Looking after traditional windows doesn’t have to mean replacing them. This guide to sash window refurbishment explains how to restore, repair, and improve timber sash windows across Bristol homes, keeping their original style while improving how they perform. Whether you’re dealing with draughts, stuck sashes, or signs of rot, this step-by-step process will help you understand what’s involved and why refurbishment is often the right choice.
Sash windows are a defining feature of many homes across Bristol, especially in Clifton, Redland, Totterdown, Bishopston, Cotham, and beyond. They carry elegance and heritage but may stop working well over time. A careful refurbishment brings them back to full life, preserving their charm while improving function and comfort.
What Is Sash Window Refurbishment?
Refurbishment restores existing sash windows so they open, close, and seal properly, while retaining the original timber and style. Unlike replacing with modern units, refurbishment keeps authenticity intact, and it often avoids issues around planning restrictions on period buildings.

Step‑by‑Step Guide to Sash Window Refurbishment Process
1. Full Inspection & Removal
We start by removing sashes, cords, and beads. This lets us inspect every bit (from the sill to the sash box) for wear, rot, or misalignment.
2. Timber Repairs & Joinery
Any rotten or cracked timber is replaced or repaired using matching hardwood or Accoya. We splice in new timber where needed to preserve the original style.
3. Sash Cord Replacement & Balance
Old cords often snap or fray. We fit strong waxed-cotton cords and recalibrate sash weights so the windows glide smoothly.
4. Expert Draught-Proofing
We fit discreet brush seals into the parting and staff beads, reducing draughts, rattles, and noise. Visit our Sash Window Draught Proofing page for full details.
5. Reassembly & Adjustment
Once repairs and sealing are done, we reassemble and align components. We make sure sashes slide properly, locks fit, and everything feels right.
6. Painting & Finishing
Weather-resistant paint or stain is applied to seal the timber and enhance its look, bringing your windows back to their former splendour.
