Damp, mould & MVHR expert in Mersch
Mersch, where the Alzette, Eisch and Mamer rivers meet, has a recurring damp substrate. Our diagnoses distinguish lateral infiltration, rising damp and salt-related hygroscopic damp — three pathologies that are easily confused visually in the valley's cellars.
Dominant building stock in Mersch
The geographical heart of the country: old terraced houses along the Alzette, stone farmhouses in Pettingen and Reckange, and developments from the 1990s-2010s in Beringen and Rollingen.
Observed damp pathologies
The Alzette valley: a high water table, chronically damp cellars and frequent lateral infiltration in stone buildings. Newer houses mainly suffer from condensation and thermal bridges at north-facing corners.

Why a sworn damp expert in Mersch?
A "free expertise" is generally performed by a sales rep who will then sell the in-house solution. In Mersch 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 Strassen
The 1970s-80s villas show thermal-bridge problems and infiltration through flat roofs. The newer developments suffer from clogged balanced MVHR systems (construction dust).
Damp expert in Mamer
The old farmhouses of Holzem and the centre combine rising damp with damp below-ground cellars. The new Capellen developments show recurring condensation linked to balanced MVHR systems undersized for the living volume.
Damp expert in Luxembourg-Ville
The vaulted cellars of the historic centre suffer from chronic rising damp. The newer Kirchberg developments, by contrast, see condensation problems caused by an overly airtight envelope and poorly adjusted MVHR systems.
