Damp, mould & MVHR expert in Vianden
Vianden, a heritage gem of the Oesling region, has a historic building stock unique in Luxembourg. Our non-destructive survey respects the constraints of the Sites & Monuments authority and offers solutions compatible with heritage conservation requirements.
Dominant building stock in Vianden
A medieval town on the banks of the Our, dominated by its castle: old stone houses from the 17th-19th centuries, a few houses on the hills, and tourist accommodation.
Observed damp pathologies
The enclosed Our valley: reduced sunlight, high ambient humidity and very damp cellars cut into the rock. Medieval houses: widespread rising damp in stone walls without a damp-proof course.

Why a sworn damp expert in Vianden?
A "free expertise" is generally performed by a sales rep who will then sell the in-house solution. In Vianden as anywhere in Luxembourg, the diagnosis we coordinate is paid but independent: the real cause is identified objectively. HUMINUS then carries out the works that fall within its scope (MVHR, ventilation, indoor air quality) and refers you to the right specialist for the rest. The report is admissible by your insurer, building manager or a court.

Damp expert in Clervaux
Ardennes shale farmhouses: very thick but poorly ventilated walls, with damp trapped behind recent stud walls. Tourist properties closed for part of the year: damp recurring and mould frequently appearing when heating is switched back on.
Damp expert in Ettelbruck
At the confluence of the Sûre and Alzette: a high water table and centennial flood risk in the centre. Older houses in the centre combine rising damp with post-flood lateral infiltration, while newer developments near the CHdN hospital suffer from condensation and poorly adjusted MVHR systems.
Damp expert in Wiltz
Highly absorbent Ardennes shale: severe lateral infiltration on façades exposed to driving rain from the north-west. Below-ground cellars cut into the rock: chronic capillary damp and inadequate ventilation.
