Unlike modern casement windows that operate on hinges, a conventional sash window includes one or more movable panels, or "sashes," that slide vertically.

A detailed repair by a sash window specialist is a precise process. It involves more than simply a lick of paint; it is a structural and mechanical overhaul.
1. Assessment and Dismantling

2. Removing and Repair
Old paint layers-- which often consist of lead and conceal rot-- are removed away.

If a section is too harmed, they will perform a "splice repair work" utilizing matching timber species such as Accoya or slow-grown redwood.
3. Draught-Proofing
One of the most significant upgrades an expert supplies is the installation of a peripheral draught-sealing system. This includes machining grooves into the sash beads and meeting rails to house brush strips or rubber seals, virtually getting rid of rattles and heat loss.
4. Re-weighting and Balancing
If the glass has actually been updated from single to double glazing, the Bespoke Sash Windows ends up being much heavier. Specialists need to recalculate the weight and include lead or steel "cosmetics" weights to the internal pockets to ensure the window remains completely balanced.
Why Timber Choice Matters
