What sets our french doors apart in Harpenden.
Rebated Meeting Stile
The master and slave leaves close on a properly rebated overlap — not the flat butt-joint of conventional systems — sealing against draught, driving rain and forced entry.
Master & Slave Locking
Multi-point hook lock on the master leaf, shootbolt tops-and-bottoms on the slave. Slave sits fixed for daily use; both open together for parties and moving furniture.
Fully Glazed by Default
Single large pane per leaf, or Georgian-bar 15-light doors for period elevations. Any glass — obscured, laminated, acoustic — available.
Available in Three Materials
Painted timber-look composite for period cottages, thermally-broken aluminium for contemporary rear extensions, or A-rated uPVC for straightforward replacement.
Side-Lights & Fanlights
Add narrow side lights and an arched fanlight above and the pair reads as a full glazed threshold — the standard for garden-facing rooms.
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 french doors in Harpenden?
- Yes — South East Windows & Doors installs french 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 french 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 french 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 french doors in Harpenden?
- Every french 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 french doors work near Harpenden?
- Yes — we can share recent french doors case studies from across Hertfordshire, including projects in Harpenden Common, Southdown and neighbouring towns. Ask your surveyor at the on-site visit.
- French doors or bifold doors?
- French doors are the traditional answer for openings up to about 1.8m — a pair of full-glazed leaves that swing open on a rebated stile. Beyond that width, bifolds or sliders take over. French doors also look right on period elevations where bifolds don't.
- Do both leaves open?
- Yes. The slave leaf is held closed by shootbolts top and bottom; release them and it swings open for parties, garden furniture and moving-in day. The master leaf has the multi-point lock and everyday handle.
- Are they secure with two leaves?
- Yes — the rebated meeting stile plus master multi-point plus slave shootbolts are collectively more secure than a single door. Every French door we fit is PAS 24 accredited.
