We remove all contaminated, bacteria-carrying water using powerful extraction equipment to prevent further spread and structural damage.

Deep Cleaning and Sanitisation
All affected surfaces are thoroughly cleaned and disinfected using hospital-grade antimicrobial treatments to eliminate harmful bacteria and pathogens.

Odour Removal and Deodorisation
We don’t just mask smells – we neutralise them at the source using professional deodorising techniques for long-lasting freshness.

Structural Drying and Moisture Control
We dry affected areas using advanced drying equipment to inhibit mould growth and protect your property’s integrity.

Mould Prevention and Treatment
Sewage incidents often lead to mould. We apply preventative treatments and remove any early-stage growth to ensure a safe environment.

Safety Setup and Containment Plan
Our trained technicians implement strict safety protocols, including protective equipment and containment measures, to prevent cross-contamination and ensure the area is secure before work begins.

They did a brilliant job of cleaning the site, everything has come up so much better than I expected.
The lads were very patient and alert when one of the residents were present. Even though the lads had the safety barriers up to block off the area they were working on they were still very vigilant as to who was around them.
Great lads, great job.
I would like to commend the crew who undertook the works. They were very professional at all times. They all showed great respect towards and compassion for the homeowner at all times. These 3 young men are a credit to your company and made a difficult job less difficult.

FAQs
Is sewage water dangerous?
Yes. Sewage water is highly hazardous and can contain bacteria, viruses, parasites, and toxins that pose serious health risks. Direct contact or exposure can lead to illness, which is why professional cleaning and proper protective measures are essential.
How quickly should sewage be cleaned?
Immediately. The longer sewage remains, the more it spreads into surfaces and materials, increasing contamination, odours, and the risk of structural damage and mould growth.
Can I clean sewage myself?
It’s not recommended. Sewage cleanup requires specialised equipment, protective gear, and certified disinfection methods to safely remove contaminants and prevent health risks or cross-contamination.
What does professional sewage cleaning involve?
The process includes contamination assessment, safe waste removal, deep cleaning, hospital-grade sanitisation, deodorisation, and thorough drying to restore your property to a safe, habitable condition.
Will the smell go away after cleaning?
Yes, if done right. Professional deodorisation targets odours at their source using specialised treatments, ensuring smells are fully neutralised rather than temporarily masked.
What items may need to be removed after sewage damage?
Porous materials such as carpets, underlay, insulation, and some furniture may need to be removed if heavily contaminated, as they can absorb harmful bacteria and are difficult to fully sanitise.
Can sewage damage cause mould?
Yes. Moisture from sewage incidents can quickly lead to mould growth if not properly dried and treated. Professional cleaning includes drying and antimicrobial treatments to prevent this.
Is the sewage cleaning process safe for my family or staff?
Yes. We use industry-approved, professional-grade cleaning products and follow strict safety protocols to ensure the area is safe for reoccupation once the process is complete.
Do you help with insurance claims?
Yes. We work with insurance providers and supply detailed reports, photos, and documentation to help streamline your claim process.
How long does sewage clean up take?
It depends on the extent of the contamination. Smaller incidents may take several hours, while more severe cases can take a few days, especially when drying and restoration are required.
