Damp, mould & MVHR expert in Käerjeng
Käerjeng (Bascharage, Clemency, Hautcharage) brings together several former rural villages. Old stone buildings sit alongside recent insulation work that, paradoxically, has created new damp problems.
Dominant building stock in Käerjeng
Rural and residential building stock: former Lorraine-style farmhouses, houses from the 1980s-2010s, and some new developments towards Bascharage.
Observed damp pathologies
Below-ground cellars in the old farmhouses are often damp, and condensation has recently begun appearing in externally insulated houses whose MVHR systems weren't upgraded to match.

Why a sworn damp expert in Käerjeng?
A "free expertise" is generally performed by a sales rep who will then sell the in-house solution. In Käerjeng 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 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 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 Bertrange
Former farmhouses: classic rising damp. Helfent and Bourmicht: a strong recurrence of condensation in new developments with poorly adjusted balanced MVHR systems.
