Blocked Drains, Toilets & Sinks
A blockage affecting one sink, bath or toilet may be in its trap or waste pipe. If several fittings back up at once, the fault may be further along a shared soil stack or outside drain. We identify the affected run and use rodding or mechanical clearance where suitable; specialist jetting is not part of our current offer.
One slow sink is a local problem. A slow sink, a gurgling shower and a rising toilet at the same time is a drainage problem, and the difference decides whether the fix takes twenty minutes or needs the manhole lifted.
We clear the blockage, then look for why it happened — because a drain that blocks twice in a year is usually telling you about a fallen joint, root ingress or a badly laid waste run.

- Clearing blocked toilets, basins, sinks, baths and showers

What we get called out to most

- Bad smell from an outside gully
- Waste water surfacing at a manhole cover
How the job runs
- 1
Identify
Establish whether the blockage is local to one fitting or in the shared run.
- 2
Access
Use the nearest sensible access point — trap, rodding eye or chamber.
- 3
Clear
Plunge, rod or use mechanical clearance according to the blockage and access. If specialist jetting is needed, we explain that limitation before starting.
- 4
Flush
Run the fittings through to confirm free flow.
- 5
Advise
Tell you honestly if the drain needs further investigation.
What it costs
Simple internal blockages are charged as a call-out that includes the first hour on site — £99 standard hours (8am–6pm), £129 evenings (6pm–10pm) and Saturdays, £169 nights (10pm–8am), £149 Sundays and £199 bank holidays — with any further time at £95 per hour. External drain clearance depends on access and equipment — we confirm the cost before starting.
