High-quality sash window weights
Traditional sash windows rely on a carefully balanced counterweight system to operate correctly. The sash window weights are connected to the window sash using sash cords or other appropriate hardware and provide the counterbalance needed to allow the sash to move smoothly.
When sash weights are damaged, missing, incorrectly sized or replaced with unsuitable alternatives, a sash window may become difficult to open and close. The sash can feel too heavy, drop unexpectedly, fail to remain in position or put unnecessary strain on the cords and other components.
Choosing the correct sash weights is therefore an important part of sash window repair, restoration and installation.
Our sash weights are manufactured and supplied with accuracy and durability in mind, making them suitable for a wide range of traditional and modern sash window applications.
Sash weights for window restoration & replacement
We supply replacement sash window weights for a variety of restoration and refurbishment projects.
Our products can be used when:
- replacing damaged or corroded sash weights
- restoring Victorian sash windows
- refurbishing Edwardian sash windows
- repairing traditional timber sash windows
- replacing missing sash weights
- balancing newly restored window sashes
- upgrading or repairing existing sash window systems
- manufacturing or installing replacement sash windows
- carrying out period property renovations
- restoring listed or heritage properties where appropriate
For restoration work, selecting the correct sash weight size and material is particularly important. The weight needs to provide the appropriate counterbalance for the window sash so that the completed window operates smoothly and safely.
If you are unsure which sash weights you require, contact us with the dimensions and requirements of your project and we can advise on the most suitable option.
Lead & Steel Sash Window Weights
We offer a variety of lead and steel sash window weights, including cut-to-order options in Greater London.
Different sash window systems and restoration projects require different weight specifications. Our range of metal sash weights allows customers to select a suitable solution based on the required dimensions, material and weight.
Lead Sash Weights
Lead sash weights are traditionally associated with many older sash window systems. Lead has a high density, allowing a relatively compact sash weight to provide substantial counterbalancing force.
This can be particularly useful where the available space inside a traditional sash window box is limited.
Steel Sash Weights
Steel sash weights provide a durable alternative for sash window applications where steel is preferred. Steel weights can be manufactured or supplied in a range of sizes to accommodate different sash window requirements.
Whether you require lead sash weights, steel sash weights or another bespoke metal solution, we can help identify an appropriate option for your project.
Cut-to-order Sash Window Weights
Not every sash window uses the same size or weight of counterbalance. This is why we offer cut-to-order sash window weights to help customers achieve the specification required for their particular window.
Our cut-to-order service is suitable for both smaller domestic restoration projects and larger professional requirements across London and Greater London.
If you are replacing existing sash weights, it is useful to establish the required weight before ordering. Depending on the window design, the required counterbalance may depend on the weight and configuration of the sash itself.
For professional window restorers, joiners, builders, contractors and property owners, accurately specified sash weights can make a significant difference to the final performance of a restored window.
Sash Weights for victorian & edwardian windows
Traditional sash windows are a defining feature of many properties across London. Victorian and Edwardian homes often retain their original timber sash windows, but decades of use can result in worn sash cords, damaged weights and poorly balanced window sashes.
Replacing the sash window weights can form an important part of a wider sash window restoration.
We supply sash weights suitable for restoration projects involving traditional timber windows, helping preserve the appearance and functionality of period sash window systems.
For heritage and period properties, maintaining the correct traditional operating principle can be an important consideration. Our sash weights provide a practical solution for projects where the existing counterweight system needs to be repaired, replaced or recreated.
How sash window weights work?
A traditional weighted sash window uses a counterbalance system to make the window easier to operate.
Typically, the sash is connected to a weight using a cord or related mechanism. The sash window weight moves within the window box as the sash is opened or closed. When correctly specified, the counterbalance helps offset the weight of the sash and allows it to remain in position.
The correct sash weight is therefore essential to achieving good window balance.
If the weight is too light, the sash may not remain securely in the desired position. If it is too heavy, the sash may become difficult to operate or may behave unpredictably.
For this reason, choosing the correct sash weights is an important consideration when repairing or restoring traditional sash windows.

Replacement Sash Weights for Sash Window Repairs
Old sash weights can become damaged, inaccessible or unsuitable during a window restoration. In some cases, previous repairs may also have resulted in incorrect or mismatched weights being installed.
Replacing the existing weights with correctly specified sash window weights can help restore the intended balance of the window.
When planning a sash window repair, it is important to consider the complete operating system, including the sash, cords, pulleys and counterweights. The correct combination of components helps ensure that the window operates smoothly and that the sash remains properly balanced.
We can supply replacement sash weights for projects where existing weights need to be replaced or where new weights are required as part of a complete restoration.
