A pre-purchase inspection is the most effective way to uncover problems before they become your responsibility. [Get protected today](/en) ### Early detection Spot warning signs before you commit: moisture, cracks, faulty wiring, failing systems. ### Legal protection A professional report provides solid evidence if disputes arise later. ### Risk quantification Every potential issue comes with a repair cost estimate. ### Peace of mind Buy knowing exactly what you're getting. No surprises after signing. ## 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. ## What our clients say 400+ verified Google reviews — Average rating 4.9/5 "Very satisfied with the audit.

No inspection can guarantee the complete absence of hidden defects — some problems are concealed behind walls or underground. But a professional inspection dramatically reduces the risk by identifying visible warning signs and measurable indicators. What if I discover a defect after buying? Act quickly: have the defect documented by an expert, notify the seller by registered letter, and seek legal advice. Luxembourg law protects buyers, but you must act within a reasonable timeframe. Is it worth getting an inspection for a new build? Absolutely. New builds can have construction defects (malfaçons). Catching them before the guarantee period expires means the builder — not you — pays for repairs. ## See what others miss Our architects are trained to find what your eyes can't.
