In order to ensure the safety of yourself, family and home, it is essential that all windows and doors are equipped with the highest level of security. According to an article featured on Reader’s Digest, most of the time, there is no need for burglars to “break into” a property as they can let themselves in through weaknesses in the doors and windows. In fact, 34% use the front door, 22% use the back door, and 33% make their way through ground-floor windows. With these shocking statistics in mind, we have put together a host of tips on how to burglar proof windows and doors, protecting your home against criminals.

A Guide On How To Burglar Proof Windows And Doors

Everyone should always feel comfortable, safe and at ease in the comfort of their own home, which means that ensuring that entry points are secured is imperative. Luckily, there is an abundance of ways that you can deter intruders from entering through windows and doors. Here we have put together a number of techniques to add an extra layer of protection to your property.


According to Crime Prevention Security Systems, windows are one of the most common ways that burglars enter the home as they are seen as the weakest point of a property. While many assume that smashing the windows is the only way to break in, this catches the attention of those inside, neighbours and passersby. This means that most intruders target defects in windows, including the lack of security, to break in discretely. If your home is still fitted with old, wooden single-glazed windows, then it is most definitely time for a replacement. You can find more information on how to choose the perfect windows for your home in our previous article.

Alternatively, if you have modernised windows, yet feel as if you lack security, we have put together several ways that you can boost your protection. Here we will run through the following:

Internally Beaded Windows

Glazing in windows is held into place with a small strip, made from either timber, aluminium or plastic, based on the frame material that you opt for. This small strip, also known as beading, runs along the edges of the window sash. While in the past, most homes were equipped with external beading, it has now thought that placing the bead on the inside boosts window security. As the beading will run alongside the interior of the frame, it becomes incredibly difficult for intruders to remove the beading. The only way that they would be able to remove the strip of material would be to smash the glass and reach into the home, which will inevitably wake up those inside or set off alarms. If the beading was to be fitted to the outside, on the other hand, all burglars would need to do is peel away the strip and then remove the glass, creating an easy way to enter your home without making a noise.

If you are considering replacing your windows, then we strongly recommend opting for a design featuring internal beading as opposed to external. Our team would be more than happy to schedule a consultation to discuss your requirements, including ways to enhance the safety of your property. With many years of experience installing windows in Milton Keynes, they can advise you on the best route to maximise results.

Key Locking Handles

While it may seem like a straightforward security measure, homeowners should never underestimate the effectiveness of key locking handles. Almost all modern windows should be designed equipped with locking handles as they make it incredibly difficult for potential burglars to wriggle open any windows. This feature is not only essential in terms of safety, but also for those with young children. Having the ability to lock windows, particularly those in two-storey properties or higher means that window-related safety risks can be minimised. You can find a full guide on how to baby proof your windows and doors by heading over to our previous article.

If you opt for locking windows to protect your children, then you must also ensure that the keys are tucked away out of reach and sight. However, if you do not have children, then it is recommended to leave the keys inside of the locks. This prevents intruders from being able to pick the locks, as well as eliminating the stress of trying to find the keys in the event of an emergency.

Locking Windows

Opening Restrictors

Similarly to key locking handles, opening restrictors are a simple yet highly effective way to burglar-proof windows. With an opening restrictor installed, you will still be able to open your windows, but the opening will be restricted when it reaches a fixed distance. While the fixed distance is most commonly 100mm, it can be altered if required.

In fitting a restrictor, even if an intruder was to manage to open the window from the outside, the gap will not be big enough for them to climb through. Restrictors are not only vital on the ground floor to deter burglars, but also on higher-level floors to minimise the risk of falling. Although windows restrictors are only a legal requirement in establishments such as hospitals, care homes and schools, they should most definitely be fitted in every property. Again, this is particularly important for those with small children, who are at the most risk of falling. For more information on where window restrictors are required, take a look at Jackloc.

Toughened Glass

Having specialised in double glazing in Milton Keynes for many years, we cannot stress enough the importance of ditching single-glazed windows for modernised alternatives. Not only is double-glazing more thermally efficient, longer-lasting and easy to maintain, but they are also considerably stronger. They take immense pressure to break and are difficult to force open from the outside, meaning that by replacing your glazing, you can reap the benefits while adding an extra layer of security to your home. If you are hoping to increase protection even further, then you can opt for a laminated or tempered glazing option, which is made stronger by going through a repeated heating and cooling process.


Along with windows, it is also imperative to ensure that all doors are fully protected against intruders. The most common methods for breaking into properties through doors include kicking or cutting through the door slab, snapping off handles or levering the door open at the lock. Therefore, both front and back doors must be secured using one or all of the following methods:

Install Home Security

Thanks to the constant evolution of technology, there are now ways to digitalise almost every component of your home. The most effective way to have full control over the security of your property is to fit a home security system. Home security systems are powered by the internet and are equipped with a range of security features including wireless security cameras, motion detectors, door locks and much more. Functions are most commonly controlled via a smartphone app, meaning that you can log in and check your home from any location, at any time. Most homeowners opt for installing the system to their front and back door, allowing them to store footage of exactly who approaches, enters and exits the property.

Multi-Point Locking

There is now an abundance of options when it comes to increasing the security of locking systems. To achieve the highest level of protection, we suggest choosing a system with as many locking points as possible. While there are no set rules with regards to multi-locking systems, those with eight or more locking points are guarantee to provide maximised safety.

Similarly to a conventional lock, a multi-locking system is still opened and closed with a key, yet is installed to the body of the door, then locks into the frame. With a single turn of the key, the door will be bolted into the frame while locking it into place at several points. Although multi-locking systems are most commonly incorporated into UPVC and composite front doors, they can be installed wherever a homeowner feels necessary with some opting for installation to their patio doors. For instance, many of our clients who wish to build one of our conservatories in Milton Keynes choose to fit additional security to their conservatory doors, meaning that no one will be able to break into their home from the garden.

More information on the different types of door locks available can be found on the Master Locksmiths Association website.

Door Chain

As a traditional door security feature, chains are most commonly fitted to the front door and are designed to restrict how far that the door opens. Chains are most effective at preventing “distractions burglaries” where the intruder will knock on your front door then force their way past you, into your home.

One of the most significant benefits of a door chain is that it can be installed independently without the need to enlist the help of a professional. However, it is imperative to ensure that you are confident with the process before going ahead as a poorly fitted chain can be even more dangerous than no chain.

There are two different types of chains to choose from; a conventional restrictor and a lockable door chain. A traditional chain is fitted to the wall next to the door frame and features a ring which goes around the handle or a metal attachment which is fitted to the door. Lockable chains, on the other hand, can be locked from both the inside and out, ideal for those with children or the elderly.

Keeping Your Property Safe From Intruders

While no one likes to imagine the thought of an intruder making their way into their home, it does unfortunately happen. This means that it remains imperative for several preventative measures to be implemented, keeping you, your family and your home safe from criminals. It is entirely your choice which one of the above techniques that you use to protect your home. Of course, the more security measures that you install, the more at ease you will feel that you will successfully deter burglars. It is always better to be safe than sorry!
