What our customers say
Drain 247’s mapping saved our project from delays. Clear plans, fast service.
Great service and a great team of engineers. Wouldn’t hesitate to recommend to anyone. Work carried out to a high standard and the call-out was within the required time. Five stars from start to finish.
Turned up when they said they would, told me the price up front, and cleared a blockage two other firms had failed on.
Specialist capability
Beyond emergency unblocking
Our high-capacity vacuum tankers handle liquid waste disposal and rapid water extraction during basement floods. For properties with large surface water demands, we deliver planned maintenance rather than repeat emergency visits.
We also tackle biological issues with robotic root cutting and high-pressure descaling, which removes years of mineral build-up in older pipework. Whether you manage a single home or an industrial estate, your drainage assets are maintained to the highest NADC standards.

Common questions
How quickly can you get to me?
We reach most call-outs across Watford, St Albans, Hemel Hempstead and Borehamwood within 60 to 90 minutes. If you are further out we will tell you honestly how long it will take when you call, rather than quoting a time we cannot meet.
Do you charge a call-out fee?
No. We agree a fixed price for the work before an engineer sets off, and that is the figure you pay. There are no hourly surprises and no out-of-hours surcharges.
Who is responsible for the blocked drain — me or the water company?
As a general rule, pipework inside your property boundary is your responsibility, and shared or public sewers beyond it belong to the water company. It is not always obvious where that line falls, so we identify it as part of the survey and tell you if the cost should sit with Thames Water rather than you.
Will you need to dig up my garden or driveway?
Usually not. Cured-in-place pipe lining lets us repair cracked or collapsed pipes from the inside, with no excavation. We only recommend digging when the damage genuinely cannot be repaired any other way, and we will show you the CCTV footage that explains why.
Do you work on weekends and bank holidays?
Yes. We are a genuine 24/7 service, every day of the year, and the price does not change because it is a Sunday or Christmas Day.
What does a CCTV drain survey involve?
We feed a high-resolution camera through the drainage run and record the whole system. You get footage, still images and a written report identifying any defects, their location and their severity — which is what mortgage lenders, insurers and building control usually ask for.
