01

How we restore your sash window movement

The process begins with a careful inspection of your internal box frame. We remove the staff and parting beads to gain access to the weights and pulleys hidden within the frame. Our team replaces old or snapped cords with durable, wax-impregnated cotton sash cords. By adjusting the lead or cast iron counterweights to perfectly match the weight of your specific glazing, we ensure the sashes glide effortlessly rather than jamming or sliding shut unexpectedly.

02

Why choose professional sash cord replacement in Swanley

Sash cords are the unsung heroes of your windows, and when they fail, it often leads to dropped sashes or damaged timber frames. Beyond simply swapping out the cord, we check the pulley wheels for wear and ensure the pulley stiles are clear of debris. This careful maintenance prevents unnecessary strain on the sash stiles and meeting rails, protecting the long-term structural integrity of your windows.

03

Can draught proofing be integrated with window rebalancing

Yes, we often recommend installing hidden brush seals during the rebalancing process. These are machined into the new parting and staff beads, creating a discreet barrier against wind and street noise. This improves the thermal performance of your home without altering the authentic profile of your timber sashes, making it an ideal upgrade for historic homes in Swanley and Sevenoaks.

"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."

Sash Rebalancing & Cord Repair FAQs

Frequently Asked Questions

Specialist advice from Charlie Burgess on sash cord replacement, counterweight balancing, and restoring effortless timber glide across South London.

Why does my sash window fall down as soon as I let go?

+

This usually happens because the sash cords have snapped or the counterweights inside the box frame are too light for the sash. It is a common issue in Victorian terraces where years of repairs might have resulted in the wrong weights being used. Charlie Burgess can open the box frame, re-thread it with durable wax-cotton cord, and rebalance the lead weights so the window stays open safely.

Can you rebalance my windows if I upgrade to double glazing?

+

Yes. This is a vital part of the upgrade process. Because double-glazed units are heavier than single glazing, the original weights will no longer be enough to hold the window up. We calculate the new weight of the sash and add lead "make-up" weights or swap iron weights for denser lead ones to ensure the window remains easy to operate.

Do I need to replace the whole box frame if the window is stuck?

+

Rarely. Most "stuck" windows are simply painted shut or have seized pulleys. We can usually restore the window by carefully stripping back the paint, replacing the pulley wheels, and re-hanging the sashes on new cords. This is far more cost-effective and sympathetic to your property’s heritage than a full replacement.

How long does it take to fix a snapped sash cord?

+

A standard cord replacement and rebalance usually takes a few hours per window. We work cleanly and efficiently from the inside of your property, meaning we rarely need scaffolding for this type of repair, even in mansion flats or first-floor rooms.

Do you offer a guarantee on your sash repairs?

+

While cord replacement is a maintenance task, all our new bespoke timber window installations come with a 10-year guarantee and FENSA certification. For repairs and restoration, we use the highest grade materials, such as seasoned timber and heavy-duty cords, to ensure your windows function perfectly for years to come.
