Garden sheds are often overlooked when it comes to break-ins. Despite holding lots of valuable equipment, most people don’t take the time to effectively secure their shed, with a padlock typically being the first and last line of defence against break-ins.
However, shed break-ins are becoming an increasingly common problem, mainly because thieves see them as an easy target due to the lack of security. Given that your average shed is storing expensive gardening equipment like lawn mowers, hedge trimmers and shredders, it makes sense to invest in a good security system - and we aren’t talking about a basic lock and key!
Choosing the best shed alarms is one of the main ways to protect your structure from break-ins and theft. Affordable and easy to install, the alarm produces a loud siren that will alert you to any security threats, deterring any would-be thieves that are trying to break in.
With this in place, you can rest easy that all your valuables are safe and secure inside of the shed, and anyone that is brave enough to try and steal from you will be in for quite the shock! Of course, like any product, not all alarms are made equal, so be sure to buy a reliable product so that your shed is no longer an easy target.

General Home and Garden Security Tips
Shed security doesn’t end with a good alarm system - there are a lot simple tricks you can use to greatly increase your shed and home security!
Upgrade You Shed Lock
When you combine a robust shed lock with an alarm, chances are nobody is getting anywhere near the inside of the building. Most garden sheds come with a basic lock, so consider upgrading this to something like a strong hasp and large padlock, which don’t cost much and can be installed in under an hour.
The same can be done your house locks too! Adding new locks is a simple but effective way of increasing home security
Make it Hard to See Inside
Shed windows bring some welcome light into the building but it can also advertise all your stuff inside. Some thieves see the contents of a shed and find it too good to resist, which is why you should always obscure the windows to make it hard to see inside. Try adding an old set of roller blinds inside the shed!
Keep Your Garden Clear
This may sound obvious but try not to leave any tools or equipment lying around in the garden unattended. Not only does this increase the risk of them being stolen, they could also be used to break into your shed or house.
For instance, if you leave ladders lying around it could be used to gain access to your house via a window, while any tools left out could be used to break the shed lock or jar open your windows.
