Frequently Asked Questions
Is sewage backup dangerous to my health?
Yes, sewage contains harmful bacteria, viruses, and pathogens. Exposure can lead to serious illness. Professional cleaning and sanitisation are essential to ensure the environment is safe for habitation.
How quickly should sewage be cleaned up?
Sewage restoration should begin immediately. Damage to structural elements and soft furnishings worsens every hour, and biohazard risks increase as bacteria multiply in stagnant water.
Does home insurance cover sewage cleaning costs?
Most insurance policies cover sewage damage if it's caused by a sudden event. We are insurance experts and work directly with your provider to manage the claim efficiently.
What can I do to prevent future sewage backups?
Regular maintenance of your drains, avoiding the disposal of oil or grease down the sink, and installing backwater valves can significantly reduce the risk of future sewage ingress.
Can I clean up a sewage spill myself?
We strongly advise against it. Sewage is a biohazard that requires professional-grade protective equipment and industrial disinfectants to ensure complete sanitisation and safety.
