Small areas can be fixed using high-performance wood bonding resins, whereas larger areas of structural damage (often the window sill) may require "splicing"-- where the rotten section is cut out and changed with a new piece of seasoned hardwood.
3. Glass and Glazing

| Cost | Typically 30-50% more affordable than premium lumber replacement. | High initial capital investment. |
| Resilience | Original slow-grown lumber can last another 100 years. | Modern lumber varied; uPVC has a ~ 20-year lifespan. |
| Thermal Efficiency | Outstanding with draught-proofing and slim-glazing. | Greatest possible rankings with contemporary frames. |
| Environmental Impact | Low (utilizes existing materials). | High (manufacturing and disposal of old frames). |
The Benefits of Professional Renovation
