Casement windows for residential and historic buildings
For owners’ associations, owners and building managers we make and install wooden casement windows. We follow the original architecture and handle the replacement from survey through to finishing work.
- We work with heritage authorities
- 25,000+ windows made
A new window should blend into the building, not draw attention to itself
Casement windows have outer and inner sashes separated by a cavity. Their depth, their division and their profiles are part of the architecture of traditional town houses. When replacing them, both the whole and the detail matter: new windows should follow the appearance of the facade and suit the way the building is used. We prepare solutions for residential buildings, hotels, schools and listed properties.
We will help you find your way around grants
Replacing historic windows is a big decision for a residential building. Add heritage conservation requirements and the question of financial support, and it can be hard to know where to start. We have completed projects for which a grant was successfully obtained.
We will go through the options for your building with you, prepare the technical documentation for the windows and, where needed, take part in discussions with the heritage authorities. You will know exactly what needs to happen next.
Listed buildings
The result depends on details that need to be settled early
With buildings in conservation areas, the requirements for the appearance of the new windows need to be clarified early. The division, the profiles, the colours and the way they open all matter. We have experience of working with heritage authorities. We will go through the documentation with you and propose the next steps, so that the execution is clear before manufacture begins.
- The original windows and the documentation available
- Requirements for appearance and construction
- An approved specification before manufacture
Are you also arranging funding for the restoration?

From the first conversation to finished windows
On a larger building, how the windows are made matters just as much as how the replacement is organised. So we agree the scope and the sequence of the work in advance.
-
01 / Pricing
We go through your plans
Send us the address, the number of windows, approximate dimensions and photographs. We will confirm the scope of supply and what we need for a quotation.
-
02 / Survey
We finalise the specification
We survey the openings and go through the technical details. We agree the material, the appearance, the fittings and the conditions for installation.
-
03 / Production
We make them in Děčín
Our joiners make the windows to the approved brief. The surface finish and final assembly are part of production.
-
04 / Installation
We replace and hand over
On the agreed date we carry out the replacement and the finishing work agreed. At handover we explain how to operate and maintain them.

What you ask us most often
Ideally before you order manufacture or start any work. The sooner we look at the project, the better we can coordinate the technical solution, the documentation and the deadlines.
Yes. We have worked with conservation authorities for a long time and know which documents they need when historic windows and doors are restored. As agreed, we can act as an intermediary or take over the communication entirely.
Approval of the application depends on the funding provider, so it cannot be guaranteed in advance. But we will help you prepare the technical documents, put the paperwork together and make sure everything is submitted correctly and on time.
Send us the address of the building, photos and a short description of the planned work. We will look at your plans and tell you what is worth looking into further.
Replacement usually takes two days. The exact duration of the replacement depends on the number and construction of the windows, access to the apartment and the extent of finishing work. We confirm the schedule before installation begins.
For an indicative price we only need the number and dimensions of the windows, the type of building, and whether it is a listed building. The better the documents we receive, the more accurately we can assess your enquiry.
We use quality solid timber and laminated sections, which guarantee a long service life and dimensional stability.
Wooden windows and doors only need regular cleaning and, from time to time, a fresh coat of finish. Detailed instructions are supplied with every contract.
The choice of hinges depends on the type of window and on the requirements of heritage conservation. We will gladly recommend a suitable solution on site.
The whole process of replacing the windows in a single apartment usually takes two days. The maximum number of box windows replaced in one day is 7. All the work is normally carried out from the interior.
