A blocked sink disrupts your daily routine, whether it happens in the kitchen or bathroom. Kitchen sinks usually block because grease, food bits, and soap build up in the trap and waste pipe. Bathroom sinks are more often affected by hair, soap scum, and toothpaste build-up. Your engineer uses hand rods, high-pressure micro-jetting kit, and powered drain snakes to clear the blockage. This works at any point from the trap under the basin to the underground pipe. They also carry descaling tools for hard water deposits, and grease-cutting attachments for kitchen waste pipes. During the visit, they check the full waste run, not just the visible trap, since a second blockage can bring the problem back. They also check the outside gulley where the waste pipe comes out, as debris often builds up there. Most sink unblocking jobs finish within 30 to 60 minutes, and your engineer checks the flow before leaving.
We check the U-bend or bottle trap under the sink for visible blockages, since that tells us whether the fault sits in the trap or further along the waste pipe.
We remove the blockage using drain rods, a powered drain snake, or targeted micro-jetting, then flush built-up debris from the full length of the waste run.
We check the gulley where the waste pipe leaves the property, since debris there can slow drainage or cause future problems.
We run both taps at full pressure, since that confirms the sink drains freely with no slow drainage or gurgling left.
The cost of unblocking a sink depends on the fixture affected, and whether heavy grease build-up means it needs jetting. Request a fast, fixed-price quote online. We confirm the price before any work starts, and we never charge a call-out fee. If we find a deeper problem, such as a broken pipe, we'll explain your options first.
A kitchen sink that keeps blocking is almost always down to grease and fat building up inside the waste pipe, since even small amounts of cooking oil turn solid as they cool. Using a sink strainer, wiping greasy pans first, and flushing with hot water each week can cut blockages a lot.
Chemical drain cleaners can give short-term relief for small blockages, although they aren't a lasting fix. Since using them a lot can wear down older metal pipes and damage rubber seals, a professional mechanical clear is safer for repeat blockages.
Yes, since a sink's waste pipe often joins the same underground drain as other fixtures. A blockage in that shared section can cause slow drainage or backups in several fixtures, particularly in older terraced homes.
