We're so pleased with how the windows turned out, the refurbished frames look so good. Anecdotally, they seemed to have improved the soundproofing, although we live practically on top of a main road, so does not completely shut out the noise, the casement windows more than the bay windows. Cannot comment on the thermal quality as they were done in the middle of the heatwave, but we are fairly confident there will be a big improvement come winter. Cannot fault the workmen, they were reliable and extremely hard working, even when it was 30C + Would definitely use them again if we ever needed windows to be refurbished in future.Posted on Google![]()

Very happy with the new windows they look fantastic. Keeping the original windows was so important to us and you have made that possible. We only had the upstairs completed and can't believe the difference in the sound and temperature from downstairs. Will be booking the downstairs in ASAP. The team are also fantastic and worked incredibly hard they treated our home with respect and keep evething as clean as they can. I would definitely recommend. Hopefully we will get the same team next time! The neighbours are also asking who done the work and have commented on how hard you worked ! Very happy customers.Posted on Trustindex![]()

Highly recommended for heritage properties A genuinely reassuring experience from start to finish. If you've got a heritage property and you're agonising over who to trust, look no further. Highly recommended.Posted on Yell![]()

Scott James did our restoration work years ago, so when it came time to sort the insulation, there was no question who we'd call. Glad to say they're still the same lot. Still doing things properly. The new VIG glazing has made the house genuinely warmer, and a fair bit quieter too. Lovely to see familiar faces, lovely to see they still take pride in the work. Wouldn't go anywhere elsePosted on Trustindex![]()

Exceptional sash window restoration experience We had a great experience having our sash windows double glazed and draught proofed. We were very impressed by the quality of the work and the team’s craftsmanship from the start. From the initial consultation with Alex right through to the restoration of the windows, the experience was seamless. They were clearly experts in their field.Posted on Google![]()

The end result genuinely surprised us. The original frames have been brought back to life sanded, restored, repainted and the new glazing has made a noticeable difference to both the temperature and the noise from the road. For roughly what secondary glazing would've cost, we've got something that actually looks like part of the house rather than bolted onto it.Posted on Yell![]()

Excellent job, I would highly recommend
Can old casement windows be repaired?
Yes, they can, and repairing original windows is the perfect way of bringing them back to life.
Rather than replacing your windows with modern window replacements that will change the look of your period property forever, repairing your old ones ensures the style of your property goes unchanged.
However, with modern materials, including slime-profile double glazing, we can make your period casement windows as effective against temperature changes and outside noise as any modern window.

What kinds of restoration work can we carry out?
We have all of the window restoration services your project need. We can repair or replace any rotten wood from the window frame, replace any broken glass, replace or repair window furniture and fix any issues with the draught-proofing.
Original windows glazing can also be reglazed with vacuum double glazing to improve efficiency.


Casement window reglazing with double-glazed units
Along with timber frame restoration services, we can also offer upgrades to your window glazing too.
This includes superior draught-proofing and modern double glazing.
We can retrofit double glazing into your existing wooden casement window frames without changing the style of the windows at all.
This is estimated to improve your window’s energy rating from D all the way up to A efficiency.

Reduce noise and improve energy efficiency
Retrofitting double glazing into your old casement windows does a lot of good. It helps improve your home’s energy efficiency (saving you money on energy bills each year) and can reduce outside noise to a whisper.
The double glazing we use in our retrofitting projects is suitable for windows in Grade 2 listed buildings and buildings in conservation areas.
It is just as effective as triple glazing but won’t interfere with how your windows look or operate, thanks to its thickness of just under 7 mm.
Slimline double glazing for casement windows
We use vacuum insulated glazing in our casement and sash window reglazing projects.
This is ultra-thin double glazing that uses vacuum-sealed technology. At just under 7 mm thick, it is one of the thinnest double glazing available, yet it is just as effective at saving energy and reducing noise as triple glazing.


Refurbish rotten casement windows
If you’ve noticed areas of rot on your window frames, you may be thinking that you’ll need to rip them out and replace the frames altogether. You may have even been told the same by another window company in the area.
Well, we disagree. We can refurbish any rotten timber window frames and make them sound.
How do you repair a rotted casement window?
We first start with an inspection of the casement windows in question.
We look at how bad the rot issues are and then recommend the best treatments based on our experience. In many cases, we remove the rotted areas in the wooden frame and splice in brand new wood cut to perfectly fit and match the existing frame.
We can then treat any smaller areas of rot with a rot treatment that kills the bacteria and use high-quality epoxy to strengthen these areas again. After the above work is done, we will laminate the frame with Accoya or Triacoya wood.
Our goal with timber casement window repairs is to make the window frame secure and sound again without changing the style of the window at all. So, any replacement wood we add will look the same after it is painted, and any treatments we do will not change the appearance at all either.
Draught proofing casement windows
Draught-proofing does deteriorate over time, and during all of our window restoration projects, it is something we replace or install if the windows did not have draught seals before.
We use modern draught-proofing as it is far superior to the older stuff. It lasts longer and has performed better over the years.
Again, though, the draught-proofing we use will not interfere with the overall look of your windows or home, but it will keep draughts and energy loss at bay.
Is it better to restore or replace old windows?
In our opinion, it is better to restore the windows you have rather than replace them. Casement windows restoration is often cheaper than replacement, and it won’t change the look of your property at all.
One of the biggest concerns for homeowners with wooden windows is that replacing them will change the look of their property forever.
By restoring the windows and upgrading them with modern materials and window technology, you can be sure that your windows don’t distract from the beauty of your property but are just as energy efficient as any modern window is.
We can help you bring your wooden casement windows into the 21st century without changing their style or your home.
FAQs
How much does it cost to repair a casement window?
Many factors count towards the cost of repairing a casement window. Size, condition, upgrades etc. For an accurate quote for your window restoration, please get in touch.
Should I replace 20-year-old windows?
There is no need to replace a 20-year-old window. We can breathe new life into any timber casement window. If your windows are only 20 years old, likely, they will only need minor repairs, a new coat of paint and a double glazing upgrade to bring them into the 21st century. This will cost less than brand-new double glazing.
How long should wooden casement windows last?
Wooden casement windows can last well over 60 years, and many historic windows around the UK have lasted a lot longer than this. With the right care and protection, your wooden windows will likely outlast your time at the property.
