Sewage Cleanup
A sewage backup is a category-3 biohazard. We seal it off, run negative air, remove it safely, and disinfect your home back to healthy.

Sewage Cleanup, explained
A sewage backup is category-3 “black water” — it carries bacteria, viruses, and parasites and is a genuine health hazard. It needs sealed containment, negative air pressure, and proper disinfection to make your home healthy again.
Category-3 water carries bacteria, viruses, and parasites, and it soaks into porous materials that cannot simply be wiped down. Proper cleanup means sealing the area under negative air pressure, removing what is contaminated, and disinfecting every affected surface - to a standard that protects your family's health, not just the look of the room.
What Guardian does
- Sealed containment around the affected area to stop cross-contamination

- Safe removal of contaminated water and materials
- Disinfection and antimicrobial treatment of all affected surfaces

- Disposal that follows health and environmental regulations
- Full documentation for your claim
How we put it right
A calm, proven sequence — and we document every step for your claim.
- 1
Containment & negative air
We seal off the affected area with physical containment and set up negative air machines with HEPA filtration, so contaminated air is scrubbed and exhausted instead of drifting through the rest of your home.
- 2
Removal & disposal
With the area under negative pressure, contaminated water and unsalvageable porous materials are removed and disposed of following health and environmental regulations.
- 3
Cleaning & disinfection
Every affected surface is cleaned and treated with antimicrobial disinfectants rated for category-3 contamination.
- 4
Deodorizing
We neutralize odour at the source rather than masking it, so the smell does not creep back days later.
- 5
Drying & clearance
The area is dried under negative air and verified before containment comes down and we restore it to a safe, usable space.
