- Sill Replacement: The windowsill is typically the most broken part. Experts typically replace these with resilient hardwoods or Accoya ® wood to avoid future rot.
- Draught Proofing: This is perhaps the most transformative step. Discreet grooves are machined into the sashes or the personnel beads to house brush strips, creating an airtight seal while permitting smooth motion.
- Glazing Upgrades: Depending on the customer's needs, original glass may be retained, or “Slimlite” double glazing can be set up to improve thermal efficiency without modifying the window's profile.

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