Home Counties steel window services

From our Harlow base, we work with homeowners, architects and specifiers across the Home Counties and surrounding areas. Our experience includes projects in London and Surrey, covering residential and commercial buildings with Crittall windows for internal and external applications.

Whether you are replacing existing steel frames, planning a renovation or specifying windows for a new build, we can advise on suitable products, glazing, configurations and finishes. Our showroom lets you view Crittall products and discuss your specific requirements with our team.

Restoring period steel windows

For period and listed properties, restoration can be the right choice where original steel window frames remain suitable. Our restoration service can address issues including rust, corrosion and worn seals while helping retain the architectural style of existing windows.

Where replacement is needed, we can manufacture custom steel windows around your project’s requirements, including bespoke dimensions, profiles and finishes. This can provide peace of mind when working on sensitive heritage properties across London, Surrey and the wider Home Counties.

Bespoke Crittall window solutions

Our Crittall range includes external windows, internal windows, bespoke steel windows, W20TE and HomeLight systems. Slim steel profiles can maximise natural light, while modern glazing options can support insulation and energy efficiency. We also offer various colours and hardware finishes to suit different architectural styles and interior design schemes.

For projects requiring steel doors, our range includes Crittall options for residential and commercial settings, giving homeowners and specifiers flexibility over appearance, functionality and configurations.
