A House Has More Openings Than Doors
Count them honestly. A typical Belsize Park house has two or three doors and perhaps eighteen windows. Yet almost every conversation about security stops at the doors, because that is what people picture when they picture a lock.
Windows here deserve better. Sashes run in boxes built well over a century ago, and the original catch was designed to stop rattling rather than anybody climbing through. Lower ground floors sit below pavement level, hidden from the street. Meanwhile side returns give quiet access to whole runs of glass.
None of that means ripping anything out. Sympathetic hardware exists and it works. So this page runs through what actually helps. Our engineers reach NW3 in twenty-five to forty minutes. Ring 020 7129 7496.

24 Hour Emergency Locksmith Callouts in NW3
Below are the jobs that bring us up the hill most often. Quite a few of them involve glass rather than a doorway.
Sash pushed up from outside
The old catch gave way. We can make it secure tonight and fit something proper afterwards.
Dispatched firstShut out of the house
The ordinary lockout, opened without damage wherever the door allows.
25–40 minCasement stay or handle snapped
Now the window will not close, which matters far more in winter than people first assume.
Same dayKey broken in a period lock
Old mortice locks and old keys wear together. Extraction first, then a sensible conversation.
25–40 minGarden door glass broken
Boarded and made secure tonight, with the glazing arranged once you have spoken to your insurer.
Dispatched firstSomething worth saying about period property. Original joinery can be repaired far more often than it gets replaced, so we look before reaching for anything drastic. Where a window genuinely cannot be made secure as it stands, we say that plainly instead of fitting hardware that will not hold.

Locked out locksmith NW3
Locked Out in Hampstead? Please Do Not Climb Anything
Hills, basement steps and old railings make this a bad place for improvised entry. People fall. Every year somebody in a district like this ends up in hospital rather than merely inconvenienced, and the door still needs opening afterwards.
Instead, check the obvious routes calmly. A back door, a garden room, a lower ground entrance, or a neighbour holding a spare set. Households here often leave keys with somebody nearby, so two calls may end the problem.
Avoid forcing a sash. It feels like the soft option compared with a door, though the box frame splits and the cords part. Repairing a damaged sash costs considerably more than opening a front door, and it takes far longer to arrange.

Searching Locksmith Near Me in NW3? Ask About Period Work
Plenty of firms handle modern doors competently and then meet a hundred year old sash window. So the useful question is whether they work on period joinery regularly, and what they would do if the timber is soft.
Also ask what happens when hardware cannot be fitted without damage. A firm that will tell you no is worth more than one that fits something anyway. Get the total on the phone either way, including any evening rate.
Do you work on sash windows?Yes, regularly. We fit locks that suit the box frame rather than fighting it.
Where do you come from?37 Holloway Road, N7. Twenty-five to forty minutes across to Hampstead.
Will you say if something cannot be done?Yes. Soft timber will not hold a lock, and we would rather tell you.
Is the price agreed before travel?Yes, evening rates included, with nothing added at the door.
Every opening, not only the door
Five Openings That Get Overlooked in NW3 Homes
Work round the outside of the building once. These five come up again and again across the district, in houses and flats alike.
Sash Windows Within Reach of the Ground
The original catch holds the two sashes together and stops them rattling. It was never a security device. Dual screws or sash stops change that, and both can be fitted discreetly into the meeting rail. Since they are small and reversible, they suit period windows far better than anything bolted across the face.
Door lock fitting →Lower Ground Floors Nobody Can See
Basement windows sit in a lightwell below the pavement, screened by railings and often unlit. Somebody working there is invisible within seconds. Therefore these openings justify more than the rest of the house. Grilles are one answer, although any bedroom below ground must still allow escape.
Security grilles →Fanlights and Small High Openings
A little window above a door or on a half landing looks too small to matter. Frequently it is not, and it is left open all summer because nobody thinks of it. Fit a restrictor and treat it like any other opening. Ventilation still works, which is usually why it was open in the first place.
Lock replacement →The Garden Door Beside the Kitchen
Half glazed, in daily use and fitted with whatever was cheapest at the time. Because it opens onto a garden that nobody overlooks, it deserves the same hardware as the front. Where glass sits beside the handle, discuss what happens if somebody reaches through, and keep escape workable.
Patio doors →Roof Terraces and Flat Roof Access
Conversions here often have a terrace, a dormer or a door onto a flat roof. Those routes connect to neighbouring buildings more often than owners realise. Walk out and look back at your own property from there. Whatever you can reach, somebody else can reach too.

Locksmith NW3 – Frequently Asked Questions
Sash and casement windows
What actually secures a sash window?
A dual screw through the meeting rail, or a pair of sash stops that allow ventilation while limiting how far the window opens. Both are small, discreet and reversible. The original catch was never intended to resist anybody, so it should not be relied upon.
Can windows be locked without spoiling the look?
Usually, yes. Most of the hardware that works here is tiny and sits in the meeting rail or the frame edge. We choose fittings that suit the age of the joinery rather than bolting something obvious across the face of the glass.
My window frames feel soft. Does that matter?
It matters a great deal. A lock is only as strong as the timber holding the screws, so soft or wet wood gives way immediately. Where we find that, we will tell you rather than fitting something that looks right and fails.
How quickly can you reach Hampstead?
Twenty-five to forty minutes from Holloway Road. The hill and the parking take longer than the driving on some days, and we allow for both when quoting.
Lower ground floors and grilles
Are grilles worth fitting over basement windows?
They help considerably, because a lightwell hides somebody completely. The important condition is escape. Any room used for sleeping needs a way out, so we fit hinged and releasable grilles rather than anything permanently fixed.
Would a grille look wrong on a period house?
Not necessarily. Simple vertical bars in a lightwell are common and largely unseen from the street. Where your building carries planning protection, check with the council's conservation team before committing to anything visible.
Doors in older buildings
Can you change a lock without damaging an original door?
In most cases we swap the cylinder or the internal parts and leave the visible ironmongery alone. Older mortice locks can often be serviced rather than replaced. We look first and explain the options before cutting anything.
My front door key has worn smooth. What now?
Worn keys and worn locks fail together, usually at the least convenient moment. Cutting a fresh key from the original pattern often solves it. Where the lock itself has worn internally, that will keep happening until the lock is dealt with.
Do you fit locks that need a key on both sides?
Occasionally, where glass sits beside the handle. Escape has to come first though, so the key must live somewhere reachable and everybody in the house must know where. We talk it through rather than simply fitting one.
Terraces, roofs and outside space
Is a roof terrace really a risk?
It can be, particularly where terraces run close together or a flat roof links buildings. Stand on yours and look at what is reachable. Anything you could step across, somebody else could step across as well.
What about a door from the garden into the lower ground floor?
Treat it as a main entrance, because that is exactly what it is. It is usually the least visible door on the property, so it deserves proper hardware rather than the builder's original fitting.
Should outdoor lighting cover the side of the house?
Yes, and it is one of the cheapest improvements available. A sensor light on the side path removes the quiet route. Aim it downwards so it lights your own ground rather than the neighbours' bedrooms.
Do window restrictors help with young children as well?
Yes, and many households fit them for that reason first. A restrictor limits how far the sash or casement opens while still allowing air through. Choose a type an adult can release quickly, because escape from an upper floor still has to be possible.
