windows worth preserving
Southwark's SE1 postcode contains some of London's most varied period housing. Victorian terraces line the streets of Bermondsey and Walworth. Georgian townhouses stand near Borough Market and the Thames. Further south towards Elephant & Castle and Walworth, the housing stock shifts again — a mix of periods and property types, many with original timber windows still worth restoring.
Conservation Areas protect much of the borough's architectural character — Bermondsey Street, Borough High Street and the riverside streets among them. Original sash windows are part of what makes these properties worth owning.
Hartwell Sash works throughout Southwark, repairing and restoring original windows on all property types. We understand what these windows need — and how to keep them working properly for years to come.
What we do —
done properly
Every service carried out with care and precision
Draught Proofing
Cold draughts and outside noise reduced significantly — without changing the appearance of your windows. We replace staff bead and parting bead with precision brush pile seals and fit a brush seal at the meeting rail.
Sash Cord Replacement
Windows that slam shut or won't stay open — fixed properly. We replace both sash cords on both sides and rebalance both sashes as standard. One visit, done properly.
Glass Replacement
Cracked, broken or misted panes replaced carefully — preserving the original timber frame. Heritage glass available for Conservation Areas throughout Southwark.
Timber Repair & Repainting
Rotting timber repaired, not replaced wherever possible. Proximity to the Thames means Southwark properties are particularly susceptible to moisture damage — we address the cause as well as the symptom.
Slimline Double Glazing Upgrade
Upgrade single glazing to slimline double glaze units — fitted within the existing frame, preserving the original look entirely. Better insulation, less noise, no change to the character of your property.
Full Sash Replacement
When a window is genuinely beyond saving — we supply and fit heritage timber sash windows made to match the original design of your property. Not uPVC. Timber, made properly.

Working in
Southwark's
protected streets
Much of Southwark sits within designated Conservation Areas. Original sash windows are considered part of the architectural heritage these areas exist to protect.
In many cases, draught proofing, cord replacement and careful like-for-like repairs can be carried out without changing the appearance of the window. For listed buildings, flats, replacement work or properties under specific restrictions, we always recommend checking the correct consent requirements before work begins.
