How do you make doors more secure?

Door security is something to take seriously, and never more so than when buying new doors for your home.

It is important to assess the door’s construction and the materials used in its design; doors should come with clear indications of the security standards they meet.

Most importantly, you should pay careful attention to the number, type, and manufacturer of any locking mechanisms included in the door or available as upgrades.

All those points are explored in more detail below and apply equally to front and back doors.

Door choice and installation

All the doors we fit are sourced from suppliers known for their quality manufacturing and selection of robust and long lasting materials. They are tested against forced entry and meet industry standards for security, although these may vary according to the material and the door range.

Just as important as the composition of the door is how securely it is fitted. The type of framing used and how door and frame are fitted greatly influence not only tits operation but its overall security and resistance to break in. Since we fit all the doors we sell, we are able to ensure a high quality of workmanship at the point of installation, and we can guarantee our work.

    Hugh security, multi-point locks

    Multi-point locks are the standard fitment to all our doors, each having a minimum of three locking points, but many have five point locks. As you turn the key, they all lock simultaneously, anchoring the door to the frame. The advantage of multi-point locking over a conventional single door lock is in the support it provides, as the defended area is much greater and stronger.

    Yale door locks

    Secure your home with industry-leading Yale locks

    Our composite doors are fitted with Yale multi-point door locks. Yale are the largest specialist supplier of multi-point locks and respected for their quality and security.

    Developed to achieve exceptional standards of security, Yale door locks include precisely fitted deadbolts, hooks and latches into their multi-point mechanism design.

    Defeat lock breakers with anti-snap lock cylinders

    Lock cylinders are integrated into the design of most residential doors. They’re a functional hardware option for homeowners as they’re easy to operate and additional keys can be easily cut. The lock cylinder, the part where the key is inserted contains the spring-loaded pins that when the key is turned allow the door to open. When locked, those pins keep the cylinder from turning.

    Lock snapping is a technique whereby force is applied to the lock cylinder, which makes it snap into two. Burglars can then expose the locking mechanism and damage it fairly easily to gain access. By fitting an anti-snap lock into the cylinder, break in attempts using lock snapping are much less likely as their more robust engineering means they can withstand the forces typically used.

    Adding extra door security with a mortice lock

    If you’re asking yourself ‘what is a five-lever mortice lock?’, the answer is one of the most common types of door lock in which a bolt is driven into the door frame when the key is turned.

    They are popular as they are good at withstanding forced entry—it’s rarely the lock that breaks but the door frame. When you are looking for household insurance you will often find that five-lever door locks influence the quote.

    Night latches, door security chains and sash jammers

    Additional security upgrades can be specified for many of our replacement doors. But how does each make a front door more secure?

    • Night latches – These are fitted to the inside of the door and operated from the outside by turning the key to bolt the locking mechanisms into the door frame. A key isn’t needed to unlock the door from the inside, as a safety in the event of a house fire.
    • Door security chains – Another supplementary feature that prevent access from the outside when you open the door, by limiting the door’s opening.
    • Sash jammers – These devices stop the door from being opened if the main lock has been compromised by a burglar. They bar the door from being opened with a lever that cannot be released unless it is manually pressed down by the homeowner inside.
