Frequently Asked Questions

How quickly can you get to my property?
As this is a priority emergency service, we aim to be with you as quickly as possible, often within just a few hours of your call, day or night.
Is sewage in my house dangerous?
Yes. Sewage (blackwater) contains harmful bacteria, viruses, and pathogens. It is a serious health hazard and should only be handled by trained professionals with the correct personal protective equipment (PPE).
Will my home insurance cover the cost of a drain flood?
Most buildings and contents insurance policies offer cover for “escape of water,” but you should check your specific policy. We can provide a full, detailed report for your insurance company to help with your claim.
What causes a drain to flood so severely?
It’s usually caused by a major blockage in your private drain or a problem in the main public sewer. Common culprits include large build-ups of wet wipes, collapsed pipes, or severe tree root ingress.
Do you just fix the drain or do you clean up the mess?
We provide a complete service. Our job isn’t finished until we’ve unblocked the drain, removed all the wastewater, and thoroughly cleaned and disinfected the affected area, making it safe for you again.
