What Chesham homeowners tell us.
A small selection of reviews from clients across Chesham and the surrounding Buckinghamshire area.
"The orangery has become the heart of the house. Warm in January, cool in July. Every trade on site was courteous and clean."
"We spoke with three installers. They were by a mile the most professional. The composite front door still looks showroom two winters on."
"Heritage flush casements across the whole cottage. From the road you'd swear they were painted timber — but with modern thermal performance."
Common questions from Chesham homeowners.
- Do you install windows and doors in Chesham?
- Yes — South East Windows & Doors covers Chesham (HP5) and the surrounding Buckinghamshire area weekly, including Waterside, Botley, Ashley Green. Every project is surveyed, manufactured and installed by our own teams.
- Which postcodes around Chesham do you cover?
- We cover HP5 across Chesham, 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 Chesham properties?
- Chiltern District planners scrutinise reveals and hardware in the AONB. Our heritage casements and painted finishes are prepared for that consent process. In practice that means we frequently specify heritage flush casements, slim aluminium sashes, painted composite front doors and aluminium bifolds for Chesham homes.
- How long does a typical installation take in Chesham?
- Most full-house window projects in Chesham 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 Chesham homes?
- Yes. Every Chesham enquiry gets a free on-site survey and a fixed written quote — no pressure selling, no "today only" discounts. Aluminium bifolds for the typical Chesham rear extension.
- Are your uPVC windows suitable for Chesham homes?
- Our A-rated uPVC casement and flush-sash windows are the most popular choice across Chesham — energy-efficient, virtually maintenance-free and available in woodgrain and painted finishes to sit comfortably alongside neighbouring properties in Waterside 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 Chesham in a specific RAL colour?
- Yes. Aluminium windows for Chesham 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 Chesham and Buckinghamshire.
- How wide can aluminium bifold doors go on a Chesham extension?
- We install aluminium bifolds up to 7m wide and 2.4m tall across Chesham — 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 Chesham?
- Most conservatories in Chesham 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 Chesham need planning permission?
- Insulated garden rooms in Chesham 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 Chesham 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 Chesham?
- Yes — we install across Chesham 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.
