A blocked sink stops your kitchen or bathroom working properly. Kitchen sinks often block from grease and food waste, while bathroom sinks clog with hair and soap scum. Our engineers clear the trap and waste pipe with rods, a drain snake, or high-pressure jetting, and they check the outside gulley too. We test the flow before we leave, so you know the blockage is gone for good.
Before you send a request, our guide 7 Warning Signs You Have a Blocked Drain explains what to look for and what your options are. It also covers the questions we usually ask when you get in touch.
We check the U-bend or bottle trap under the sink for visible blockages. Since this tells us whether the blockage sits in the trap or further along the waste pipe, it shapes how we clear it.
We use drain rods, a powered drain snake, or targeted micro-jetting to clear the blockage. We then flush out any built-up debris along the full waste run.
We check the gulley or hopper where the waste pipe leaves the property. We clear any debris there that could slow drainage or cause future problems.
We run both taps at full pressure to check the sink drains freely. This confirms there is no slow drainage or gurgling left, and the blockage is fully gone.
Sink unblocking costs depend on how much grease has built up, and whether it needs jetting, since kitchen sinks usually need more work than bathroom basins. We confirm the price before any work begins. If we find a deeper problem, such as a broken pipe, we explain your options first. Request a quote online.
Grease and fat build-up inside the waste pipe causes most repeat kitchen sink blockages. Even small amounts of cooking oil turn solid as they cool, and this slowly narrows the pipe. A sink strainer, wiping greasy pans before washing, and a weekly hot water flush can cut how often it blocks.
Chemical drain cleaners can ease a minor blockage for a while, but they are not a lasting fix. Repeated use can wear down older metal pipes and damage rubber seals. For a full or stubborn blockage, mechanical clearing works better and is safer for your pipes.
Yes. If a sink waste pipe shares an underground drain with other fixtures, a blockage in that shared section can slow or back up several appliances at once. This is common in older terraced homes, where the kitchen and bathroom often share one pipe run.
