Spire Windows: PVCu windows, doors and conservatories made in Louth

Spire Windows is a family-run business that manufactures and installs premium-quality PVCu windows, doors and conservatories for homes in Lincolnshire and Yorkshire. The company states it was established in 1989 and describes itself as having more than 35 years of industry expertise, with all products made to measure at its own factory in Louth and a showroom next door.

Its frames are made from lead-free Liniar PVC, which the company says is extruded at what it describes as the largest UK mixing plant, based in Derbyshire. The multi-chambered construction is presented as more energy-efficient than traditional uPVC, and the frames are described as fully recyclable. Every frame is fitted with security features and covered by a 10-year guarantee.

Window styles and glazing options

The window range covers casement, flush sash, tilt and turn, sliding sash, bow and bay styles, plus aluminium windows and timber-look windows. Glazing choices include double and triple glazing, and decorative, obscure, safety and acoustic glass. Buyers can select frame colours and handles, and the range carries a Window Energy Rating.

Doors, conservatories and additional products

Door styles include composite, stable, French, bifold and flush doors, as well as aluminium doors, with options for frame colours, handles, decorative and obscure glass, and thresholds and cills. A Door Energy Rating is also listed.

For conservatories, Spire offers bespoke, Victorian, Edwardian and lean-to designs, along with conservatory roof upgrades using tiled or glass roofs. Porch options include frame colours, handles, roof vents, glazed roof panels, lanterns and roof lights, plus plumbing and electrics, planning permission and building regulations support. The company also lists orangeries and additional products such as decorative aluminium fencing, secondary glazing and air conditioning.

How a project runs

The process is set out in five stages. A design visit follows the initial enquiry, with a surveyor answering questions and providing a quote. A technical survey then takes final checks and measurements for manufacturing. Products are made to measure at the Louth factory, and installation is carried out by local fitters. Aftercare includes a follow-up call and the in-house guarantee.
