The Professional Installation Process

1. The Technical Survey

Before any production starts, a technical surveyor will go to the property. They take accurate measurements (to the millimeter) and assess the structural stability of the existing apertures. They will also note particular requirements, such as “trickle vents” for ventilation or specific hardware finishes to match existing decor.

2. Customized Manufacturing

Sliding sash windows are rarely “off-the-shelf.” They are typically bespoke items produced to the exact specifications of the survey. This phase can take anywhere from 4 to 12 weeks depending on the material and the complexity of the style.
