Expert Drainage Engineers
From a slow-draining sink to a fully blocked main drain, our drainage engineers clear, diagnose and repair domestic and commercial drainage across London and Surrey. We carry high-pressure jetting and CCTV survey equipment to fix the cause, not just the symptom, in a single visit wherever possible.
Every job is charged at a clear hourly rate with no hidden call-out fees, and we take card payment securely on completion. You always know where you stand before we start.
What Our Drainage Engineers Do
The full breadth of drainage work we carry out across London and Surrey — in detail.
Emergency Drain Unblocking
Overflowing drains and sewage backing up indoors can't wait, and we treat them that way. We clear blocked sinks, toilets, stacks and main runs fast — then tell you honestly whether it was a one-off or a symptom of something that needs a proper look.
High-Pressure Water Jetting
Rods push blockages further down the line; jetting removes them. Our high-pressure jetting cuts through grease, scale and compacted waste and scours the pipe walls clean, restoring full flow rather than just poking a hole through the problem.
CCTV Drain Surveys & Reports
When a drain keeps misbehaving, we put a camera down it and show you exactly what's going on — cracks, root ingress, scale, displaced joints or bad falls. You get a clear recorded survey and a plain-English report, ideal for recurring problems and pre-purchase checks.
Drain Repairs & No-Dig Relining
Cracked and root-damaged drains can often be relined from inside the pipe — a structural repair without excavating the garden or driveway. Where digging is genuinely the right answer, we excavate cleanly, repair properly and reinstate the surface.
Recurring Blockage Diagnosis
A drain that blocks every few months is telling you something. We find the underlying cause — roots, scale build-up, a belly in the run or a collapsed section — and fix that, ending the cycle of paying to clear the same blockage again and again.
Gullies, Soakaways & Outside Drainage
Flooded patios and overflowing gullies usually trace back to silted gullies, blocked downpipe connections or tired soakaways. We clear, repair and rebuild outside drainage so rainwater goes where it should — away from the house.

Investigate Properly
Your engineer establishes where the blockage or fault sits — and whether it's your responsibility or the water company's — before recommending anything.

Common Drainage Problems We Fix
Sound familiar? Here's what's usually behind it — and how we put it right.
"The sink or shower drains slowly no matter what I pour down it"
Supermarket chemicals eat through the soft blockage and leave the hard build-up — fat, scale and hair — welded to the pipe wall. We clear the pipe mechanically or with high-pressure jetting so the full bore is restored, not just a hole through the middle.
"Drains gurgle and there's a bad smell inside or outside the house"
Gurgling means air is being pulled through water traps — a partial blockage or venting problem downstream. We find where the run is restricted, clear it, and check gullies and traps so the smell goes with it rather than coming back next week.
"The same drain keeps blocking every few months"
Repeat blockages almost always have a structural cause: root ingress, a bellied pipe, scale or a collapsed section. A CCTV survey shows exactly what's happening underground, so you fix the actual defect once instead of paying for clearances forever.
"An outside gully or manhole is overflowing"
When waste water backs up outside, the blockage is in the underground run — often shared with a neighbour. We establish where the obstruction sits and whose responsibility it is, jet it clear, and advise honestly if the problem lies with the water company rather than you.
