2. Custom-made Manufacturing
Sliding sash windows are hardly ever "off-the-shelf." They are generally custom products manufactured to the specific requirements of the study. This stage can take anywhere from 4 to 12 weeks depending on the product and the complexity of the style.

4. Fitting and Levelling
The new frame is positioned and levelled using laser tools. For sliding sash windows, absolute vertical and horizontal precision is non-negotiable. If the frame is skewed, the weights or balances will not function correctly.
5. Sealing and Finishing
As soon as fixed, the space in between the window and the wall is insulated and sealed with top quality boundary sealants. Internal "architraves" and external "pointing" (using mortar or silicone) are applied to offer a smooth, weather-tight surface.

Maintenance Tips for Longevity
Even the best-installed windows require care. Installers normally advise the following:
