What is extreme and hazardous cleaning?

Extreme and hazardous cleaning is designed for properties or premises where the condition, level of contamination or known risks require a more carefully planned approach than a routine cleaning service.

Situations can vary considerably, from severely neglected or heavily soiled properties to environments where biological contamination, sharps or other potential hazards may be present.

We assess each enquiry individually before agreeing the appropriate scope of work.

WHAT’S INCLUDED

Specialist Cleaning Built Around the Situation

Depending on the property, condition and hazards identified, the service may include:

Assessment of affected areas
Cleaning of heavily soiled surfaces
Kitchens, bathrooms and living areas
Floors and accessible surfaces
Cleaning of neglected or vacant properties
Attention to identified contamination
Appropriate disinfection where required
Identification of sharps or biological hazards
Agreed removal of affected materials
Reporting of additional specialist requirements

The exact service will be determined following an assessment of the property and circumstances.

If sharps, bodily fluids, unknown substances or other hazards are present, please tell us before entering or disturbing the affected area.

Every Situation Is Assessed Individually

Extreme cleaning situations are rarely identical, so we do not use a standard package or instant-price approach.

We will ask about the property, its current condition, known hazards, approximate affected areas, access arrangements and urgency before determining the appropriate next step.

Where there may be potentially hazardous contamination, avoid disturbing or attempting to clean the affected materials unnecessarily.

Envirowise FAQs

What situations may require extreme or hazardous cleaning?

This service may be suitable where a property is severely neglected, heavily contaminated or contains potential hazards that make routine cleaning inappropriate.

Can you clean very heavily soiled properties?

Yes. We can assess properties in poor or heavily soiled condition and determine the level of specialist cleaning required.

What if sharps, bodily fluids or unknown substances are present?

Tell us when making your enquiry and avoid disturbing them unnecessarily. The presence of additional hazards can affect how the service needs to be planned.

Do you provide an instant price for extreme cleaning?

No. Because conditions can vary considerably, we first assess the property and requirements before confirming the scope and quotation.
