Asbestos is a material consideration in property transactions worldwide. For buyers, undisclosed asbestos can mean significant unexpected costs. For sellers, failure to disclose known asbestos can result in legal liability. In many jurisdictions, pre-sale asbestos surveys are legally mandatory, and results must be shared with buyers before completion. Our network includes certified surveyors who provide transaction-ready reports meeting legal requirements, as well as contractors who can carry out pre-sale remediation to remove barriers to completion.

This varies by jurisdiction. In France, the DAPP (Diagnostic Amiante Parties Privatives) is mandatory for all residential sales of buildings built before July 1997. In Belgium (Flanders), an asbestos attestation has been required since 2022. In the UK and US, there is no mandatory pre-sale survey for residential properties, though commercial transactions typically include one.
The presence of managed asbestos in good condition typically has minimal impact on value. However, extensive ACMs requiring removal can reduce value by the estimated remediation cost. Properties with clear asbestos reports (especially negative results) can actually sell more easily as they remove buyer uncertainty.
Most residential surveys can be conducted within 1-2 weeks of instruction. The property inspection itself takes a few hours. Laboratory results typically return within 3-5 working days. Urgent turnarounds are available from many providers for time-sensitive transactions.
If the seller knew about and failed to disclose asbestos, buyers may have legal recourse depending on jurisdiction. If the asbestos was not previously known, the buyer assumes management responsibility. A management survey should be commissioned to assess condition and determine whether action is needed.
Not necessarily. Well-managed ACMs in good condition can remain in place with proper disclosure. However, if materials are damaged, if you're selling in a market where buyers expect removal, or if the property requires renovation, pre-sale removal can facilitate the transaction and avoid price reductions.
