01

How we restore your sash window mechanism

Our repair process is designed to be as non-destructive as possible. We carefully open the internal box pockets of your sash frames to access the pulley system. We remove the old, degraded ropes and install high-quality, wax-impregnated cotton sash cords, which are selected for their durability and authentic performance. This approach ensures that your original timber frames remain intact while restoring full functionality.

02

Precision rebalancing for your period windows

A successful cord replacement is only half the job; the window must also be properly balanced to ensure it stays in place when opened. We carefully inspect and rebalance the original cast iron or lead counterweights to match the weight of your sashes. During this service, we also examine the condition of the pulley stiles and parting beads to ensure every element of the mechanism works in harmony, preventing future binding or dropping.

03

Heritage-sensitive repair for Westminster homes

Whether you live in a Victorian terrace or a grand Georgian townhouse in Westminster, we understand the specific joinery requirements of your home. Our work adheres to the high standards expected in historic urban areas, prioritising the preservation of existing timber over unnecessary replacement. By maintaining the integrity of your original boxes, we help ensure your home retains its character while providing modern, reliable window operation.

04

Same-day help for urgent sash cord repairs

A snapped cord or a dropped sash can leave your window stuck or unsecured. We offer a dedicated, same-day response service between 08:00 and 18:00, Monday to Saturday, for these urgent situations. If your window requires immediate attention to remain secure and weather-proof, call us to schedule a visit. For standard maintenance, we provide a detailed sash survey and a clear, written quotation to ensure you know exactly what is required. Book your survey today by calling 020 7046 0157.

"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.
