Rénovation Maison

If you're considering investing in one or more old properties in Boulogne-Billancourt, renovation is a crucial step in realizing your project(s). Located in the western suburbs of Paris, the capital of the Hauts-de-Seine department is full of old buildings with exceptional charm. The noble materials and traditional architecture give its real estate heritage a unique beauty. If you want to contribute to preserving this architectural heritage, don't hesitate to purchase a property for renovation. Whether the house you're buying is to be used as a primary residence, rented out, or sold, its rehabilitation remains worthwhile. Here's a guide to successfully carrying out your project.

Rénovation Maison

Assess the current condition of your house in Boulogne-Billancourt to renovate it better

Not all houses for sale in Boulogne-Billancourt are equal. Therefore, don't make your purchase on a whim. Carefully assessing its current condition is essential to estimate the necessary work and evaluate the profitability of the project.

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

Poorly insulated homes are bad for both your health and your wallet. Therefore, analyzing insulation remains important when you visit the property you're interested in.

If you're making your real estate purchase during the winter season, here are some signs of poor insulation that should alert you :

      • Interior floors and walls are abnormally cold ;

      • You feel drafts near windows and doors ;

      • Some rooms in the house are cooler than others ;

      • The heat emitted by the heating system is not distributed evenly ;

      • The heating bill is very high ;

      • Mold develops indoors due to high humidity ;

      • The roof melts quickly.

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

        • You suffer from heat indoors ;

        • The air conditioning bill is very high ;

        • Mold develops in the basement.

      From this examination, you can determine the necessary insulation work (roof and attic insulation, wall, door, and window insulation, floor insulation).

      Other elements not to be neglected

      You should also focus on the electrical installations. Check if these devices comply with the standards in force in France. Otherwise, they require updates.

      As for plumbing, check the condition of the pipes, plumbing fixtures, and sanitary installations. Detect any potential problems with water pressure, water quality, or leaks.

      Also, evaluate the heating system, especially its performance and compliance. To enjoy good indoor air quality, don't forget to check the effectiveness of the ventilation system.

      Carefully Planning the Renovation of Your Home in Boulogne-Billancourt

      After assessing the condition of the house you covet, you know what needs to be renovated. Now, meticulous planning of the rehabilitation work is necessary.
