A thorough repair by a sash window professional is a meticulous procedure. It includes more than just a lick of paint; it is a structural and mechanical overhaul.
1. Assessment and Dismantling

3. Draught-Proofing
Among the most considerable upgrades an expert provides is the setup of a peripheral draught-sealing system. This involves machining grooves into the sash beads and conference rails to house brush strips or rubber seals, virtually removing rattles and heat loss.
4. Re-weighting and Balancing
If the glass has been updated from single to double glazing, the sash becomes much heavier. Experts must recalculate the weight and add lead or steel "make-up" weights to the internal pockets to ensure the window stays completely stabilized.
Why Timber Choice Matters
