You might need to restore or replace your sash window for many reasons. Wear and tear, improving energy efficiency, or simply breathing new life back into your property.
Restoring windows entails repairing or refurbishing existing windows, and this is most commonly deemed necessary if the timber is rotting or the frame has been damaged in some way.
Replacement, on the other hand, would involve removing the entire old window and fitting it before replacing it with an entirely new window.
There are several considerations you’d want to make in deciding whether to restore your old sash window or replace it; the condition of the windows, the cost, and their energy efficiency, to name a few. So, let’s explore those…
Condition Of The Windows
The condition of your home’s windows can be a big factor in deciding whether to restore or replace them. If your windows only have minor damage from wear and tear, then it may be easier and more cost-effective to look at repairing them.
On the flip side, if there is serious structural damage or rotting and warping, replacing them can prevent further structural damage and ensure integrity. Making sure to do a thorough assessment of the state of your windows will inform any decision on whether you go for sash window installation or repair.
Historical Significance
Lots of homes in the UK are Grade I or Grade II listed. In these cases, restoring the original windows may be a necessary option over replacing them: often, keeping the original fittings is a requirement for these houses.
Regardless of this, if your property was built in a particular architectural style – for example, Georgian or Victorian – you may want to restore the original windows regardless. It will help maintain the character and personality of your home. Restoring your windows will retain as much of the original timber as possible.
Replacing the window may be a better option if the design of the rest of the property has been changed, however. It may be the case that replacing the window with a more modern design will better fit the aesthetic of the rest of your home. Whether replacing or restoring your windows is better for your home’s style is therefore a case-by-case basis.
What Is Your Budget?
Cost can be a deciding factor for whether to replace or restore your windows. Restoration can often be a far more affordable option and is particularly good when your windows only require minor repairs.
This means in cases where the window can be restored, and the budget is lower; it can be the more appealing option. Of course, this is dependent on whether the window is in a state where restoration is an option. If extensive repairs are required for major damages or rot, then repairing the original window can actually cost more.
Moreover, the upkeep on a restored window will be more than a new replacement.
A restored window will remain more susceptible to wear and tear, which could lead to further costs down the line. Modern replacement windows are made of materials which are more durable and long-lasting.

Cost Estimates
In the UK, the average cost of sash window restoration varies depending on the amount of work required. Generally, it can cost anywhere from £500 up to £2000. For a complete sash window refurbishment, the cost ranges between £620 to £920 and takes one day to complete. If your sash windows need significant repairs or an upgrade from single to double glazing, the restoration cost will increase significantly.
When it comes to sash window replacement, the cost depends on factors such as materials used, size of the windows, and whether double glazing is included. On average, it costs between £500 and £800 to install uPVC sash windows in the UK. However, the cost of replacing sash windows with double glazing starts at £1,300 per window.
Energy-Efficiency
Older windows might not be as energy-efficient as a new replacement. Modern windows reduce heat loss from your home, which in turn means you’ll be burning less fuel to keep it warm. This will cut the costs of your energy bills over time, as well as lessening the environmental impact of your home.
However, if you opt for restoration, it is still possible to improve the energy efficiency of your windows. In the restoration process, double glazing can be installed, reducing heat loss.
Likewise, draught-proofing can be installed to help keep your home warm. This will often incur an additional cost to the restoration itself.
Case By Case Basis
Ultimately, there are many factors which will determine whether it is better for you to restore or replace your sash windows.
The current condition of the windows and your budget will be crucial in your decision, as these will determine both practically and financially if restoration is the better option. However, it is also important to consider whether replacing the windows will still retain the character of your home, and energy efficiency is also a consideration.
If you’re unsure which option is best for your home, consulting a professional window specialist to assess your windows and make a recommendation is best.
