Kitchen and Bathroom Sink Repair
Home › Plumbing Services › Kitchen and Bathroom Sink Repair

Sinks are used more than almost any other fixture, so small problems show up fast. Plumber On Demand repairs leaking traps, clears slow drains and replaces kitchen and bathroom sinks cleanly, without leaving a mess in your cabinet or countertop.
Sink problems we fix
- Leaking P-traps and drain connections that drip into the cabinet below
- Slow or clogged sink drains from grease, food, soap and hair
- Leaking supply lines and shutoffs under kitchen and bathroom sinks
- Garbage disposal connections and dishwasher drain hook-ups
- Loose or cracked sinks and failed sealant around the basin
- Bad smells from the drain often caused by a dry trap or venting problem
Clearing slow sink drains
Kitchen sinks usually clog from grease and food waste, while bathroom sinks clog from hair and soap. We clear the trap and the line behind it so water drains freely, and let you know if the clog is further down the pipe. For drains that keep coming back, see our drain services.
Sink replacement and installation
Replacing a sink is a good time to update the trap, shutoffs and supply lines too. We disconnect and remove the old sink, install the new one with the right fittings, reconnect faucets, disposals and dishwashers, and test everything for leaks. Undermount, drop-in, vanity and utility sinks are all part of the job.
Do not ignore a slow drip
A small leak under a sink can quietly rot cabinet bases and cause mould. If you see water stains, swelling wood or a musty smell under the sink, call us before it becomes a larger repair.
Kitchen and Bathroom Sink Repair FAQs
Why does my sink cabinet keep getting wet?
The most common causes are a loose trap connection, a worn supply line or a leaking faucet base. We can find and fix the exact source.
Can you install a sink I already bought?
Yes. We install sinks you have purchased and let you know if extra parts are needed for the connection.
Why does my bathroom sink smell?
A sewer smell usually means the trap is dry, the drain is dirty, or there is a venting problem. Cleaning the drain often helps, and we can check the trap and venting if it does not.
