Heritage Steel Doors in Highgate, London

Heritage Steel Doors designed around front doors that need to look right on a stucco terrace and secure a family home.
Highgate Village's Georgian core, the Heath-facing streets along Merton Lane and Fitzroy Park, and the substantial Victorian villas across N6 need matched sightlines and painted finishes. We install throughout with drawings prepared for Camden and Haringey planners.

What sets our heritage steel doors apart in Highgate.
Slim T-Bar Muntins
18mm powder-coated aluminium bars in a 3×3, 4×4 or 5×5 grid — the authentic Crittall sightline in a modern thermally-broken frame.
Thermally-Broken Profile
Polyamide thermal break inside the frame lets us hit 1.4 W/m²K on a fully glazed door — U-values the original steel Crittall could never approach.
Matte-Black Finish
Qualicoat Class 2 powder coat in matte anthracite or true jet black — colour-fast for 20 years, no rust, no peeling, no repainting.
Full-Height Side-Lights
Matched side lights and transoms transform a single door into a full-height glazed threshold, with the entire elevation reading as one continuous grid.
PAS 24 Concealed Multi-Point
Multi-point hook locking concealed within the slim frame — the security specification the aesthetic often skips.

Common questions from Highgate homeowners.
- Do you install heritage steel doors in Highgate?
- Yes — South East Windows & Doors installs heritage steel doors across Highgate (N6) and the wider London area every week. Every project is surveyed, manufactured and installed by our own teams.
- How long does heritage steel doors installation take in Highgate?
- Most Highgate projects run to a two-to-eight week lead time from signed quote to install, depending on manufacture. Once on site, a typical heritage steel doors install completes in one to five working days with full dust-sheet protection and clean-down.
- Do you handle conservation-area planning in Highgate?
- Working across London means understanding period detail, party-wall etiquette and permit parking as well as we understand glass. We schedule dust sheets, protection and clean-down like a good building firm should. We prepare planning-ready drawings with matched sightlines, glazing-bar depths and hardware for Highgate projects that require them.
- What guarantee covers heritage steel doors in Highgate?
- Every heritage steel doors installation in Highgate is covered by our insurance-backed 10-year guarantee — parts, labour and finish. Aftercare is direct with the installing team, not a call centre.
- Can I see recent heritage steel doors work near Highgate?
- Yes — we can share recent heritage steel doors case studies from across London, including projects in Highgate Village, Highgate West Hill and neighbouring towns. Ask your surveyor at the on-site visit.
- Is a steel-look door actually made of steel?
- No — ours are thermally-broken aluminium in a heritage profile with authentic 18mm T-bar muntins. Real Crittall steel doors rust, cold-bridge and can't meet modern U-value requirements. Aluminium gets you the same sightline without the drawbacks.
- Can I have real Crittall steel doors?
- We can supply and fit genuine Crittall Fendor steel systems where a listed building or specific brief demands them — but they have poorer U-values, and need repainting every 5–7 years. We advise honestly on the trade-off.
- How authentic does the aluminium look?
- At three paces you would not tell them apart from steel. The 18mm muntins, matte-black finish and grid proportions are drawn from measured Crittall drawings. Only if you tap the frame do you hear the difference.
