We are a family-run firm covering London since 2013, and N4 is inside our core coverage. It includes Finsbury Park, Manor House and Stroud Green.

What we cover in N4

The area we cover in N4 spans Finsbury Park, Manor House and Stroud Green, in Islington and Haringey. Because we cover the neighbouring postcodes too, a run crossing a boundary needs only one contractor.

Finsbury Park and Stroud Green mix Victorian terraces with post-war estates. Conversion density is high, so a single original drain run frequently serves several kitchens and bathrooms.

Common causes in N4

Nearly everything we clear in N4 comes down to a short list:

  • A restriction that has been forming for months, finished off by one heavy load
  • A defect in the pipe itself holding back solids
  • A common drain serving more than one home
  • Surface water overwhelming a combined sewer

Signs worth reporting

The symptoms worth reporting when you ring:

  • Water sitting in a drain outside hours after the last discharge
  • Several fittings draining slowly at once, which points at the shared run
  • Gurgling from a toilet or sink when the bath is let out
  • A sour smell near the gully that is stronger in warm weather

How the visit works

We work to the same order on every visit, which is how we can quote a fixed price:

  1. Make the property safe on arrival
  2. Trace the restriction by working through the chambers
  3. Remove the obstruction with jetting or rods
  4. Explain the cause and whether the pipe needs more than clearing

Before we arrive

What to do before we get there:

  • Keep water use to nothing, particularly appliances on a timer
  • Move children and pets away from the affected area
  • Clear access to the drain covers if you can
  • Note which fittings are affected so we arrive prepared

Who pays for the repair

Whose pipe it is matters as much as what is in it. Since 2011, most shared drains and lateral drains in England belong to the water company, and a defect on the shared run is not your cost. We identify the location and are straight with you about it, even when that means we are not the ones doing the repair.

What it costs in N4

Drain unblocking starts at a fixed £120 plus VAT, with no call-out charge at any hour. You get a fixed figure rather than a running clock, so nothing changes once we are on site.

Frequently asked

Stop using water in the property, including washing machines and dishwashers, and keep people away from any standing waste water.

Our average response is 75 minutes, and we are typically 60 to 90 minutes from any address in {N4}. We give you a realistic time on the call rather than an optimistic one.

No. We never charge a call-out fee, at any hour, on any day of the year. You get a fixed price for the work itself before anything starts.
