The Professional Installation Process

1. The Technical Survey
Before any production starts, a technical property surveyor will visit the property.

They will likewise keep in mind particular requirements, such as "drip vents" for ventilation or particular hardware surfaces to match existing design.
2. Customized Manufacturing
Sliding sash windows are rarely "off-the-shelf." They are normally bespoke items manufactured to the specific specs of the study. This phase can take anywhere from 4 to 12 weeks depending upon the product and the complexity of the design.
3. Elimination and Preparation
On the day of setup, the installers will secure the interior floors and furnishings. The old windows are carefully gotten rid of to prevent damaging the surrounding brickwork or internal plaster. This is especially delicate in period properties where "box frames" are typically recessed behind the outer leaf of masonry.
4. Fitting and Levelling

5. Sealing and Finishing
Once repaired, the gap between the window and the wall is insulated and sealed with top quality perimeter sealants. Internal "architraves" and external "pointing" (utilizing mortar or silicone) are used to provide a smooth, weather-tight surface.
