A thorough restoration by a sash window expert is a careful procedure. It includes more than just a lick of paint; it is a structural and mechanical overhaul.
1. Assessment and Dismantling
The process starts with an in-depth study. Professionals check for structural integrity, wood rot, and the condition of the wheels. The sashes are then carefully eliminated from the frame.

If an area is too harmed, they will perform a "splice repair" utilizing matching wood species such as Accoya or slow-grown redwood.
3. Draught-Proofing
One of the most substantial upgrades a professional provides is the installation of a peripheral draught-sealing system. This involves machining grooves into the sash beads and conference rails to house brush strips or rubber seals, practically getting rid of rattles and heat loss.
4. Re-weighting and Balancing
If the glass has actually been upgraded from single to double glazing, the sash ends up being much heavier. Professionals should recalculate the weight and add lead or steel "makeup" weights to the internal pockets to ensure the window stays perfectly balanced.
