2. Lumber Restoration
Old paint is stripped away to expose the condition of the wood. Locations impacted by “wet rot” are carved out. Little areas can be fixed using high-performance wood bonding resins, whereas bigger areas of structural damage (typically the window sill) may require “splicing”— where the rotten section is cut out and changed with a brand-new piece of seasoned hardwood.
3. Glass and Glazing
Original cylinder or crown glass has a special “wavy” look that many property owners want to keep. If the glass is broken, it is changed with period-accurate glass or contemporary security glass.

5. Re-balancing and Re-stringing
The sashes are weighed, and the internal weights are adjusted to match completely. New sash cords are set up, ensuring the window operates with “finger-touch” ease.
6. Painting and Finishing
To guarantee durability, the timber is primed, undercoated, and completed with premium micro-porous paint. This type of paint allows the wood to “breathe,” preventing wetness from becoming caught under the surface and triggering future rot.
