Aluminium windows — slim frames, more glass
Aluminium suits rear extensions, open-plan kitchen renovations, contemporary homes and higher-value refurbishments in Windsor. Slim sightlines let in more daylight, the frames are strong and weather-resistant, and the finish range runs from anthracite grey to any RAL colour. Maintenance is minimal and the lifespan is long.
uPVC windows — efficient and good value
For full-house replacements where value matters, modern uPVC gives strong energy ratings, secure multi-point locking and clean styling, including flush casement and sliding sash options that suit Windsor’s period streets.
Energy-efficient replacement windows in Windsor
Old or poorly fitted windows cause higher bills, cold spots, draughts and condensation. A-rated double glazing — or triple where it is genuinely worth it — improves insulation and cuts traffic noise, useful on the busier roads around the town centre and the A308. Most homeowners notice the difference in warmth straight away.
Windsor conservation areas and Article 4 directions
Much of central Windsor, Eton and parts of Old Windsor sit within conservation areas, and some streets are covered by an Article 4 direction that removes permitted development rights — meaning you may need planning permission to change windows, even like-for-like. In those cases the replacements usually need to match the original in material, sightline, opening style and glazing bar layout. We regularly fit heritage-appropriate flush casement and sliding sash windows in these areas and can advise on what the Royal Borough is likely to accept before you apply.
Two related guides: modern window performance in historic Windsor streets and Windsor’s planning rules for extensions.
Building regulations apply to replacement windows whether or not planning permission is needed. We register every installation for building regulations and provide the compliance certificate on completion.

How much do new windows cost in Windsor?
Every quote is fixed after a free survey. As a guide, individual windows start from around £500 (uPVC) and £950 (aluminium), supplied and fitted. A full house of uPVC windows in a typical Windsor home runs roughly £6,000–£12,000, and aluminium £11,000–£20,000, depending on size, style and glazing specification. 0% and low-rate finance options are available on larger projects, subject to status. See our full window cost guide for a detailed breakdown.
The Windsor homes we work on
Windsor’s housing is a real mix, and the right window depends on the street. Close to the town centre and the Castle you get Georgian and early-Victorian townhouses and terraces, many with original timber sash windows and tight sightline requirements. Around Clewer, Spital and Alma Road there are Victorian and Edwardian bay-fronted terraces. Dedworth and parts of Clewer are largely 1930s semis and post-war housing, and there are modern estates and infill developments throughout.
On period property we fit slim-sightline aluminium or timber-alternative sliding sash and flush casement windows that keep the proportions right. On 1930s and post-war homes we usually replace like-for-like in uPVC or aluminium with a better thermal spec. For rear extensions and garden rooms we fit aluminium bifold and sliding doors.
