Old paint is removed away to expose the condition of the wood. Locations impacted by "damp rot" are sculpted out. Little areas can be repaired utilizing high-performance wood bonding resins, whereas larger sections of structural damage (typically the window sill) might need "splicing"-- where the rotten section is eliminated and replaced with a brand-new piece of skilled hardwood.
3. Glass and Glazing
Initial cylinder or crown glass has a special "wavy" look that many house owners wish to keep. If the glass is broken, it is changed with period-accurate glass or modern shatterproof glass. In numerous restorations, this is a chance to install "slimline" double-glazed systems, which fit within the initial sash profile.
4. Draught-Proofing Integration
One of the most substantial upgrades throughout restoration is the installation of a draught-proof system. Brush strips or stack carriers are quietly machined into the personnel beads, parting beads, and conference rails. This removes rattling and substantially minimizes thermal loss.
5. Re-balancing and Re-stringing
The sashes are weighed, and the internal weights are changed to match completely. New sash cables are set up, guaranteeing the window operates with "finger-touch" ease.
6. Painting and Finishing
To ensure durability, the wood is primed, undercoated, and finished with high-quality micro-porous paint. This type of paint permits the wood to "breathe," preventing wetness from ending up being caught under the surface area and causing future rot.

| Cost | Normally 30-50% less expensive than top quality timber replacement. | High initial capital expense. |
| Durability | Original slow-grown timber can last another 100 years. | Modern wood varied; uPVC has a ~ 20-year life-span. |
| Thermal Efficiency | Excellent with draught-proofing and slim-glazing. | Highest possible ratings with modern frames. |
| Ecological Impact | Low (uses existing products). | High (production and disposal of old frames). |
