Small areas can be fixed utilizing high-performance wood bonding resins, whereas larger areas of structural damage (typically the window sill) may need "splicing"-- where the rotten area is cut out and changed with a new piece of seasoned hardwood.

| Toughness | Original slow-grown wood can last another 100 years. | Modern timber differed; uPVC has a ~ 20-year life expectancy. |
| Thermal Efficiency | Excellent with draught-proofing and slim-glazing. | Highest possible scores with modern frames. |
| Ecological Impact | Low (utilizes existing products). | High (production and disposal of old frames). |
