Ground-Floor Windows: The Entry Point Burglars Check Before Your Front Door
Most homeowners focus their security on the front door. Burglars focus somewhere else. Across Lancashire, a significant proportion of residential break-ins happen through ground-floor windows — particularly those at the side or rear of a property, hidden from passing traffic and neighbours. A window with a broken lock, a seized handle, or a mechanism that no longer holds the frame closed is not just an inconvenience. It is an invitation.
Window lock repair in Chorley is one of the fastest, most affordable ways to close this gap. First Pick Locksmiths repairs and replaces window locks and handles on every common window type across Chorley and the North West. We carry the most common parts on every van, charge no call-out fees, and treat windows stuck open as urgent, priority calls.
Call 07902 510798, and we will get your windows secure.
What Causes a Window Lock to Stop Working?
Window locks are small mechanisms that do thousands of cycles over the life of a window. When they fail, the cause is usually one of four things.
The Gearbox Inside the Espagnolette Has Worn Out
Most uPVC windows use a strip mechanism called an espagnolette that runs along the opening edge. When you turn the handle, the gearbox inside this strip moves a series of small locking cams into matching keeps on the frame. After years of use, the internal gearbox wears smooth or cracks. The handle still turns, but nothing engages. This is the single most common window lock fault we attend across Chorley.
The Handle Itself Has Failed
Window handles contain a small spring that returns the handle to its resting position. Springs wear out. When they do, the handle flops, jams, or will not complete its full turn. A new handle usually fixes the problem in minutes.
The Window Has Dropped in Its Frame
Hinges on casement windows wear out over time, allowing the window sash to sag. Even a small drop can misalign the locking cams and keepers, creating the impression of a lock failure when the mechanism itself is fine. Fixing the alignment is often cheaper than replacing the lock.
The Key Has Been Lost or Snapped
Modern window handles lock with a small key to prevent them from being opened by children or intruders who break the glass. A lost or snapped key leaves the handle locked in position. We replace the handle and issue fresh keys.
Which Window Types Can First Pick Locksmiths Repair?
We repair locks and handles on every window type commonly found in Chorley homes.
uPVC casement windows — by far the most common across Lancashire. We replace espagnolette gearboxes, handles, hinges, friction stays, and keeps.
Timber casement windows — found on older and period properties. We fit traditional casement fasteners, locking stays, and security bolts that preserve the window’s character while enhancing its security.
Sash windows — both traditional cord-and-weight sash windows and modern spring-balance sash windows. We fit sash locks, sash stops, and Brighton fasteners.
Tilt-and-turn windows — common in newer apartments and conversions. The dual-action mechanism is more complex, and faults often leave the window stuck in tilt mode. We repair and replace tilt-and-turn gearboxes and handles.
Aluminum-framed windows — less common but found in some Chorley properties. We carry compatible fittings for the main aluminum window systems.
Does a Broken Window Lock Affect Home Insurance?
It can. Many home insurance policies contain a clause requiring key-operated locks on all accessible windows. “Accessible” usually means any ground-floor window, any window reachable from a flat roof, and any window beside a drainpipe or other climbing aid.
If a break-in occurs through an unlocked window, the insurer may reduce or refuse the claim on the basis that reasonable security was not maintained. The cost of a window lock repair is tiny compared to the cost of an invalidated claim. If you are unsure whether your windows meet your policy’s expectations, we can check during a visit and tell you clearly which windows need attention.
What About Child Safety?
Upstairs windows in children’s rooms present the opposite problem: they need to open for ventilation but must not open wide enough for a child to climb through. Window restrictors — small devices that limit how far the sash can travel — are the standard solution. We fit them alongside any lock repair or as a standalone job.
In homes with young children, the combination of a working lock (for security when the window is shut) and a restrictor (for safety when the window is open) covers both risks at once. It is a pairing we recommend to every family across Chorley.
Why Do Chorley Homeowners Call First Pick Locksmiths for Window Locks?
We diagnose before we replace. Many window lock faults are actually alignment or hinge faults. We check the entire window — the mechanism, hinges, and frame — before deciding what to replace. That means you only pay for the repair that is actually needed.
Parts were carried on the van. The most common espagnolette gearboxes, handles, and hinges are on every van. Most window lock repairs across Chorley are done in a single visit.

How Do We Handle an Urgent Window Problem?
A window stuck open on a ground floor is an urgent matter — it is a security risk and, in winter, a weather problem. We treat these calls as a priority across Chorley and aim to arrive within 30 to 45 minutes. In most cases, we can secure the window on the first visit, even if a replacement part needs to be ordered for a final fix on a second visit.
If a window is stuck open on an upper floor and cannot be reached safely from inside, call us before attempting to close it from the outside. Falls from height cause far worse outcomes than a draughty bedroom.

Frequently Asked Questions about Window Lock Repair Chorley
How can I tell if my window lock needs repairing or replacing?
If the handle turns but nothing engages, the internal gearbox has likely failed and needs to be replaced. If the handle is stiff, floppy, or will not complete a full turn, the handle or its spring is the problem. If the window closes but the lock will not catch, the window may have dropped in its frame. We diagnose the exact cause on arrival.
Can you repair windows that are stuck in the open position?
Yes. We treat this as an urgent call. A stuck-open ground-floor window is a security gap we aim to close within 30 to 45 minutes across Chorley.
Are window lock repairs expensive?
Window lock work is among the most affordable services we offer. A handle swap is a quick, low-cost job. Even a full espagnolette mechanism replacement costs far less than a new window. We confirm the price before starting.
Should I repair one broken window lock or check all the locks?
If one window lock has failed after years of use, the others in the same batch are likely not far behind. We are happy to check every window in the house during the same visit — no extra charge for the inspection.
Do you fit child safety restrictors on windows?
Yes. We supply and fit restrictors for casement and sash windows. They limit how far the window opens while still allowing ventilation. We recommend them for any upstairs window in a home with young children.
