Why You Shouldn’t Overlook Your Window Locks

When thinking about home security, your front and back doors probably get most of the attention. However, your windows are also potential access points.

A damaged, loose or poorly fitting window lock can make a window less secure. And because window locks are used less frequently than door locks, window issues can sometimes go unnoticed.

Checking your window locks should therefore form part of your general home security. Here’s what to look for and when a repair or replacement may be needed.

Window locks serve several purposes. But most importantly, they help prevent your windows from being opened from outside.

Locks and handles also help windows close correctly, keeping a tight seal. But if a window no longer closes tightly against its frame, the problem may be caused by worn hinges, damaged seals, frame movement or misalignment rather than the lock itself.

Secure window locks help make unauthorised entry more difficult and remove an obvious weakness in a property's security.

Burglars do not always enter through a door. A window can provide an alternative entry point, particularly if it is hidden from view or easy to reach

Ground-floor windows deserve particular attention. The same applies to windows near garages, flat roofs or other structures that make upper floors more accessible.

Although no lock can guarantee protection against every attempted break-in, well-maintained window locks can act as an important deterrent.

Some windows may need to be open but restricted to reduce the risk of falls, particularly where young children can reach them. A window restrictor is a safety catch that limits how far a window can open while still allowing ventilation.

However, restrictors should not interfere with any window that needs to provide an emergency escape route.

A window that closes correctly should sit properly against its seals. If the locking mechanism is damaged or misaligned, the window may not pull tightly into position.

You might notice a draught, hear more outside noise or have difficulty getting the handle into its locked position.

Replacing or adjusting the closing mechanism can sometimes resolve the problem. However, draughts can also be caused by damaged seals, hinges, frames or glazing.

A locksmith or glazing professional can identify the cause before recommending repairs.

The right lock depends largely on the type and age of your windows.

• Modern uPVC and aluminium windows commonly use multipoint locking mechanisms. Turning the handle operates several locking points around the window.
• Casement windows can use different handles, catches and locks, depending on their design. Older timber windows may use separate window locks or locking handles.
• Sliding windows require a system designed to prevent the moving section from sliding open. Sash windows also have their own catches, fasteners and additional security devices.

Your Window Type

A lock designed for a sliding window will not be suitable for a casement or sash window.

If an existing lock has failed, it may be possible to replace the damaged component rather than changing the entire window.

With older windows, compatible replacement parts can sometimes be harder to identify. A locksmith can inspect the existing hardware and determine what options are available.

Look at how accessible each window is from outside.

Ground-floor windows and windows beside flat roofs, extensions or other climbing points may require greater security. Also remember to review any windows hidden from public view.

A secure window still needs to be usable.

Frequently used windows should have locks that people can operate easily.

So, it makes sense to think about how each window is normally used before adding extra security devices.

Incorrectly fitted components will often prevent a window from closing properly or place additional strain on handles and mechanisms.

If the main locking system has failed, professional window lock repair may be more suitable than attempting to replace individual parts yourself.

Window lock problems are not always obvious. In many cases, the first sign is simply that the window feels different when you use it.

You may find that the lock has become stiff or loose. The window might need extra force to close, or the handle may no longer turn fully into the locked position.

Other warning signs include visible damage, loose fittings, broken keys and locking points that no longer engage correctly.

Do not force a window’s handle. It could be down to a misaligned window rather than the handle itself, and forcing it could damage other parts of the mechanism.

Window locks do not require much day-to-day maintenance, but occasional checks can help you spot problems early.

Keep the mechanism and surrounding areas clean and look for loose screws or visible damage. If it needs lubrication, check what products the manufacturer recommends for that particular mechanism.

Pay attention to changes in how the window opens and closes. A lock that suddenly becomes stiff may indicate movement or misalignment elsewhere in the window.

Small issues can sometimes be corrected if they are caught in time.

A loose handle or minor component may be repairable. If the locking mechanism itself is badly damaged, worn or no longer available, replacement is probably the better option.

And carefully assess any damage following an attempted break-in. The problem may be an issue with the frame, handle, hinges or glazing.

A professional can inspect the complete window.

Consider calling a locksmith if a window will not lock, the handle does not move as it should, or part of the mechanism has visibly broken.

Doors are the obvious place to start when checking your home's security, but windows deserve the same attention. A burglar won’t turn down an opportunity.

Check that your windows close properly and that their locks engage without excessive force. And look for damaged handles, loose components or signs that the window has become misaligned.

Keeping window locks in good working order is a relatively simple part of maintaining a secure home. If something no longer works as it should, getting it checked can help prevent a small fault becoming a larger repair.
