Deadbolt Installation
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.

The right deadbolt for a door depends on how the door is used and where it sits. A front door that a family goes through twenty times a day needs a durable mechanism and a finish that shrugs off salt spray and sun; a side door in a laneway wants a heavy bolt and a strike that reaches the framing. Residential deadbolts carry letter grades for security, durability and finish, and heavier commercial-pattern bolts carry numbered grades, so there is a plain way to compare. The locksmith talks through those options, then fits the one you choose with the same care whichever grade it is.
How the visit goesThe door from the garage into the kitchen closes on a passage knob with no lock at all. Anyone who opens the garage is one turn of a handle from the house, and the insurance renewal form has a question about exactly that.
Deadbolt Installation · St. Catharines
How the visit goes

- 1
Measuring the bore and the backset
Deadbolts are built around two dimensions. The cross bore is the large hole through the face of the door, 54 mm on most residential hardware, though some older or imported locks used 38 mm. The backset is the distance from the door edge to the centre of that hole, 60 mm or 70 mm on nearly every door in this part of the world. If a deadbolt is being replaced, both are measured so the new lock lands in the existing holes without a shim or a gap. On a new installation they are chosen to match the knob below, so the two locks line up and any future keypad or smart deadbolt drops straight in.

Working on a steel-clad or fibreglass door
Insulated doors are cut with the skin in mind. A hole saw with fine teeth is run at low speed through the metal face, with the jig doing the steering so the saw does not skate on the smooth surface, and the cut is finished from the second face to keep both skins clean. Swarf is vacuumed out of the core so it cannot work into the bolt. The edge is usually a wood or composite stile inside a folded metal lip, and the bolt is finished with a drive-in collar or a plate screwed into the stile rather than a chiselled mortise. Fibreglass is scored first so the skin does not chip, then cut the same way.

Looking after it through the seasons
A deadbolt asks for very little, and most of it happens twice a year. In spring and again in autumn, throw the bolt with the door closed and notice whether it still slides in freely; wood doors swell in humid summers and shrink in dry winter air, and the first sign is a bolt that needs the door pulled before it will lock. If so, a small strike adjustment puts it right. Give the bolt and keyway a puff of whatever lubricant the lock's own maker specifies, often dry PTFE or graphite, since some cylinders are serviced with oil instead. Wipe salt off the outside trim after a slushy week so the finish stays bright.

What affects the quote
- 1
Door 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.
- 2
Finish 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.
- 3
Non-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.

Deadbolt Installation: questions
How high above the knob does the deadbolt go?
The usual position is 140 to 150 mm above the centre of the knob, which lines the two locks up and keeps both within one reach. Manufacturers' templates assume that spacing, which helps a later keypad or handleset line up, though many handlesets still need their own lower hole drilled to that model's template. The height is nudged if it would land on glass, a decorative panel or a hollow spot inside an insulated door, and to make sure the frame behind it is solid.
Can the new deadbolt use the same key as my other doors?
Usually, yes. If the new lock shares a keyway with your existing cylinders, the locksmith repins it on the bench so your current key operates it, and nothing changes on anyone's ring. If the keyways differ, the other doors can be brought onto the new key instead. Say which key you want to keep before the hardware is chosen, because keyway is part of picking the lock.
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.

What the census means at the door
71%
Older homes. About 71% of homes in St. Catharines were built in 1980 or earlier, according to the 2021 Census.
Basement and side entries on older homes were often fitted long after the house was built, with whatever lock was on hand. Bringing those doors up to the standard of the front entry, and onto the same key, is a common and satisfying job.
56%
A mix of homes. Single-detached houses make up about 56% of homes in St. Catharines (2021 Census).
Mixed housing means a locksmith sees a bungalow in the morning and a condo tower in the afternoon. The stocked van has house-door deadbolts, suite-door cylinders and the finishes for each, so neither kind of customer waits for a second visit.
