Security - Protective Gardening

Most burglars look for easy ways of getting into a house and two-thirds of them gain entry via the back garden. But by taking a few simple precautions you can reduce the risk.


Sash Windows

To secure, install a key operated lock or drill a hole slightly downward through a top corner of the bottom window into the bottom of the top window, placing a solid pin or nail into the hole to prevent the window from being opened.

Louvre Windows

These are difficult to burglar-proof as individual panes of glass are easily removed though applying two-part epoxy resin to each pane of glass helps to prevent this. ldeally replace with solid glass.

Casement Windows

Use key locks and keyed the same for all windows. Basement windows are especially vulnerable, protect with grates or grilles but allow for opening in an emergency. Also, prune plants that hide windows and cut back branches that could help thieves climb through them. Store ladders in a locked garage or shed and not outside allowing easy access to a tirst-floor window.


Exterior Doors

Use quality locks for all entry doors which should be constructed of solid 1 3/4" thick hardwood, or be metal-clad. For added security use hinge bolts and strong hinges with non-removable or hidden pins. Install a wide-angle viewer and stout door chain. Use double-cylinder deadbolts which when double-locked need a key to unlock on BOTH sides so if glass is broken, burglars cannot gain entry by reaching in, and even if they enter your home through a window, they cannot remove property through the doors. Make sure your house number - five inches minimum - is clearly mounted on a high contrast background and is easily read from the road at night. Emergency vehicles need to find your home in case of an emergency.

Double Doors

Flush bolts installed at the top and bottom of the inactive door of a pair of doors offer additional security as an intruder cannot get at these devices to tamper with them if the doors are locked.

Sliding Doors (and windows)

Sliding glass doors can be an easy point of entry. To improve security install keyed locking devices that secure the doors to the frame or track, adjusting the track clearances on the doors so they cannot be pushed out of their tracks and placing a strong metal or wooden bar along the track to prevent the doors from being opened.


It is important to have some form of boundary marker providing a threshold which unauthorised visitors have to cross and the front of your home should be in full view of neighbours and passing pedestrians. Keep fencing, brickwork and planting low, so that anyone acting suspiciously can be seen. Plants and shrubs should ideally be kept to around four feet in height and the lower canopy on trees at least eight feet from the ground. However, most burglars enter through secluded rear or side windows and doors, so prevent access to this area.


- The minimum for protection is 6ft high closeboard, topped by trellis as it is fairly frail and will not allow a firm handhold.


- A rear wall should be at least 6ft high with non-setting anti-climb paint applied to the top. Gates - To guard the side and rear of your home, install a quality lockable wrought iron or steel gate that cannot easily be climbed. Mortice locks, padlocking bolts, hasp and staple or hardened steel chain and close shackle padlocking arrangements are effective. The garden is your first line of defence. Consider barrier planting to deter unwanted visitors; as well as planting on boundaries, plant around drainpipes and beneath ground floor windows making forced entry more difficult. Some plant suggestions follow (AGM = award of garden merit):

One of the best and most cost-effective deterrents to burglary. Install floodlights at opposite corners under eaves so the bulbs cannot be removed, to illuminate the walls and eliminate hiding places. Install passive infra-red (PIR) sensor exterior lighting near all points of entry to help identify night time visitors, but to give a sudden burst of light, to alarm a potential thief. Timers or photoelectric cells can automatically turn on the lights at dusk and off at dawn. Trim plants that would conceal activity near entrances and light dark corners where thieves could hide. The rear garden is more private than the front and PIR switched halogen units, located out of reach to prevent tampering, are a strong deterrent to intruders. When not at home, light timers are useful for giving an impression that the house is occupied. Operate lights in several rooms and use logical lighting patterns. Some light timers offer random settings that are useful for lights in kitchens and bathrooms. If you are away for several weeks, have the post office hold your mail, stop newspaper deliveries, and ask a neighbour to watch your home and place a full dustbin out on collection day. Arrange for lawn care. Never leave messages on answering machines indicating that you are away.


If you continually set off false alarms, your neighbours and the police may not respond. A highly visible bell box with a stroboscopic light fitting can act as a powerful deterrent to the thief.

Garden Sheds

Many people keep tools in their shed such as spades which can be used to force entry to your home. Everything of value should be chained and padlocked to each other or ground anchors. A suitable hasp, staple and padlock should be fitted to the door and frame. Hinges are usually exposed, so fit non-return screws to prevent their removal. The windows should also be screened with curtains and locked.


Detached garages, like sheds, may provide tools to help a thief obtain entry to your home and side doors should be fitted with a mortice lock to BS 3621. Double opening wooden doors should have a high security close shackle padlock and padbar; up and over aluminium doors specialist mortice locks and padlocking bolts or hardened steel hasp and staple. Close shackle padlocks are recommended to secure both sides of the door and sliding hasps can also be used on the inside to prevent the lifting of the opposite side and crawling in under the door. Thieves do not want to risk being seen and doors leading from attached garages could allow them concealed access into your home. Up and over doors can be secured from the inside by drilling holes into the two channels immediately above the runner wheels when the door is in the closed position. Padlocks inserted through the holes prevent the door being opened from the outside. The connecting door to the house should be fitted with a mortice lock to BS 3621. Mortice bolts should be fitted a foot from the top and bottom of the door. As with sheds, windows should be screened and locked.
