor recommend the best trade-offs.

Reputable concrete contractors typically offer a workmanship warranty covering cracking, settling or finish defects for a set period, often one to five years, separate from any material warranty. Concrete does develop hairline shrinkage cracks as a normal part of curing, which isn't usually covered since it's not a workmanship defect. Ask what specifically is and isn't included before signing a contract.

On most residential concrete jobs, a crew lead or foreman is the main point of contact on site day to day, handling scheduling questions and any changes that come up. The person who gave the original quote is often available for bigger decisions, like a change in scope. Getting a direct phone number for the job site contact before work starts is standard practice.

Residential concrete work in colder climates should use air-entrained concrete, which has microscopic air bubbles mixed in to let the slab expand and contract without cracking during freeze-thaw cycles. Standard mixes run around 3,000 to 4,000 PSI for driveways and patios, with higher strength mixes used for garage floors or areas with heavy vehicle loads. Fiber mesh is often added to reduce shrinkage cracking during curing.

Access to a driveway is typically blocked from the demo and pour through the initial cure period, usually about a week before it can handle vehicle weight again. Parking on the street or in a neighboring spot during that window is the usual workaround. The rest of the yard generally stays usable unless equipment needs to cross it to reach the work area.

Moving vehicles, patio furniture, and anything breakable away from the work area before a crew arrives speeds up the job and avoids damage. Marking or noting the location of buried sprinkler lines, invisible fencing, or septic components helps avoid costly surprises during excavation. Clearing a path for equipment access, especially for backyard pours, also matters.

Unexpected finds during excavation, like old buried concrete, tree roots, or soft unstable soil, usually mean adjusting the base prep or removing the obstruction before pouring can continue. This can add time and cost to a project, which is why a reputable contractor communicates the issue and gets approval before proceeding rather than absorbing it silently into the final bill. Soft or expansive clay soil sometimes calls for extra sub-base material to keep the slab from settling unevenly.

New concrete needs to cure for at least 7 days before heavy use and about 28 days before full strength is reached, so vehicle traffic and heavy furniture should wait. Sealing the surface every two to three years helps protect against water intrusion and salt damage, especially important in climates with winter road salt. Avoiding deicing salt on new concrete for at least the first winter reduces the risk of surface scaling.
