How much do steel windows and doors cost?
We specialise in beautifully crafted, made-to-measure steel windows and doors, combining precision engineering with high-quality materials. Our designs are created to stand the test of time, making them ideal for projects where exceptional quality, long-term performance and design integrity really matter. You can also expect excellent thermal performance and elegantly slim sightlines.
As a general guide, our pricing is as follows (goods only):
• Single external doors: from £2,500–£3,500+
• Double doors: from £4,000–£6,000+
• Larger installations (e.g. doors with screens): from £8,000–£10,000+
Our optional services, such as site survey, delivery and installation, are priced individually depending on factors like location and the scope of your project. We’ll be happy to provide a detailed estimate.
Every project is bespoke, so the more details you can share (such as plans, elevations or approximate sizes) the more accurate we can be with your initial quotation.
What sets Fabco frames apart?
Fabco frames use hot-rolled steel for production, produced in Switzerland for uncompromising quality, and shipped directly to our factory in West Sussex where are in house team fabricate the frames.
Why choose steel glazing or aluminium?
Steel is much stronger than aluminium, enabling our products to maintain a slimmer profile whilst also spanning further per leaf. For example, our external doors can be scaled up to 2500mm (H), whereas an aluminium frame that is four times the profile size is limited to 2400mm (H). Watch out for ‘steel-like’ products, they are still aluminium!
Our frames also use authentic steel glazing bars welded into the frame during fabrication, whereas other like-for-like products can consist of 10-12mm plastic glazing bars adhered to the glass which fail over time due to fluctuations in conditions.
Do you work with heritage sites?
Fabco can and has produced steel glazing for heritage and listed building sites, with some beautiful examples on our social media. We can offer single glazing for these projects in line with building control requirements.
Are Fabco’s steel doors fire-rated?
Fabco’s W40 system carries an FD30 fire integrity rating, assessed independently by Warringtonfire. That covers doors and screens within the assessed Ottostumm configuration, one side only. It does not apply to W20 or W20+ systems. Please speak to your building control officer for further information.
Double or triple glazing?
Due to the slim nature of our frames steel profile, Fabco are able to fit an 18mm double glazed unit into the frames. Triple glazing is unfortunately too chunky for our product, and requires a larger aluminium profile. We use an incredibly high performing double glazed unit, filled with Krypton gas which performs far greater than the industry standard Argon gas
Can you offer different locking options?
We offer a standard 5-lever locking system with our external doors, with the option to upgrade to our multipoint locking for extra security. Multipoint is required if the door(s) is a final point of exit. We can also offer PAS24 security certified doors, subject to design.
What makes Fabco steel doors different?
Our frames are one of the slimmest and thermally efficient on the market, allowing us to maximise glazing areas to maintain unobstructed sightlines, bringing as much natural light into your property as possible.
What sightlines does Fabco’s W20 system achieve?
Fabco’s W20 system achieves 10mm sightlines with a 32mm face width. That’s made possible by hot-rolled W20 steel sections and fully TIG-welded construction. Glazing bars are welded into the frame structure, not clipped or glued on. The result is a genuine structural sightline of 10mm, not a decorative approximation.
