Key Takeaways for Alresford Homes

  • Planning Handled: We manage all council applications for you.
  • Local Integrity: Honest advice and a No Pressure Promise.

Heritage Windows: The Timber Look, Without the Rot

For Alresford's period properties, maintaining the visual "sightlines" is critical. We install the market-leading Residence Collection (R9 & R7) and Deceuninck Flush Sash windows. These systems replicate 19th-century timber designs right down to the mechanical joints, but they never need painting.

Beyond the aesthetics, these windows are engineered for modern living. Unlike original timber which can warp and requires regular repainting, our timber-alternative ranges offer decades of low-maintenance performance. We offer a choice of mechanical joints for that authentic handcrafted look, alongside a vast palette of period colours and monkey-tail handles to complete the effect.

See It In Person: The Roseview 'Ultimate Rose'

It can be hard to believe that uPVC can look exactly like timber, which is why we invite you to see it for yourself. We display the stunning Roseview 'Ultimate Rose' sash window in our showroom.

Widely regarded as the most authentic uPVC sash window on the market, it features a slim mid-rail, mechanical joints, and a deep bottom rail that perfectly mimics traditional Victorian joinery. It is the ideal choice for Georgian properties in Alresford where authenticity is paramount.

Crucially, these windows also feature a "run-through" sash horn—where the decorative horn is an integral part of the structure rather than a glued-on extra. This provides a seamless, robust finish that stands up to close inspection. Combined with a tilt facility for easy cleaning and A-rated glass for thermal efficiency, the Ultimate Rose allows you to retain the historic charm of your home without sacrificing modern comfort.

Extensions & Tiled Conservatory Roofs

Many Alresford homeowners have older conservatories that are too hot in summer and freezing in winter. We can transform these spaces into true year-round extensions using our Tiled Conservatory Roof systems.

By replacing a glass or polycarbonate roof with a solid, insulated tiled roof (complete with Velux windows if desired), you gain a room that feels like a permanent part of your home. Internally, these extensions transform the feel of your property. The vaulted ceilings create a sense of light and space, while the high-performance insulation ensures the room stays warm even in the depths of winter.

We Handle The Paperwork: We understand that dealing with the Council can be daunting. KJM Group offers a comprehensive service that includes handling all necessary Planning Permission and Building Regulations applications on your behalf, ensuring your new extension is fully compliant and hassle-free.

Composite Doors: Matching Your Windows

Your front door sets the tone for your home. We offer a vast range of Composite Doors that combine solid cores for maximum security with stunning woodgrain finishes.

As you can see from the image, we can match a Residence 9 window with a high-security composite door in the same finish. Whether you choose a solid-core design in Chartwell Green, Painswick, or classic Black, you get a cohesive look that enhances your home's kerb appeal. All our doors come with multi-point locking systems as standard, keeping your home secure without compromising its traditional charm.

Aluminium: Slim, Strong & Modern

While Alresford is famous for its history, many homeowners in Four Marks and Medstead are adding modern extensions to the rear of their properties to create open-plan kitchen diners. For these spaces, Aluminium is the material of choice.

We install premium Aluminium Bi-Fold Doors and slimline windows that maximise the light flooding into your home. The incredible strength of aluminium allows for thinner frames and larger panes of glass, giving you uninterrupted views of your garden or the Hampshire countryside. Available in contemporary Anthracite Grey or classic Black, they provide a stunning contrast to traditional brickwork.

Alresford Home Improvement FAQs

In most cases, yes. Changing a translucent glass or polycarbonate roof to a solid tiled one is considered a 'change of material' and typically requires Planning Permission. It also requires Building Regulations approval to ensure the structure can support the weight and meets insulation standards. KJM Group handles this entire process for you, including submitting plans and dealing with the Council.

We install specific heritage ranges, such as the Residence Collection, which are designed to satisfy conservation officers by replicating traditional timber joinery. However, you should always check with the local planning authority first. We have extensive experience assisting clients with these applications.
