Welcome to the Steel Window Company Website

The Steel Window Company is a Trading style of Fabco Sanctuary Limited, and we are leading manufacturers and restorers of steel windows and doors within the UK. Our restoration and new window manufacturing service are designed to be sympathetic to the requirements of both the building and our client.

Our steel windows and doors are manufactured using only the highest quality materials and manufacturing techniques, we believe they are second to none in terms of build quality and components when compared alongside other Steel fenestration. And more importantly we can maintain this quality at a competitive price.

We provide free onsite surveys and quotations on request, where we can bring samples of our windows for you to view and compare, or please feel free to call in and visit our showroom.

Our hand-crafted wooden windows and subframes are available in all types of hard or softwoods. We have a number of stock designs to choose from or we can match your existing frame profiles from initial survey.

Our craftsmen specialise in the sympathetic conservation and repair of existing metal window casements in order that they can be enjoyed by future generations.



Window and door ironmongery can be selected from our wide range of furniture, or alternatively they can be custom made by either casting or by our blacksmith to match any older originals you may have.


Our windows can be glazed with a range of modern or historical glasses that are avaliable in leaded lights (lattice windows), single glazing or double glazed units to comply with Building Regulations Part L where required.

The comprehensive experience we have gained from working with our clients over the years enables us to offer the highest quality workmanship combined with an unequalled level of service. We are more than happy to give free impartial advice and have helped many Authorities, Architects, Surveyors, and Contractors with their more difficult projects.

Clients include English Heritage, The National Trust, Welsh Heritage (CADW), Historic Scotland, The Church of England, town councils, and private individuals.
