Back Doors in Bromley and Dartford, to Maidstone and Sevenoaks

Replacing back doors can often get overlooked as they’re not as visible as front doors. However, maintaining its performance is just as important as the front of your property. The rear of your home is often seen as a weak point for potential burglars, so ensuring it can withstand substantial force is vital. All of our doors are constructed with high-quality materials that are chosen for their exceptional durability and strength. Their innovative designs also mean they provide excellent thermal capabilities.

Our high-performing back door solutions are available in uPVC, aluminium, or composite materials, and a range of versatile styles, colours and designs. With such a variety of combinations, your new back door will perfectly complement your home. Back door styles that incorporate large panes of glass, such as bi-folds, sliding patio doors and French doors, will let the natural light flood into your home, while the reinforced glass means it won’t compromise on the security capacity.

    Composite back door styles and designs

    Our composite back doors provide exceptional performances as they are manufactured using several materials, rather than just one. Our pioneering composite door fabrications incorporate hardwood panes of timber, modern uPVC elements and a foam core in the door panel. The dense door panel is able to stay intact from even the toughest forces and is highly weather-resistant. The reinforced frames are efficiently insulating as they are bonded together with lamination layers and uPVC edged banding, meaning they’re draught-free. The composite material is finished in an outer GRP skin that is resilient to scratches and dents and eliminates the occurrences of cracking, warping or fading. This modern manufacturing process also avoids any upkeep to ensure they continue to perform efficiently for their lifetime, which lasts at least 30 years.

    We can easily create exclusive composite back door styles. With 150 RAL colours and a plethora of smooth and authentic woodgrain finishes, they can perfectly suit both old and new properties alike. For a distinctive design, we can include bespoke glazing and elegant hardware.

    Our composite back doors are fitted with Yale locks as standard. Yale is the leading supplier of door locking systems, so you can have peace of mind that your home has the best protection possible.
