01

How We Restore Your Window Mechanism

The restoration process begins by carefully accessing the internal box pockets of your window frame. I remove the damaged, worn-out cords and replace them with high-quality, wax-impregnated cotton sash cords. These materials are chosen specifically for their durability and authentic performance in historic timber frames. This work is performed with precision to ensure your sashes operate as intended, whether they are original Victorian features or later period designs.

02

Rebalancing Weights for Smooth Operation

Simply replacing a cord is often not enough to restore full functionality. During the repair, I thoroughly inspect and rebalance the lead or cast iron counterweights hidden within your box frames. If the weights are not correctly matched to the weight of your sashes, the window may drift or become difficult to manage. I also check the condition of the pulleys and parting beads to ensure the entire mechanism is free of obstruction.

Why Choose Local Heritage Joinery in Surrey?

Living in a period home in Surrey requires a careful touch, especially when dealing with original timber joinery. Unlike modern alternatives, our approach focuses on repair and maintenance of the existing structure. By retaining your original box frames and timber sashes, we maintain the authentic aesthetic of your property while resolving the mechanical issues caused by time and use. This commitment to traditional craftsmanship is at the heart of every job I undertake.

04

Do You Need Urgent Sash Repairs?

A dropped or stuck sash can be a significant inconvenience, particularly if it leaves your home vulnerable to the elements. If you are experiencing an urgent issue with a snapped cord or broken glass, I provide a responsive service to secure your windows. We offer same-day support between 08:00 and 18:00, Monday to Saturday, across Caterham and the wider area. If a permanent repair cannot be finished during the initial visit, I will ensure your window is safely boarded and weatherproofed before returning to complete the joinery work.

Why Choose Eden Sash Windows?

Led by Charlie Burgess from our Battersea workshop, we restore effortless movement to period timber sashes across Westminster and London using traditional wax-impregnated cords and precise counterweight balancing.

We install pre-stretched, heavy-duty wax-impregnated cotton cords with high-tensile cores, designed to resist friction, snapping, and internal rot within the box frame.

Calibrated Weight Rebalancing

We calculate sash weights and match lead or cast-iron counterweights precisely, servicing original axle pulleys so your sashes hold position and glide smoothly.

Careful Heritage Box Access

Pocket covers are opened cleanly without damaging staff beads, parting beads, or interior plaster reveals, preserving the historic joinery of period properties.

London & Westminster Specialists

"We are very happy with Eden Joinery's work: we had a completely new sash fitted, and four sashes fitted into our existing frames. Our windows look fantastic - and no more draughts! Terry and son were courteous, tidy, with competitive rates, and took obvious pride in their work. They went the extra mile to fix a problem with one of our frames, and all windows were finished to a high standard. We would not hesitate to recommend them."

Frequently Asked Questions About Sash Cord Replacement

Expert advice on snapped cords, counterweight rebalancing, and timber box frame servicing across South London.

Do you need to take the whole window out to fix a snapped cord?

+

We do not need to remove the entire box frame from the wall. We carefully remove the internal timber staff beads and the sliding sash itself to get to the "pocket pieces" in the side of the frame. This gives us access to the weights. Because we are specialists, we do this with minimal disruption to your interior paintwork or wallpaper.

Can you fix a sash window that has dropped or won't stay up?

+

Yes. This is usually a weight rebalancing issue. If a window has been repaired poorly in the past, or if the glass was replaced with a heavier version, the internal counterweights will be too light. We calculate the exact weight required and add lead make-weights to the system so the sash stays exactly where you leave it.

Is it worth draught-proofing while replacing the cords?

+

We highly recommend it. Since the window is already dismantled to replace the cords, adding a draught-proofing system is very cost-effective at this stage. It involves fitting discreet brush seals that close the gaps where air usually leaks through, significantly reducing street noise and heating bills in South West London homes.

What areas do you cover for emergency sash repairs?

+

From our Battersea workshop, we cover all of South West London and parts of Surrey within 15 miles. This includes Wandsworth, Lambeth, Richmond upon Thames, Merton, and Kingston. If you have a dropped sash or broken glass that leaves your property unsecure, we offer same-day emergency repairs from Monday to Saturday, 08:00 to 18:00.

How long does it take to service a single window?

+

Replacing the cords and rebalancing a single window typically takes between one and two hours. If you are having a full service including draught-proofing and pulley maintenance, it may take a little longer. We always provide a clear, written quotation after a survey so you know exactly what to expect.
