Our Repair & Restoration Process
1) Free Survey & Advice — We examine timber condition, mechanics and glazing, check for conservation constraints and agree priorities.
2) Careful Strip-Down — Sashes are safely removed; furniture, cords and beads catalogued. We protect floors and decor throughout.
3) Specialist Timber Repairs — Rot is cut back to sound wood; we splice in matching sections and treat for longevity. Loose joints are re-glued and pegged.
4) Rebalance & Re-cord — New sash cords and pulleys; weights rebalanced for smooth, fingertip operation.
5) Draught-Proof & Glazing — Discreet brush seals; new putty lines; optional acoustic/thermal glazing (subject to conservation rules).
6) Finishing & Sign-Off — Reassembly, hardware refit, smooth travel checks and a tidy handover.
Hampstead Case Study
A late-Victorian terrace near Hampstead Heath (NW3) had six original sashes with heavy paint build-up and rotten sills. We spliced new hardwood sills, re-corded and rebalanced all sashes, added discreet draught seals and restored putty lines. Operation was restored, rattles eliminated and rooms felt warmer with noticeable noise reduction from the street.
Conservation & Listed Buildings
Much of Hampstead falls within conservation areas. Our methods are designed to retain original fabric wherever possible. Where consent is required (e.g. glass changes or profile alterations), we prepare specifications that respect historic proportions and sightlines so proposals are more likely to be approved. If your home is listed or within a conservation area, we’ll advise on the most sympathetic approach.
Draught-Proofing & Energy Performance
Old sash windows often leak air around the meeting rails and parting beads. Our discreet brush seals and careful refitting significantly reduce draughts without changing the appearance of your windows. Where appropriate, we can discuss slimline double glazing, secondary glazing or improved putties to enhance comfort while preserving character.
