Urgent response to sewage backups and overflows — compliant with Thames Water regulations.
Free, no-obligation — we'll call you back fast.
Sewage backup into your London home is a health emergency as well as a drainage emergency. Raw sewage carries harmful bacteria and requires safe handling and containment. Furthermore, the longer sewage stands inside a property, the further bacteria penetrate porous materials such as carpet underlay, plasterboard, and timber skirtings, so a fast response directly limits the eventual decontamination cost. Our emergency team is equipped and trained for sewage backup situations — we clear the blockage fast and advise on safe decontamination of any affected areas. In addition to clearing the immediate cause, we engage Thames Water on your behalf where the sewage backup originates in the adopted sewer network. Therefore, you are not left navigating water-company processes during what is already an extremely stressful incident, and any cost-recovery claim is supported by professionally prepared evidence. As a result, customers in shared-drainage London terraces frequently recover their full clearance and decontamination costs from Thames Water, even where the initial response was paid privately. That said, we always prioritise health and habitability first — clearing the blockage, isolating the affected area, and advising whether the property is safe to remain in until professional decontamination is complete. Our engineers wear full PPE for sewage incidents and carry biocide treatments for initial site stabilisation before specialist cleaners arrive.

Sewage emergency call-outs are priced on arrival. We aim to resolve sewage emergencies at the standard clearing rate — not at inflated emergency prices. We will always quote before starting work.
Stop using all water in the property — every flush or tap usage will send more sewage into the backed-up system. Lay towels to contain the overflow. Open windows for ventilation. Call us immediately on 020 3900 0030. Do not attempt to clean up sewage yourself without appropriate protection — it is a health hazard. Our engineer will resolve the blockage and advise on professional decontamination if needed.
