Damp, mould & MVHR expert in Bertrange
Bertrange combines old rural building stock with upmarket recent residential development. We distinguish the structural pathologies of the old farmhouses from the MVHR malfunctions found in Helfent's new developments.
Dominant building stock in Bertrange
A mix of former farmhouses along the Rue Principale, housing developments from the 1980s-90s, and the Helfent business district (upmarket new developments).
Observed damp pathologies
Former farmhouses: classic rising damp. Helfent and Bourmicht: a strong recurrence of condensation in new developments with poorly adjusted balanced MVHR systems.

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