0800 772 33 99 — we cover WV12 and WV13 from our base in Castlecroft.

Willenhall sits between Wolverhampton and Walsall and we are through it constantly, so it is one of the quicker places for us to reach. The blockages themselves are mostly a consequence of what the town used to make.

Ring us and you will get a realistic time. You speak to the people doing the work.

How we clear it

High-pressure jetting rather than rodding. In the old lock-making streets the runs are short, shallow and full of joints, and a rod pushes material from one joint to the next rather than removing it.

How high-pressure drain jetting works

Why drains fail in Willenhall

Ground conditions decide what fails in a drain and how often, and they vary street by street. Here is what we are working with.

Short-length clay, shallow and often shared. The drainage serving the older terraces here is short-length vitrified clay, shallow, and very often shared between houses – three features that each make blockages more likely and harder to attribute.

Coal underneath, and made ground on top. The South Staffordshire coalfield was worked at shallow depth here, and the industrial yards left infilled ground behind them. Both produce the same result for a drain: uneven settlement, and joints that step apart.

Post-war estates on the edges. Bentley, New Invention, Short Heath and Lane Head brought pitch fibre through the 1950s to 70s. It deforms rather than cracks, so blockages become gradually more frequent rather than arriving suddenly.

Shared runs, and arguments about them. More than most places we work, a Willenhall blockage raises the question of whose drain it actually is.

That is the reason a repeat blockage here is worth looking at properly rather than clearing again – the cause is usually structural and it is usually visible.

If it keeps happening

A drain that blocks repeatedly has a structural cause, and clearing it again treats the symptom. We can put a camera down the same run while we are on site — see CCTV drain surveys in Willenhall.

Who pays

Since 2011, shared drainage and anything beyond your boundary has belonged to Severn Trent. Willenhall has more shared runs than most of the places we cover, so this is worth settling before money changes hands – and we will tell you if the blockage is on their side of the line rather than invoicing you for it.

South Staffs Water supplies the water here but not the sewerage.

The report, and what is in it

Willenhall covers a fair spread of housing, from Bentley, Lane Head, Little London, and this applies to most of it.

A drainage site plan showing foul and storm runs, manholes, soil vent pipes and a backdrop, with distances marked between them

Written to be handed to somebody else – a solicitor, an insurer, a water authority – rather than just read once.

Each section carries a DRB grade and each observation a position in metres and a still image. Our reporting software is WRc-approved and MSCC-compliant, which matters when the report has to satisfy a third party rather than only you.

What it does not contain is a recommendations section quoting for work. We do not carry out repairs, relining or excavation, so we have nothing to sell on the back of what the camera finds. The report sets out what is there and how bad it is; what to do about it is for you and whoever does the work.

Build over agreements around Willenhall

We cover WV12 and WV13, and this comes up often enough on Willenhall property to be worth setting out properly. Bentley and Lane Head see it as much as anywhere.

A survey before the drawings are finished is considerably cheaper than a diversion after them.

You cannot normally build over an inspection chamber – access has to be maintained. The options are to redesign around it, relocate it, or divert the run under Section 185 of the Water Industry Act 1991, which obliges the undertaker to divert a sewer where it is reasonably practicable, at the applicant’s cost.

In several of the properties we have surveyed, chambers had been buried by previous landscaping. A chamber nobody knows about is the one that stops a build, so the survey records them explicitly.

We do not carry out diversions or excavation. We produce the plan and the graded report that goes with the application.

Pre-purchase surveys in Willenhall

In Willenhall – WV12 and WV13 – this is one of the questions we are asked most, and the answer is usually the same across Bentley and Lane Head.

Booked before exchange, a drainage survey is one of the cheaper pieces of due diligence available on a house purchase, and one of the few that can change the price.

You get every accessible run on camera, each defect coded to MSCC and positioned in metres, a condition grade per section, and a plan of where the drainage actually goes – which for a great many properties is the only accurate drawing that has ever existed.

Two thirds of the sections we survey come back at the top grade. A clean report is a perfectly good outcome and worth paying for: it takes drainage off the list of things to worry about, with a recording to prove it.

What actually blocks a drain in Willenhall

Bentley and Lane Head are a fair sample of Willenhall drainage, and what follows is what we find across WV12 and WV13.

Almost everything we pull out of a domestic drain falls into a short list, and most of it should never have gone down there in the first place.

Wet wipes. The single commonest cause we attend. They do not break up the way paper does, and once one snags on a rough joint the rest build against it until the bore is gone.

Nappies and sanitary items. They are designed to swell. A drain that will pass one will block on the third.

Fat, oil and grease. Poured down warm, set solid cold. On a WV12 and WV13 run with any flat section it catches everything that follows.

Roots. Not a housekeeping problem – a structural one. Roots get in through a joint that has already opened, and then behave like a net.

A pipe that is already damaged. If a run blocks repeatedly in the same place, the cause is usually the pipe rather than what went into it.

Access and site constraints in Willenhall

It varies street by street in Willenhall, but WV12 and WV13 follows a recognisable pattern and Bentley and Lane Head are typical of it.

Not every job is a clear driveway and an open chamber, and it is worth saying what we need before we arrive.

Rear access. Terraced streets often have shared entries and no vehicle access to the back. Our equipment comes off the van on foot where it has to, but it changes how long the job takes.

Finding the chamber. Covers get tarmacked over, decked over and turfed over. If you know where yours is, tell us on the phone; if you do not, we will find it, but again it is time.

Parking. On the tighter Willenhall streets, somewhere to put the van within hose reach is the practical constraint.

Standing water. The camera cannot see through it, so a blocked run is cleared before it is surveyed.
