📌 Our Core Services

Windows & Doors

From ultra-secure Composite Front Doors to A-rated uPVC, Aluminium, and premium Residence 9 timber-alternative windows, we secure and insulate your home.

Conservatories & Extensions

We build beautiful new living spaces using traditional methods, solid roof refurbishments, and the revolutionary, fast-build hup! extension system.

1. Premium Windows: Thermal Efficiency Meets Style

Windows are the eyes of your home, but they are also your primary defence against the great British weather. Our home renovation services focus heavily on upgrading properties with high-performance double and triple glazing that actively lowers heating bills and boosts EPC ratings.

🪟 Modern Materials
  • uPVC: The ultimate cost-effective, low-maintenance choice.
  • Aluminium: Ultra-slim frames for maximum glass and a sleek, contemporary look.
  • Timber & Residence 9: Authentic, heritage styling perfect for conservation areas.
📐 Versatile Styles
  • Casement: The classic, versatile outward-opening window.
  • Flush Casement: The sash sits perfectly flush with the frame for clean lines.
  • Sliding Sash: Traditional vertical opening mechanisms for period properties.

2. Doors: Ultimate Security & Kerb Appeal

A new door is one of the fastest and most impactful home renovations you can undertake. It is the focal point of your property’s exterior and the first line of defence against intruders.

  • Composite & Aluminium Front Doors: Combining traditional looks with the high-tech performance of modern materials, our designer doors offer unmatched security, weather resistance, and stunning kerb appeal.
  • Bi-Fold Doors: Perfect for completely opening up the rear of your home to the garden, creating a seamless transition between indoor and outdoor living.
  • French & Patio Doors: Elegant, classic solutions for allowing maximum natural light into your kitchen or living room.

3. Conservatories & hup! Extensions

When you need more space but want to avoid the massive disruption and spiralling costs of a traditional brick-and-block build, our structural home renovation services provide the perfect solution.

Alongside beautiful bespoke conservatories and elegant orangeries, we are proud installers of the hup! extension system. This revolutionary, lightweight building system uses highly insulated, prefabricated wall panels. It can be built in a fraction of the time of a traditional extension, is fully Building Regulation compliant, and offers outstanding, year-round thermal performance.

4. Solid Conservatory Roof Refurbishments

If you already have a conservatory but find it unusable because it is too hot in the summer and freezing in the winter, you don’t need to tear it down. We specialise in retrofitting older conservatories with highly insulated, lightweight solid tiled roofs.

This single home renovation transforms a neglected glass box into a comfortable, ambient room that feels like a true extension of your home, adding massive functional value to your property.

5. Trusted by Thousands: Our Accreditations

When you are investing heavily in your home, peace of mind is just as important as the quality of the products. We are incredibly proud of the reputation we have built across Hampshire over the decades. In fact, KJM Group recently topped Which?, Google, and Checkatrade with near-perfect scores across the board.

We do not offer temporary fixes like “de-fogging” existing units. However, we do offer comprehensive replacement services. We can replace the blown sealed glass units entirely, restoring the window’s thermal efficiency without needing to replace the whole frame.

The hup! system is a modern alternative to traditional brick extensions. It uses highly insulated, prefabricated wall panels that clip together rapidly on-site. It is incredibly thermally efficient, fully Building Regulation compliant, and can be built much faster than a standard extension, reducing disruption to your home.

Absolutely not. KJM Group operates a strict no-pressure policy. We believe our high-quality products, competitive transparent pricing, and extensive local reputation speak for themselves. We provide the expert advice and the quote, and then leave you in peace to make your decision.
