Arched Head Windows in Greenwich, London
Every arched head windows project we deliver in Greenwich starts with a senior surveyor on site — measuring, listening, and specifying to the character of West Greenwich, East Greenwich and the wider London area. Radius, segmental and Gothic-arched windows CNC-cut to your survey template.
Arched Head Windows designed around sash-heavy period stock, communal-window agreements and RBKC / Camden conservation planning.
Greenwich's Georgian and early-Victorian streets around the Royal Park, Blackheath's heath-side terraces and the Maritime conservation core each demand matched sightlines. We install throughout SE10 with planning-ready drawings.

What sets our arched head windows apart in Greenwich.
Radius, Segmental & Gothic
True radius (semi-circle), segmental (shallow arch), Tudor and Gothic (pointed) heads — CNC-cut to a survey template taken from the existing opening.
Template-Cut Precision
Every arched-head window is cut from a physical template surveyed on site — no assumptions, no gaps at the brickwork, no need to disturb the arch above.
Traceried & Divided
Arched heads can be divided by radial glazing bars, gothic tracery or curved astragal bars — matched to the period of the property.
Any Material
uPVC (fabricated on curved profile), aluminium (roll-formed) or heritage flush-casement — the material is chosen to suit the property, the head is cut the same way.
Modern Thermal Performance
Argon-filled A-rated glazing curved to the arch, warm-edge spacer bars and thermally-broken frames — U-values from 0.9 to 1.4 W/m²K on standard arched heads.
Chapels & School Conversions
The window we most often supply on chapel conversions, converted schools, Victorian bay fronts and stable-block conversions — properties where a rectangular replacement would look wrong.
What Greenwich homeowners tell us.
"Nine windows swapped across a Victorian first-floor flat. Zero mess, done in three days, and the acoustic laminate has genuinely changed how we sleep."
"The sliding sashes are indistinguishable from the originals — the conservation officer signed off first time. Immaculate site management too."
"Four quotes, one honest conversation. Their surveyor spent two hours explaining trade-offs — no other firm came close on either detail or clarity."
Common questions from Greenwich homeowners.

- How long does arched head windows installation take in Greenwich?
- Most Greenwich projects run to a two-to-eight week lead time from signed quote to install, depending on manufacture. Once on site, a typical arched head windows install completes in one to five working days with full dust-sheet protection and clean-down.
- Do you handle conservation-area planning in Greenwich?
- Working across London means understanding period detail, party-wall etiquette and permit parking as well as we understand glass. We schedule dust sheets, protection and clean-down like a good building firm should. We prepare planning-ready drawings with matched sightlines, glazing-bar depths and hardware for Greenwich projects that require them.
- What guarantee covers arched head windows in Greenwich?
- Every arched head windows installation in Greenwich 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 arched head windows work near Greenwich?
- Yes — we can share recent arched head windows case studies from across London, including projects in West Greenwich, East Greenwich and neighbouring towns. Ask your surveyor at the on-site visit.
- What thermal performance does arched head windows achieve in Greenwich?
- Energy-efficient arched head windows installed across Greenwich, London achieve whole-window U-values of 0.9–1.4 W/m²K, with the exact frame and glazing specification confirmed after survey.
- Do I need to remove the brickwork above the arch?
- No — we survey the internal arch profile with a template and cut the new frame to match. The masonry above stays completely undisturbed.
- Can the arched head be an opening light?
- Usually not — the curved head is a fixed light for structural reasons. Openings are placed in the rectangular section below the arch. On a large chapel-style window, we specify a radial opening light where head geometry permits.
- Can you match an existing Victorian bay-front arched window?
- Yes — we survey and template every arch individually, so even where original windows are inconsistent across a terrace we can match each one exactly. A single terrace of five bay-front houses might have five slightly different templates; we cut all five.
