Old paint is removed away to reveal the condition of the wood. Locations affected by “damp rot” are carved out. Small areas can be fixed utilizing high-performance wood bonding resins, whereas bigger sections of structural damage (often the window sill) might require “splicing”— where the rotten area is eliminated and changed with a brand-new piece of experienced hardwood.
3. Glass and Glazing
Initial cylinder or crown glass has an unique “wavy” look that many property owners want to keep. If the glass is broken, it is replaced with period-accurate glass or contemporary security glass.

4. Draught-Proofing Integration
Among the most significant upgrades during renovation is the setup of a draught-proof system. Brush strips or pile providers are inconspicuously machined into the personnel beads, parting beads, and conference rails. This eliminates rattling and substantially minimizes thermal loss.
5. Re-balancing and Re-stringing
The sashes are weighed, and the internal weights are changed to match perfectly. New sash cables are set up, ensuring the window runs with “finger-touch” ease.
6. Painting and Finishing
To guarantee longevity, the timber is primed, undercoated, and finished with high-quality micro-porous paint. This kind of paint enables the wood to “breathe,” avoiding wetness from ending up being caught under the surface and causing future rot.
