Drain Descaling

Old pipes running slow? Restore original flow — without replacement.

Cast iron soil stacks and old concrete sewer runs build up scale and rust that gradually restricts flow. Descaling with mechanical chains and controlled jetting strips the pipe back close to its original bore — extending its serviceable life by decades without expensive replacement.

Warning signs

  • Slow flow in older cast iron soil stacks
  • Recurring blockages in a specific vertical run
  • CCTV showing heavy scale or tuberculation

Common causes

  • Age-related build-up in cast iron pipework
  • Hard-water scale in mains fed drainage
  • Poor pipe falls encouraging deposits
Our process

How we handle drain descaling

01
CCTV survey
Confirms scale build-up and pipe structural condition.
02
Mechanical descaling
Chain flails or specialist cutters restore the bore.
03
Jet flush
Debris flushed clear and discharged responsibly.
04
Post-work CCTV
Clean pipe verified and reported.

Kit we bring

  • Chain de-scaling heads
  • Precision cutters
  • High-flow jetter for flush
  • Post-work CCTV

While you wait — do

  • Descale before considering full replacement — often extends life 20+ years

Please don't

  • Don't descale visibly cracked pipes — they may collapse under the process

Common questions

Is descaling safe for old pipes?
Yes if the pipe is structurally sound. We always survey first to check.
