When sash window replacements are needed
Many period properties still have their original sash windows in place. While sash windows are designed to last a long time, they can become damaged beyond repair over the course of many years, meaning that it will be more economical to have them replaced in full.
These are some of the telltale signs that your sash windows may need to be replaced:
- Excessive rotting timber or lots of damage to window frames
- Windows that are warped, misshapen, or with sashes that no longer fit into the frames
- Significant draughts and cold spots in the room
- Broken glass
- Damage to sash cords
- Damage to the window frame itself
Getting an expert opinion
on your sash windows
It’s difficult to know whether your sash windows need to be replaced or whether a repair is sufficient. Our team can help you decide on the best course of action, using their experience to aid decision-making. One of our skilled surveyors will visit your property, assess the condition of your windows and advise on the most practical and economical course of action. If you need a replacement sash window, we’ll make a bespoke unit and install your windows for the best possible finish.
We can replace existing wooden windows, as well as replace uPVC windows and aluminium windows with timber alternatives, improving aesthetics and preserving character in period properties.

Beautiful new sash windows for your property
We make our sash windows in our very own Sussex workshop, crafting them from quality wood that can last a lifetime. You have the opportunity to pick the exact appearance you want, choosing everything from the type of wood and glazing to the window furniture. If you’re keeping some of your existing doors and windows rather than having a complete property renovation, we can ensure your sash window replacements match them perfectly.
This is what happens if you have beautiful new timber sash windows made by us:
- A surveyor visits your property to assess the condition of your sash windows, answering all your questions. We send you a fully itemised quote for the work suggested.
- If you decide to go ahead, we’ll measure up in full before manufacturing your windows by hand in our workshop. You’re very welcome to visit and see your new windows in the making.
- If required, we arrange a full installation at a convenient time for you. Your windows will be fitted by a skilled carpenter who will ensure the perfect fit.
We love the quality, beauty and longevity of wood and passionately believe it’s the best material to use. Find out more about why wood is the perfect choice for your new sash windows.

The benefits of replacing
vs repairing sash windows
These are some of the benefits you need to know when considering wether to install new sash windows:
- Improved technology
Window technology is improving all the time – older sash windows simply can’t deliver the same kind of performance as modern ones. You can benefit from the latest developments in window technology when you have replacement sash windows made and installed. - Better security
Older, damaged sash windows can be a security hazard and can make break-ins more likely. Replacement windows will be highly secure, with no gaps and new locks. - Reduced draughts
Old sash windows have a reputation for letting in draughts and making properties uncomfortably cold. Our sash windows reduce draughts and cold spots, so there’s no need to worry about this anymore. - Aesthetically impressive
Beautifully crafted, our sash windows make a stunning addition to your property. If you have existing windows and joinery, we can ensure your new ones will be a close match. - Double glazing
When we install new sash windows, we can use the latest double glazing too – we’ll make sure there’s enough room in the frames for the glass.
Upgraded glazing – available with new sash windows
If you require a full replacement, we can install double-glazed sash windows, or you can opt for specialist glazing options such as acoustic glass to help improve your environment. This is because we can make the frames deeper to accommodate the glass and ensure it’s fully effective. Replacement sash windows give you more options to improve your property and lifestyle.
If you have single glazing and you live in a conservation area then you can have double glazing, sometimes even without planning permission. However, if permission is required then we can carry out the whole process for you from beginning to end.
