Timber Sash Window Specialists Serving Borehamwood
Led by Director Charlie Burgess, Eden Sash Windows provides meticulous timber sash restoration, structural box repair, draught-proofing, and double glazing upgrades for period homes across Borehamwood and the northern fringes of the London radius.
Carrying Out Specialist Timber Joinery in Borehamwood
From our workshop base in Battersea (SW8), Eden Sash Windows works across London and its surrounding commuter borders up to 15 miles. For homeowners in Borehamwood, this provides direct access to an authentic heritage sash joiner without having to resort to generic double-glazing salesmen or unsympathetic modern plastic alternatives.
Whether you own an Edwardian railway cottage, an inter-war detached home retaining its original timber details, or a Victorian terrace near key rail corridors, we understand the specific issues affecting local joinery: rattles from passing commuter traffic, draughts through shrink-cracked parting beads, or lower sills rotted through by persistent rainwater run-off.
What a Site Survey in Borehamwood Involves
Every quote starts with a thorough, hands-on survey by Director Charlie Burgess. We take exact measurements down to the millimetre, test timber density with an awl to distinguish superficial surface rot from structural sill decay, check the balance of internal cast iron or lead weights, and assess internal brick reveals. We then deliver a clear, fixed-price written quotation outlining preservation, splicing, or replacement options.
Access and Logistics for Local Clients
We are fully self-contained on site. For projects along narrow residential roads or areas with restricted driveway space in Borehamwood, we organise clean internal dust extraction, protect floor finishes, and carefully stage material deliveries. Wherever possible, we repair sash boxes from inside your home without requiring costly external scaffolding.
Common Sash Works in Borehamwood
- › Rotten Sill Splice Repairs: Cutting out decayed soft wood and splicing in durable new timber sections without pulling out the entire original frame.
- › Concealed Draught-Proofing: Machining hidden nylon brush seals into new staff and parting beads to end window rattles and eliminate cold draughts.
- › Double Glazing: Retrofitting ultra-slim, warm-edge, argon-filled double-glazed units that replicate single-pane sightlines.
- › Cord & Weight Rebalancing: Replacing frayed or snapped lines with wax-impregnated cotton sash cord and matching weights for effortless opening.
Repair First: Protecting Historic Joinery in Borehamwood
Many standard window companies recommend total replacement because it is easier to drop in a factory box. We take a preservation-led approach, saving original timber wherever sound wood remains.
Accurate Timber Splicing
Where rain has settled on external sills or the base of pulley stiles, we rout away the soft fibres back to solid substrate. We then insert matching seasoned timber splices bonded with high-grade structural epoxy, retaining the structural integrity of your box frame.
Box frame repair details →Acoustic & Thermal Sealing
Timber sashes inherently have play between the sashes and the parting slip. Our perimeter brush system fits into machined grooves along meeting rails, top rails, and bottom sills, stopping draughts, reducing railway/traffic noise, and eliminating irritating rattles.
Soundproofing sashes →Bespoke Replacements When Needed
When wood rot is beyond repair or previous owners installed inferior units, we craft bespoke timber sliding sashes. Each frame is manufactured with authentic sash horns, delicate glazing bars, and A-rated double-glazed units with a 10-year guarantee.

If a counterweight cord has snapped leaving a heavy top sash stuck open, or cracked glass has left your property insecure, we provide urgent call-outs from Monday to Saturday, between 08:00 and 18:00. We make the window weather-tight and safe on the day, with permanent joinery work carried out directly after.

Frequently Asked Questions: Timber Sashes in Borehamwood
Do you regularly travel out to Borehamwood for surveys?
Yes. While our primary workshop is based in Battersea (SW8), our 15-mile operating catchment regularly includes clients in Borehamwood who want genuine timber craftsmanship rather than mainstream replacement plastic. Charlie Burgess carries out site visits across this zone.
Can my rotted window sill be saved, or must the whole frame come out?
In the majority of cases, rotten sills can be repaired without removing the outer box frame from the brickwork reveal. We cut back the soft decayed timber to solid wood, treat the remaining frame with fungicide, and splice in a new hardwood sill section bedded in structural epoxy resin.
How effective is your draught-proofing system against train or road noise?
Our integrated draught-proofing system inserts concealed perimeter brush seals into new staff beads, parting beads, and meeting rails. By sealing air gaps, it stops cold draughts and rattles completely, while visibly reducing high-frequency traffic and railway noise.
What warranty do you offer on new bespoke sashes?
All new bespoke timber sash window installations carry a comprehensive 10-year guarantee. As a FENSA-registered installer, our new joinery meets strict thermal, ventilation, and building regulations, providing complete peace of mind.
