Expert Sash Window Repair & Draught Proofing in London
Stop window rattles and reduce energy bills. Golden Ratio Windows provides heritage-grade restoration for Victorian and Georgian timber windows across London.
Why Do Sash Windows Rattle?
Sash windows are a triumph of Victorian and Georgian engineering, but they rely on precision. Over decades, timber shrinks and layers of old paint build up, creating gaps between the sashes and the beads. This doesn't just cause that irritating "clatter" during a storm; it leads to:
- Significant Heat Loss: Gaps act like a vacuum, pulling expensive heat out of your home.
- Street Noise: If air can get in, so can the sound of London traffic.
- Dust & Pollution: Gaps allow urban particulates to settle on your furniture and sills.
Our Restoration & Silencing Process
We don't just "fix" windows; we re-engineer them using a blend of traditional joinery and modern performance technology.
- Dismantle & Inspect: We carefully remove the staff beads and sashes to inspect the hidden inner workings.
- Weight Balancing: We re-balance the internal lead or iron weights so your windows open with a single finger.
- Cord & Pulley Service: We replace worn cotton cords with waxed sash cord or nylon-core variants for longevity.
- The "Secret" Seal: We machine discreet grooves into the beads to install high-performance brush seals.
- Timber Repair: Any localized rot is treated with architectural-grade epoxy or spliced with matching hardwood.
- Final Fit: We reinstall the sashes, ensuring a "snug" fit that eliminates movement while allowing effortless sliding.

Cord & Pulley Repair
We replace snapped sash cords with high-durability waxed cotton or nylon-core ropes and service pulleys for effortless sliding.
Sill & Timber Resins
Using architectural-grade epoxy resins, we repair localized wood rot in sills and box frames, preserving the original fabric of the window.
Re-Balancing
We calculate the exact weight of your glass to ensure internal lead weights are perfectly balanced for "one-finger" operation.

The Golden Ratio Restoration Standard
Restoration is a sustainable alternative to replacement. Our process involves stripping back decades of paint, treating 100-year-old Pitch Pine or Oak with modern preservatives, and integrating discreet draught-proofing systems. This ensures your Victorian or Georgian windows meet 21st-century thermal standards while remaining architecturally correct for Grade II listed buildings and conservation areas.

How do I stop my sash windows from rattling?
The most effective way to stop sash windows from rattling is through professional draught-proofing. This involves installing high-performance brush seals into the window beads, replacing worn parting beads, and re-balancing the internal sash weights. This eliminates the gaps that cause noise while improving insulation.
Frequently Asked Questions
Can you fix the rattle without replacing the whole window?
Yes. Replacement is rarely necessary. Our restoration service focuses on the "perimeter" of the window. By replacing the beads and installing draught-proofing, we eliminate the rattle while keeping your original 100-year-old timber intact.
How long does the repair take?
Most London sash windows can be fully serviced, draught-proofed, and silenced in a single day, causing minimal disruption to your home life.
Will my windows be harder to open?
Quite the opposite. Part of our process involves cleaning the pulley tracks and re-waxing the channels. Your windows will glide more smoothly than they have in decades.
