Toilets and sinks
Internal blockages cleared without lifting floors or removing the pan wherever possible.
Drain Unblocking in Hertfordshire
Fast, fixed-price drain unblocking, day or night
We clear blocked toilets, sinks, manholes and drains quickly and professionally — with no call-out fee. Drain 247 is a family-run drainage team based in Watford, covering Hertfordshire and north west London 24 hours a day.
A real person answers the phone, we agree a fixed price before any work starts, and we bring the right plant for the job rather than a set of rods and a hope. In the vast majority of call-outs the blockage is cleared on the first visit. If the pipe itself is cracked or collapsed we will show you the camera footage and quote the repair separately, rather than charging you to clear a drain that will only block again.
Why choose Drain 247
Local engineers
Based across Hertfordshire, so we are not travelling in from another county.
24/7 emergency response
A real person answers the phone at three in the morning, not an answerphone.
No call-out fees
Fixed, transparent pricing agreed with you before any work starts.
Over 150 five-star reviews
Most of our work comes from recommendations and repeat customers.
Older drainage systems
Specialists in the pitch fibre and clay runs common in Hertfordshire properties.
Survey and repair together
CCTV surveys and no-dig repairs available on the same visit.
Signs you have a blocked drain
Catching these early is usually the difference between an hour with the rods and an excavation.
Gurgling sounds
Toilets or sinks gurgle as air is forced back up past a partial blockage.
Slow draining water
Basins, baths and showers take noticeably longer to empty than they used to.
Bad smells from plugholes
Trapped waste sitting in the pipe starts to give off a persistent drain odour.
Rising water in manholes
Lift the cover: if the chamber is full, the blockage is downstream of it.
Flooding around drains
Water pooling at a gully or drain cover after rain means the run cannot clear.
Same-day diagnosis
In Watford, Bushey, Rickmansworth, St Albans or Hemel Hempstead we can normally diagnose and clear it the same day.
What we unblock
Every type of blockage, inside the property and out.
Baths and showers
Hair, soap and scale build-up removed from waste pipes and traps.
Urinals and bidets
Descaling and clearing for commercial washrooms, including planned maintenance.
Gullies and gutters
Leaf litter, silt and debris cleared so surface water drains away properly.
Manholes and drains
Main runs jetted clear, with a camera check afterwards if the cause is not obvious.
ACO and channel drains
Driveway and patio channel drains lifted, cleaned and reseated.
How we unblock drains
Most plumbers only carry rods. We bring proper drainage equipment, so the blockage is removed rather than pushed further down the pipe.
-
Manual rodding and plunging
Perfect for internal blockages, toilets, sinks and soft debris. Often all that is needed, and always the first thing we try.
-
High-pressure water jetting
Ideal for external drains, fatbergs, grease, silt and scale. Our jetting units run at over 3,000 PSI, which scours the pipe wall clean rather than just punching a hole through the blockage.
-
Electro-mechanical cutting
Used for tree roots, concrete, hard scale and stubborn obstructions that jetting alone will not shift.

Domestic and commercial drain unblocking
We work with homeowners, landlords, restaurants, offices and property managers right across Hertfordshire.
Commercial work includes pre-planned maintenance, grease trap cleaning, urinal descaling, CCTV drain surveys and no-dig patch repairs — and we can carry out a survey and a repair on the same visit rather than booking you in twice.
If the drain is still backing up
You do not need to decide between rods, jetting or a camera first. Describe the symptom and we will tell you the likely cause, when we can be there, and what it will cost.
What our customers say
Brilliant service, they helped unblock my drain really quickly. Would definitely recommend!
An absolute pleasure to deal with. George arrived at my house quickly to take care of a blockage in my drain. He cleared it in less than an hour and was very knowledgeable. Brilliant service.
I really needed someone to come and unblock my outside drain as it was causing flooding issues. I found these guys online and they came the same day. Very impressed and will recommend to others.

Common questions about blocked drains
How quickly can you get to me?
For an emergency in Watford or the surrounding towns we are usually with you within a couple of hours, and often sooner. We will give you a realistic arrival window on the phone rather than an optimistic one.
Will you charge me if you cannot clear the drain?
No. There is no call-out fee, and if we cannot clear the blockage there is nothing to pay. If the drain needs a repair rather than a clearance we will show you the camera footage and quote separately for that work.
Who is responsible for the blocked drain, me or the water company?
As a rule, pipework inside your property boundary is yours, and the shared sewer beyond it belongs to Thames Water. A camera survey settles the question quickly, and we will tell you honestly if the blockage is one you should not be paying for.
Is jetting safe for older pipes?
Yes, when the pressure is matched to the pipe. Many Hertfordshire properties still have pitch fibre or clay runs, and we survey first and reduce the pressure accordingly rather than putting a standard jetting head down an old drain.
Do you work at weekends and overnight?
We do. The phone is answered 24 hours a day, 365 days a year, and our out-of-hours rate is the same as our daytime rate.
