Sink Plumbing in Dedham, MA
Repair of kitchen and bathroom sink drains, traps, supply lines, and the leaks and odors that come from beneath the sink.
Most sink problems live in a small space: the trap, the drain assembly, and the supply connections under the basin. That concentration is good news — it means most sink visits are contained, diagnosable, and quick to resolve once the right spot is found.
Kitchen and bathroom sinks diverge in what goes wrong. Kitchens deal with grease, food waste, and disposal connections; bathrooms deal with hair, soap, and pop-up assemblies. The shared thread is that a slow or smelly sink is usually telling you about its trap or its drain, not about the whole house.
Common Symptoms
- Water draining slowly from a sink
- A smell coming from a sink drain
- Dampness or drips in the cabinet beneath a sink
- A gurgling sink when other fixtures run
- A pop-up stopper that sticks or will not seal
- Staining or swelling in the cabinet floor
What Could Be Causing It
- A trap partially blocked by grease, hair, or soap buildup
- A failed or dry trap letting sewer gas through
- Loose or worn drain and supply connections
- A pop-up assembly that no longer seals or moves freely
- A disposal or dishwasher connection leaking into the cabinet
How the Problem Is Assessed
Assessment opens the cabinet: the trap's condition, the drain and supply connections, the stopper assembly, and any sign of past leaks in the cabinet floor. The pattern — one sink or several — decides whether the problem stays under the sink or goes further down the line.
What to Expect During Service
The trap or connection is repaired or replaced, the drain is tested, and the cabinet is left dry. If the problem is further down the line, that is explained rather than treated as a sink problem, so the fix matches the cause.
Safe Checks You Can Do First
- Look inside the cabinet for active drips and note where they start
- Run the tap and watch the trap and connections, not just the basin
- Check whether the smell appears only after the sink has sat unused — a dry trap is a common cause
- Avoid chemical drain cleaners in a slow sink
- Keep the cabinet clear so a future leak is spotted early, not after it swells the floor
Repair or Replace?
Traps, stoppers, and connections are repairs. Replacement of a sink itself is a separate decision — usually driven by the basin's condition or a renovation, not by a drain problem, which lives below the sink.
What Affects the Cost
Every job differs, so fixed prices are not quoted on this site. The factors that shape the cost of sink plumbing include:
- Which component has failed — trap, stopper, connection, or supply line
- Whether the problem is local to the sink or further down the drain
- Accessibility of the cabinet and connections
- Whether a disposal or dishwasher connection is involved
- Any cabinet or floor damage found during the visit
Frequently Asked Questions
Why does my sink smell even when it drains fine?
Often a dry or faulty trap: the water seal that blocks sewer gas has evaporated or failed. Running the tap restores a dry trap's seal; a damaged trap needs replacing.
Is a slow bathroom sink the same problem as a slow kitchen sink?
Usually not. Bathroom sinks slow from hair and soap in the trap and pop-up; kitchen sinks slow from grease and food. The clearing approach differs, which is why the location matters.
Should I replace the whole trap or just clean it?
Cleaning solves a simple blockage. Replacement fits when the trap is corroded, cracked, or repeatedly blocking — a new trap is inexpensive and removes the recurring cause.
What is that damp patch in my sink cabinet?
Most often a slow drip from a drain or supply connection. Finding which connection, and whether it drips only when the tap runs, points to the repair.
