Outbuildings, garages, and sheds are often overlooked when it comes to home and business security. However, these structures are frequent targets for burglars, as they often contain valuable tools, bikes, vehicles, and equipment. Unlike main buildings, outbuildings tend to have weaker locks, fewer security measures, and are sometimes located in secluded areas, making them easy targets.
If you store anything of value in a shed, garage, or other outbuilding, ensuring it is well-protected is essential. In this guide, we’ll cover the best ways to secure these spaces and deter criminals from gaining access.
Why Are Outbuildings at Risk?
Garages, sheds, and other external buildings are prime targets for break-ins because they:
- Often contain expensive tools, garden equipment, and bikes.
- Are less frequently used, making break-ins less likely to be noticed immediately.
- Tend to have weaker locks and hinges than main buildings.
- Are often situated in darker, hidden areas, making it easier for thieves to operate unnoticed.
By improving security, you can make these areas less attractive to burglars and reduce the risk of theft.
Choosing the Right Locks for Sheds and Outbuildings
One of the most effective ways to secure your outbuildings is by installing strong locks. Standard locks that come with sheds and garages are often flimsy and easy to break. Consider upgrading to the following:
1. Heavy-Duty Padlocks
Use weather-resistant, anti-cut padlocks made from hardened steel. Choose a model with a closed shackle design, which makes it harder to cut with bolt cutters.
2. Mortice Deadlocks
For garages and sturdier outbuildings, a five-lever mortice deadlock provides excellent security. These are insurance-approved and harder to pick or force open.
3. Hasps and Staples
Reinforce doors with heavy-duty hasps and staples that cannot be unscrewed from the outside. These should be made from hardened steel and fitted with strong bolts rather than screws.
4. Keyless Smart Locks
For garages or outbuildings used frequently, a keyless smart lock provides convenience while ensuring security. Many models allow remote access control and activity tracking.
Reinforcing Doors and Windows
Even the best locks won’t be effective if doors and windows are weak. Reinforce these entry points to reduce vulnerabilities.
1. Upgrade Doors
Solid wood or metal doors provide better security than thin wooden or plastic doors.
Strengthen doors with horizontal bars or steel reinforcements to prevent them from being kicked in.
2. Install Window Locks
If your shed or garage has windows, install key-operated locks to prevent burglars from opening them. Consider securing glass with window film to make it harder to break.
3. Cover Windows
Use frosted window film or blinds to prevent potential thieves from seeing inside. If burglars can’t see valuables, they’re less likely to target the space.
Enhancing Perimeter Security
Preventing criminals from reaching your outbuildings in the first place is an essential part of security.
1. Install Security Lighting
Bright motion-activated lights around sheds and garages can startle intruders and make them more visible to neighbours or passers-by.
2. Secure the Perimeter
Use high fences and lockable gates to restrict access to your garden and outbuildings.
Consider thorny bushes or gravel driveways, which make it harder for burglars to approach quietly.
3. Use CCTV and Alarms
Smart security cameras positioned near garages and sheds can capture footage of any suspicious activity.
A garage or shed alarm will alert you if someone tries to break in. Some models send alerts directly to your smartphone.
Securing Tools and Valuables Inside
Even if burglars manage to break in, making it difficult for them to steal anything can help minimise losses.
1. Lock Up Valuables
Store expensive tools, bikes, and equipment in a lockable cabinet or ground anchor inside the shed or garage.
2. Use Security Marking
Mark valuable items with a UV pen or engraving to make them harder to sell and easier to trace if stolen.
3. Keep an Inventory
Keep a record of all expensive tools and equipment, including serial numbers and photos, so you can report thefts quickly.
How Often Should You Check Your Shed or Garage Security?
Security should be regularly reviewed to ensure everything is in working order. Consider these checks:
- Monthly inspections: Check locks, hinges, and security devices for signs of wear or tampering.
- After storms or bad weather: Ensure locks and doors haven’t been weakened.
- Before holidays or extended absences: Double-check that all security measures are in place before leaving for an extended period.
What to Do If Your Outbuilding Has Been Broken Into
If you discover a break-in, follow these steps:
- Do not enter if you suspect the burglar is still inside. Call the police immediately.
- Take photos of any damage for insurance claims.
- Make a list of stolen items and report them to the police.
- Improve security by upgrading locks and adding extra deterrents to prevent future break-ins.
