Sash Windows in North London
Traditional box and spring-balance sash windows made-to-measure for North London homes - from Georgian townhouses in Islington to Victorian terraces in Muswell Hill and Edwardian semis in Palmers Green.
North London
Sash Windows you can trust
North London is sash window country. Whole streets in Islington, Hackney, Haringey and Barnet were built with vertical sliding sashes, and getting the proportions wrong on a replacement is instantly visible from the pavement. We specify sightlines, glazing bar widths and cill profiles that match what was originally there.
For heritage streets we supply engineered timber sashes with slim double-glazed units. For non-conservation homes uPVC sashes give the same look at a lower price with virtually no maintenance. We'll walk you through both options at the free survey.
Every sash is draught-proofed as standard - most customers see an immediate drop in heating bills and street noise.

FAQs
Sash Windows in North London - your questions answered
Can you fit sash windows in a conservation area?
Yes - we work regularly in Highgate, Muswell Hill, Canonbury and other Article 4 areas. We match sightlines, glazing bars and cill profiles to whatever the planning officer requires, and provide the drawings your listed building consent needs.
Timber or uPVC sash - which is better?
Timber gives the most authentic look and is often required in conservation areas. Modern engineered timber is stable and pre-finished for 8-10 years between repaints. uPVC sashes cost 30-40% less, need no maintenance, and modern slim-sightline profiles look convincing from the pavement.
How much do sash windows cost in North London?
A typical uPVC sash runs £950-£1,400 supplied and fitted. Timber sashes are £1,600-£2,400 each depending on size and finish. Whole-house quotes are usually 10-15% cheaper per window. Fixed written quote after the free survey.
Do you draught-proof old sash windows too?
Yes - if the joinery is sound we can strip, service, re-cord and brush-seal existing sashes. Often a better option in listed properties or where budget is tight. Ask at survey and we'll price both routes.
