Cracked sink repair typically costs $150-$500, with an average near $300 for a localized professional repair; replacing the sink can cost $250-$1,200 or more installed. The final price depends on sink material, crack size and location, access to plumbing, and whether the damage can be repaired safely.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Professional crack repair | $100 | $300 | $500 | Small, accessible crack in a repairable surface |
| Sink replacement, installed | $250 | $650 | $1,200+ | Standard sink; premium materials or plumbing changes cost more |
| DIY repair kit | $15 | $40 | $100 | For minor cosmetic damage and compatible materials |
| Plumber labor | $75 | $110 | $175 per hour | May include a minimum service charge |
What a typical cracked sink repair quote includes
Repairing a small chip or hairline crack may cost $100-$250. Larger cracks, color matching, surface preparation, and refinishing can bring a professional repair to $250-$500. These figures generally assume a single sink, normal access, and no cabinet or drain damage.
Repair is not always an option. A crack that leaks, spreads through the basin, or affects a sink’s support may require replacement. A standard drop-in sink replacement often totals $250-$700 installed, while undermount models or higher-end materials can reach $1,200 or more.
Assumptions: Typical U.S. labor rates, standard replacement parts, and no major countertop or plumbing modifications. A small surface defect is much less expensive to address than a structural crack or leaking basin.
How refinishing labor and replacement parts shape the bill
Repair quotes typically combine technician time with repair compounds, color-matching materials, and finishing work. Replacement quotes add the sink itself, removal, installation, and sometimes a new drain or faucet connection. The table shows common components; not every job includes every charge.
| Quote component | Typical price | What it covers |
|---|---|---|
| Repair materials | $15-$100 | Epoxy, filler, primer, and surface coating |
| Repair labor | $100-$350 | Preparation, filling, sanding, and refinishing |
| Replacement sink | $50-$500 | Basic stainless or porcelain through premium models |
| Removal and installation labor | $150-$450 | Disconnecting, setting, sealing, and reconnecting |
| Drain parts or disposal | $20-$150 | New drain components and old-sink haul-away |
Labor pricing varies by trade and market. A repair technician may bill for a minimum visit even when the hands-on work takes less than an hour; a replacement commonly requires two to four hours. Ask whether the estimate includes the service minimum, removal, and cleanup before comparing totals.
Does crack length, sink material, or location change the price?
Yes. A hairline crack under 2 inches that does not leak is usually simpler than a crack longer than 6 inches or one reaching the drain opening. A technician may decline repair when the basin flexes, the crack passes through the sink, or water is escaping into the cabinet.
Porcelain and cultured marble can sometimes be filled and refinished, but an exact color match may add $50-$150. Fiberglass and acrylic repairs depend on the damage and finish. Stainless-steel cracks or splits often call for replacement rather than a cosmetic patch. Undermount sinks can add $100-$300 in labor compared with an accessible drop-in sink because removal and support take longer.
Material and crack location matter as much as the visible length. A crack near a faucet hole, drain, or mounting point can compromise the structure even if it looks small.
Lower the cracked sink bill by choosing repair carefully
Before approving work, ask the contractor whether the repair will be waterproof, how long the finish needs to cure, and whether the repair carries a workmanship warranty. If the sink is old, leaking, or visibly unstable, compare a replacement quote rather than paying for a temporary patch.
For replacement, keeping the same sink type and dimensions can avoid countertop cutting and cabinet changes. A basic, in-stock model may cost $50-$200, while specialty finishes, unusual sizes, and premium fireclay or stone can raise the purchase price. Keeping the existing opening and plumbing layout is often the most controllable way to limit replacement labor.
Repair versus replacement for porcelain, steel, and composite sinks
Professional refinishing is most useful when a porcelain or composite sink has a small, stable surface crack and the rest of the basin is sound. A $200-$450 repair may preserve the existing fixture, but it may remain visible and can fail if the crack moves. DIY kits cost roughly $15-$100, though they may not match the original glaze or provide a durable finish.
Replacement is often the better long-term choice for a leaking basin, multiple cracks, rust-through, or a damaged mounting edge. Basic drop-in sinks are generally less expensive to install than undermount or integrated models. Replacing an integrated countertop-and-sink unit can cost $700-$2,000 or more because the work may involve the counter as well as plumbing.
Compare the repair warranty and expected durability with the full installed replacement quote. A low initial repair price may not be economical if the basin is structurally compromised.
Three cracked sink quotes with different damage and scope
| Example | Work and assumptions | Estimated total |
|---|---|---|
| Small porcelain chip | One technician, 2 hours at $100 per hour; filler and touch-up | $250-$350 |
| Long cultured-marble crack | 3-4 hours of prep and refinishing; color-matched materials | $350-$600 |
| Leaking drop-in sink | $150-$300 sink, 2-3 labor hours, drain parts and disposal | $450-$850 |
These examples exclude extensive cabinet repairs and unusual countertop work. A quote for a crack that leaks should specify how the installer will protect the cabinet and confirm the new sink fits the existing opening.
Why urban and rural sink repair quotes differ
Labor and trip charges can put urban or high-cost coastal quotes about 10%-25% above a typical national estimate. Rural customers may face a similar premium when a specialist must travel a long distance, although local labor rates can be lower. Emergency scheduling or a same-day appointment may add $50-$150.
Ask for an itemized estimate that separates diagnosis, repair or installation labor, materials, disposal, and any plumbing changes. Two written quotes based on the same sink material and job scope make regional price differences easier to judge.
