- Glazing Upgrades: Depending on the client's needs, initial glass might be maintained, or "Slimlite" double glazing can be installed to improve thermal efficiency without altering the window's profile.

| Factor | Description | Effect on Price |
|---|---|---|
| Variety of Panes | Conventional 6-over-6 panes require more information work than 1-over-1. | Moderate |
| Degree of Rot | Substantial sill or box frame replacement increases labor and products. | High |
| Glazing Type | Changing from single glazing to vacuum glass or slim double glazing. | High |
| Availability | Requirements for scaffolding or high-reach platforms. | Moderate |
| Paint Stripping | Total elimination of lead-based paints (needs expert safety equipment). | Moderate |
The Role of Modern Materials in Traditional Restoration
A leading sash window remediation company does not just utilize 19th-century methods; they integrate modern material science to improve the window's performance.

- Epoxy Resins: Advanced bonding representatives that can support old timber and provide a long-term repair that is more powerful than the wood itself.
- Vacuum Glazing: An ultra-thin glazing option (as thin as 6mm) that provides the thermal efficiency of triple glazing while fitting into the initial thin refunds of 18th-century sashes.
