Renovation: Changing windows in La Chaux-de-Fonds

3 °C and about 100 frost days per year. These conditions require high-performance thermal insulation to limit heat loss.

Replacing windows is particularly opportune when the current joinery shows signs of wear, such as internal condensation, persistent drafts, or single glazing.

With 3,824 Kj/year of heating degree days, renovation allows you to significantly reduce your energy requirements and improve the quality of life inside your home.

The choice of materials is decisive for the durability of your investment. Wood offers a warm aesthetic and excellent insulation, while PVC is recognized for its ease of maintenance.

Aluminum, meanwhile, appeals for its robustness and finesse, often favored in modern architectures.

Beyond the material, energy performance depends on the type of glazing. It is advisable to count your windows by size, whether small openings, standard models, French windows, or large bays, to establish a fair quote.

Finally, options such as integrated blinds, the type of opening, or acoustic treatments play a crucial role in the daily comfort of your high-altitude home.

For buildings constructed before 1990, it is imperative to check for the potential presence of pollutants, particularly asbestos in old sealants or joints, before any dismantling intervention.

Buildings in this area may also have complex configurations regarding window embrasures. Special attention must be paid to the insulation of the rebates and the connection to the existing envelope to avoid thermal bridges.

Prior expertise makes it possible to ensure that the new joinery integrates without compromising overall airtightness, an essential factor in a harsh climate.

It is highly recommended to contact the competent authorities before starting your renovation project. Generally, any change affecting the exterior appearance must be submitted for verification.

If solar installations are planned on your new windows or facades, inquire about simplified notification procedures, while remaining vigilant regarding the heritage classification of your building.

It is imperative to carry out the subsidy application procedures BEFORE starting the work.

Tax-wise, the canton of Neuchâtel allows for the deduction of investments aimed at saving energy. If the actual costs cannot be fully deducted in the year of invoicing, they can be carried forward to the two following tax years.

Note that in case of carry-forward, the flat-rate deduction cannot be chosen for the concerned building during this period.

Finally, know that the municipal energy fund may also support certain renovation measures; always check the current eligibility of your project with the municipal services.

The planning of a construction site in La Chaux-de-Fonds must take into account the harsh winter conditions. Window installation is ideally carried out during milder seasons, although it is technically feasible all year round.

The steps always begin with precise measurement, followed by the ordering of joinery.

Once the elements are delivered, the site progresses with the dismantling of old structures, the installation of new frames, and then sealing finishes. It is crucial to organize the site to minimize the duration of the dwelling's exposure to the elements.

Good coordination with the chosen company ensures smooth execution and limits inconvenience for occupants.

Avoid the common mistake of neglecting global sealing after installation, as a high-performance window in non-airtight masonry loses its efficiency. Do not sign any contract without checking if aid is available for your project.

Before asking for quotes, ensure you have a precise list of all your openings. Also, check if your building is subject to heritage protection rules or color constraints.

Finally, require that the quote includes details on installation, joint treatment, and proper disposal of old elements.
