Service overview
Drainage & Drain Jetting: what it is and when you need it
What it is
Drainage work covers clearing blockages from waste pipes and underground drains, high-pressure water jetting to scour pipes clean, and drain surveys to see inside pipes and identify damage or recurring causes.
Who it's for
Homeowners, landlords and anyone with slow-draining sinks, baths and toilets, overflowing gullies or manholes, or recurring blockages.
When you need it
Call us when water drains slowly, gurgles, backs up in a gully or manhole, toilets rise when flushed, or there's a persistent drain smell inside or outside.
Why professional help matters
Chemical cleaners and plungers often only move a blockage further down. Jetting clears the pipe wall properly, and a survey shows whether there's a structural issue that will cause the blockage to return.
The cost of waiting
What happens if it's ignored
Blocked drains can overflow sewage into gardens, driveways or inside the property: a serious hygiene problem and costly clean-up.
Repeated blockages often point to damaged pipes, root ingress or a collapse. Left alone, these get worse and more expensive.
Standing wastewater attracts pests and creates persistent odours.
Common mistakes we see
- Pouring fat, oil and grease down the kitchen sink.
- Flushing wet wipes, even ones labelled 'flushable'.
- Using caustic chemicals repeatedly, which can damage pipes and seals.
- Treating a recurring blockage without surveying the drain.

In detail
Drainage & Drain Jetting explained
High-pressure drain jetting
Jetting uses a hose and nozzle driving water at high pressure into the drain. Rear-facing jets pull the hose along while scouring the pipe; forward jets break through the blockage. It removes grease, silt, scale and debris that rods alone leave behind.
Drain surveys
A drain survey uses a camera to inspect inside the pipe. It shows cracks, displaced joints, root ingress, collapses and build-up, and is the best way to understand recurring blockages or check drains before buying a property.
Internal waste pipes and soil stacks
Not every blockage is underground. Sinks, baths, showers and toilets can block in internal waste pipes and soil stacks. We also replace old waste and soil pipework, including removing old cast iron soil stacks and replacing them with modern plastic, a job a customer in Yell reviews described in detail.
Why homeowners choose J&L
J&L Plumbing and Heating Limited is owner-run and based in Pinner, led by Jack Webster, who has 24 years of experience in the plumbing trade. There is no call-out charge, every job is quoted free on site, and we're open 24 hours. Customers regularly mention fast response, honest advice, fair pricing and tidy, punctual work, and many use us again and again.
Pricing, quotes and payment
Because every drainage & drain jetting job is different, we don't guess prices over the phone. We come out with no call-out charge, look at the job properly and give you a free quote on site before any work begins, so you decide with the full price in front of you, not after the bill arrives. Once the work is done and tested, you can pay by card on our card machine, in cash or by bank transfer. We're fully insured with public liability cover, and if something needs attention beyond the original job, we'll explain it and quote it separately rather than simply adding it on.
What to expect on the day
Customers regularly tell us the same things about the visit itself: we turn up when we say we will, explain what we've found in plain English, suggest the practical option rather than the most expensive one, and leave the area clean and tidy. Customers often mention Jack and Lawrence by name in their reviews.
