Standing water in the sink, gurgling toilets or a manhole that's overflowing onto the patio — we clear it the same day with high-pressure jetting and a camera survey to prove the run is fully clear before we leave.

Drain unblocking — sinks, toilets, outside gullies
Whether it's a slow kitchen sink, a toilet that won't flush properly or a manhole backing up into the garden, the first job is to identify which run is actually blocked. We trace the system from the inside out, find the affected length and clear it from the right access point — not the easiest one.
For internal blockages we use professional drain rods, electric augers and chemical drain cleaners only when appropriate. For external runs we use a 4,000 PSI jet-vac with the correct nozzle for the pipe diameter — flat-jet for grease, root-cutter for invading roots, descaler for scaled cast-iron sections.
Every external job ends with a CCTV survey down the cleared run. You see the inside of your own drain, on screen, before we leave. If we find anything that needs a follow-up — collapsed section, displaced joint, root ingress — you get the recording, a quote, and zero pressure to use us for the repair.
What happens if you wait
A blocked outside drain is the polite version. The impolite version is sewage coming back up the lowest fixture in the house — usually a downstairs WC or shower tray — at the worst possible moment.
Caustic-soda pours and 'one-shot' supermarket drain cleaners can clear a fatberg short-term, but they damage older cast-iron pipe and don't touch root ingress at all. Worse, they leave the cause in place.
Our process
We work out whether the blockage is on a single fixture, a stack, or the main run to the sewer — by trace, not by guess.
Manhole lift, rodding eye, or under-sink trap. We pick the access that gives us the best angle, not just the closest.
Rods, electric auger or 4,000 PSI jet-vac with the appropriate nozzle for grease, scale or roots.
Camera the cleared run end-to-end. You see what's inside your drain, on screen.
Written report on what caused it, what's clear, what (if anything) needs follow-up. 12-month workmanship guarantee.

We don't charge a separate fee to bring the equipment. The price covers everything.
Standard, not an add-on. You see what was wrong and what's now clear.
If the same cause re-blocks the same run inside 12 months, we re-clear it free.
Rods, augers, jet-vacs and chemical descalers — we use what fits the job.
If your drain needs a relining or a section replacement, we tell you. If it doesn't, we tell you that too.

In detail
Roughly two-thirds of the blockages we clear in Northamptonshire fall into three buckets: kitchen-grease build-up in the kitchen branch, root ingress at the joint where the soil run leaves the property, and wet-wipe stacks in the main run downstream of upstairs toilets. Each needs a different clearing method, and each has a different probability of returning.
Kitchen-grease blockages are usually softening and flushing jobs — hot water and a flat-jet nozzle will move them, but the long-term fix is a pour of bio enzyme weekly. Root ingress is mechanical — only a root-cutting jet-vac nozzle or a mechanical chain flail will deal with it properly, and even then the joint will reseed within 12–24 months.
Wet-wipe and 'flushable' wipe blockages are the fastest-growing category we see — 'flushable' is a marketing word, not a drainage standard. Once a wipe pad has formed in a 100mm soil pipe, only a high-pressure jet will break it down. A chemical pour will not.
Grease, food and detergent scale. Cleared with hot water + jet, prevented with weekly bio-enzyme.
Wet wipes, sanitary, build-up at bend below pan. Jet-vac clearance, not chemicals.
Leaf litter, silt, root ingress at joints. Jetted from manhole upstream, surveyed downstream.
Roots, fat-bergs, displaced joints. Heavy-duty jet, CCTV, then quote on lining if needed.
Scaled internal bore. Descaling chain or descaler nozzle, not caustic chemicals.
Root ingress, pipe deformity or fall problem. We find the root cause, not just clear the symptom.
