SOUND FAMILIAR?

Suspect a Hidden Leak in Your Haringey Home?

Hidden leaks rarely announce themselves clearly — they show up as small, easy-to-dismiss signs first. These are the patterns Haringey homeowners tell us about most.

 

Unexplained Damp or Staining

Common in Highgate and Crouch End’s period conversions, where a stain can point to a leak well away from where it appears.

Rising Water Bills

A steadily climbing bill with no change in usage is often the first sign of an underground or concealed supply leak.

Low or Dropping Pressure

A gradual pressure drop across taps can indicate a leak feeding off the mains supply somewhere in the system.

Wet Patches Outdoors

Common in Muswell Hill and Wood Green gardens — a persistently soggy patch of lawn often traces back to a split supply pipe.

What We Handle

Common Blocked Drain Needs in Haringey

Here are the drainage issues we see most often across Haringey’s mix of period houses, terraces, and flat conversions.

Urgent

Blocked sink, toilet or gully

Common across all of Haringey — same-day clearance for slow-draining or fully blocked fixtures, indoors and outdoors.

Diagnosis

Root ingress

Frequent on original clay drain runs in Muswell Hill and Crouch End, where mature street trees cause root intrusion — CCTV survey followed by root cutting or repair.

Shared drainage

Shared-drain blockages

Common in Wood Green and Tottenham flat conversions where multiple properties share a drain run — diagnosis to identify whose section is affected.

Maintenance

Grease & fat build-up

A regular issue in kitchen waste lines across Hornsey and Harringay's terraces — high-pressure jetting clears the line fully.

Survey

CCTV drain survey

Used to pinpoint collapsed sections, joint displacement or root ingress before repair — recommended for recurring blockages on older clay pipework.

Repair

Collapsed or damaged drain

Excavation and repair or relining of damaged drain sections identified by survey, most common on Haringey's older Victorian and Edwardian drain runs.
