    The most effective way to secure your Kent home

    Being the initial entry access to a property, its vital that your front and back doors are made from robust and long-lasting materials. Tired and weak looking doors are commonly sought by intruders as they’re easier to break into. As leading double-glazing installers, our doors are made from high-quality materials, using pioneering fabrication techniques to maximise their durability. Their sturdy door panels, tightly fitted frames, multi-point locks and toughened glazing work together to provide a resistant door that will stay intact from the toughest forces.

    For peace of mind, our replacement doors are rigorously tested to ensure their protection from common burglar techniques, including lock picking and drilling. As our doors are custom designed, we can include additional security features too.

    A new door that will reduce your carbon footprint

    With a new door, you’ll notice that the temperature inside of your home is more comfortable all year round as they are designed to be draught-free, so cold spots are eliminated. So, by upgrading your doors, you’ll even save money on your heating bills, making them an even better investment.

    Our doors can achieve A+ energy ratings, the best capabilities available on the market. Their inventive designs incorporate features such as advanced double glazing or comfort glass, warm edge spacer bars, chambered door frames, airtight profiles and thermal break barriers. Together, they resist energy loss, retaining the warmth inside of the room.
