Unlike contemporary casement windows that operate on hinges, a traditional sash window consists of several movable panels, or "sashes," that slide vertically.

A thorough repair by a sash Window experts window expert is a meticulous procedure. It includes more than just a lick of paint; it is a structural and mechanical overhaul.

Among the most considerable upgrades an expert offers is the installation of a peripheral draught-sealing system. This involves machining grooves into the sash beads and meeting rails to house brush strips or rubber seals, essentially eliminating rattles and heat loss.
4. Re-weighting and Balancing
If the glass has actually been upgraded from single to double glazing, the sash becomes heavier. Experts should recalculate the weight and include lead or steel "cosmetics" weights to the internal pockets to make sure the window stays completely stabilized.
Why Timber Choice Matters
