Heritage Window Repair Specialists
Original timber windows give heritage homes their defining character. You can't just rip them out and expect the property to look the same. Those centuries-old sash and casement frames carry a level of craftsmanship that modern factories simply don't replicate.
After decades of facing the harsh British weather, problems inevitably crop up. Rattling sashes, snapped cords, peeling gloss, and downright rotten sills are just part of the reality of owning an older property. We firmly believe replacement is an absolute last resort.
Conservation Area Expertise: Our sympathetic restoration approach saves original wood and historic glass wherever possible. Local conservation officers consistently approve our work across London boroughs.
There are many benefits to repairing rather than replacing your period windows, including:
Every job is different, but the process follows the same logic: find out what's wrong, fix only what needs fixing, and leave the rest alone.
If a section of the frame or sill has rotted, we cut back to sound wood, splice in hardwood that matches the profile, and shape it to fit. Once painted, you won't know it was ever touched.
These get damaged more than people realise, usually from years of forced openings or old paint buildup. If beyond saving, we make exact replicas in the workshop.
We strip it back, re-cord the window, clean up the pulleys, and adjust the weights so it balances properly. A well-functioning sash should glide with one hand.
We rout slim channels into the existing timber and fit brush seals. From the outside, the window looks completely unchanged — no plastic trims, no visible additions.
Our repair service specifically targets the issues that drive period homeowners up the wall.
If your period property is in a London Conservation Area or is Grade II Listed, strict regulations govern exterior changes. Our methods comply with Article 4 Directions and are consistently approved by local conservation officers.
Deciding whether to repair your original timber windows or invest in full replacements is a major decision. At Golden Ratio Windows, we believe in preservation first — but we also recognise when a window is beyond a cost-effective fix.
We have extensive experience working in conservation areas including Islington, Hackney, Camden Town, Highbury, and Stoke Newington.
