    Our composite back doors are fitted with the highly reputable Yale smart locks

    Our composite doors are available in two designs: entrance front doors and heritage doors.

    Regardless of design, all our composite doors are fabricated using various materials, including hardwood timber and uPVC, and insulating reinforced frames that are bonded together with laminated layers. Combined together, this creates a sturdy door with a dense core that boasts a premium quality that one singular material simply cannot achieve. The outer GRP skin eliminates dents and scratches and provides you with at least 30 years of being maintenance-free. To prolong this life expectancy, we would recommend maintaining composite doors with warm soapy water and a clean sponge to keep your composite door looking as good as new.

    They are then finished with the highly reputable Yale multi-point locking systems as standard. These locking mechanisms are known for being the best locking mechanisms available on the market, so you can be sure that their advanced security systems will keep the rear of your home safe. Yale smart locks are totally keyless and let you open your door in a variety of different ways, so there is no more hiding spare keys under doormats or plant pots!

    Timber back doors provide a lifespan of up to 30 years

    Timber is notoriously robust, making it ideal for use as door material. Our timber doors are available in four different styles: entrance front doors, French doors, bi-fold doors, and sliding patio doors.

    On all door styles, the dense frame of timber provides exceptional durability, heightening your home’s security and its ability to withstand even the toughest weather conditions.

    Using a single piece of treated hardwood timber, the thick core is a natural insulator, meaning that it will trap the heat of your home inside, enhancing the thermal performance.

    Our timber doors provide a lifespan of at least 30 years, and won’t warp or fade over time as we finish them in innovative coatings to keep them looking and performing as good as new. Homeowners can further elongate their lifespans with simple maintenance, including the occasional wipe-down with a damp cloth to remove any dirt. Applying a coat of varnish or wood protection once a year can also extend the door's lifespan.

    For those homeowners who are looking for a sustainable, economical, and environmentally friendly replacement back door, you can have the peace of mind that our timber back doors are the ones for you.
