What sets our patio doors apart in Stevenage.
Effortless Everyday Opening
One-handed glide on precision stainless rollers — the door of choice for a family that opens and closes it twice a day rather than twice a year.
Slim Aluminium or Warm uPVC
Choose aluminium for the slimmest sightline and colour-fast finish, or uPVC for a warmer touch and familiar frame profile. The mechanism is the same either way.
2- or 3-Pane Configuration
One sliding, one fixed for a 2-pane; one sliding, two fixed for a 3-pane run up to 5m. Bigger openings step up to a slim-frame slider.
PAS 24 Anti-Lift Locking
Hook-and-shootbolt multi-point locking, anti-lift bolts to stop leaves being levered off the track — the security a mid-range slider often skips.
Flush Threshold Available
Weathered sill as standard or a low-profile flush threshold for barrier-free access from tile to terrace.

- How long does patio doors installation take in Stevenage?
- Most Stevenage projects run to a two-to-eight week lead time from signed quote to install, depending on manufacture. Once on site, a typical patio doors install completes in one to five working days with full dust-sheet protection and clean-down.
- Do you handle conservation-area planning in Stevenage?
- 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 Stevenage projects that require them.
- What guarantee covers patio doors in Stevenage?
- Every patio doors installation in Stevenage 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 patio doors work near Stevenage?
- Yes — we can share recent patio doors case studies from across Hertfordshire, including projects in Old Stevenage, Great Ashby and neighbouring towns. Ask your surveyor at the on-site visit.
- What's the difference between a patio door and a sliding door?
- Both slide. "Patio door" is the traditional 2- or 3-pane inline slider up to around 5m — the practical everyday choice. "Sliding door" in our range refers to the premium slim-frame system with 20mm interlocks and panes up to 3m tall. Same principle, different scale and sightline.
- Aluminium or uPVC patio doors?
- Aluminium for the slimmest sightline, any-RAL finish and a 20-year colour guarantee. uPVC for a warmer feel, a warmer feel and a focused colour palette. Same rollers and locks either way.
- Can the slider be on either side?
- Yes — sliding leaf on the left or on the right, chosen at survey to suit the room layout. On a 3-pane run the slider is normally in the centre, opening either side.
