More than a new frame
Modern frames and glazing can help reduce heat loss and draughts compared with tired, poorly performing windows. We’ll explain the performance of your chosen specification.
Choose opening positions, handles and locking options around how you use each room. Our survey checks the practical details before your windows are made.
uPVC frames need no regular repainting. Simple cleaning and routine care of the moving parts help keep your windows looking good and working smoothly.
The finishing touches
From fresh white frames to grey, softer heritage shades and woodgrain effects, the finish makes a real difference. Compare physical samples before making your final choice.
Colours, glazing and hardware availability vary by system. We’ll confirm everything in your quotation.

It’s easier to choose when you can see the finish and try a window for yourself. Visit our Brightlingsea showroom to compare the displays, look at samples and talk through your ideas without pressure.
