    Front door designs tailored to your home

    Our doors are a relatively inexpensive way to smarten the appearance of your home, make it more secure, and improve its thermal performance.

    Constructed in UPVC, aluminium, or a composite of both plus timber, they offer significant advantages over traditional all wood doors. They are fitted with secure, multipoint locking systems, they offer good thermal and noise insulation, and do not require refinishing.

    A vast array of styles makes it easy to personalise your door with decorative glazing, panelling designs and colour or textured finishes and many different fittings. We offer heritage front door patterns to suit period properties as well as the latest front door designs and styles to match your contemporary home.

    We also make it easy to transform the gateway to your garden with bi-fold doors, patio doors and French doors.

    Exceptional home security as standard

    New doors are one of the best ways to improve the security of your home.

    Manufactured in robust and durable materials, our range of doors includes frames that maximise overall assembly strength.

    They all incorporate industry-standard locking features that are both secure and long lasting. And we can include other security options such as toughened glazing, night-latches and security chains.

    Advanced double-glazed doors that will keep your home warm

    At least 15% of heat loss in the home is attributed to poorly fitting and poorly insulating doors. That amounts to chilly rooms and bigger bills which nobody wants.

    Changing your doors will not only eliminate draughts, but could improve your energy performance across the home. Our door sets have energy A+ ratings achieved with A+ rated door glazing as standard, argon gas cavity infills, edged spacer bars, separate chambered uPVC door profiles combined with airtight and weatherproof designs.

    Our aluminium doors are fitted with thermal break barriers, which resist thermal energy loss; our composite doors include single and double rebates, adding to their overall additional energy efficiency.
