Drainage Services in Stevenage
Blocked drains, broken pipes and root damage across SG1 and SG2
Drainage in Stevenage splits sharply into two stories. Old Town has the same kind of ageing salt-glazed clay pipework you’d expect from any pre-war English town – mortar joints failing, root ingress from mature trees, the usual century-old problems. The New Town estates are different. They were built rapidly between the early 1950s and the late 1960s, often with pitch fibre drains (a tar-impregnated wood fibre pipe that was cheap, quick to install and turned out to deform internally within 30 years), and with shared drainage runs that serve clusters of houses on the same estate spur. When those go wrong, they go wrong for half a street at once.
Drain unblocking, CCTV surveys, drain repairs and no-dig drain lining – full drainage service across Stevenage.
Why Stevenage drainage causes the headaches it does
The post-war housing boom in Stevenage prioritised speed of build over long-term durability of buried services. That was a perfectly reasonable choice in 1953 when families urgently needed homes – but seventy years on, the consequences are showing. Pitch fibre drains laid in some of the earliest New Town estates have deformed internally to an oval shape, which catches solids and creates recurring blockages no amount of rodding will permanently solve. Shared drainage runs between properties mean a blockage in one house can back up into a neighbour’s. And the surrounding clay subsoil holds water and slows flow, so any partial blockage builds up faster than it would in sandy ground.
The good news: most of these problems are now fixable with no-dig drain lining, which avoids the cost and disruption of excavating driveways and gardens.

Our drainage services
Drain Unblocking
High-pressure water jetting, drain rods, and electro-mechanical cutters as the job needs. Everything in the van, 90% of blockages cleared within the first hour. No call-out fee - fixed price before any work starts.
CCTV Drain Surveys
Colour CCTV cameras pushed through the drain runs, with a recorded report and written summary. Standard for pre-purchase surveys, insurance claims, recurring blockage diagnosis, and identifying pitch fibre deformation or 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.
Drain Lining
No-dig repair using a resin-impregnated liner cured in place. Particularly relevant for Stevenage's pitch fibre drains - lining provides a smooth plastic pipe inside the deformed original and prevents future blockages without lifting driveways or patios.
The drainage problems we see most often around Hitchin
Pitch fibre drain deformation on early New Town estates
A specific Stevenage problem. Pitch fibre was used widely in the earliest 1950s estate housing. Over time it deforms internally into an oval or pear shape that traps everything passing through. Mechanical clearance gives temporary relief; only relining or replacement gives a permanent fix. CCTV identifies whether you've got pitch fibre or clay quickly.
Shared drainage backups between properties
Common across the older New Town estates where adjoining houses share spur runs to the main sewer. If your toilet starts backing up at the same time as your neighbour reports the same issue, the blockage is in the shared section. We trace it with CCTV and coordinate with neighbouring residents where needed.
Root ingress in Old Town clay drains
The Victorian and Edwardian properties around Stevenage Old Town have the same root-and-clay-joint problems as any older town. Mature trees on the High Street and surrounding streets send fine roots into any joint that's lost its seal.
Grease and wet wipe blockages
Particularly common in flats above the High Street and the converted properties where multiple households share waste runs. Wet wipes are not flushable, regardless of packaging claims. Mechanical cutting is usually the only reliable way to clear them.

FAQs
How quickly can you get to a blocked drain in Stevenage?
Genuine emergencies (sewage backing up, every toilet blocked, water pooling) – within 1–2 hours, 24/7. Non-urgent slow drains, usually same-day or next-morning.
How much does drain unblocking in Stevenage cost?
Most domestic blockages cleared for £120–£180 fixed price including the call-out. Larger or more complex blockages requiring CCTV diagnosis or extended jetting are quoted in writing before work starts.
What is pitch fibre drain - and how do I know if I've got it?
Pitch fibre is a tar-impregnated wood fibre pipe used widely in 1950s and 60s housing, including across Stevenage’s New Town estates. It deforms internally over time, causing recurring blockages. CCTV survey identifies it within minutes. If you’ve got it and you’re getting recurring blockages, relining usually solves it permanently.
My drains keep blocking every few months - what's actually wrong?
Almost always a structural issue rather than a behavioural one. Pitch fibre deformation, root ingress, partial collapse, or a section with insufficient fall. A CCTV survey identifies the cause within an hour. Once the underlying issue is fixed, the recurring blockages stop.
Can old drainage in Stevenage be repaired without digging up the garden?
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, and cure it. Result: a smooth, jointless plastic pipe inside the original. Lasts 50+ years and avoids excavating driveways.
Will my insurance cover drain repairs in Stevenage?
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.
