Blocked Drains in Hitchin
Blocked drains, broken pipes and root damage across SG4 and SG
A lot of Hitchin’s drainage runs through ageing clay pipework laid 80, 100, even 130 years ago. We get more callouts in this town for root ingress through cracked clay joints than for almost anything else; particularly in the Victorian and Edwardian terraces around the Market Place and Bedford Road, where mature trees in front gardens and along the streets have spent decades sending fine roots into any pipe joint that’s lost its seal. The other big culprit is grease and wet wipes building up in 1960s estate runs across Westmill and Purwell that were never sized for modern household waste.
Drain unblocking, CCTV surveys, drain repairs and no-dig drain lining, full drainage service across Hitchin.
Why Hitchin drains block more often than newer-built areas
Three factors. First, the original Victorian and Edwardian drainage was laid in salt-glazed clay with mortared joints, beautiful workmanship at the time, but the joints fail with age and root pressure. Second, Hitchin has more mature trees per street than most Hertfordshire towns, and tree roots actively seek out the moisture and nutrients leaking from a failing joint. Third, the wider drainage runs through a chalk subsoil that holds water and slows flow, so any partial blockage builds up faster than it would in sandy soil.
All of which means: when your kitchen sink starts gurgling, the toilet is slow to flush, or you smell drainage outside, it’s worth investigating sooner rather than later. Small problems become big ones quickly in Hitchin’s older drainage.

Our drainage services
Drain Unblocking
High-pressure jetting, drain rods, and electro-mechanical cutters as needed. Everything in the van, 90% of blockages cleared within the first hour. No call-out fee in hours, fixed price before any work.
CCTV Drain Surveys
Colour CCTV cameras pushed through the drain runs, with a recorded report and a written summary of what we found. Standard for pre-purchase surveys, insurance claims, recurring blockage diagnosis, and identifying root ingress before it gets worse.
Drain Repairs
Excavation and replacement where pipe collapse or severe damage is found. We minimise excavation footprint by tracing the exact damage location with CCTV first, then opening only the section needed.
Drain Lining
No-dig repair of damaged drains using a resin-impregnated liner cured in place. Ideal for Hitchin properties where a traditional dig would mean lifting a driveway, patio, or coming up through the kitchen floor, saves thousands on reinstatement costs and finishes in a day.
The drainage problems we see most often around Hitchin
Root ingress in Victorian terraces
Fine roots enter through clay joint failures, then expand year after year until they form a mat that catches everything passing through. CCTV identifies the exact location, then either electro-mechanical cutting (short-term fix) or drain lining (long-term repair) sorts it. We always recommend a long-term repair where roots have already established.
Grease blockages in older estates
Westmill, Purwell and parts of Bearton have drainage that was sized for 1960s households - not modern dishwashers, washing machines and the cooking grease they produce. High-pressure jetting clears existing blockages; we usually recommend an annual maintenance visit to prevent recurrence.
Wet wipe and 'flushable' product blockages
These are not flushable, regardless of packaging claims. They form fatberg-style blockages in soil pipes, particularly in flats above the High Street and converted properties with shared drainage. Mechanical cutting is usually the only reliable way to clear them.
Collapsed clay pipes in village properties
Pirton, Offley, St Ippolyts and the surrounding villages have older shared drainage runs that have sometimes collapsed under tree pressure or ground movement. CCTV survey first, then either spot excavation or full lining depending on the extent.

FAQs
How quickly can you get to a blocked drain in Hitchin?
For genuine emergencies (sewage backing up, every toilet blocked, water pooling), within 1 to 2 hours, 24/7. For non-urgent slow drains, usually same-day or next-morning.
How much does drain unblocking in Hitchin cost?
Most domestic blockages are cleared for £120 to £180 fixed price including the call-out, no per-hour charges that creep up. Larger or more complex blockages requiring CCTV diagnosis or extended jetting are quoted in writing before any work starts.
Can old clay pipework in Hitchin actually be repaired without digging?
In most cases, yes, using cured-in-place drain lining. We feed a resin-impregnated liner into the pipe, inflate it against the inside of the original clay, and cure it with hot water or UV. The result is a smooth, jointless plastic pipe inside the original clay. Lasts 50+ years and avoids excavating driveways.
Do you handle blocked toilets and sinks too, or just outside drains?
All of it. Internal soil pipes, kitchen and bathroom waste runs, external gullies, manholes, mains drainage. One team handles the whole job, we don’t subcontract drainage to anyone.
My drains keep blocking every few months, what's actually wrong?
Almost always a structural issue rather than a behavioural one. Root ingress, partial collapse, or a section with insufficient fall. CCTV will identify the cause within an hour. Once the underlying issue is fixed, the recurring blockages stop.
Will my insurance cover drain repairs in Hitchin?
Most home insurance policies cover sudden drain collapse and root damage to private drainage on your property. They typically don’t cover gradual wear or maintenance. We provide CCTV reports and quotes formatted for insurance claims and can liaise directly with your insurer.

Blocked basins and sinks in Hitchin
A basin that drains slowly is almost always a build-up inside the trap or the short waste run behind it, rather than a fault in the main drain. Soap, toothpaste and hair bind together in the bend and narrow the bore until water backs up. In kitchens the culprit is fat and grease, which cools on the pipe wall and sets hard.
We clear the trap first and check the run into the stack before assuming anything further down is at fault. If the basin clears and the problem returns within weeks, the blockage is usually further along the branch, and that is when a camera earns its place rather than more plunging.
Drain repairs and gutter work in Hitchin
Hitchin has a lot of clay pipework laid between the 1890s and the 1930s. Clay joints were originally sealed with mortar, and once that mortar fails the joint becomes an entry point for tree roots. Repairs range from a localised patch liner at a single failed joint through to relining a full length, and the right answer depends on what the survey shows rather than on a guess made at ground level.
Guttering matters here for the same reason. A blocked or split gutter pushes rainwater down the wall and into the ground directly against the foundations, which saturates the soil around older drain runs and accelerates joint failure. Clearing gutters is cheap; the damage caused by leaving them is not.
CCTV drain surveys in Hitchin
A CCTV survey puts a camera through the drain so the actual condition of the pipe is visible rather than inferred. It is the right step when a drain blocks repeatedly, when there is standing water with no obvious cause, before buying a property, or when an insurer needs evidence of what failed and where.
The survey shows the material, the diameter, the position of every joint and connection, and the exact distance to any defect. That distance matters, because it is the difference between excavating one square metre of a driveway and digging up the length of it.
