Three central squares of glass running from the top downwards make up the design of our Lincoln composite door, with a flat slab grained like a traditional timber door but in fact having a glass reinforced plastic (or GRP for short) skin that's both uv stable and easy to clean. Choose a finish from our wide range of colours such as red or blue, pastels like olive and dusk, the woodgrain oak or rosewood, or the greys anthracite, slate and silver. The frame is white by default, but can be colour matched to your door. The same is true for any solid panelling that may be part of top lights or side panels.

The Lincoln door is pre fitted with one of our catflaps or pet doors (for small to medium sized dogs), with with manual locking and microchip options available. Manual require you to lock by hand, while SureFlap brand microchip catflaps and pet doors are activated by your cat or dog's microchip.

Our composite external doors are highly secure and up to six times more thermally efficient than timber doors. Security features include toughened glass, a high impact GRP skin, steel reinforcement within the frame, and a police approved, insurance approved Secure by Design multi point locking system. To help keep your home warm, warm edge tech spacer bars within the glass reduce heat loss, and Q-Lon gasket weatherseals (which are in fact guaranteed for life) will create a solid seal against the cold outside.

Our composite doors are fully installed without full payment beforehand, so you pay in full after your new door has been fitted (orders over £3000 will require a deposit). Our fully fitted service includes a free survey to get the right measurements for your door and advise you of any changes or requirements to your order as a result. It also includes free uplift of your old door, so you won't have to worry about disposal yourself. After installation and payment, we supply you with a guarantee, and should you need aftercare for your door our Projects Team will be on hand to assist you.
