Damp, mould & MVHR expert in Wiltz
Wiltz, capital of the Luxembourg Ardennes, has a building stock in local stone (shale, sandstone) that is particularly sensitive to driving rain and rising damp. Our heritage expertise distinguishes structural pathologies from simple maintenance defects.
Dominant building stock in Wiltz
A tiered Ardennes town: shale and stone houses in the Haute-Ville, former tanneries converted in the Basse-Ville, and Goodyear workers' housing from the 1960s.
Observed damp pathologies
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.

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