Here are top 9 issues
we deal with every day

wooden casement windows under restoration

Decayed window sills

wooden windows with Rotten beading

Rotten beading

Partially decayed frame

Loose putty

Rain water penetrates unprotected wood through cracks in putty

Cracked glass pane

We replace all cracked glass before commencing the wood repairs

Recently painted windows

Often rotten wood is left untreated under a fresh coat of paint. It leads to even more expensive repairs being needed in the future.

Holes in sash window frames

Despite the scary appearance, we repair these on a daily basis

Missing putty
and rotten bottom rail

Where necessary we will replace badly rotten window parts

Wet, partially rotten sills

Stripped back to solid wood, the sills will be treated and repaired with Accoya/ Tricoya wood

Here is a quick insight into our approach

The most vulnerable area of any window is its bottom part and a sill, where all moisture gathers. We remove all rot, treat affected areas with wood hardener and carefully repair the window with resinous fillers and Accoya wood

We also use around 25 boxes of different tools during windows restoration projects

The Process of repairing wooden
sash & casement windows


On average we spend 80% of our time on refurbishing woodwork and preparing it for painting

Decayed window parts
will be replaced with Accoya/Tricoya wood

We scrape off old paint, remove decayed wood
and repair it with Accoya wood and high-tech
resinous fillers and adhesives.


For best results we spray paint restored windows

We use paint spraying for a number of reasons: it provides twice as thick coating and smooth, factory-like finish – no brush line marks.


We only use two paint bases: Zinser or Sherwin Williams as they protect windows for much longer than any other professional paint.

Thicker, more even coating,
means better all around protection

We also restore gables, conservatories, French doors and other woodwork

Every third client asks us to restore soffits, gables, wooden conservatories, doors, French doors and window shutters as part of a window restoration project

Tim & Debbie Howes, Barley

Many thanks for an excellent job on our cladding this morning. When you said that you would be spraying I was a little concerned but you did an excellent job of masking the doors, windows and brickwork and no signs of any over-spray. You left the site very clean and tidy. I have no reservations in highly recommending you to friends and neighbours.

Bryan Willmore

We have used Chameleon Decorators ever since they were recommended to us six years ago and have gone on to recommend them to as many people as we can. They are everything you could want in a decorating firm; punctual, polite, 100% reliable and most importantly, their work is second to none. When it comes to decorating, most people realise that prep work is the key to a good finish and Chameleon Decorators clearly know this. Whilst they prep meticulously, they work quickly and efficiently, leaving you with a job incredibly well done. I cannot praise them enough.
