Security research for homeowners
Garage door security, without the sales talk
A garage is often the softest entry point on a property: it holds bikes, tools and sometimes a connecting door into the house, yet it is protected by whatever door was fitted decades ago.
This guide separates the features that meaningfully raise the effort required from the ones that mostly appear in brochures.
Where doors are actually attacked
Old up-and-over doors are vulnerable at the centre latch and at the bottom edge, where the panel can be levered. Roller curtains are attacked by lifting the slats out of the guides. Sectionals are strongest but only as good as their frame fixings.
- Levering the bottom rail on a lightweight single-skin door.
- Lifting a roller curtain where no anti-lift device is fitted.
- Pulling the emergency release cord through the top gap on an automated door.
- Removing a rotten timber subframe that the whole door depends on.
Features that make a real difference
On automated doors, the motor itself should hold the door closed and resist forcing. On manual doors, multi-point locking into the frame at both sides beats a single central latch every time.
- Anti-lift devices on roller doors.
- Motor locking or an integral deadlock on automated units.
- Two-sided locking on manual doors rather than one centre point.
- Sound frame fixings into masonry, not into a decayed timber frame.
- A shielded or shortened emergency release on doors with a gap at the head.
The cheap wins people skip
Fit a proper lock to the internal door between the garage and the house — it is often a lightweight door on a latch. Anchor bikes and tools to a ground or wall anchor rather than relying on the garage itself. Add a light on a sensor: garages are usually the darkest part of a frontage.
None of these require a new door, and together they change the risk profile more than an upgrade on its own.
Questions we get asked
- Are electric doors more secure than manual?
- Generally yes, because a good operator holds the door shut and there is no external handle or lock to attack. The gain depends on the motor being specified for locking.
- Can a roller door be lifted from outside?
- A cheap roller with no anti-lift protection can be. Quality installations include anti-lift devices and a motor that holds the curtain in the guides.
- Is my old up-and-over door a weak point?
- Very often, particularly single-skin doors with a single central latch and an aging timber subframe. It is the most common security upgrade we are asked about.
- Does insurance require a specific standard?
- Policies vary. Check your wording for requirements about the internal door and about what is stored in the garage; we can supply the specification of what we fit for your insurer.
- Can you improve security without replacing the door?
- Sometimes. If the door is structurally sound we can look at locking, anchoring and seals. If the frame has failed, replacement is the honest answer.
