Sewage Emergency across London

Sewage backing up into your London home is a health emergency as well as a drain problem. Raw sewage carries harmful bacteria, so it needs safe handling and containment.

Acting fast limits the damage. Bacteria soak into carpet underlay, plasterboard and timber skirting the longer sewage stands. Quick action also limits the cost of cleaning up later.

Our engineers come equipped for sewage backups. We clear the blockage and advise on safe cleaning of the affected areas. Engineers wear protective gear for these jobs.

We can also advise where the backup starts in the public sewer network. We provide CCTV evidence to support a claim for costs against Thames Water. Health and safety come first, though. We clear the blockage, isolate the affected area and advise whether the home is safe to stay in until professional cleaning is done.

Keep children and pets away from the affected area while you wait. Since sewage can spread on shoes and hands, wash well after any contact. Although the mess looks bad, the first job is always to stop the flow and keep everyone safe.

Sewage Emergency — frequently asked questions

What should I do immediately if sewage backs up in my London home?

Stop using all water in the property, because every flush or tap sends more sewage into the blocked system. Lay towels to hold back the overflow. Open windows for fresh air. Then request a quote online straight away. Do not clean up sewage yourself without proper protection, since it is a health hazard. Our engineer will clear the blockage and advise on professional cleaning if needed.
