When localized patio repair may fit
Localized repair may fit a stable crack, broken edge, shallow spall, or defined damaged section when the nearby concrete remains sound. Preparation must reach a stable perimeter and provide suitable geometry for the selected repair material.
A repair will remain visible when the old concrete has different color, texture, aggregate, or weathering. Finish expectations belong in the written scope.
When resurfacing may fit
Resurfacing may fit a patio with broad wear or appearance concerns when the slab remains sound and stable. Existing coatings, sealers, contamination, moisture, cracks, joints, and drainage must be addressed as part of system selection and preparation.
A thin surface system does not stabilize movement, rebuild failed support, or correct deep deterioration. Unsound areas may need repair or replacement first.
When replacement becomes more practical
Partial or broader replacement becomes more likely when panels are moving, badly broken, holding water, undermined, broadly delaminated, or covered with repeated failed repairs.
Thresholds, doors, drains, walls, posts, landscaping, and access can affect how much concrete can be changed and whether a practical slope can be built.
What to include in a patio review
Photograph the entire patio, every damaged area, doors and thresholds, drains, low points after water exposure, coatings, and access for removal. Describe what changed over time and whether any section rocks or changes height.
That context supports a condition-based choice among crack repair, localized patching, resurfacing, partial replacement, and broader replacement.
