What the signs are telling you?
A blocked sink rarely stays a blocked sink for long. What starts as slow drainage can turn into smells, gurgling, overflow or water backing up into nearby fixtures.
We handle sink, basin, shower, bath and floor waste blockages, along with the internal drain lines connected to them. If the issue turns out to be wider than one fixture, our blocked drains service covers broader drainage problems too.
Signs you need a plumber
Slow drainage, bad smells, bubbling sounds, water sitting in the bowl or basin, and waste water appearing in another nearby drain are all warning signs. If the same drain keeps blocking, there is usually an underlying cause that needs to be found and fixed.
What usually causes it
In bathrooms, the usual culprits are hair, soap scum and residue building up over time. In kitchens, it is more often grease, food waste and sludge inside the pipework. Some blocked sink Gold Coast callouts also trace back to a deeper drain issue, not the sink itself. If your toilet is also struggling, our blocked toilet service may be relevant as well.
What to do right now
If the sink is not draining, stop using it until the water level drops. Avoid repeatedly pouring supermarket drain chemicals down the waste, especially if the blockage keeps coming back. They can be harsh, messy and often do not solve the actual cause. For simple pre-visit steps, see what to do before the plumber shows up.
When to treat it as urgent
If multiple fixtures are backing up, wastewater is rising into showers or floor wastes, or the smell is getting worse, do not leave it. That usually points to a deeper blockage in the line. For urgent help, our emergency blocked drains service is available when the problem cannot wait.
How we clear it properly
The key is working out whether the blockage is local to the fixture or further down the line. That is why we do not rely on guesswork.
We check what is affected, assess how the drain is behaving, then use the right equipment to clear the blockage and reduce the chance of it coming straight back.
How we find the cause
If one sink is slow, the issue may be close to the trap or waste line. If nearby fixtures are involved too, the blockage is often further along the drainage system. Where needed, we use a CCTV drain camera inspection to look inside the pipe and confirm whether the problem is grease, debris, roots, a broken section, or something else.
How we fix blocked sinks and drains
Some blockages can be cleared locally. Others need professional drain clearing equipment, such as high-pressure jetting, to break through heavy build-up and restore flow properly. If the issue sits outside the internal waste line, such as surface drainage after rain, our blocked stormwater drain service may be the better fit.
How to help stop it happening again
Keep grease, oil, coffee grounds and food scraps out of kitchen drains, and use strainers where practical in bathroom basins and showers to catch hair and debris. If a drain is already slowing down or smelling off, act early. Our guide on how to unblock a sink covers a few simple ideas, but recurring issues usually need a proper inspection.
What to expect on the day
First, we inspect the affected fixtures and work out where the blockage is likely sitting. Next, we explain what we have found and give you an upfront price before starting. Then we clear the drain, test the flow, and let you know if there is anything else worth fixing while we are there.

Blocked Sinks & Drains FAQs
The most common signs are slow drainage, bad smells, gurgling noises, water backing up into nearby fixtures, and repeat blockages. If more than one fixture is affected, the blockage may be deeper in the line.
Bathroom sinks and showers usually block because of hair and soap build-up. Kitchen sinks are more commonly affected by grease, oil and food waste. In some cases, the real problem is deeper in the drainage system.
If other fixtures are draining slowly, making noises, or backing up when you use the sink, the blockage is often beyond the fixture itself. CCTV inspection can help confirm exactly what is going on inside the pipe.
The cost depends on what is causing the blockage, where it is located, how easy it is to access, and what equipment is needed to clear it. We assess the issue first and give you an upfront price before starting the work.
Simple local blockages can often be cleared quickly. More involved jobs take longer if the blockage is deeper in the line or if camera inspection is needed to confirm the cause.
Stop using the sink if the water is backing up, avoid repeated chemical treatments, and arrange a plumber if it is not clearing easily or keeps happening. The sooner the cause is checked, the less chance there is of a bigger drainage problem developing.
