Casement windows restoration

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 

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.
