2. Lumber Restoration
Old paint is stripped away to expose the condition of the wood. Areas affected by "wet rot" are sculpted out. Little locations can be repaired utilizing high-performance wood bonding resins, whereas larger sections of structural damage (often the window sill) might require "splicing"-- where the rotten area is eliminated and replaced with a new piece of experienced wood.
3. Glass and Glazing
Initial cylinder or crown glass has a distinct "wavy" look that many homeowners want to keep. If the glass is broken, it is changed with period-accurate glass or modern-day shatterproof glass. In numerous restorations, this is a chance to set up "slimline" double-glazed units, which fit within the initial sash profile.
4. Draught-Proofing Integration
One of the most considerable upgrades during remodelling is the setup of a draught-proof system. Brush strips or pile providers are inconspicuously machined into the staff beads, parting beads, and conference rails. This eliminates rattling and substantially lowers thermal loss.
5. Re-balancing and Re-stringing
The sashes are weighed, and the internal weights are adapted to match completely. New sash cables are installed, 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 kind of paint allows the wood to "breathe," preventing moisture from ending up being trapped under the surface and causing future rot.

| Expense | Usually 30-50% more affordable than high-quality timber replacement. | High preliminary capital outlay. |
| Resilience | Original slow-grown timber can last another 100 years. | Modern wood varied; uPVC has a ~ 20-year lifespan. |
| Thermal Efficiency | Outstanding with draught-proofing and slim-glazing. | Highest possible rankings with modern-day frames. |
| Environmental Impact | Low (uses existing materials). | High (production and disposal of old frames). |
