Common questions from Stevenage homeowners.
- Do you install upvc doors in Stevenage?
- Yes — South East Windows & Doors installs upvc doors across Stevenage (SG1, SG2) and the wider Hertfordshire area every week. Every project is surveyed, manufactured and installed by our own teams.
- How long does upvc 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 upvc 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 upvc doors in Stevenage?
- Every upvc 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 upvc doors work near Stevenage?
- Yes — we can share recent upvc doors case studies from across Hertfordshire, including projects in Old Stevenage, Great Ashby and neighbouring towns. Ask your surveyor at the on-site visit.
- How secure are modern uPVC doors?
- Ours are tested to PAS 24:2016 with 3-star anti-snap cylinders, multi-point hook locking and laminated inner glazing. In independent forced-entry testing they resist attack for over 5 minutes — well beyond the 3-minute threshold most burglars abandon.
- Are uPVC doors as warm as composite?
- Very close — both hit 1.4 W/m²K on standard A-rated glazing. The main difference is aesthetic: composite mimics timber, while uPVC gives you a cleaner, more contemporary look.
- Can I have a uPVC door in a heritage colour?
- Yes. Painswick, Chartwell Green, Cream, Anthracite Grey and Rosewood are stocked as deep-grain foils. Any RAL can be sprayed to order for around 10% more.
