1. Assessment: A thorough survey to recognize rot, structural damage, and hardware performance.
2. Dismantling: Careful elimination of personnel beads, parting beads, and the sashes themselves.
3. Paint Removal and Repair: Stripping layers of old lead-based paint and using epoxy resins or "splice" repair work for damaged lumber.
4. Balancing: Re-weighing the sashes and adjusting the internal weights to guarantee the window "floats" effortlessly.
5. Draught-Proofing: Installing discreet brush strips into the beads and conference rails to remove rattles and cold air.
