Damage to the building, such as damp walls and their consequences, can become a dispute or even a legal case. For example, if the damage threatens to reduce the value of the building fabric, or if mold develops, causing health problems. In such cases, it is good to be able to call on the services of an independent construction damage expert who can provide a professional expert opinion. As building experts and building surveyors, as well as building biologists and energy consultants with many years of experience, we prepare expert and professional building reports. In addition to appraisals and expert reports, we do construction and energy consultations.

Our construction experts analyze the cause of your building damage and determine the damage potential. The construction expertise can help to clarify important questions, such as: Is the damage due to structural defects or incorrect behavior on the part of the building's occupants? Along with the clarification of these and similar questions, we prepare private expert opinions (party expert opinions) or construction expert opinions for insurance companies and courts.
