The Step-by-Step Renovation Process

2. Timber Restoration
Old paint is removed away to expose the condition of the wood. Areas affected by “wet rot” are carved out. Small locations can be fixed using high-performance wood bonding resins, whereas larger sections of structural damage (frequently the window sill) may need “splicing”— where the rotten section is cut out and changed with a brand-new piece of seasoned wood.
3. Glass and Glazing
Original cylinder or crown glass has a special “wavy” look that numerous house owners wish to keep. If the glass is broken, it is replaced with period-accurate glass or contemporary shatterproof glass. In many restorations, this is a chance to set up “slimline” double-glazed units, which fit within the original sash profile.
4. Draught-Proofing Integration
Among the most significant upgrades during renovation is the setup of a draught-proof system. Brush strips or pile carriers are discreetly machined into the personnel beads, parting beads, and conference rails. This removes rattling and substantially decreases 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 make sure durability, the lumber is primed, undercoated, and finished with high-quality micro-porous paint. This kind of paint allows the wood to “breathe,” preventing wetness from becoming trapped under the surface area and causing future rot.
