Preparing your window project
Before starting, it is essential to identify your needs precisely. Count your windows by size, distinguishing between small openings, standard formats, French doors, and large bays. This step is crucial for obtaining a consistent quote.
Also, consider evaluating the condition of existing frames and current thermal performance.
For a quick assessment of costs based on local market prices in Lenzburg, we recommend using the RenoIndex simulator, which will provide an estimated price range in Swiss francs to guide your initial financial decisions.
Energy performance and grants
It is therefore wise to combine your glazing work with facade or roof insulation. To plan your overall investment without surprises, use our RenoIndex tool to get reliable price ranges for your windows before checking official cantonal programmes.
Aesthetic constraints and regulations
Before placing an order, check the current regulations in your neighbourhood. Complying with these rules ensures the success of your renovation project.
For a realistic cost estimate incorporating these variables, do not hesitate to use the RenoIndex simulator to learn about the prices charged in your region.
Choosing the right material
The choice of frame material depends on your expectations regarding maintenance, durability, and budget. PVC is often favoured for its excellent price-quality ratio and efficient thermal insulation.
Wood offers natural character and increased durability, while aluminium allows for very thin profiles and exceptional weather resistance. Each material influences the final price of your renovation in Lenzburg.
To compare these options financially, use the RenoIndex simulator, which will provide an estimated price range, helping you decide between performance, aesthetics, and available budget.

Frequently asked questions
How long does it take to get a quote?
Getting an immediate price range is possible by using our RenoIndex simulator. For a detailed quote, it will depend on the availability of local companies in Lenzburg and the complexity of your specific project, but generally expect a few days to two weeks to receive precise offers.
Do I need a permit to change my windows?
In most cases, a simple replacement with identical windows does not require a permit. However, if your building is listed or located in a protected area, you must consult the urban planning department in Lenzburg before starting any facade modification work.
Can I install windows myself?
Although DIY is possible, window replacement requires technical expertise to ensure sealing, insulation, and safety. Improper installation can negate expected energy gains. It is strongly advised to hire qualified professionals to ensure optimal performance and the durability of your new windows.
Which material is the most durable?
Wood-aluminium is often considered the most durable. Wood provides interior insulation, while the exterior aluminium protects the structure against harsh weather. This is an excellent long-term investment that requires very little maintenance while offering superior thermal protection.
