Deadbolt Installation in Niagara Falls
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
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 goes
Exit, fire and who lives here
The last part of the first look is about the people, not the door. The locksmith asks whether this is the door the household leaves through, whether children, older relatives or anyone with limited hand strength use it, and whether it is a rental where the landlord holds keys. A door that serves as a way out gets a thumb-turn planned for it, so nobody has to hunt for a key to leave. A lever thumb-turn is easier for small or stiff hands than a knurled one, and a rental may need a note to the building manager. None of this takes long, and it shapes which box comes off the van.
Fitting the bolt and setting the backset
The bolt assembly slides into the edge bore with the faceplate set the way its maker marks, commonly the word "top" facing up. Most residential bolts adjust between 60 mm and 70 mm by twisting or sliding the faceplate, and the locksmith sets it to the backset measured earlier so the tailpiece from the cylinder lands in the centre of the bolt's cam. The bolt is secured with its two short screws, and the locksmith works it in and out by hand to feel that it runs freely through the door without rubbing on the bore. On an insulated door a round drive-in collar may replace the flat plate where the edge is too thin to mortise.
A record for the home file
You should know what is on your door in plain terms, so the visit closes with a short account: the model and grade of deadbolt fitted, its finish, the backset and bore it sits in, whether the cylinder was keyed alike or set to a new key, how many keys were cut, and what was done on the frame side. For a rental, this note is useful for the landlord or building manager, who under tenancy rules is entitled to know what lock is on the unit and to hold a key. For an owner it is one line in the house file that makes the next locksmith visit, whenever it comes, a simpler conversation.

What affects the quote
Same fees day, night or weekend
1Removing and disposing of the old hardware
Some visits end with the old deadbolt and strike left with the homeowner, and others ask for it to be removed and hauled away. Taking the old hardware away adds a small amount of time and is agreed before the new deadbolt goes in.
2Travel to the property
Distance and access are part of any call-out: a house on a suburban street and a rural property down a long road involve different driving time, and the quote says so.
3Strike and frame reinforcement
A reinforced strike with long screws is standard; a full-length jamb reinforcer, a strike box or repairs to a split jamb after a forced entry are extra items quoted on their own.
Deadbolt Installation: questions
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.
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.
What do lock grades mean when I am picking a deadbolt?
Residential deadbolts are graded under an industry standard in three categories, security, durability and finish, with letter grades from C through A, so a lock marked with three A grades has met the highest level in each. Heavier commercial-pattern bolts are graded 1, 2 or 3, with 1 the highest. The grades let you match hardware to a busy family door or an exposed side entrance without relying on the weight of the box.
