A thorough remediation by a Sash Window Repair Specialists window professional is a careful process. 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 a specialist supplies is the setup of a peripheral draught-sealing system. This includes machining grooves into the sash beads and conference 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 been updated from single to double glazing, the Sash Window Repair ends up being heavier. Specialists must recalculate the weight and include lead or steel “makeup” weights to the internal pockets to make sure the window stays perfectly balanced.
