Cracks, spalling, faded sealer, and worn surfaces don't always mean your patio slab has failed. Detroit Concrete assesses the base, patches what is broken, and resurfaces tired-looking concrete when the structure is still sound. We give you a straight answer on whether repair saves money or if replacement is the right call. Every assessment comes with a free written estimate.
A patio that looks rough on top is not necessarily a patio that needs to come out. The concrete slab underneath is often still level, still bonded to the house, and the visible problems are surface-level: cracks that haven't widened, spalled edges at the corners, sealer that has worn away, weeds pushing through joints.
These issues respond to concrete patio repair. Cracks get sealed to stop water from freezing inside them. Spalled sections are cut out cleanly and patched back to match the surrounding slab. When the whole surface looks tired, a thin overlay goes down and gives the patio a fresh, uniform finish in a day or two.
The line between repair and replacement is when the base itself has failed. Slabs that are heaving, settling away from the house, or pulling apart at the joints mean the ground underneath has shifted. That is when a new concrete pour is the honest answer. We walk your patio, tell you which side of that line you are on, and quote accordingly.

The repair sequence
How Patio Repair and Overlay Gets Done in Detroit
Inspect the slab and base
We check for level, cracks, spalling, and any movement that signals base failure. This tells us whether repair is viable or if the slab needs to come out.
Saw-cut and remove damage
For localized spalling or cracks, we cut clean edges around the bad area with a concrete saw, remove the broken material, and expose sound concrete underneath.
Prep and bond the patch
The prepared area is cleaned, primed if needed, and filled with repair mortar that bonds to the existing slab. Reinforcement is added for larger patches.
Finish and seal the surface
Patches are textured to match the surrounding concrete. Full resurfacing covers the entire slab in one continuous layer. Sealer is applied after cure to protect against water and weather.
Overlay and protection
How Resurfacing Refreshes a Tired Patio
When cracks and spalling are scattered across the whole patio, spot-patching leaves a patchwork look. Resurfacing is the better choice. A thin concrete overlay is applied over the prepared slab and creates a fresh, uniform finish that reads as a new patio without the cost and time of a tear-out.
After repair or resurfacing, concrete sealer closes the surface against water, salt, and freeze-thaw cycles. If the assessment shows the slab really cannot be saved, we offer plain concrete, exposed aggregate, and stamped patio options for a full replacement.
Repair vs replace, cracks, resurfacing and what is honest to fix in Detroit.
If the cracks are surface-only and the slab still sits level against the house, repair makes sense. If the slab is heaving, settling or pulling away from the house, the base has likely failed and a new pour is the honest answer.
Yes. We saw-cut clean edges around the spalled area, prepare the base, and bond a patch into the sound concrete. Done with the right mortar and prep, a patch holds as well as the original.
Resurfacing lays a thin overlay across a prepared slab when the structure is sound but the surface is cosmetically gone. It gives the whole patio a fresh, uniform look at a fraction of the cost and time of a tear-out.
Patches into existing concrete are visible up close, but resurfacing covers the whole slab in one go and reads as a new finish. Either way, sealing afterwards keeps the result protected for years.
Most localised repairs are done in a day. A full resurface usually wraps in a day or two, with a cure window before furniture goes back. We give you the exact timeline on the assessment.
Homeowner reviews
What Detroit Homeowners Say About Their Patio Repairs
Resurfaced our old broom-finish patio instead of tearing it out. The new top reads as a brand-new patio and we used the slab through the summer.

★★★★★
Spalled corners at the steps, patched cleanly and colour-matched. No more catching shovels on the broken edges, and the seam is barely visible.
M. P.
Ann Arbor
★★★★★
Honest that the back half of the patio had base problems and the front half was sound. Replaced the back, repaired the front, exactly what we agreed on.
A. Q.
Dearborn
★★★★★
Cracks sealed before they could grow. The seal is back on the whole patio and the slab looks easily a decade younger than it did before.
