- Excessive Draughts: Gaps in between the sashes or around the beads that permit cold air to go into.
- Rattling: Loose-fitting sashes that move when the wind blows or traffic passes.
- Functional Failure: Windows that are painted shut or have snapped sash cables.
- Lumber Decay: Dark spots, soft wood, or flaking paint, especially on the bottom rail or window sill.

3. Re-glazing and Upgrading
If the homeowner picks, the initial single glazing can be changed with "Slimline" double glazing. This includes routing out a much deeper channel in the existing timber to accommodate a vacuum-sealed unit that provides modern thermal performance without changing the window's profile.
4. Re-balancing the System
The weight of the sashes must be completely balanced by the lead or iron weights hidden within the sash box. If the glass has actually been upgraded to a heavier double-glazed system, the refurbishment business will include extra weight to the internal counterbalances to ensure smooth operation.
5. Draught Proofing
This is maybe the most essential action for modern convenience. Machined grooves are cut into the beads and the meeting rails to house brush stack seals. These seals close the gaps that traditionally permitted heat to leave and dust to get in.
6. Completing and Re-installation
The windows are sanded, primed, and painted with micro-porous coatings that enable the wood to breathe. Lastly, the sashes are reinstalled with new cords and premium brass or chrome ironmongery (locks, lifts, and fasteners).

- The Staff Bead: The internal frame molding.
- The Meeting Rail: Where the 2 sashes meet in the middle.

Glazing Options
While some owners choose to keep the initial "wavy" crown glass for its historic authenticity, lots of opt for thermal upgrades.
- Acoustic Glass: Specialized laminate glass that decreases decibel levels, perfect for hectic city center properties.
