What Dulwich homeowners tell us.
A small selection of reviews from clients across Dulwich and the surrounding London area.
"Four quotes, one honest conversation. Their surveyor spent two hours explaining trade-offs — no other firm came close on either detail or clarity."
"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."
Dulwich, London · FAQs
Common questions from Dulwich homeowners.
- Do you install windows and doors in Dulwich?
- Yes — South East Windows & Doors covers Dulwich (SE21, SE22) and the surrounding London area weekly, including Dulwich Village, East Dulwich, West Dulwich. Every project is surveyed, manufactured and installed by our own teams.
- Which postcodes around Dulwich do you cover?
- We cover SE21, SE22 across Dulwich, together with neighbouring parts of London. If your postcode isn't listed, call 020 3633 0405 — we almost certainly still cover you.
- What styles of window and door suit Dulwich properties?
- The Dulwich Estate and Southwark's conservation officers scrutinise glazing bars, colours and door furniture in exacting detail. Our specifications are written to match. In practice that means we frequently specify heritage flush casements, slim aluminium sashes, painted composite front doors and aluminium bifolds for Dulwich homes.
- How long does a typical installation take in Dulwich?
- Most full-house window projects in Dulwich take 2–4 days on site once frames are manufactured. Bifolds, conservatories and garden rooms are quoted with a written programme so you know exactly what to expect.
- Do you provide fixed written quotes for Dulwich homes?
- Yes. Every Dulwich enquiry gets a free on-site survey and a fixed written quote — no pressure selling, no "today only" discounts. Timber-alike aluminium sashes with matched sightlines for SE21 frontages.
- Are your uPVC windows suitable for Dulwich homes?
- Our A-rated uPVC casement and flush-sash windows are the most popular choice across Dulwich — energy-efficient, virtually maintenance-free and available in woodgrain and painted finishes to sit comfortably alongside neighbouring properties in Dulwich Village and the wider London area. Every frame is internally reinforced, fitted with Q-Lon seals and backed by a 10-year guarantee.
- Can you supply aluminium windows in Dulwich in a specific RAL colour?
- Yes. Aluminium windows for Dulwich projects are available in any RAL colour, plus dual-finish (different colour inside and out) so you can match existing joinery or a bespoke scheme. Slim 55–75mm sightlines suit the larger openings we see on newer builds and contemporary extensions around Dulwich and London.
- How wide can aluminium bifold doors go on a Dulwich extension?
- We install aluminium bifolds up to 7m wide and 2.4m tall across Dulwich — typically in 3, 4, 5 or 6-pane configurations with an optional traffic door for everyday use. Every set is surveyed on site so structural openings, thresholds and lintels are checked before manufacture, and thermally-broken frames keep U-values low for London winters.
- Do I need planning permission for a conservatory in Dulwich?
- Most conservatories in Dulwich fall under permitted development, provided the extension stays within volume, height and boundary limits. If your property is listed, in a conservation area or has had previous extensions, we'll advise on a full planning submission and can liaise with the local London planning office on your behalf. Every conservatory we install is Building Regulations compliant.
- Do garden rooms in Dulwich need planning permission?
- Insulated garden rooms in Dulwich are usually built under permitted development — under 2.5m to the eaves when within 2m of a boundary, and no more than half your garden's footprint. We handle the design, base, insulation, wiring and finishes so your Dulwich garden studio is ready to use, and we'll flag any planning considerations before you commit.
- Can bifolds, conservatories or garden rooms be installed year-round in Dulwich?
- Yes — we install across Dulwich and London throughout the year. Frames and glass are manufactured off site, and installations are sequenced so your home stays weather-tight day-to-day. For garden rooms and conservatories we can pour bases in autumn and winter so you're ready to use the space by spring.
