Deadbolt Installation in Swansea
The back door has a deadbolt in name only: a short bolt, a thin brass strike held by two little screws, and a jamb you can flex with your palm. It was fine for a builder's showing.
Deadbolt Installation
In plain words
Most of the value in a deadbolt is on the frame side, which is why a good installation spends as much time on the jamb as on the door. The bolt is only as strong as the pocket it throws into and the screws that hold the strike. Short screws in a standard strike bite only into the thin jamb board; a reinforced strike fastened with 75 mm screws passes through that board into the stud behind, so a blow against the door meets the house rather than a strip of pine. The pocket is cut deep enough for a full throw and aligned so the bolt slides home freely.
How the visit goesThe old deadbolt has grown lazy. You turn the thumb-turn and the bolt creeps out halfway, then needs a second push with the door pulled tight. Some mornings the key has to be jiggled before it will come back out.

How the visit goes
What the door is made of
The first thing the locksmith reads is the door itself, because it decides how the holes get cut. A solid wood slab in a century home bores cleanly but can split at the edge if the mortise is rushed. A steel-clad insulated door has a thin metal skin over foam, sometimes with a wood block at lock height, and needs a metal-cutting hole saw run slowly. Fibreglass behaves like a hard plastic and chips if the bit grabs. Thickness matters too: most exterior doors are 44 mm, some older ones 35 mm, and the deadbolt's screws and collar have to suit that. Ten seconds with a tape and a knuckle on the face answer all of this.
Swapping an old deadbolt in place
When an existing bolt is being replaced, the work starts by backing out the two inside screws and lifting off both housings, then removing the bolt from the edge. The bore and backset are measured against the new hardware, and any difference is dealt with before the new bolt goes in: a larger bore for a smart deadbolt, a different faceplate shape, or a spacer for a thinner door. The new bolt, cylinder and thumb-turn go on in the usual order. The old strike comes off too, the pocket is deepened if needed, and a reinforced strike with long screws replaces it, so the upgrade happens on both sides of the gap.
Ready for a smart lock later
Because the door was prepared to the standard bore and backset, it suits many future options, though the model chosen later still sets its own bore, backset and thickness requirements. Keypad and app-controlled deadbolts fit the same 54 mm cross bore and the same edge bore as the mechanical lock fitted today, so upgrading later means swapping the hardware, not cutting the door again. The backset and bore measurements are written on the packaging left with you. If you want to think about a keypad down the road, ask the locksmith which models suit the door thickness and whether a backup keyed cylinder is worth having for the one day the batteries are flat.

What affects the quote
Same fees day, night or weekend
1Door material
Solid wood, steel-clad and fibreglass doors are each cut differently. Metal skins call for slower cutting and cleanup of filings, so the material is one of the first things a quote takes into account.
2Storm door or restricted clearance
A tight storm door, a narrow lock stile or a decorative panel at bolt height can require low-profile trim or a shifted position, which is settled and quoted at the assessment.
3Finish and trim style
Coated finishes built for salt and sun, matching trim for an existing handleset, and low-profile faces cost differently from a standard brass or nickel unit, and you choose the level.
Deadbolt Installation: questions
I rent. Can I have a deadbolt installed on my unit door?
You can, with a conversation first. Tenancy rules in this province expect a tenant to have the landlord's consent before changing locks and expect the landlord to hold a key, so ask in writing and share the plan. Many landlords welcome a proper bolt. The locksmith can key the new cylinder to the building's existing key where the keyway allows, and leave a note of the model and keys cut for the building manager.
What about glass beside the door or a window in it?
Glass within reach of the lock is the one case where a plain thumb-turn deserves thought. Options include a captive thumb-turn that turns freely until you remove its small key, laminated glass or a tested security-film system with its specified frame attachment, or simply setting the bolt farther from the glass. Lock manufacturers describe sidelights as a weak point, so the locksmith measures the reach and lays out the choices rather than defaulting to a key on the inside.
The door has to be pulled before the old bolt will lock. Will a new one fix that?
The new bolt will only lock as smoothly as the door and frame let it, so the locksmith deals with the cause as part of the installation. A door that has sagged on loose hinges gets longer hinge screws or a shim, thick weatherstrip is trimmed, and the strike is set from the bolt's actual position with the door closed. The pocket is bored deep enough for a full throw. Afterwards the bolt should slide with fingertip effort.
