Do You Have a Blocked Drain, Toilet or Sink?
Blocked drains and fixtures can quickly disrupt daily life. A slow-draining sink may seem minor at first, but repeated blockages, bad smells, water backing up or an unusable toilet can point to a problem that needs attention.
You may need unblocking help if you notice:
- A toilet that will not flush properly
- Water rising when you flush
- A sink that drains slowly
- Water backing up into a bath, shower or sink
- Bad smells from drains
- Gurgling sounds from pipework
- Repeated blockages in the same fixture
- Standing water in a shower or bath
- Wastewater backing up
- More than one fixture draining slowly
Common Blockages We Help With
Fix Your House helps with common household blockages across North West London. We assess the affected fixture, check the likely cause and clear the blockage where possible.
Blocked Toilets
A blocked toilet can become urgent, especially if it is the only toilet in the property, if water is rising or if wastewater is backing up. Avoid repeated flushing if the water level is high.
Blocked Sinks
Kitchen and bathroom basins can become blocked by grease, soap residue, hair, food waste, scale, small objects or build-up in the waste pipe.
Blocked Baths and Showers
Baths and showers often drain slowly because of hair, soap, product residue or waste pipe build-up. Standing water can make the bathroom difficult to use.
Slow-Draining Fixtures
Slow drainage can be an early sign of a developing blockage. If more than one fixture is slow, the issue may be further along the drainage line.
Bad Smells from Drains
Bad smells can be linked to trapped waste, poor drainage, dried traps, blocked waste pipes or recurring build-up.
Recurring Blockages
If the same toilet, sink, bath or shower keeps blocking, the issue may not be fully cleared or there may be an underlying problem that needs further investigation.
Why It Is Better Not to Ignore a Blockage
Not every blockage is an emergency, but leaving it unresolved can make the problem more disruptive. Water backing up, bad smells and repeated blockages can affect normal use of your bathroom or kitchen and may increase the risk of leaks or damage around fixtures.
Possible risks include:
- Toilets becoming unusable
- Wastewater backing up
- Water overflowing from fixtures
- Bad smells spreading through the property
- Damage around floors, cabinets or bathroom fittings
- Repeated blockages becoming more frequent
- Hidden leaks from waste pipe connections
- More disruptive repair work later
What to Do Before We Arrive
If you have a blocked toilet, sink, bath, shower or drain, a few simple steps can help reduce the chance of overflow or further disruption.
If it is safe, you can:
- Stop using the affected fixture
- Avoid repeated flushing if the toilet water is rising
- Avoid pouring more water into a blocked sink, bath or shower
- Move items away from the affected area
- Place towels around minor overflow areas
- Keep children and pets away from wastewater
- Avoid using harsh chemicals if the blockage is severe
- Take photos or a short video if water is backing up
- Tell us whether more than one fixture is affected
Do not attempt to dismantle pipework if you are unsure what is causing the blockage or if wastewater is present.

Toilet, Sink, Bath or Shower Blockage?
Different fixtures can block for different reasons. Understanding where the issue appears helps decide the most practical next step.
- Toilet Blockages: May be caused by excess paper, wipes, sanitary products, small objects, scale, poor flushing or a problem further along the waste pipe.
- Kitchen Sink Blockages: Often caused by grease, food waste, soap residue or build-up in the waste pipe. Repeated kitchen sink blockages may need closer inspection.
- Basin Blockages: Can become blocked by hair, soap, toothpaste, product residue or small items trapped around the waste.
- Bath and Shower Blockages: Commonly caused by hair, soap residue, product build-up or waste pipe restrictions. Slow drainage is often an early warning sign.
- Multiple Fixtures Affected: If several fixtures are draining slowly or backing up at the same time, the issue may be deeper in the drainage system and may need further investigation.
When a Blockage May Be Urgent
Some blockages need faster attention, especially if wastewater is backing up or the fixture cannot be used.
A blockage may be urgent if:
- The only toilet in the property is blocked
- Water is rising when you flush
- Wastewater is backing up
- More than one fixture is affected
- Water is overflowing onto the floor
- The blockage is causing bad smells throughout the property
- A bath, shower or sink cannot drain at all
- The blockage keeps returning quickly after clearing

Blocked Drains FAQs
What should I do if my toilet is overflowing?
Stop flushing, avoid using the toilet and move items away from the area. If wastewater is present, keep children and pets away and call for help.
