The Essential Home Security Checklist: Locks, Windows & Entry Points

How secure is your home right now? Most people know their front door needs a good lock, but what about the side gate, the garage door, or those ground floor windows? This practical checklist covers every entry point that deserves attention.

The Front Door: Your First Line of Defence

Your front door handles most comings and goings, which makes it the obvious starting point. But "obvious" doesn't mean "covered" – many homes have front doors with significant weaknesses.

What to check:

• Lock type – Standard euro cylinders can be snapped in seconds. Anti-snap versions are designed to break safely without compromising security.
• Door fit – A door that rattles or has gaps around the frame won't lock securely, no matter how good the cylinder.
• Hinges – Exterior hinges should have security pins that prevent the door being lifted off.
• Letterbox – Without a guard, a determined intruder can reach through to unlock the door from inside.

The Back Door: Often Overlooked

Back doors are statistically more likely to be targeted than front doors. They're often less visible to neighbours and passers-by.

Common weak points:

• Glass panels – A back door with glass near the lock is an invitation. Consider a second lock positioned away from any glazing.
• Key-operated locks only – Thumb-turn cylinders on back doors make it easy for someone who's broken in to leave quickly with your belongings.
• Multi-point locks – Many uPVC back doors have multi-point systems that need all points engaging. If the door doesn't 'lift and lock', the mechanism may need attention.

Side Doors and Garage Entry

These secondary doors are frequently the weakest link. Garages often connect to houses internally, meaning a weak garage door effectively bypasses your front door security entirely.

Practical steps:

• Fit a proper deadlock to connecting doors between garage and house
• Consider defender plates on garage door locks
• Don't leave a remote in a car parked outside – it's an invitation

Windows: Ground Floor and Accessible Upper Floors

Ground floor windows are obvious targets, but don't forget first floor windows above flat roofs, extensions, or easily climbed walls.

Window security checklist:

• ✓ All window locks work and keys are accessible (but not visible)
• ✓ Handles turn smoothly and secure properly
• ✓ Frames aren't rotting or warped
• ✓ Locks meet insurance requirements

Older windows sometimes have worn locks that don't engage fully. Replacement handles with built-in locks are usually available and straightforward to fit.

Patio, French and Bi-fold Doors

Large glass doors are beautiful but can be vulnerable. Multi-point locking systems are essential, and the anti-lift mechanisms should be checked regularly.

For sliding patio doors, a simple security bar in the track provides an additional layer of protection that takes seconds to use.

Gates, Fences and Boundaries

Your boundary is your first opportunity to deter intruders. Side gates with simple bolts can be reached over and opened in seconds.

Consider:

• Key-operated or combination locks on side gates
• Anti-climb measures on fences if practical
• Motion-sensor lighting in side passages
• Thorny plants near vulnerable access points

Outbuildings: Sheds and Summer Houses

Sheds often contain tools that can be used to break into the main house. Securing your outbuildings protects both their contents and reduces break-in tools being handed to intruders.

Good padlocks, padbars that cover the fixing screws, and ground anchors for valuable equipment all help.
