Internal Drain Unblocking across London

Internal drain unblocking covers all the drains inside the house. That means kitchen sinks, bathroom drains, toilets, soil pipes and internal gullies. Problems range from a simple trap blockage to a deep one in the soil pipe.

In converted period homes and high-rise flats, several units often share one soil stack. A symptom in your kitchen or bathroom may therefore start two floors below. We carry the kit to diagnose and clear blockages at every level.

Some flats have no outside manhole. In those cases, we use a compact through-toilet CCTV camera to find the fault. Even a fifth-floor flat or a basement studio can be diagnosed without opening ceilings in the flat below.

Where the fault lies in shared pipework, we give you written evidence to send to the freeholder or managing agent. The repair duty then lands in the right place. We lay floor protection and clean up after the visit.

We explain what we find as we go. Because internal drains vary from home to home, no two jobs are alike. While we work, we tell you the cause and what to do next. You then know how to avoid a repeat blockage.

Signs you need internal drain unblocking help

  • ✓ Kitchen, bathroom, or utility drain running slowly or fully blocked
  • ✓ Toilet not clearing properly
  • ✓ Drain gurgling when water is used elsewhere in the house
  • ✓ Multiple internal drains affected at the same time
  • ✓ Sewage smell from an internal drain

Our process

  1. 1. Identify which drains are affected and to what degree
  2. 2. Start at the furthest accessible point from the sewer
  3. 3. Clear trap-level blockages mechanically
  4. 4. Use rods or jetting for blockages in pipes beyond the trap
  5. 5. Test all affected drains are flowing correctly
  6. 6. Advise on cause and prevention

Pricing guide

Prices vary because every job differs. Internal drain unblocking depends on the job. A standard blockage costs less than one deep in the soil pipe that needs jetting. Request a quote online, and we confirm the price with you before any work starts.

Internal Drain Unblocking — frequently asked questions

Can you unblock my London flat's internal drain without access to the outside?

Yes. We can usually reach a blockage from inside the flat, either through the toilet with a CCTV camera or from internal access points. We often work in flats that have little outside access.
