Symptoms

Signs you have a drainage problem

Spotting the early signs saves money. Each of these symptoms is a reason to call a qualified engineer before it becomes an emergency.

⚠️ Slow-draining sinks, baths or showers

Early warning. Easier to clear at this stage. Usually hair, soap-scum, or FOG. £95 inc VAT typical.

⚠️ Gurgling sounds from drains when other plumbing is used

Air being pulled past a partial blockage. The system is fighting itself. Don't ignore.

⚠️ Sewage smells inside the property

Failed waste seal, dried-out trap, or a venting problem. Sometimes a partial blockage in the soil stack.

⚠️ Manhole or inspection chamber overflowing

Critical, the run between your property and the public sewer is blocked or collapsed. Same-day response needed.

⚠️ Sewage backing up into the lowest fixture (basement WC, ground-floor shower)

Severe blockage downstream. Don't flush anything until cleared, you'll worsen the backup.

⚠️ Lush green patch of grass over a drain run

Often indicates a leaking drain irrigating the soil. CCTV survey to locate the defect before subsidence becomes the next problem.

⚠️ Repeated blockages in the same drain

There's a structural defect, dropped joint, fracture, root ingress. Clearing alone won't fix it. CCTV needed.

⚠️ Recent subsidence or cracking near drain runs

Could be cause or effect of a drainage failure. Insurance-grade investigation often warranted.

How we work

Our drainage engineer process.

No surprises, no “I'll need to come back tomorrow”. This is the exact path every drainage job follows.

  1. Symptom captured + property typeWe bring the right kit, domestic drains differ from commercial soil stacks differ from public-sewer connections.
  2. Engineer dispatched with jetter, rods and CCTVSingle van, single visit, all the diagnosis and most of the repair in one go.
  3. Initial diagnosis, rods first, CCTV if neededOften a clearance is enough. When we suspect structural damage we run the camera before quoting repair.
  4. Quote in writing, clearance vs repairClearance only, or full no-dig repair? You decide. Both options quoted on site.
  5. Clearance carried out + verificationWe don't sign off until water flow is fully restored and any debris is contained or removed.
  6. CCTV verification of clearanceOn request, recorded footage emailed to you. Insurance and managing-agent grade.
  7. Defect list and recommendationsWhere structural defects are found, we document them with WRc codes and quote the repair separately.
  8. 12-month workmanship guaranteeOn clearances and repairs alike.

London context

Drainage in London: what makes it different.

London's drainage infrastructure is uniquely complex and our engineers know it intimately.

Victorian sewers. Much of central London still uses the original Bazalgette-era sewer network from the 1860s. Egg-shaped brick combined sewers (foul + surface water) running under streets and gardens. Repair requires specialist methods.

Combined vs separated systems. Most inner London is on a combined system (rain + foul in one pipe). Outer London (1930s+) typically has separated systems. This affects how blockages and surcharges manifest, and what insurers will and won't cover.

Build-overs and extensions. Building over or near a public sewer requires a Build-Over Agreement from Thames Water. We provide the CCTV survey and structural report needed for consent.

FAQ

Drainage: your questions

How fast can a drainage engineer reach me?
Typical response across the M25 is 30 to 60 minutes, often faster in inner London, subject to engineer availability and traffic. Live dispatch, never queued. Times quoted are best-effort targets, not contractual guarantees.
How does drainage pricing work?
Labour is one flat rate across London and the M25, billed per 30 minutes: from £75 / 30 min (daytime) up to £147 / 30 min (nighttime), with a one-hour minimum then 30-minute increments. There is no callout fee. Domestic prices shown inc VAT, no hidden extras (no parking, fuel, ULEZ or Congestion Charge surcharges). The engineer converts to a fixed-price quote on site after diagnosis where the scope is clear. Materials at trade cost plus 30%, itemised on the invoice. Full rate card.
Do you charge to come out and look?
There is no callout fee, ever. For pre-planned bookings the one-hour minimum labour charge starts when the engineer begins on-site work. For 24/7 emergencies you pay only for the labour at the rate for the time of day, plus any materials. Non-emergency reschedules are free with at least 24 hours' notice.
Are you Gas Safe registered?
Yes. Gas Safe Register number 972173. Verifiable live at gassaferegister.co.uk using that number or any individual engineer's ID.
Do you guarantee the work?
Every job carries a 12-month workmanship guarantee. If something fails inside 12 months for the same fault, we come back at no charge.
