3. Glass and Glazing

4. Draught-Proofing Integration
One of the most considerable upgrades during restoration is the setup of a draught-proof system. Brush strips or pile carriers are inconspicuously machined into the personnel beads, parting beads, and meeting rails. This gets rid of rattling and substantially lowers thermal loss.
5. Re-balancing and Re-stringing
The sashes are weighed, and the internal weights are adjusted to match perfectly. New sash cables are set up, making sure the window runs with "finger-touch" ease.
6. Painting and Finishing
To ensure longevity, the timber is primed, undercoated, and completed with premium micro-porous paint. This kind of paint allows the wood to "breathe," preventing wetness from ending up being trapped under the surface area and triggering future rot.
