1. Assessment and Removal

In many restorations, this is an opportunity to set up "slimline" double-glazed systems, which fit within the original sash profile.
4. Draught-Proofing Integration
Among the most significant upgrades throughout remodelling is the setup of a draught-proof system. Brush strips or stack carriers are quietly machined into the staff beads, parting beads, and meeting rails. This removes rattling and considerably reduces thermal loss.
5. Re-balancing and Re-stringing
The sashes are weighed, and the internal weights are gotten used to match perfectly. New sash cables are installed, making sure the window runs with "finger-touch" ease.
6. Painting and Finishing
To guarantee longevity, the timber is primed, undercoated, and ended up with top quality micro-porous paint. This type of paint allows the wood to "breathe," preventing moisture from ending up being trapped under the surface and causing future rot.
