Damp, mould & MVHR expert in Clervaux
Clervaux and its surrounding villages (Marnach, Hosingen) have a distinctive Ardennes rural building stock. Our diagnoses take account of the shale, the high rainfall and the seasonal use common in the region (second homes, guest houses).
Dominant building stock in Clervaux
Rural and tourist building stock: Ardennes farmhouses in shale, village houses around the abbey, and modern tourist accommodation.
Observed damp pathologies
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.

Why a sworn damp expert in Clervaux?
A "free expertise" is generally performed by a sales rep who will then sell the in-house solution. In Clervaux 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 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.
Damp expert in Vianden
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.
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.
