Concrete Crack Repair Pricing: What Contractors Should Charge
Concrete crack repair costs $150-$800 per crack depending on type and method. Epoxy injection for structural cracks runs $250-$600 per crack. Polyurethane injection for water-stopping costs $200-$500. Routing and sealing surface cracks costs $3-$8 per linear foot. Polymer patching for cosmetic repairs runs $100-$250 per crack. Carbon fiber staple reinforcement adds $150-$300 per staple.
Concrete crack repair is a high-demand, high-margin service that every concrete contractor should offer. Cracks are inevitable in concrete work, and homeowners actively search for repair solutions. A single afternoon of crack repair work can generate $1,000-$3,000 in revenue with minimal material costs. This guide covers pricing for every crack repair method, from cosmetic patching to structural epoxy injection.
Understanding Crack Types and Their Repair Costs
Not all cracks are the same, and the repair method (and price) depends on crack type and cause. Hairline cracks (less than 1/16 inch) are cosmetic — they result from normal shrinkage during curing and do not affect structural integrity. Repair with polymer-modified surface filler at $100-$200 per crack or $1-$3 per linear foot. Structural cracks (1/16 to 1/4 inch, often through the full slab depth) indicate loading or settlement issues — repair with epoxy injection at $250-$600 per crack. Active cracks (still widening over time, identified by monitoring crack gauges) require flexible repair materials like polyurethane injection at $200-$500 per crack, as rigid epoxy will crack again alongside the original joint. Pattern cracking (map cracking across a wide area) indicates mix issues or premature drying — these require overlay or resurfacing rather than individual crack treatment at $3-$8 per sq ft for the affected area. Always diagnose the crack type before recommending a repair method. The diagnostic expertise is part of your value — charge for inspections ($100-$300) or build the assessment time into your repair pricing.
Epoxy Injection Repair Pricing
Epoxy injection is the gold standard for structural crack repair, welding the concrete back to its original strength. Price: $250-$600 per crack for typical residential cracks (3-8 feet long). The process involves: cleaning the crack of debris and contaminants, installing injection ports at 6-12 inch intervals along the crack ($2-$5 per port), sealing the crack surface between ports with epoxy paste ($15-$30 per crack), and injecting structural epoxy under low pressure through each port ($30-$80 per crack for epoxy material). Total material cost per crack is $50-$120, making labor and expertise your primary value. A skilled technician can complete 3-5 crack injections per day, generating $750-$3,000 in daily revenue. The equipment investment is modest — an epoxy injection system runs $500-$2,000. Epoxy injection is appropriate for dormant (non-moving) structural cracks in foundations, slabs, and walls. For cracks with active water leakage, use polyurethane injection instead — epoxy will not bond to wet surfaces.
Routing and Sealing Surface Cracks
Routing and sealing is the standard repair for surface cracks in driveways, patios, and sidewalks. Price: $3-$8 per linear foot. The process: use a crack chaser (diamond blade on an angle grinder) to widen the crack to a uniform 1/4-inch width and 1/2-inch depth. Clean the routed channel with compressed air. Install backer rod (closed-cell foam rope) at 1/2 the channel depth. Apply flexible polyurethane or silicone sealant to fill the channel to surface level. For color-matched repairs, use a polymer-modified cementitious filler tinted to match the surrounding concrete. Material cost per linear foot is $0.50-$1.50 — the expense is labor and equipment. A 60-foot driveway crack routed and sealed at $5 per linear foot generates $300 in revenue for approximately 1.5 hours of work. Routing and sealing prevents water infiltration and freeze-thaw damage while providing a clean, professional appearance. This repair is durable for 5-10 years on horizontal surfaces and should be presented as a maintenance solution, not a permanent fix, to set proper client expectations.
Carbon Fiber Staple and Strip Reinforcement
Carbon fiber reinforcement bridges cracks to prevent further movement and restore structural continuity. Carbon fiber staples (embedded perpendicular to the crack) cost $150-$300 per staple installed. The process: cut slots across the crack with a concrete saw, clean the slots, fill with epoxy, and embed the carbon fiber staple. Space staples at 12-24 inch intervals along the crack. A 6-foot crack with 4 staples runs $600-$1,200 for the staple reinforcement, plus $250-$500 for the crack fill itself, totaling $850-$1,700. Carbon fiber strips (applied along the crack surface) run $300-$600 per strip for foundation wall applications. Material cost per staple is $30-$60; per strip is $50-$100. This specialized repair targets cracks where structural load transfer is critical — foundation walls, load-bearing slabs, and structural beams. The carbon fiber does not add visible bulk to the surface, making it aesthetically superior to steel reinforcement. Marketing carbon fiber crack repair positions you as a structural specialist rather than a cosmetic patcher, justifying premium pricing.
Driveway and Patio Crack Repair Pricing
Driveway and patio crack repair represents the highest-volume residential crack work. Simple crack filling (squeeze-bottle or caulk-applied filler for hairline cracks) runs $2-$5 per linear foot — fast, simple, and appropriate for cosmetic repairs. Professional routing and sealing at $3-$8 per linear foot is the standard-of-care for cracks wider than 1/8 inch. Full-depth structural repair (for cracks that go through the entire slab) requires epoxy injection from below (if accessible) or gravity-feed epoxy from above at $8-$15 per linear foot. Section replacement — saw-cutting out a badly cracked section and pouring new concrete — costs $15-$30 per sq ft of replaced area, including saw-cutting, demolition, forming, reinforcement, concrete, and finishing. Bundle multiple crack repairs into a single project for efficiency and client value. A driveway with 5-8 cracks repaired in a single visit at $200-$400 per crack generates $1,000-$3,200 in 3-5 hours. The recurring nature of crack repair (new cracks develop as concrete ages) builds a loyal client base for annual maintenance visits.
Marketing Concrete Crack Repair Services
Crack repair is one of the most searchable concrete services — homeowners actively Google solutions when they notice cracks. Optimize your online presence for local search terms like "concrete crack repair near me" and "driveway crack repair [city]." Before-and-after photos are your strongest marketing asset — photograph every repair job (with client permission) and post to your website and social media. Offer free or low-cost crack assessments ($0-$150) as a lead generation tool — homeowners who get a professional assessment are 60% more likely to hire you for the repair. Pair crack repair with sealing services — after repairing cracks, recommend a full surface seal at $1.50-$3.00 per sq ft for a comprehensive protection solution that increases your ticket size by 40-60%. Establish minimum service charges ($300-$500 per visit) to ensure profitability on small jobs. Schedule crack repair work to fill gaps between larger flatwork projects — the flexibility of small crack jobs makes them ideal for maintaining crew utilization during schedule gaps or weather delays on bigger projects.
