- Are your uPVC windows suitable for Irthlingborough homes?

Every frame is internally reinforced, fitted with Q-Lon seals and backed by a 10-year guarantee.
- Can you supply aluminium windows in Irthlingborough in a specific RAL colour?
- Yes. Aluminium windows for Irthlingborough 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 Irthlingborough and Northamptonshire.
- How wide can aluminium bifold doors go on a Irthlingborough extension?
- We install aluminium bifolds up to 7m wide and 2.4m tall across Irthlingborough — 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 Northamptonshire winters.
- Do I need planning permission for a conservatory in Irthlingborough?
- Most conservatories in Irthlingborough 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 Northamptonshire planning office on your behalf. Every conservatory we install is Building Regulations compliant.
- Do garden rooms in Irthlingborough need planning permission?
- Insulated garden rooms in Irthlingborough 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 Irthlingborough 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 Irthlingborough?
- Yes — we install across Irthlingborough and Northamptonshire 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.
