Moisture experts

Professional moisture analysis

We make moisture measurements on parts of the building, such as basements, floors and walls of all materials. Our moisture experts analyze the condition of the building fabric in your building, determine the cause of moisture and provide recommendations and a cost estimate regarding effective countermeasures.

In addition to the moisture expertise, we offer electrophysical dehumidification of building parts with the DRYMAT® system, which is recognized by building science. However, this method is not suitable for acute water damage. Contact us without obligation.

Moisture measurements can be made both for early detection of problems and for specific reasons. Typical occasions are visible traces of moisture such as stains or mold; before, during or after construction work; before the purchase or sale of a property; for the assertion of insurance claims as well as after water damage.
