Practical guidance
Which service should you choose for your property?
Use this page to identify the right starting point based on suspicious materials, contamination signs and the real condition of the site.
Start with the right service
When a building shows more than one issue at the same time, it is not always obvious whether you should begin with sampling, decontamination, mould remediation, vermiculite removal or selective demolition. The cards below help point you to the most useful next step.
Suspicious material or hazardous dust
If the building contains suspicious materials or dust that may be hazardous, decontamination is often the right first service to frame the intervention.

When the material is still uncertain, sampling is often the best starting point to confirm the presence or absence of asbestos or other contaminants.

If vermiculite is present and must be removed before work continues, start with the dedicated vermiculite removal service.

If the priority is contamination caused by moisture, mould remediation may be the best first intervention before further work.

If materials need to be taken out cleanly before the next phase, selective demolition is usually the right follow-up service.

What is the best first step if I am not sure what the material is?
When the material is still uncertain, sampling is often the best starting point. It helps confirm the real condition of the site and avoids moving in the wrong direction.
When should I choose decontamination instead of selective demolition?
Decontamination is generally the right fit when the priority is hazardous or contaminated materials. Selective demolition is the better fit when sections of the building must be opened or removed in a controlled way.
Can sampling help before decontamination work starts?
Yes. Sampling is often the best way to confirm the presence or absence of asbestos or other contaminants before decontamination or demolition begins.
