Unblocking stuck or painted shut sash windows
Broken or snapped cord replacement
Sash window weights rebalancing
Restrictors and stops installation
Rotted frames or cracked paint may not affect your immediate comfort as much as stuck sash or sash that does not stay open or closed due to failed mechanisms. That is why it’s important to restore the functionality of your windows while repairing frames and upgrading glass.
Sash windows operate on a weight and pulley system that creates a counterbalance with the window, allowing smooth movement between its open and close position. Consequently, any issue with the weight or pulley can make the sash window tricky or even impossible to open. For tasks such as this or any other restoration work that your windows may need, our team will have them fully functioning once again.
We do not operate as an emergency call-out service, but we can repair cords or pulleys as a part of a timber frame restoration or double-glazing installation project.

For owners of Georgian or Victorian properties with old timber windows, it is always a tough decision whether you should replace or refurbish your sash windows.
At Chameleon, we believe that renovating old box sash windows is the way to go, to preserve the character of beautiful Georgian properties.
We also believe that renovation provides you with far better value than replacement.
We often get asked if we work with other types of timber windows rather than just sash and our answer is yes. We work with all styles of timber frame windows, including casement, French door, and sliding window.
As long as the window has a timber frame and glass, we can refurbish it by fixing the frame, removing rot and replacing it with solid timber and restore functionality.
In many historic buildings, bay windows are made in custom sizes, styles and are expensive to replace if you are also looking for a like for like replacement.

Really pleased with our windows! Prompt and helpful communication, extremely hard working team and a great looking (and hopefully better functioning) end result. Thank you!
Alex and the team have restored our 20 year old sash windows so they look brand new. The team worked non-stop to complete it and made sure everything was to an excellent standard. Thank you.
We’re very happy with the work we recently had completed on the windows. It was also done in great time, with the guys coming nearly every day, including weekends – absolute grafters. Thank you, our windows look great!
We had an excellent experience with Chameleon Decorators. The work was completed on time and to a very high standard throughout, all at a fair price. Would have no hesitation in providing a recommendation. Please note that the team work on the exterior only so you will need to factor in an internal job also!
Very pleased with the results, very professional service. Would recommend.
Excellent communication, service and professionalism. We spoke with Chameleon to restore some rotting wood french doors and wooden windows, as well as redecorate. We’d use them again without hesitation and would thoroughly recommend them.
Alex and his team are superb. We have used them before, and always been impressed – as we were this time – by their work ethic, their expertise and knowledge, the quality of their work, and their efficiency. I recommend them very highly indeed.
Sash window restoration work starts at £500 per window. The cost will depend on several factors such as the window size, whether it requires glass or sill replacement, draught-proofing installation, functional restoration etc. The cost also depends on the number of windows and access to them. If you live in a busy high street with limited access to the windows, the cost per window will be significantly higher.
Generally speaking, a 15 window project will take us 5-7 days.
