What counts as a hidden defect?
A hidden defect (vice caché) is a serious problem that isn't visible during a normal viewing and that makes the property unfit for its intended use or significantly reduces its value. Think structural issues behind the plaster, water infiltration behind a fresh coat of paint, or dangerous electrical installations hidden behind walls.
Under Luxembourg law, sellers are liable for hidden defects — even if they didn't know about them. But pursuing a legal claim after purchase is expensive, stressful, and uncertain. Prevention is always better than cure.
Most common hidden defects in Luxembourg
Our architects regularly encounter the same issues: water infiltration and rising damp (especially in older buildings), structural cracks from ground movement, non-compliant electrical installations, failing roofs hidden by cosmetic repairs, and inadequate ventilation causing mould.
Many properties in Luxembourg were built before modern standards. A professional inspection can tell you whether these potential issues have been properly addressed — or if they're ticking time bombs.
Prevention costs less than the cure
An inspection costs a few hundred euros. A roof replacement costs €30,000+. Structural repairs can run into six figures. The inspection fee is negligible compared to the financial risk of buying blind.
And if the inspection shows everything is sound? Then you've just bought yourself certainty — and that's priceless when making the biggest financial decision of your life.
