A blocked sink disrupts your daily routine, whether it's in the kitchen or the bathroom. Kitchen sinks usually block from grease, food scraps, and soap building up in the trap. Bathroom sinks, however, tend to clog from hair, soap scum, and toothpaste.
We use manual rodding, micro-jetting, and drain snakes to clear the blockage. Since the visible trap isn't always the whole story, we check the full waste run for anything further along. The outside gulley often collects debris too, so we check that as well.
Most sink jobs finish within 30 to 60 minutes, although a heavier grease blockage can take longer. Ask the engineer to run the taps and check the flow before they leave.
We check the U-bend or bottle trap beneath the sink for visible obstructions. This tells us whether the blockage sits in the trap or further along the waste pipe.
We use drain rods, a powered snake, or targeted micro-jetting to remove the blockage. While we're there, we flush out any debris along the full waste run.
We inspect the gulley where the waste pipe leaves your property. Clearing debris here helps prevent the same problem coming back.
We run both taps at full pressure and check the sink drains freely. This confirms the blockage has gone for good, with no gurgling or slow flow left behind.
The cost of unblocking a sink depends on the blockage type, since heavy grease sometimes needs jetting to clear it fully.

If we find a deeper problem such as a broken pipe, we explain your options before starting.
Recurring kitchen sink blockages are almost always caused by grease and fat accumulation inside the waste pipe. Even small amounts of cooking oil solidify as they cool, gradually narrowing the pipe. Using a sink strainer, wiping greasy pans with kitchen roll before washing, and flushing the drain with hot water weekly can significantly reduce blockage frequency.
Chemical drain cleaners can provide temporary relief for minor blockages but are not a long-term solution. Repeated use can corrode older metal pipes and damage rubber seals. For persistent or complete blockages, professional mechanical clearance is more effective and safer for your pipework.
Yes. If a sink waste pipe connects to the same underground drain as other fixtures, a blockage in the shared section can cause slow drainage or backups in multiple appliances. This is particularly common in older terraced properties where kitchen and bathroom waste share a single pipe run.
