Deadbolt Installation in Linwood
Someone tried the door last winter. The frame took it, but the strike plate is bent, one screw hole is stripped, and the bolt sits in the pocket at a slight angle.
Deadbolt Installation
In plain words
Steel-clad and fibreglass doors, the common insulated entry doors in newer subdivisions, take a deadbolt happily as long as they are cut for it properly. The skin is thin metal or resin over a foam core, often with a wood block at lock height, so the cross bore is made with a hole saw suited to the skin, at low speed, and the edge is finished with a plate rather than a chisel mortise. Solid wood doors in older homes are cut conventionally, with care for splitting at the edge. The locksmith reads the door before drilling and picks the method that leaves a clean opening and a true-running bolt.
How the visit goesThe front door has a handsome lever and a keyed knob, and that is all. Nothing above it. When the door is shut, the only thing keeping it closed is a spring latch the width of a thumbnail, and you have started to notice.

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.
A frame that now holds the bolt
Behind the new strike plate is the part of the job you cannot see and will never need to think about. The pocket has been bored deep enough for the bolt to seat fully, the plate has been let into the jamb so it sits flush, and the long screws reach through the jamb into the framing behind it. On a door that had been forced or had stripped screw holes, a full-length reinforcer may sit under the strike. If you press the jamb with your palm now, it does not flex. That stiffness is what a bolt needs to do its work, and it is the reason the installation took as long on the frame as on the door.

What affects the quote
Same fees day, night or weekend
1Non-standard bore or backset
Older doors with a small cross bore, an unusual backset or a mortise lock case need adapting or filling before a modern deadbolt fits, and that preparation is quoted before work begins.
2Door and hinge corrections
A sagging door, loose hinge screws or thick weatherstrip are put right before a bolt is fitted, and that adjustment is quoted as its own line rather than folded into the lock.
3Hardware supplied by you or by the locksmith
If you have already bought the lock, the quote covers labour and any adaptation of the door to that kit. Hardware supplied from the van is listed separately with its grade and finish.
Deadbolt Installation: questions
What do backset and bore mean, and why does the locksmith ask?
Two measurements decide whether a deadbolt fits your door. Bore is the diameter of the big hole through the face, 54 mm on most current hardware. Backset is how far the centre of that hole sits from the door's edge, 60 mm or 70 mm on nearly all residential doors. A replacement must match both to use the existing holes, and a fresh installation is cut to match the knob below, so knowing them ahead puts the right hardware on the van.
Will drilling a new deadbolt damage my steel or fibreglass door?
Not when it is done for that door. Steel-clad doors are cut with a fine-toothed hole saw run slowly through the skin, guided by a jig so the saw cannot skate on the smooth face, and finished from both sides so each skin stays clean. Fibreglass is scored first so the surface does not chip. Shavings are vacuumed from the foam core, and the edge is finished with a collar or plate suited to the stile inside.
Can a deadbolt be added to a door that only has a knob?
Yes, on nearly any wood, steel-clad or fibreglass entry door. The locksmith marks a spot above the knob, clamps a jig to the door and bores a cross hole through the face and a smaller hole through the edge, then cuts a pocket and fits a strike on the frame. The main things checked first are the door's thickness, what is inside it at that height and whether glass sits close by.
