What sets our back doors apart in Harpenden.
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 Harpenden homeowners tell us.
"Slim aluminium sashes in anthracite grey — exactly the balance of period feel and modern lines we wanted. Conservation area approved."
"Punctual, quiet, tidy, honest. Three years on the front door still closes with that satisfying thud, and the paint finish hasn't moved."
"A proper trade. Every promise kept — from the timescale to the finish. We've since recommended them to three neighbours."
Common questions from Harpenden homeowners.
- Do you install back doors in Harpenden?
- Yes — South East Windows & Doors installs back doors across Harpenden (AL5) 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 Harpenden?
- Most Harpenden 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 Harpenden?
- 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 Harpenden projects that require them.
- What guarantee covers back doors in Harpenden?
- Every back doors installation in Harpenden 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 Harpenden?
- Yes — we can share recent back doors case studies from across Hertfordshire, including projects in Harpenden Common, Southdown 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.
