Repair is a meticulous craft that combines standard joinery with modern-day materials. Below is the standard procedure followed by preservation specialists.
1. Assessment and Removal
The procedure starts with the mindful removal of the staff beads and the lower sash. The cables are detached, and the weights are secured. The upper sash is then removed. Each part is labeled to guarantee it goes back to its original position.
2. Paint Removal and Timber Repair
Decades of lead-based paint are typically stripped away to expose the bare wood. Any sections of "soft" or rotten wood are excised. Instead of changing the whole frame, artisans use a mix of brand-new timber "entwines" (using matching wood like Accoya or Douglas Fir) and specialized epoxy resins to reconstruct the profile.
3. Re-glazing and Puttying
If the original glass is intact (frequently recognizable by its captivating "wavy" appearance), it is cleaned and reseated. If the glass is broken, it is changed with recovered period glass or modern slimline double glazing developed to fit within traditional refunds.
4. Draught-Proofing Integration
One of the most considerable upgrades takes place during this phase. Modern brush seals are discreetly machined into the parting beads, staff beads, and the conference rails. This practically eliminates draughts and rattling without altering the window's look.

Does draught-proofing make the windows hard to open?
Rather the opposite. During restoration, the sashes are planed to fit the frame completely, and the brush seals offer a smooth surface area for the window to glide against, often making them easier to operate than before.
Is remediation more pricey than uPVC?
