Drain Relining Costs: The No-Dig Repair We Get Weirdly Excited About

A New Pipe, Built Inside Your Old One. Yes, Really.

Drain relining is exactly what it sounds like, and also somehow more impressive than it sounds. We feed a flexible liner, soaked in resin, into your damaged pipe. It inflates against the pipe walls, the resin cures hard, and when we pull the inflation bladder out, there is a brand-new pipe sitting snugly inside the old one. No digging. No concrete. No disruption to your driveway, your garden, or your sanity.

That process is called cured-in-place pipe lining (CIPP for short). You do not need to remember that. You just need to know it works.

We find the whole thing genuinely thrilling. You might find that strange. We find your indifference to structural pipe rehabilitation strange, so here we are.

Why Bother? What Goes Wrong With Drains in the First Place

Drains under TW-area properties take a battering. Tree roots are the classic villain, particularly around older roads in Feltham, Hampton and Twickenham where mature street trees have had decades to go exploring. Root ingress (roots growing into the pipe through cracks or joints) can partially block flow and, left alone, eventually split the pipe entirely.

Other common causes of damage include:

• Ground movement and subsidence, which shifts pipe joints out of alignment
• Corrosion in older clay or cast-iron pipes
• Collapsed sections from age or heavy vehicle loading above
• Cracked joints where pipe sections meet

A CCTV drain survey (a small camera sent down the drain to film exactly what is happening, like a nature documentary but underground and more dramatic) is almost always the first step. It tells us whether relining is viable before we quote a penny.

Drain Relining Cost: Honest Indicative Ranges

We will not give you a single fixed price here, because drain relining cost depends on pipe diameter, pipe length, depth, and access. Anyone who quotes you a flat price without surveying first is guessing. Here is what honest ranges look like:

Job type	Indicative cost range
Short residential reline (up to 3 metres)	£600 to £1,200
Full lateral reline (typical house drain run)	£1,200 to £3,000
Larger-diameter or commercial pipe	£2,500 upward, quoted on survey
CCTV survey before relining	£150 to £350 (often offset against repair cost)

Compare that to excavation. Digging up a pipe through a tiled kitchen floor, a block-paved driveway, or under a patio can add £1,500 to £5,000 or more in reinstatement costs alone, before you have paid for the actual pipe repair. Relining is not always cheaper on the drain work itself, but when you factor in what you are not destroying, it usually wins.

When Relining Works (and When It Cannot)

Relining is not a universal fix. We will always tell you straight.

Relining works well when:

• The pipe is cracked or has root ingress but still holds its basic shape
• The damage is spread across a long run rather than concentrated in one spot
• The pipe runs under something expensive or awkward to dig up
• The pipe diameter is 100mm or above (standard household drains qualify)

Relining cannot help when:

• The pipe has completely collapsed, leaving no shape to line against
• There is a severe misalignment (a pipe joint that has shifted so far it creates a step)
• The pipe is too narrow or has bends too tight for the liner to negotiate
• The access points (manholes or inspection chambers) are too restricted

In those cases we will tell you excavation is the right call. We would rather give you that news clearly than sell you a reline that will not last.

The Process, Step by Step

1. CCTV survey. We send the camera down, record the footage, and show you exactly what we found.
2. Drain clean. We jet-wash the pipe (high-pressure water clears roots, scale and debris) so the liner bonds to a clean surface.
3. Liner installation. The resin-soaked liner goes in, is inflated against the pipe walls, and cures. Curing time varies by product and temperature, typically two to four hours.
4. Post-reline CCTV check. We send the camera back down to confirm the liner has seated correctly and the pipe is clear.
5. Done. You have a pipe with a design life of 50 years or more.

Serving Feltham, TW13 and Across the TW Postcode Area

We cover Feltham, Ashford, Hanworth, and the wider TW area around the clock. If your drain survey reveals damage, we can usually schedule relining within a few days, or faster for urgent cases.

If you are dealing with an active blockage alongside suspected pipe damage, we can attend as an emergency, clear the blockage, survey, and advise on relining in a single visit where access allows.

Drain relining is one of those repairs that, done properly, you genuinely forget about. The pipe does its job quietly for decades and you never think about it again. That is exactly what a good drain repair should do.

If you have a cracked or damaged drain, or you want a CCTV survey to find out what is actually going on underground, call us any time on 07700 137648. We are available 24 hours a day, seven days a week, across the TW postcode area.
