Back Doors in Marylebone, London
Every back doors project we deliver in Marylebone starts with a senior surveyor on site — measuring, listening, and specifying to the character of Marylebone Village, Portman Estate and the wider London area. Secure, insulated back doors in uPVC, aluminium and composite.
Back Doors designed around front doors that need to look right on a stucco terrace and secure a family home.
Marylebone's Georgian townhouses off the High Street and the Portland-stone mansion blocks along Marylebone Road need timber-alike sightlines. We install throughout W1 and NW1 with drawings prepared for Westminster planners and managing agents.

What sets our back doors apart in Marylebone.
Half-Glazed by Default
Obscured privacy glass in the upper half lets light into a utility or hallway without exposing a full glazed door to the garden. Fully glazed and solid-panel variants also available.
PAS 24 Multi-Point Locking
Same locking specification as the front door — multi-point hook, 3-star anti-snap cylinder, laminated inner glazing. Back doors are the entry point insurers ask about.
Low-Threshold Option
Standard 45mm weathered cill or Part M compliant 15mm low-threshold aluminium sill for wheelchair, pushchair and step-free access to the garden.
Cat-Flap Ready
We machine cat-flap apertures at manufacture — clean, sealed and weather-tight — rather than the retrofit hole a joiner cuts on-site.
Colour-Fast Finish
Chartwell Green, Painswick, Anthracite, Cream, Rosewood and 15+ more stocked as deep-grain foils or spray-applied RAL finishes.
What Marylebone homeowners tell us.
"Four quotes, one honest conversation. Their surveyor spent two hours explaining trade-offs — no other firm came close on either detail or clarity."
"Nine windows swapped across a Victorian first-floor flat. Zero mess, done in three days, and the acoustic laminate has genuinely changed how we sleep."
"The sliding sashes are indistinguishable from the originals — the conservation officer signed off first time. Immaculate site management too."
Common questions from Marylebone homeowners.
- Do you install back doors in Marylebone?
- Yes — South East Windows & Doors installs back doors across Marylebone (NW1, W1) and the wider London area every week. Every project is surveyed, manufactured and installed by our own teams.
- How long does back doors installation take in Marylebone?
- Most Marylebone projects run to a two-to-eight week lead time from signed quote to install, depending on manufacture. Once on site, a typical back doors install completes in one to five working days with full dust-sheet protection and clean-down.
- Do you handle conservation-area planning in Marylebone?
- 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 Marylebone projects that require them.
- What guarantee covers back doors in Marylebone?
- Every back doors installation in Marylebone 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 back doors work near Marylebone?
- Yes — we can share recent back doors case studies from across London, including projects in Marylebone Village, Portman Estate and neighbouring towns. Ask your surveyor at the on-site visit.
- Do back doors need the same security as front doors?
- Yes — most insurers require the same PAS 24 multi-point locking and 3-star anti-snap cylinder on every external door. A back door onto a fenced-off garden is not lower risk; it's often higher because it's less overlooked.
- What material for a back door?
- uPVC for hard-wearing everyday use and value. Composite where the back door is on view from the garden and needs to match the front. Aluminium where the door reads through to a contemporary rear elevation. All three carry identical security.
- Can I have a cat-flap?
- Yes — machined into the door at manufacture, so it's clean, sealed, insulated and weather-tight. Petsafe, SureFlap and Cat-Mate are the three brands we fit as standard.
