Damp, mould & MVHR expert in Differdange
Differdange and its former mining settlements (Lasauvage, Oberkorn) have a very distinctive stone-and-rubble building stock. Our expertise clearly distinguishes capillary rise, lateral infiltration and salt-related hygroscopic damp — three pathologies that are easily confused visually.
Dominant building stock in Differdange
Mining and steel-making building stock: workers' estates in Oberkorn and Niederkorn, individual houses from the 1970s-80s, and newer housing developments on the outskirts.
Observed damp pathologies
The stone houses of Lasauvage and the workers' estates of Oberkorn commonly combine rising damp with lateral infiltration due to poorly sealed rubble-stone foundations.

Why a sworn damp expert in Differdange?
A "free expertise" is generally performed by a sales rep who will then sell the in-house solution. In Differdange 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 Sanem
The old stone farmhouses of Sanem and Soleuvre combine thick, poorly ventilated walls with damp below-ground cellars. The 1980s houses mainly suffer from thermal bridges and condensation on replaced PVC windows.
Damp expert in Pétange
A high concentration of damp cellars in Rodange (high water table, former mining galleries). Cross-border renovations often hide untreated rising damp behind new stud walls.
Damp expert in Esch-sur-Alzette
In Esch's old workers' houses, rising damp is severe: no damp-proof course, porous bricks, below-ground floors. In Belval, the dominant issue is faulty balanced MVHR systems, with early clogging caused by persistent construction dust.
