Company specialised in dendrochronology.

Company specialised in dendrochronology applied to archaeology, architecture and more widely to the heritage of wood.
The purchasing of a 15th century building is no mean achievement, and this action often stems from an enthusiasm for old stone buildings. But we too frequently ignore the wood preserved in the roofing frameworks, ceilings and walls, half-timbered walls and old woodwork, and who is able to vouch as to the origin and the main steps in the construction of your castle or manor house?

The appraisals prepared by Dendrotech are also guided by this shared enthusiasm and combine the accuracy of the dendrochronological dating with the enhancement of your property.

Our know-how and our experience makes it possible for you not only to understand the history of your building, but also, during restoration works, or unfortunately sometimes following fires, thefts, etc. to certify the authenticity and the value of your heritage.
