Plumber sink repair cost is one of the first things homeowners want to know before booking a service call. Plumber sink repair cost changes widely based on the type of sink, the type of damage, and how quickly a repair is needed.
Kitchen sinks and bathroom sinks fail for different reasons, and each repair comes with its own pricing structure. Homeowners who understand basic pricing patterns can make smarter decisions about repairs, maintenance, and when to replace parts instead of fixing them.
These ranges reflect typical plumbing labor rates, the cost of materials, and time spent on the job. Any repair connected to garbage disposals, dishwasher drains, or cast-iron piping increases sink repair costs significantly.
Factors That Influence Plumber Sink Repair Cost
Most sink issues fall into a few predictable categories, and each one affects plumber sink repair cost differently. Common factors include:- Severity of the leak or clog
- Location of the damage
- Accessibility under the sink
- Replacement parts
- Emergency or after-hours scheduling
- Experience level of the plumber
Common Issues That Affect Pricing
Kitchen sink leaks usually happen at the drain basket, P-trap, or supply lines. Bathroom sinks often develop clogs deep in the pop-up assembly or corrosion around the tailpiece. Sink leaks that remain visible often cost less to fix because the plumber spends less time identifying the source. Hidden leaks behind cabinets require more labor time, which raises the plumber sink repair cost.Typical Repair Costs for U.S. Homeowners
Most U.S. homeowners encounter four main repair categories. Below is a simple breakdown to help compare expected pricing.| Repair Type | Average Cost Range |
| Minor leak at the P-trap or gasket | $75–$150 |
| Clogged kitchen or bathroom sink drain | $100–$250 |
| Replacing under-sink pipes | $150–$450 |
| Full kitchen sink drain assembly repair | $180–$500 |
Kitchen Sink Repair Pricing
Kitchen sinks often cost more to fix than bathroom sinks because they handle grease, food debris, and higher water volume. The cost of repairs for a kitchen sink depends on whether the plumber needs to snake the drain, replace a corroded tailpiece, or rebuild the entire drain assembly. Repairs involving disposal units or dishwasher drain lines add time, which increases plumber sink repair cost.

Bathroom sinks usually fail due to clogs in the pop-up mechanism, loose slip nuts, or old metal drain parts. These repairs cost less than kitchen sink issues because fewer components are involved. Carbon buildup and toothpaste clogs are easy fixes, but cracked drain pipes or rusted flanges increase the final plumber sink repair cost.When DIY Helps and When to Call a Pro
DIY sink repairs can save money, but only when the problem is simple and tools are available. Homeowners can safely handle:- Tightening loose slip nuts
- Replacing a P-trap
- Cleaning a pop-up drain
- Clearing minor clogs with a hand auger
Labor Costs and What Homeowners Should Expect
Plumbing professionals typically charge by the hour for diagnostic work and complex repairs. Typical plumber hourly rate in most U.S. regions: $75–$150 per hour. Licensed experts with advanced leak-detection tools may charge higher, but accurate diagnostics often reduce the total number of service hours. This is why homeowners see wide variations in the final plumber sink repair cost.Preventing Future Sink Repairs
Homeowners who stay on top of home plumbing maintenance avoid the most expensive sink repairs. Simple habits keep drains healthy:- Scrape plates before using the disposal
- Avoid pouring grease down the drain
- Check under-sink pipes monthly
