2. Wood Restoration

Old paint is removed away to reveal the condition of the wood. Areas affected by "damp rot" are carved out. Small locations can be fixed utilizing high-performance wood bonding resins, whereas larger sections of structural damage (frequently the window sill) may need "splicing"-- where the rotten area is cut out and changed with a brand-new piece of seasoned hardwood.

3. Glass and Glazing

In numerous renovations, 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 during restoration is the installation of a draught-proof system. Brush strips or stack providers are discreetly machined into the staff beads, parting beads, and meeting rails. This removes rattling and significantly minimizes thermal loss.

5. Re-balancing and Re-stringing

The sashes are weighed, and the internal weights are adapted to match perfectly. New sash cords are set up, ensuring the window runs with "finger-touch" ease.

6. Painting and Finishing

To ensure durability, the timber is primed, undercoated, and ended up with top quality micro-porous paint. This type of paint enables the wood to "breathe," preventing wetness from becoming caught under the surface area and triggering future rot.
