Before you choose
Both can work well. uPVC is often the more economical starting point, with a wide choice of traditional styles. Aluminium is worth comparing if you prefer slimmer-looking frames, larger glazed areas or a contemporary finish. We’ll help you compare the actual systems, glazing and fitted costs for your home.
The guide figures on this page give an initial budgeting range. Your final price depends on sizes, the number of opening sections, material, colour, glass and fitting requirements. We provide a written quotation for your chosen specification, including the applicable VAT and installation details.
Many ranges offer dual-colour options, including a coloured exterior with a white interior. The combinations and finishes available depend on the window system. Ask to see samples before choosing.
We can discuss double glazing and, where supported by your chosen system, triple glazing. The right choice depends on the complete window specification, your home and your priorities. Ask us to compare whole-window thermal performance rather than glass alone.
Yes. Visit our showroom at 18 High Street, Brightlingsea, Colchester, Essex, CO7 0AE. Book an appointment so we can talk through your plans, show you the window displays and compare finish samples.
The fitting schedule depends on the number of windows, access and the work involved. Once we have assessed your project, we’ll explain the expected installation time and how we will organise the work.
