The material your drain is made of decides how it blocks — and what will safely clear it.
Modern plastic drainage is smooth-bored and forgiving. Blockages sit in it rather than adhering to it, and it tolerates rodding and jetting comfortably.
Cast iron doesn't. It corrodes from the inside, developing a rough, scaled interior that catches everything passing — so it blocks progressively at points that get worse each time. And a heavily corroded cast iron line can be damaged by aggressive clearing, which is a genuine consideration rather than a caution.
Clay drainage is common on older properties and fails at the joints — which is exactly where roots enter.
And older properties frequently have all three, spliced together across decades of alterations.
Which means the right method isn't a matter of preference. It's a matter of what the pipe can take and what the blockage actually is.
Getting that wrong either fails to clear it or damages the line.
Tell us roughly when the property was built. It narrows both before anyone arrives.

Plastic spliced into cast iron, or a modern extension joined to a clay run — and the transition point is where blockages start.
Effective at breaking through. Fine in plastic and sound clay. Used carefully in older cast iron, where the interior is already compromised.
Scours the full internal diameter — the correct method for grease, sludge, and scale. Excellent in plastic and sound pipe. Pressure moderated in fragile cast iron, which is a judgement rather than a fixed setting.
Chains or specialist heads removing hard scale from cast iron and clay, restoring diameter lost over decades. Frequently the actual answer in an older property.
For growth entering through joints or cracks. Cutting clears it; sealing the entry stops it returning.
In older properties, the one that establishes what the pipe can take before anyone applies pressure to it.
Where the pipe has failed.
Where the blockage sits in a public sewer or a shared drain, the responsibility and the cost may not be yours. Neighbouring properties affected at the same time is the clearest signal.
A smooth pipe passes ordinary waste. A rough, scaled, or corroded one catches it — and once something catches, everything behind it collects. So blockages in older drainage recur at the same points, because the roughness that caused it is permanent until it's removed.
The rough surface is still there.
It works on the pipe as well as the blockage.
Which is the difference between clearing and fixing.
Cracked or displaced sections need repair or lining.
Which is why a camera matters more in an old property than a new one. The pattern of repeat blockages tells you something is there. The camera tells you what, and whether the pipe can take clearing at all.
The dominant cause in any kitchen — and the rough interior gives it something to adhere to.
And old cast iron is entirely made of imperfections.
The defining finding in older cast iron.
The classic older-property external finding.
Or original laying.
A repair rather than a clean.
New drainage laid too level to self-clear.
The bore or alignment changes, and waste collects there. Plus hair bound with soap residue, in the trap or the first metre, in any property.
If a drain is fully blocked, stop putting anything into it — water included.
In old drainage that's usually condition, not habits — and the camera settles it.
Establishing what the pipe can take.
Drainage faults are expensive, invisible on a standard survey, and entirely negotiable before exchange.
Knowing what's under the ground and what condition it's in.
Located, so the entry point can be sealed rather than just cut.
Footage, a located position, and a recommendation you can act on.
Not worth it on a first-time blockage in one fixture that cleared cleanly, in any property.
Because cast iron, clay, and plastic block differently and tolerate clearing differently.
In older cast iron, scale is usually the actual problem — and removing it restores the bore rather than punching through it.
Heavily corroded cast iron can be damaged by aggressive clearing, and that's worth knowing first.
Plastic spliced into cast iron, extensions joined to clay runs — the transitions are where we look.
Grease is a habit. Scale, roots, and corrosion product are pipe condition — and that's a different conversation.

Cast iron corrodes from the inside and develops a rough interior that catches everything passing — so it blocks repeatedly at the same points, and heavily corroded sections can be damaged by aggressive clearing.
Roughly, from the property's age. Older houses commonly have cast iron soil stacks and internal waste with clay external runs. Newer ones are plastic throughout. Many older properties have all three, spliced together across decades of alterations — and the transitions are where blockages start.
In older drainage that's usually condition rather than habits. A rough, scaled, or corroded interior catches waste, and the roughness is permanent until it's removed. Clearing punches through; descaling restores the bore.
Chains or specialist heads removing hard scale and corrosion product from cast iron and clay, restoring diameter lost over decades. It's frequently the actual answer in an older property, and it's rarely offered — most contractors rod and move on.
Heavily corroded cast iron is fragile, and pressure has to be judged accordingly. That's a reason to assess condition first rather than a reason to avoid jetting — which is exactly what a camera establishes before anyone commits.
Yes. They generate heat, and older cast iron, clay, and aged seals tolerate that considerably less well than modern plastic. A resulting leak in a buried or concealed old line costs far more than the blockage did.
Clay is sound in the middle and vulnerable at the joints. Roots find moisture through joint failures and hairline cracks, then grow inside where conditions suit them. Cutting clears the growth; sealing the entry point stops it returning.
Frequently because the new drainage was laid too level to self-clear. Inadequate falls mean it blocks because it was built that way — no amount of clearing changes it, and the fall needs re-laying.
No. One fixture affected with everything else normal is local — usually the trap — and it books at ordinary rates whatever the property's age.
The problem is in the main run rather than at any fixture. Water rising escapes through the lowest opening. Stop running water and call.
Genuinely worth it. Knowing what's under the ground, what it's made of, and what condition it's in is far cheaper before the work than after a new patio is down.
Yes — including descaling, root cutting, and the condition assessment that decides which method a line can safely take.
Drains don't all block the same way. Smooth plastic passes what rough cast iron catches, clay fails at its joints where plastic fails at its falls, and an older property frequently has all three joined together. The method that clears one can be wrong — or damaging — for another.
American Plumbing Experts asks what the drainage is made of, descales where scale is the actual problem, assesses condition before applying pressure to fragile pipe, and tells you plainly whether it's habits or the line itself.
