What St Albans homeowners tell us.
A small selection of reviews from clients across St Albans 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."
"Punctual, quiet, tidy, honest. Three years on the front door still closes with that satisfying thud, and the paint finish hasn't moved."
"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 St Albans properties?
- St Albans District has extensive conservation-area coverage. Our heritage sashes and painted casements are prepared with planning-ready drawings and consistently accepted. In practice that means we frequently specify heritage flush casements, slim aluminium sashes, painted composite front doors and aluminium bifolds for St Albans homes.
- How long does a typical installation take in St Albans?
- Most full-house window projects in St Albans 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 St Albans homes?
- Yes. Every St Albans enquiry gets a free on-site survey and a fixed written quote — no pressure selling, no "today only" discounts. Aluminium bifolds for the typical AL1–AL4 rear extension — any RAL, concealed threshold.
- Are your uPVC windows suitable for St Albans homes?
- Our A-rated uPVC casement and flush-sash windows are the most popular choice across St Albans — energy-efficient, virtually maintenance-free and available in woodgrain and painted finishes to sit comfortably alongside neighbouring properties in Fishpool Street 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 St Albans in a specific RAL colour?
- Yes. Aluminium windows for St Albans 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 St Albans and Hertfordshire.
- How wide can aluminium bifold doors go on a St Albans extension?
- We install aluminium bifolds up to 7m wide and 2.4m tall across St Albans — 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 St Albans?
- Most conservatories in St Albans 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 St Albans need planning permission?
- Insulated garden rooms in St Albans 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 St Albans 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 St Albans?
- Yes — we install across St Albans 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.
