4. Glazing and Puttying
If the glass is broken or if the client selects to update, the specialist will install brand-new panes. Numerous professionals now provide "slimline double glazing," which suits existing sash profiles while supplying modern thermal insulation. Standard linseed oil putty is utilized to seal the glass, preserving the genuine appearance.

Key Materials and Tools Used by Specialists
To accomplish a high-standard finish, experts make use of a specific toolkit:
- Accoya Wood: A customized lumber that is practically rot-proof and does not shrink or swell, making it perfect for sills and sashes.
