Aluminium Windows in Lewes
12 March 2017 · Updated 12 August 2026In short: we supply and install aluminium windows in Lewes and the surrounding villages, working from our workshop at Piltdown, about twenty minutes north. Aluminium suits Lewes housing stock well, because slim frames let you keep a large glass area in the modest window openings common in older town properties.
Why aluminium in a town like Lewes?
Lewes has a lot of period and character property, much of it with window openings that are not especially large. That is exactly the situation where frame width matters: the narrower the frame, the more of the opening stays as glass, and the lighter the room feels.
Aluminium is a structural metal, so a slim section can carry a large pane without the bulk a plastic frame needs. In a small opening that difference is the difference between a window that feels generous and one that feels boxed in.
What if my property is in a conservation area?
Parts of Lewes are within conservation areas and some properties are listed, and both can restrict what you may fit, particularly on elevations visible from the street. Rules vary by property and by elevation, so the reliable answer comes from Lewes District Council rather than from us.
What we can do is help you specify something appropriate once you know the constraint. Slim sightlines, a considered colour and the right opening style all help a modern window sit comfortably in an older building. Ask the council first, then talk to us about specification, and not the other way round.
Which window styles work best?
It depends on the opening and the age of the property:
- Casement windows are the most common choice and suit the majority of openings.
- Flush sash windows sit level with the frame when closed, which reads as more traditional and often suits period property better.
- Tilt and turn windows are worth considering on upper floors, where cleaning the outside of the glass from inside is genuinely useful.
- Sliding sash windows suit properties where the original windows were vertical sliders and the proportion matters.
What about colour?
Aluminium is powder coated, so the colour range is wide and you can have one colour outside and another inside. That is useful in an older property where a heritage-appropriate colour suits the street elevation while something lighter suits the room. See our colour options and finishes.
Do you cover the villages around Lewes?
Yes. We work throughout East and West Sussex and Lewes is comfortably within our normal area, along with the surrounding villages and the coast towards Newhaven and Seaford. If you are unsure whether we reach you, ask.
Common questions
Can I put aluminium windows in a listed building in Lewes?
That is a decision for the local authority and depends on the building. Listed building consent is a separate process from planning permission. Speak to Lewes District Council before committing to a specification.
Are aluminium windows suitable for older properties?
Often yes, particularly slim or flush sash profiles, which sit more sympathetically in an older opening than a bulky frame. The determining factors are usually the conservation constraint and the proportion of the original opening rather than the material itself.
How long does an installation take?
It depends on how many windows and what access is like. We give you a realistic timescale after surveying rather than a general figure, because a single window and a full house are very different jobs.
