Damp, mould & MVHR expert in Walferdange
Walferdange, in the Alzette valley just north of the capital, has a naturally damp substrate. Our diagnosis distinguishes 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 Walferdange
A residential commune in the Alzette valley: villas from the 1960s-80s, former period townhouses around the old castle (University), and new developments along the Route de Diekirch.
Observed damp pathologies
The enclosed Alzette valley: a high water table and chronically damp cellars in Helmsange and Bereldange. The 1970s villas also show thermal bridges and flat-roof infiltration, typical of buildings from that era.

Why a sworn damp expert in Walferdange?
A "free expertise" is generally performed by a sales rep who will then sell the in-house solution. In Walferdange 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 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.
Damp expert in Mersch
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.
Damp expert in Hesperange
Howald has a concentration of poorly insulated 1960s-80s flats where condensation causes serious damage in north-facing bedrooms. Alzingen and Fentange are seeing mould appear in cellars converted into living space without prior waterproofing.
