What sets our back doors apart in Welwyn Garden City.
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.

Common questions from Welwyn Garden City homeowners.
- Do you install back doors in Welwyn Garden City?
- Yes — South East Windows & Doors installs back doors across Welwyn Garden City (AL7, AL8) and the wider Hertfordshire area every week. Every project is surveyed, manufactured and installed by our own teams.
- How long does back doors installation take in Welwyn Garden City?
- Most Welwyn Garden City 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 Welwyn Garden City?
- The A1(M) and A41 corridor means Hertfordshire homeowners consistently benefit from acoustic-rated glazing. We spec triple-glazed and laminated options that transform a home's soundscape. We prepare planning-ready drawings with matched sightlines, glazing-bar depths and hardware for Welwyn Garden City projects that require them.
- What guarantee covers back doors in Welwyn Garden City?
- Every back doors installation in Welwyn Garden City 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 Welwyn Garden City?
- Yes — we can share recent back doors case studies from across Hertfordshire, including projects in Old Welwyn, Handside 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.
