Victorian Sash Window Repair

This attractive double-fronted Victorian property was in dire need of some window restoration with original period windows. Some of the more seriously rotten windows were laminated with tricoya which is a timber offering exceptional longevity and rot resistance.

If you live in Essex and are looking to update or repair your wooden sash windows, then you have come to the right place.

With decades of experience repairing Sash and Casement windows, we at Chameleon are experts in wooden window restoration, transforming your damaged or weather-beaten windows to their former beauty.

Wooden sash windows come with great charm but after years of wear and tear they can become less effective, causing rot, draughts, rattling and heat loss.

If you are tempted to replace your old windows, an extremely costly and time-consuming exercise, we offer a far better alternative.

Window restoration will save you money, improve the look and functionality of the most derelict windows, protect them and keep the sentiment of your home intact.

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!

Vanessa Nash

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!

Sarah Mayne

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!

Oliver Taylor


Very pleased with the results, very professional service. Would recommend.

Stephen Mcmullen

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.

Jamie Newman

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.

Frequently asked questions

What kind of wood do you use?

In our timber window restoration projects we use Accoya and Tricoya wood. Accoya wood is a type of modified wood that is produced through a acetylation process. This process involves adding acetic anhydride to the wood, which modifies the cell structure and makes the wood more resistant to rot, pests, and decay. Accoya wood is often used in high-end furniture and cabinetry, as well as in exterior applications such as siding, decking, and fencing. In addition to its durability, Accoya wood is also environmentally friendly, as it is made from sustainable sources and can be recycled at the end of its useful life.

Do you repair windows on Grade 2 listed buildings?

We work with lots of sash windows in Grade 2 listed buildings and conservation area properties. We do like-for-like timber frame repairs that don’t require planning permission as we do not change the style of the existing windows.

Can you free stuck or painted-shut sashes?

Sometimes a window’s sash cords are compressed or tangled and cannot move freely. In this case, we’ll clear out any paint from the stuck surface so you can open your windows without issue! We’ll either remove the problem paint during restoration or change out cords and weights if needed so that they will function properly for years of use!

What is the lead time to get the exterior window renovation work done?

Generally speaking, a 15 window project will take us 5-7 days.
