Restoring Architectural Sash Heritage in City Of London
From the Georgian merchant enclaves around Carter Lane, Wardrobe Place, and Temple to mid-Victorian commercial warehouse conversions near Smithfield and Devonshire Square, properties across City Of London feature historic timber box sash windows designed with exceptional architectural nuance.
Headed personally by Charlie Burgess, Eden Sash Windows approaches these windows with timber-first discipline. Decades of heavy paint layers, traffic vibration, and exposure to Thames urban grime frequently leave cords frayed, pulleys misaligned, and lower sill timbers decayed. We focus on in-situ conservation joinery: precision timber splicing, replacement of frayed wax-cotton cords, box frame overhauls, and the discreet addition of acoustic perimeter seals that cut street rumble from thoroughfares such as Fleet Street, Bishopsgate, and Queen Victoria Street.
Internal Refurbishment
Full servicing, unsticking, and cord replacement performed completely from inside the building, eliminating scaffolding costs.
Acoustic Glazing Upgrades
argon-filled double glazing that preserves historic narrow sightlines while deadening intense city traffic sound.
Precision Timber Splicing: Rotted soft timber removed and replaced with seasoned hardwood or Accoya, preserving original interior plaster and external brick reveals.
Timber Window Solutions for City Of London Residents & Freeholders
We only work on authentic timber sliding sash windows, providing long-lasting repairs and compliant upgrades.
Draught Proofing & Overhauls
Eliminate rattles and cold draughts through our concealed brush-pile carrier system machined into new parting and staff beads, preserving visual authenticity.
Double Glazing
Retrofitting double-glazed units (argon-filled, low-emissivity glass, warm-edge spacers) into existing or reproduced timber sashes to comply with conservation requirements.
Soundproofing Upgrades
Crucial for Square Mile residential conversions. Acoustic laminate glass and airtight compression seals cut traffic, siren, and construction noise significantly.
Sash Cords & Rebalancing
Replacement of snapped or tired cords with heavy-duty wax-impregnated cotton sash cord, accompanied by weight recalibration so your sashes glide effortlessly and stay open.
Rotten Sill & Frame Splicing
Surgical removal of rotted timber without tearing out original box frames. We splice durable seasoned timber bedded in two-part epoxy resins, primed and weather-sealed.
Emergency Sash Glazing
Same-day call-outs across City Of London (Mon–Sat 08:00–18:00) for cracked panes, dropped upper sashes, or compromised openings, leaving your property secure.

Our mobile units are fully registered and equipped for central London zones, scheduling deliveries and tool staging cleanly around loading bay restrictions.
Apartments & Mansion Blocks

What an Eden Sash Windows Visit Looks Like in City Of London
When you arrange an initial consultation, Director Charlie Burgess personally carries out the inspection. We examine every component of your sash assembly:
- ✓ Box Frame Integrity: Checking internal pockets, external sill timber, and brick mortar reveals for moisture intrusion or dry rot.
- ✓ Pulley Stile & Counterweights: Ensuring cast-iron or lead counterweights are properly matched to the timber and glass mass, preventing sashes from dropping unexpectedly.
- ✓ Meeting Rails & Glazing Bars: Inspecting historic mouldings, tenon joints, and putty seals for distortion or separation.
- ✓ Acoustic & Thermal Gaps: Measuring perimeter clearances to calculate appropriate brush-pile profiles or double glazing compatibility.
