Repairing a cracked concrete patio typically costs $300-$2,000, with an average project near $900; extensive lifting or resurfacing can cost more. The final price depends on crack length and movement, patio size, repair method, access, and local labor rates.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Basic crack sealing | $150 | $450 | $900 | Small, stable cracks |
| Typical patio repair | $300 | $900 | $2,000 | Crack repair with limited patching |
| Resurfacing | $3/sq ft | $6/sq ft | $10/sq ft | Existing slab remains structurally sound |
| Slab lifting | $5/sq ft | $12/sq ft | $25/sq ft | Price depends on method and access |
| Full replacement | $8/sq ft | $14/sq ft | $20+/sq ft | Often includes demolition and new concrete |
What cracked patio repairs cost for common slab sizes
A contractor may charge $300-$900 to clean and fill a few stable cracks, while repairs involving several cracks, damaged edges, or minor surface patches commonly total $700-$2,000. For a 200-square-foot patio, resurfacing often runs $600-$2,000 if the slab is sound. Most homeowners pay about $5-$10 per square foot for a surface-focused repair, not a structural rebuild.
These are broad U.S. estimates for residential work. Small jobs may have a minimum service charge even when the crack is short. Assumptions: standard concrete, normal access, no major drainage correction, and midrange U.S. labor rates.
How crack filling, labor, and removal appear on a quote
Quotes separate materials and preparation from skilled labor, especially when cracks must be widened, cleaned, or stabilized before filling. Replacing a failed section adds demolition, hauling, base preparation, and new concrete. Ask whether the quoted repair addresses the cause of movement or only hides the visible crack.
| Quote item | Typical price | What it covers | Common cost driver |
|---|---|---|---|
| Crack filler and patch materials | $1-$4 per linear ft | Sealant, epoxy, or cement patch | Crack width and product type |
| Labor | $60-$100 per hour | Cleaning, routing, filling, finishing | Setup time and repair complexity |
| Surface grinding or prep | $1-$4 per sq ft | Removes loose concrete and improves bond | Coating or resurfacing requirements |
| Demolition and disposal | $2-$6 per sq ft | Breakup, loading, and concrete hauling | Thickness and equipment access |
| New concrete section | $6-$12 per sq ft | Base work, placement, and basic finish | Thickness, reinforcement, and finish |
Labor is often billed as a project amount rather than a visible hourly line. A small repair may still require 2-5 hours of setup and finishing, so the minimum charge can outweigh material costs.
Crack width, patio size, and settling change the estimate
Hairline cracks under 1/8 inch can often be sealed at the low end if the slab is stable. Cracks wider than 1/4 inch, uneven edges, or cracks that keep reopening may call for routing, epoxy, patching, or a structural assessment. A patio with more than 2 inches of vertical displacement may need lifting or replacement rather than filler alone.
Size also matters: a 100-square-foot slab may be practical to resurface, while a 400-square-foot patio increases material and preparation costs. Poor drainage, tree roots, a thin base, and freeze-thaw damage can add work beyond the visible crack. Movement and water problems are the strongest signs that a low-cost surface patch may not last.
Ways to lower the bill without hiding a recurring crack
Group several cracks or small patches into one visit to reduce repeated mobilization charges. Clear furniture and planters before the crew arrives, and provide photos and patio dimensions when requesting quotes. Compare at least three estimates that specify crack preparation, materials, repair depth, cleanup, and any warranty.
Choose a compatible repair product and finish rather than paying for a decorative coating the patio does not need. Avoid filling a moving or water-damaged crack before resolving the underlying issue. Keeping the repair scope to stable cracks and necessary surface work can prevent paying for premature resurfacing.
When sealing is cheaper than lifting or replacing concrete
Sealing is usually the least expensive choice for narrow, stable cracks that are mainly cosmetic or allow limited water entry. Epoxy or polyurethane injection may cost more but can suit deeper cracks where bonding or flexibility matters. Resurfacing costs more than basic filling and is best when the slab is sound but has widespread surface wear.
Slab lifting can restore a settled patio without removing the whole slab, but it may not solve a weak base or severe cracking. Replacement is more likely when multiple sections are broken, the slab moves substantially, or drainage and base failures are widespread. Repair is generally less costly upfront, but replacement may be the more durable option for badly failed concrete.
How long patio repair takes and what labor includes
Filling a few cracks may take 2-5 hours on site, while resurfacing a typical 200-square-foot patio can require one to two workdays, including preparation and application. Demolition and replacement often take two to four days of site work, followed by curing time before normal use. Weather and product instructions affect scheduling.
Contractor labor commonly falls around $60-$100 per hour, though many companies quote a fixed price. Extra preparation, tight access, hand demolition, or multiple visits can increase labor. Confirm when the patio can be walked on and when furniture can safely return.
Regional labor rates and access can shift patio repair prices
In lower-cost rural markets, straightforward crack repairs may run 10%-20% below national midrange estimates. Dense metro areas and high-cost coastal markets can be 15%-35% higher because of labor, disposal fees, and travel. These differences vary by contractor availability and local demand, not just geography.
Limited side-yard access may prevent equipment from reaching the slab and add hand labor or material handling charges. A nearby disposal site and clear equipment route can help keep demolition costs down. Request a site-specific quote because online per-square-foot rates may not include access or hauling.
Extra charges for drainage work, coatings, and disposal
Concrete removal and disposal can add $2-$6 per square foot when a failed section must be replaced. Correcting a downspout or minor drainage issue may add $100-$600, while substantial grading or drainage construction costs more. Decorative stains, sealers, or slip-resistant coatings can add roughly $1-$4 per square foot, depending on preparation and product.
Some contractors charge $75-$200 for an inspection or small-job minimum, with the fee sometimes credited toward approved work. Permits are not commonly required for simple crack filling, but replacement or changes to drainage may trigger local rules. Get add-ons and cleanup written into the estimate before approving the repair.
