Inspect the structure

Before buying an old house in the capital of the Hauts-de-Seine department, take the time to meticulously inspect its structure. You should carefully examine the walls, foundations, floors, frames, and beams. For this, don't hesitate to hire a professional in the field. They can identify any signs of deterioration, cracks, or structural problems requiring reinforcement or repair.

During this inspection, consider the age of the building. Obviously, older houses require special attention regarding degraded materials and obsolete systems.

Analyse the insulation

– certaines pièces de la maison sont plus fraîches que d’autres ;

– la chaleur émise par le chauffage ne se répartit pas de façon uniforme ;

– la facture de chauffage est très élevée ;

– des moisissures se développent à l’intérieur, à cause d’un taux d’humidité élevé ;

– la toiture dégèle rapidement.

If the purchase takes place in summer, here are some symptoms of a poorly insulated house :

– vous souffrez de la chaleur à l’intérieur ;

– la facture de climatisation est très élevée ;

– des moisissures se développent au sous-sol.

From this assessment, you can determine the necessary insulation work (roof and attic insulation, wall insulation, door and window insulation, floor insulation). Also, evaluate the heating system, especially its performance and compliance, to ensure good indoor air quality.
