Sash window restoration Watford

The chameleon team works throughout Hertfordshire, providing specialist services in wooden window restoration and sash window double glazing retrofitting.

Restoring your wooden windows with Chameleon ensures that your property’s charm is reinstated as we renovate your original windows frames and sashes instead of replacing them with the new ones, even when it comes to double glazing your originally single glazed sashes, in other words, we do a proper retrofitting instead of inserting new sashes into the original box frame.

Above all, our team only use Accoya and Tricoya timber, it is softwood yet it has longer lasting properties than hardwood and as we cover the whole surface of the bottom part with a thin layer of this man-made timber, it shields the original sash window frames timber from the all-weather condition, consequently, your window frames will perform same if not better than new hardwood windows.

Please Note:

Our minimum order quantity is 15 windows.
We do not work as an emergency call-out repair service.

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.
