When is a property considered unsanitary?

A property becomes unsanitary when the level of deterioration, clutter, dirt, or contamination puts hygiene, health, or safety at risk. In these situations, basic housekeeping is no longer enough: a specialist intervention is needed.

  • Stained walls, greasy surfaces, or heavily soiled areas
  • Presence of urine, faeces, or persistent bad smells
  • Rooms filled with rubbish, furniture, or accumulated waste
  • Persistent odours and poor ventilation
  • Visible mould and damp indoor conditions
  • Pests: cockroaches, fleas, bed bugs, mice, pigeons
  • Difficult movement through the property or specific rooms
  • Health risks for occupants, neighbours, or professionals

FAQ – Extreme cleaning & unsanitary housing

Do you work on extreme properties such as Diogenes syndrome cases or squats?

Yes. We work on heavily degraded properties, Diogenes syndrome situations, squats, and homes that have become unsanitary.

What does a deep cleaning service include?

It generally includes clearance, cleaning of surfaces, disinfection, odour treatment, pest control, and full sanitising.

What are the health risks of an unsanitary property?

The risks include bacteria, mould, odours, pests, property deterioration, and negative effects on health and safety.

The price depends on the surface area, the volume of waste, the level of unsanitary conditions, the risks involved, the products required, and the time needed.
