A small selection of reviews from clients across Hitchin and the surrounding Hertfordshire area.
"Slim aluminium sashes in anthracite grey — exactly the balance of period feel and modern lines we wanted. Conservation area approved."

"A proper trade. Every promise kept — from the timescale to the finish. We've since recommended them to three neighbours."

- What styles of window and door suit Hitchin properties?
- North Herts Council's Hitchin conservation area protects a fine market-town core. Our heritage sashes and painted casements are prepared for that consent process as standard. In practice that means we frequently specify heritage flush casements, slim aluminium sashes, painted composite front doors and aluminium bifolds for Hitchin homes.
- How long does a typical installation take in Hitchin?
- Most full-house window projects in Hitchin 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 Hitchin homes?
- Yes. Every Hitchin enquiry gets a free on-site survey and a fixed written quote — no pressure selling, no "today only" discounts. Timber-alike casements for the older village properties.
- Are your uPVC windows suitable for Hitchin homes?
- Our A-rated uPVC casement and flush-sash windows are the most popular choice across Hitchin — energy-efficient, virtually maintenance-free and available in woodgrain and painted finishes to sit comfortably alongside neighbouring properties in Ickleford and the wider Hertfordshire area. Every frame is internally reinforced, fitted with Q-Lon seals and backed by a 10-year guarantee.
- Can you supply aluminium windows in Hitchin in a specific RAL colour?
- Yes. Aluminium windows for Hitchin 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 Hitchin and Hertfordshire.
- How wide can aluminium bifold doors go on a Hitchin extension?
- We install aluminium bifolds up to 7m wide and 2.4m tall across Hitchin — 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 Hertfordshire winters.
- Do I need planning permission for a conservatory in Hitchin?
- Most conservatories in Hitchin 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 Hertfordshire planning office on your behalf. Every conservatory we install is Building Regulations compliant.
- Do garden rooms in Hitchin need planning permission?
- Insulated garden rooms in Hitchin 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 Hitchin 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 Hitchin?
- Yes — we install across Hitchin and Hertfordshire 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.
