A sewage escape or a serious flood leaves a property looking, and often smelling, far worse than it needs to once the right people are involved. We provide sewage cleaning and flood decontamination nationwide, with a 24/7 response, for homes and businesses across England, Scotland and Wales. Our technicians attend discreetly, are fully insured, and dispose of contaminated waste through a licensed clinical-waste carrier. Request a callback or email us at [email protected] and we will talk you through what happens next.
What is sewage cleaning?
Sewage cleaning is the safe removal, cleaning and disinfection of a property after it has been affected by foul water, whether from a burst sewer pipe, a blocked drain backing up, a septic tank failure or flood water contaminated with waste matter. This category of water, often called category three or black water, carries bacteria, viruses and other pathogens, so it is treated differently from a clean water leak. The work covers extracting standing water, stripping out materials that cannot be made safe again, disinfecting everything that remains to a clinical standard, and drying the structure fully so mould cannot take hold afterwards.
When is sewage cleaning needed?
Sewage and flood contamination tends to arrive without warning, and the situations we are called out to include:
- A toilet, drain or sewer pipe backing up and releasing waste water into a bathroom, kitchen or basement.
- A burst or leaking foul water pipe inside a wall or under a floor.
- River, surface or groundwater flooding that has mixed with sewage on its way into a property.
- A septic tank or cesspit overflowing near a home or outbuilding.
- Persistent damp, staining or odour after a flood that suggests contamination was never fully dealt with.
- Commercial premises, such as a restaurant kitchen or public washroom, affected by a drainage failure.
Families and homeowners contact us directly, and we also work regularly with landlords, letting and managing agents, employers, facilities managers and councils who need a property made safe again quickly and without fuss.
How we handle it
- Assess the property to establish the extent of the contamination, the category of water involved and what materials and structural elements have been affected.
- Contain the area, sealing it off from the rest of the property to stop contaminated water, odour and airborne particles spreading further.
- Remove contaminated items and materials as clinical waste, including standing water, saturated carpet, underlay and anything else that cannot be safely cleaned.
- Clean and disinfect every remaining surface to a clinical standard using hospital-grade disinfectants suited to bacterial and pathogen contamination.
- Deodorise the property, treating the source of any lingering odour rather than masking it.
- Verify the area is safe, checking that surfaces are clean, dry and fit for the property to be used again.
- Hand over the waste documentation, giving you a clear record of what was removed and how it was disposed of.
Structural drying runs alongside this process. Once the area is disinfected, we bring in air movers and dehumidifiers and monitor moisture levels until walls, floors and timber are back to a safe reading, reducing the risk of mould developing later.
Health, safety and compliance
Sewage carries a genuine bacterial and pathogen risk, so our technicians work in full PPE throughout, including protective suits, gloves and respiratory protection appropriate to the contamination present. We follow bloodborne-pathogen and biohazard handling practices as standard, using hospital-grade disinfectants that are effective against the bacteria and viruses found in foul water. All contaminated waste is removed by a licensed clinical-waste carrier and disposed of in line with Environment Agency waste regulations, so you are not left holding any of that responsibility yourself.
What sewage cleaning typically costs
Costs vary with the size of the affected area, how many materials need to be stripped out, and how much structural drying is required, so we cannot quote a single fixed price here. As a general guide, most biohazard and contamination cleans fall in the region of £600 to £3,000. We always agree a written price with you before any work begins, and the initial assessment is free, so you know exactly what you are committing to. For a fuller breakdown of what affects the price, see our biohazard cleaning cost guide.
Is it covered by insurance?
Sewage escapes and flood damage are often covered under buildings or contents insurance, particularly where the cause was sudden, such as a burst pipe or drain failure. Every policy is different, so we would always encourage you to check the specifics with your insurer. We can liaise directly with your insurance company where helpful, providing the documentation and reporting they need to support a claim. Read more on our insurance claims page.
Why choose a professional service
Sewage and flood contamination is not something to tackle with household cleaning products and hope. The bacteria and pathogens involved pose a real health risk if handled incorrectly, and materials that look fine on the surface can still be contaminated underneath. A professional service identifies what genuinely needs to be removed against what can be safely kept, disinfects to a standard that ordinary cleaning cannot reach, and dries the structure properly so problems do not resurface as damp or mould weeks later. Doing it once, properly, with waste handled correctly from the outset, is what protects both your health and your property. We work nationwide and are ready to respond around the clock when you need us.
For contamination involving other sources of infection risk, see our infectious disease decontamination service. If a flood or sewage escape has occurred alongside a workplace incident, our industrial accident cleaning team can help. And where long-term water damage has contributed to a wider clutter or hygiene issue in a property, our hoarding cleaning service may also be relevant. To arrange an assessment, get in touch and we will take it from there.
