Designed around your opening

Think beyond the frame colour

Large glass panels can make the garden feel part of your living space even when the doors are closed. Because the panels travel along a track, you do not need a swing area inside the room or a folding stack on the patio.

For a kitchen extension in Colchester, a coastal home near Clacton or a replacement patio door in Brightlingsea, we start with how you want to use the space.

Before you choose

Aluminium sliding door FAQs

Straightforward answers to help you plan your project and compare quotations.

Ask our team
How much do aluminium sliding doors cost in Essex?

Your quotation depends on the door system, overall width and height, number of panels, glazing, colour and installation work. Send us approximate dimensions, your postcode and a photo of the opening so we can recommend suitable options and prepare a tailored price.

Should I choose sliding or bifold doors?

Sliding doors suit homeowners who prioritise large panes, garden views and an opening that does not need space for folding leaves. Bifolds are worth comparing when opening up more of the aperture is the priority. The best choice depends on your room, patio and preferred everyday access.

Can I have a two-panel or three-panel sliding door?

We can discuss two-panel, three-panel and larger layouts. Available tracks, opening directions and panel sizes depend on the chosen system. We will confirm how much of your opening is accessible with each proposed configuration.

Are aluminium sliding doors energy efficient?

Thermally broken aluminium frames and insulating glass help reduce heat transfer. Whole-door U-values vary with the system, dimensions and glass specification, so compare the performance of your actual proposed doors rather than a glass-only figure.

Can sliding doors have a low threshold?

Threshold options depend on the system and site conditions. We assess internal floor levels, the external patio, drainage and exposure before recommending a detail. A flush appearance needs to be planned alongside weather protection.

What colours and glazing can I choose?

Discuss black, anthracite grey, white and other available finishes with our team, including different internal and external colours where supported. We can also advise on privacy, solar control and glass options compatible with your chosen doors.

How long will manufacture and installation take?

Lead times depend on the manufacturer, finish, specification and installation schedule. We will confirm the current expected timescale with your quotation and agree the next steps after the survey.
