Hazardous Substances and Remediation

Whether building moisture, hazardous substances analysis and remediation, the quality of indoor air, or energy rehabilitation is concerned.

Workers at a building renovation

WESSLING is there to assist developers, planners, public authorities, the remediation industry and tradespeople as a trusted advisor for construction and remediation work in existing buildings.

Hazardous building substances, often known as “household toxins” in public discussions, are detrimental to users’ health and can reduce the value of a building. Our experts determine the numerous contaminating effects of hazardous building substances, plan and supervise remediation measures, e.g. for asbestos, wood preservatives and synthetic mineral fibres (SMF).

Our teams know the particularities of remediating PCB-contaminated sealants and other sources. Additionally, the specific treatment of damage by moulds, dry rot, particulate matter or pests is no problem for them either.
