Steven Jennings, drainage specialist
Blocked Up Drainage is Steven's business and Steven's van. He is here to take the stress away when nothing is draining: the washing up, the toilet, the bath or the shower. Fifteen years of blockages, inside and outside the property, and nothing he has not come across.

Fifteen years, one man, one standard
Steven Jennings started clearing drains fifteen years ago and has run Blocked Up Drainage as his own business ever since. There is no call centre and no subcontractor: when you ring 0800 193 1471 you speak to Steven, and when the van pulls up it is Steven who gets out of it.
Fifteen years of blocked toilets, slow sinks, flooded gullies and collapsed drains means he has usually seen your problem before and knows what it will take to clear it. High-pressure jetting, drain rods and a CCTV camera travel on the van, so most jobs are finished on the first visit, with no call-out fee and an hourly rate agreed before he starts.
He covers the whole of Hertfordshire and everywhere inside the M25, and he is polite, punctual and straight with you. If something needs a proper repair rather than another clearance, he will show you why and give you the options. If it does not, he will say that too.
- Steven answers the phone himself, day or night.
- He turns up when he says he will.
- He explains what he finds in plain English.
- He clears the blockage and tells you how to stop it coming back.
- No call-out fee, and your home is left as he found it.
