Old paint is removed away to expose the condition of the wood. Locations impacted by "damp rot" are sculpted out. Small locations can be repaired using high-performance wood bonding resins, whereas larger areas of structural damage (typically the window sill) may need "splicing"-- where the rotten section is cut out and replaced with a brand-new piece of experienced hardwood.
3. Glass and Glazing

| Expense | Usually 30-50% less expensive than premium wood replacement. | High initial capital outlay. |
| Resilience | Initial slow-grown timber can last another 100 years. | Modern lumber varied; uPVC has a ~ 20-year life-span. |
| Thermal Efficiency | Outstanding with draught-proofing and slim-glazing. | Greatest possible rankings with modern frames. |
| Environmental Impact | Low (uses existing products). | High (production and disposal of old frames). |
