Period sash windows in Romford — the problems we get called about
Romford's housing stock spans Victorian and Edwardian around the market-town core, the Gidea Park garden-suburb conservation area to the north-east, and the long interwar runs that push out toward Hornchurch, Upminster and Harold Wood. The original timber windows have done a century of service and are showing it.
We specialise in sympathetic refurbishment — traditional joinery alongside discrete modern improvements that preserve the original window whilst making the rooms easier to live in. Twenty-five years of work on sash and casement frames, across east London and the surrounding Home Counties.
What we see most often in Romford houses:
- Rotting cills and stile bottoms — water sitting on horizontal timber over decades.
- Heat loss through single glazing — a typical U-value around 5.0 W/m²K, against a modern wall at ~0.3.
- Persistent draughts and rattling from worn parting beads and meeting-rail seals.
- Noise from the A12, the A127, and the Crossrail/Elizabeth-line corridor.
- Sash cords gone or weights unbalanced, so the window won't stay open.
Refurbishing wooden windows in Romford
Wooden sash windows need proper care to keep their function and their look. Our refurbishment focuses on the parts that have actually failed — frames, cords, weights, glazing bars — without touching what's still doing its job. The frame stays, the glazing bars stay, original glass stays where it survives.
Cords, weights and balance
Over time, sash cords weaken and break, and the rebalance gets off as the weights wear into their pockets. We replace damaged cords (nylon-blend for durability) and adjust counterweights so the window operates smoothly and stays where you put it. Where the retrofit adds glass weight, we rebalance to match.
Glazing bars and muntins
Delicate timber components — glazing bars, astragal mouldings, muntins — can deteriorate with age, particularly on south- and west-facing elevations where UV does its work. Where they've failed we repair or replace in matching profile, preserving authenticity rather than substituting a generic section.
Frame and cill repair
We splice-repair decayed timber: cut out the rot back to sound wood, scarf in matched joinery, treat the surrounding timber, prime and paint. The deeper jobs we cover in our rotten sill repair guide.
Double-glazing retrofit for Romford sash windows
Older sash windows in Romford contribute to heat loss and rising energy bills. The retrofit drops the U-value at the glass from ~5.0 to ~0.7 W/m²K — triple-glazed thermal performance inside an 8 mm vacuum-insulated unit, fitted into the existing sash frames.
The retrofit also cuts external noise meaningfully — particularly the rumble from the A12, the A127, and the rail corridor. The original line of the window is preserved: glazing bars, horns, proportions all stay, which is essential for Gidea Park conservation area properties.
Glazing options
The right glazing depends on what the house needs:
- Vacuum-insulated glass — 8 mm unit, ~0.7 W/m²K, best thermal and acoustic, slimline enough for conservation work.
- Slim-profile double glazing — 14 mm, lower cost, where the frame can accept the extra rebate depth.
- Laminated acoustic glass — added for properties sitting close to the A12 or A127, where noise is the priority.
We walk through these at the survey and write up which one fits your house and your priorities.

Frequently asked questions
Can existing Edwardian sash windows be upgraded with double glazing?
Yes. We install vacuum-insulated double glazing into the existing sash frames, improving insulation and acoustic performance while keeping the original sightline and the original sash in place.
Do you work in the Gidea Park conservation area?
Routinely. Vacuum-insulated retrofit is the usual specification because nothing visible changes — the original sightline, glazing bars and putty profile all stay. We handle the planning paperwork where Havering asks for it.
What's the cost of refurbishing a sash window?
Refurbishment runs from around £800 per window for a basic rot-and-paint job; with the vacuum-insulated retrofit the full package runs from £1,200, typically £1,200–£1,700 depending on the glass specification. The survey produces an itemised written quote for your specific property.
