Everything we install in Marlow, Buckinghamshire.
What Marlow homeowners tell us.
A small selection of reviews from clients across Marlow and the surrounding Buckinghamshire area.
"Insulated garden studio, fully wired, plastered and finished — six weeks from survey to keys. It reads as an extension of the house, not a shed."
"A 7m bifold set across the back of our Chiltern barn conversion. Faultless install, faultless finish. The traffic door is a small detail that we now use every day."
"Their surveyor drove out twice before we'd even signed anything. That's the level of care we hoped for and rarely find."
Common questions from Marlow homeowners.
- Do you install windows and doors in Marlow?
- Yes — South East Windows & Doors covers Marlow (SL7) and the surrounding Buckinghamshire area weekly, including Marlow Bottom, Little Marlow, Bourne End. Every project is surveyed, manufactured and installed by our own teams.
- Which postcodes around Marlow do you cover?
- We cover SL7 across Marlow, together with neighbouring parts of Buckinghamshire. If your postcode isn't listed, call 020 3633 0405 — we almost certainly still cover you.
- What styles of window and door suit Marlow properties?
- River-facing homes benefit hugely from acoustic and thermal glazing upgrades; heritage frontages need matched sightlines. We do both in the same project. In practice that means we frequently specify heritage flush casements, slim aluminium sashes, painted composite front doors and aluminium bifolds for Marlow homes.
- How long does a typical installation take in Marlow?
- Most full-house window projects in Marlow 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 Marlow homes?
- Yes. Every Marlow enquiry gets a free on-site survey and a fixed written quote — no pressure selling, no "today only" discounts. Painted finishes, monkey-tail handles and deep-set reveals for planning consent.
- Are your uPVC windows suitable for Marlow homes?
- Our A-rated uPVC casement and flush-sash windows are the most popular choice across Marlow — energy-efficient, virtually maintenance-free and available in woodgrain and painted finishes to sit comfortably alongside neighbouring properties in Marlow Bottom and the wider Buckinghamshire area. Every frame is internally reinforced, fitted with Q-Lon seals and backed by a 10-year guarantee.
- Can you supply aluminium windows in Marlow in a specific RAL colour?
- Yes. Aluminium windows for Marlow 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 Marlow and Buckinghamshire.
- How wide can aluminium bifold doors go on a Marlow extension?
- We install aluminium bifolds up to 7m wide and 2.4m tall across Marlow — 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 Buckinghamshire winters.
- Do I need planning permission for a conservatory in Marlow?
- Most conservatories in Marlow 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 Buckinghamshire planning office on your behalf. Every conservatory we install is Building Regulations compliant.
- Do garden rooms in Marlow need planning permission?
- Insulated garden rooms in Marlow 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 Marlow 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 Marlow?
- Yes — we install across Marlow and Buckinghamshire 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.
