The 5 Most Common Ways That Burglars Break Into Houses

One thing that all the most common break-in methods have in common is that they are preventable with the correct physical security measures in place.

1) Most Intruders Gain Access Through the Front Door

The most common way for intruders to break into a property is through the front door. When this happens it is usually a case of forced entry due to inadequate locks and security measures in place.

There are various methods intruders use to break into a front door.

Lock Snapping

Lock snapping is common with vulnerable UPVC doors. It usually occurs when the lock is not up to the latest standard. This will be something easily visible to a burglar as the cylinder will protrude from the door. It can then be grasped with a tool and snapped.

Lock snapping on UPVC and composite doors can be prevented by installing an anti-snap cylinder. For the best security choose a British Standard 3 Star Diamond Sold Secure Rated cylinder. You can read about Why Anti Snap Locks are a Must for UPVC Doors here.

Forced Entry

I do see a considerable amount of access by forced entry. This usually happens when it is obvious that a door isn’t strong or glass is smashed.

This ex burglar shows just how quick and easy it can be done.

There are a number of security solutions for reinforcing a weak door to prevent forced entry.

  • Birmingham Bar
  • London Bar
  • Hinge Bolts

Security grilles for house windows and doors are probably the best form of physical security as well as a massive deterrent for burglars.

Lock Bumping

Lock bumping is a method mainly used by locksmiths but it is good to have high security locks that are resistant to lock bumping for the best security. Criminals are always developing new techniques of gaining access.

Lock Picking

The same applies to lock picking which is less common as it takes time but it is advisable to have maximum security front door locks resistant to lock picking.

Letterbox Entry

It is important that your lock is positioned so that it cannot be accessed through the letterbox. Also leaving keys visible through the letterbox is not a good idea. An experienced locksmith will know where a letterbox and lock should be positioned to maintain security.

2) Many Burglaries are Through a Ground or First Floor Window

There are a number of reasons window security can be compromised.

Windows Left Open

It is common for windows to be left open in the summer, making access easy for the opportunist burglar.

Poor Window Security

Another issue is windows without locks or windows being smashed. Windows should always have key operated locks for security and insurance purposes.

Incorrectly Installed Double Glazing

Intruders can remove UPVC windows which have been incorrectly installed.

This is an issue that I have seen on a number of occasions. It is important that the beading on double glazed windows is on the inside and not the outside. Something that is clearly visible and intruders look for.

The beading is to allow the pane of glass to be replaced. If it is on the outside the pane can be popped out in seconds as you can see in the video in this article.

Anyone who has double glazed windows should check that they are beaded on the inside! If it is on the outside contact the company that installed them and make a complaint. This is a great security risk!

Professional window bars installation provides high security. Bespoke security grilles for windows can be designed to look discreet or be used as a feature. Fixed or collapsible security grilles can be an excellent deterrent and prevent access.

3) Intruder Access Through a Back Door is Common

Back doors have the advantage to intruders in that they can often be concealed from the main street. This gives an intruder more time to gain access through forced entry and even smashing the glass. Also many back doors can be vulnerable and intruders will seek out patio doors with low levels of security.

UPVC patio doors without the latest high security locks are a target. Read about How to Make French Patio Doors More Secure here.

Sliding doors are perhaps the easiest means of access when they have inadequate locks. They can literally be lifted off the runners. Read about Sliding Glass Door Security here.

4) Some Intruders Gain Access Via a Garage

Access to a property via a garage is less common but does happen. Find out about The Best Garage Security and How To Burglar Proof a Garage here.

5) Access Through to an Unlocked Entrance

Access through unlocked doors & windows is the least common method of burglary, yet it does happen more often than you would expect. Good habits of locking up when you go out and at night are really important because intruders are opportunists and you could be unlucky.

The worst thing about a burglary without forced entry is that your insurance policy will not pay out if you have not secured your property as specified in your home contents insurance policy. Read our Guide to Insurance Approved Locks here.

Most burglaries are a result of poor attention to detail when it comes to security.

Burglary warning signs

Quite often there are signs that burglars are targeting an area. Be on the look out for tell tale signs that intruders are looking for opportunities. Some burglary warning signs are;

  • Strangers asking for help or to use the toilet
  • Cold callers
  • Strangers taking photos
  • Unfamiliar vehicles
  • Markings to highlight a target
  • Flyers or stickers

If you haven’t got Neighbourhood Watch set up in your area it is well worth doing.
