Renovations, heritage and volumes

For your renovation plans in Aarau, federal building register figures are vital. With 467 buildings under heritage protection, it is crucial to contact the municipality early to address permit requirements. The median house volume is 800 m3, which serves as a key indicator for scaling insulation or heating upgrades. Please note that data coverage regarding volume is partial, as only 20 houses were measured according to the SIA 416 standard. We recommend verifying the precise dimensions of your specific property before starting any works to ensure your renovation budget remains accurate and effective for your project.

Planning and assessment

The first step is to inventory your windows. Count your windows by size, whether small openings, standard formats, French doors, or large bay windows. This distinction is crucial for getting a fairer price from contractors.

Also, analyze the condition of your existing frames. If the frame is still in good condition, a simple glass replacement might be enough. If the structure is old, a total removal is recommended.

Use the RenoIndex estimator to estimate the budget needed based on your property's actual configuration to avoid financial surprises.

Regulatory and aesthetic aspects

In Aarau, as everywhere, it is crucial to check local constraints before choosing your new windows.

If your home is in a protected area or if your facades are visible from the public space, the shape, material, and colour of the frames may be subject to strict rules. It is advisable to consult the urban planning department before signing a contract.

Respecting architectural harmony is often mandatory to maintain the historical value of the neighbourhood. A wise choice will allow you to combine energy efficiency with local heritage.

Grants and financial aid

Financial aid, available depending on the current programs, usually targets a comprehensive renovation of the building's thermal envelope. To benefit from support, it is better to combine window replacement with wall or roof insulation work.

Check with the competent authorities in the canton of Aargau for current criteria. Holistic planning can unlock significant funds and increase your long-term investment's profitability.

Optimising the investment

Investing in high-quality windows is a wise decision to increase your property's value. Beyond thermal comfort, high-performance joinery improves sound insulation, a major advantage in urban settings.

To optimize your budget, compare quotes taking into account the materials (PVC, wood, metal) that directly influence price and durability. Remember that installation cost is a significant factor.

By using RenoIndex data, you can compare different options and ensure your investment meets current energy performance standards. Good insulation is the key to sustainably reducing your heating costs.

Frequently asked questions

Can I get a grant for window replacement alone?

Generally, windows alone are rarely subsidised as grants often target a full envelope renovation. It is best to check the active cantonal programs in the canton of Aargau to confirm if exceptions or combinations with other insulation measures are possible for your specific project.

How can I get a cost estimate in Aarau?

For a quick and free estimate, you can use the RenoIndex calculator. It allows you to calculate a price range based on the number and size of your windows, providing a solid foundation for preparing your quote requests from local contractors.

Do I need to declare the window replacement to the authorities?

Yes, in certain cases, especially if you are in a protected area or if your facade is visible from the public space. It is essential to check local rules with your municipality's urban planning department before starting work that could alter the building's exterior appearance.

Which materials should I choose for my new windows?

The choice depends on your budget, desired aesthetics, and maintenance preferences. PVC is often the most economical, wood offers a warm aesthetic, and metal ensures great durability. Evaluate your thermal and acoustic insulation needs before making your final decision.
