What customers say
Sash windows restoration in Chelmsford
Wooden windows add charm and elegance to a home, but over time, they can become weathered and damaged.
This deterioration can cause decay and rot, compromising their effectiveness in retaining heat within your home.
Heritage windows, typically single-glazed, are also less energy-efficient compared to contemporary windows. For single-glazed windows, we provide a double-glazing retrofitting service, where we install slim, lightweight vacuum glass into the original frames, replacing the single panes.
Upgrading your home doesn’t have to involve the significant expense of installing new windows. While minor repairs might enhance your home’s appearance, they often provide a temporary solution that may not last beyond three years.
Our window refurbishment service presents a more durable alternative, offering a maintenance cycle comparable to that of a complete replacement. To learn more about our sash window repair process, click here.

Wooden window restorers Chelmsford
At Chameleon, we specialize in all aspects of wooden window restoration and reglazing in Chelmsford and the surrounding villages.
By refurbishing your wooden windows, we not only restore them to full functionality but also enhance their energy efficiency and draught-proofing.
This is achieved by replacing the existing glazing with more energy-efficient Vacuum Insulated Glass (VIG), which also helps to reduce external noise and block UV rays.
Replacement isn’t always an option, especially if you live in a Grade 2 listed property. Unlike restoration, you would need to obtain permission from a conservation officer before you can install new windows, and these new windows would need to match the style and details of your original windows, often requiring expensive custom joinery.
If you’re looking to save money and properly renovate your wooden windows with a guarantee of 20 years on repaired parts and 15–25 years on VIG glazing, you’ve come to the right place.
