What sets our heritage steel doors apart in Dunstable.
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.

- Do you install heritage steel doors in Dunstable?
- Yes — South East Windows & Doors installs heritage steel doors across Dunstable (LU5, LU6) and the wider Bedfordshire area every week. Every project is surveyed, manufactured and installed by our own teams.
- How long does heritage steel doors installation take in Dunstable?
- Most Dunstable 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 Dunstable?
- New-build handovers frequently include basic-specification windows. A Bedfordshire homeowner upgrading to our A+ profile typically sees a measurable improvement in heating bills within a single winter. We prepare planning-ready drawings with matched sightlines, glazing-bar depths and hardware for Dunstable projects that require them.
- What guarantee covers heritage steel doors in Dunstable?
- Every heritage steel doors installation in Dunstable 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 Dunstable?
- Yes — we can share recent heritage steel doors case studies from across Bedfordshire, including projects in Houghton Regis, Kensworth 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.
