This involves cutting out rotten sections of wood and replacing them with brand-new, resilient lumber (frequently Accoya or hardwood). Top quality epoxy resins are often used to consolidate softened wood and develop a smooth bond.
4. Glazing and Puttying
If the glass is broken or if the customer chooses to update, the expert will install brand-new panes. Numerous experts now provide "slimline double glazing," which suits existing sash profiles while offering modern-day thermal insulation. Standard linseed oil putty is utilized to seal the glass, preserving the authentic appearance.

| Lifespan | 50+ years with small upkeep. | 20-- 30 years (uPVC breaks down in sunlight). |
| Ecological Impact | Low-- reuses existing products. | High-- manufacturing and disposal of plastics. |
| Thermal Efficiency | Excellent with modern-day draught-proofing. | Outstanding, but often aesthetically compromised. |
| Regulatory Compliance | Normally authorized for Grade I & & II noted buildings. | Often declined by preservation officers. |
