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, we manufacture our new doors 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, such as security chains and night latches.Get a free quote
