Windows

According to police, windows are the way that most burglars enter a home. So it figures that if you want good security in and around your home, you need to check that your windows are OK.

If they are timber framed make sure they are robust and free from wood rot. Also ensure they are fixed with wooden beading which are fitted with security screws rather than pins or putty. Likewise, metal-framed windows should be checked for corrosion and loose catches.

Modern PVCu windows are less prone to deterioration, but have their own problems associated with security. Perhaps the best known of these is the positioning of the beading. Some PVCu units, especially the older ones, have the beading (these are strips that hold the window in place) fitted on the outside. Whilst this might make them easier to fit, it also makes windows easy for a burglar to remove. Glazing clips and security tape can help here.

Security tests developed by British Standards help to indicate which windows are more superior. PAS 011 is a test of the whole system, including hinges and latches (but not the actual glass). Look for BS 7412 - PAS 011 for PVCu systems, or BS 644 - PAS 011 for timber. If displayed, these tell you that the windows have been tested and have reached the standard. BS 4873 applies to aluminum frames and BS 6510 to steel.

Good key operated window locks make the overall security of your home much better, so get some fitted. Many insurance companies now insist that these are fitted - so check your policy closely. PVCu systems tend to use locks. If not they can be retrofitted, but make sure this is done properly otherwise you may damage the unit, which could prove expensive.

When it comes to the glass itself, it's worth noting that modern double glazed units are hard to break, although it's not impossible for a determined thief to smash them. Laminated glass offers the best protection. If used on both the outside and the inside, laminated glass is incredibly secure, but using it on the inside alone is enough. West Midlands police recommend laminated glass of at least 6.4 mm thick that conforms to PAS 011.

One good tip for making your windows even more secure is to have Venetian blinds fitted. These are not just good for stopping people seeing into your home during the day, without cutting out the light. Burglars hate them, because they are awkward to get past and make a lot of noise, something no thief is all that keen on.

Window Locks

A third of burglars get in through a window.

If you are replacing windows, take the opportunity to install new ones that are to British Standard BS7950 'Windows of Enhanced Security' and consider using laminated glass, particularly in ground-floor and accessible windows, as this is much harder to brake.

Otherwise, window locks that can be easily be seen from outside may put some thieves off, because the thief would have to break the glass and risk attracting attention. And even if they do break the window, they still can't open it. They would have to risk cutting themselves climbing through the broken glass.

Home security and DIY shops sell inexpensive, key-operated locks to fit most kinds of window lock. You may need more than one window lock, depending on the size of the opening you need to secure.

Fit window locks with keys to all downstairs window and windows that are easy to reach - for example, those above a flat roof or near a drainpipe.

Even small windows such as skylights or bathroom fanlights need locks. A thief can get through any gap that is larger than a human head. Remember to keep windows locked.

Remove the keys and keep them out of sight in a safe place.

Louvre windows are especially vulnerable because thieves can easily take the slats out of the frame. Glue the slats into place, and fit a special lovre lock. Better still, replace them with fixed glass.
