You hear a knock at the door. “It’s the plumber—I’ve come to fix the sink!” Relief washes over you—your clogged or leaking sink is finally getting professional attention. But what should you expect during the visit? How can you make the most of their time (and your money)? Whether it’s a minor drip or a full-blown kitchen disaster, understanding the process helps you stay in control and avoid unnecessary costs. In this guide, we’ll walk you through everything you need to know when “It’s the plumber—I’ve come to fix the sink!” becomes your reality.
What Does a Plumber Actually Do When Fixing a Sink?
When a plumber arrives to fix your sink, they don’t just tighten a few bolts and leave. A professional follows a systematic approach to diagnose, repair, and prevent future issues.
Step-by-Step: A Plumber’s Sink Repair Process
Initial Assessment (5–10 minutes) The plumber will ask about symptoms: Is it leaking? Slow-draining? Making gurgling sounds? They’ll inspect visible pipes, faucets, and the P-trap under the sink.
Diagnostic Testing
For clogs: They may use a drain auger or camera inspection.
For leaks: They check connections, seals, and water pressure. According to the National Association of Home Builders, 68% of plumbing service calls involve kitchen or bathroom sink issues—most stemming from improper disposal use or worn-out seals.
Repair or Replacement
Minor leaks: Replacing washers or O-rings (cost: $50–$150).
Clogs: Snaking the drain or hydro-jetting ($100–$250).
Full faucet replacement: $150–$400, including labor.
Cleanup & Testing After the fix, they’ll run water to test functionality and ensure no new leaks appear.
💡 Pro Tip: Clear the area under your sink before the plumber arrives. Remove cleaning supplies, trash, or stored items—this saves time and shows you’re prepared.
DIY vs. Calling a Pro: When Should You Wait for “It’s the Plumber”?
Many homeowners attempt DIY fixes, but not all sink issues are safe or cost-effective to handle alone.
DIY Sink Fixes: What’s Safe?
✅ Safe for DIY:
Using a plunger on a slow drain
Tightening loose faucet handles
Replacing a worn aerator (costs under $5)
❌ Call a Pro Immediately If:
Water is pooling under the cabinet
You smell sewage gas (could indicate a broken P-trap seal)
The faucet drips even after replacing cartridges
You’ve already tried chemical drain cleaners (they can damage pipes)
According to a 2023 study by HomeAdvisor, 42% of DIY plumbing attempts lead to more expensive repairs within 6 months—often due to misdiagnosis or improper tool use.
📌 Remember: Plumbers are trained in local building codes. A botched DIY job could violate regulations and void your home insurance during inspections.
How to Prepare for Your Plumber’s Visit
Maximize efficiency (and minimize costs) by preparing ahead of time.
Checklist Before the Plumber Arrives:
✅ Document the issue: Take a short video of the leak or clog.
✅ Clear access: Empty the cabinet under the sink.
✅ Note water behavior: Does it only leak when the dishwasher runs? Does hot water drain slower?
✅ Have your home’s age ready: Older homes may have galvanized steel pipes (prone to corrosion)—this affects repair strategy.
Musty odor under the sink → Hidden mold from chronic leaks
A licensed plumber can perform a video pipe inspection (cost: ~$200–$350) to view hidden damage inside walls or under slabs—saving you from future structural repairs.
