Company Overview

Steel Window Service, a member of the Steel Window Association, has been in the industry since 1951 and is recognised as a leading company specialising in the design, supply and fix, servicing, repair and replacement of steel windows.

Experienced in carrying out contracts of all sizes in the commercial and domestic sector, we offer a full advisory and project management service directly to the public local authorities, property management companies, housing associations, architects and main contractor builders.

With a comprehensive quality assurance system in place, the directors have addressed health and safety issues and our teams of directly employed fixers are all experienced skilled workers who have been with the company for many years.


Our Windows

The modern steel window is galvanised for positive rust-proofing, and with a durable and attractive polyester powder coating, provides a long-lasting product with low-cost maintenance.

The large range of SMW, SMW+, W20, W30, W40 and fire rated steel window and door products we offer, allow versatility of design and enables us to offer replica replacement windows of an exact match in historic and listed buildings, as well as offering far greater levels of thermal and acoustic insulation to meet the ever-increasing demands of the UK Building Regulations.

The introduction of double and triple glazing units to our ranges, up to 28mm thick, has not affected the slender elegant sightlines that are synonymous with mild steel windows, as well as the well-proven values of inherent strength, fire resistance, maximum security and resistance to vandalism.

As an alternative to sometimes costly replacement, we also offer a complete overhaul, upgrade and repair service. Steel windows and doors can be made entirely operable and draught free by servicing - a process of oiling, easing and adjusting the opening frames, removing excess paint and straightening if necessary, to ensure correct closure. Security locks and trickle ventilators can be supplied and fixed. Full draught-proofing services are offered. Fittings can be tightened, re-fixed or replaced to match where necessary and panes re-glazed.

Should the buildings in your care require repair or replacement work one of our experienced estimator surveyors would be glad to meet you on-site to discuss particular requirements and offer technical advice.



Our expert team using CAD systems are able to offer a full technical service ensuring the best possible design solution for the discerning client.

We produce full working drawings to provide an 'as built' view of proposed windows as well as full-size sectional details for your approval prior to manufacture on all contracts.


Project Management

Individual projects are assigned a personal project manager to handle the assignment from conception to completion. Close site supervision ensures successful installation by our directly employed teams of experienced CSCS certified operatives.
