Deadbolt Installation in Woolwich
The front door has a handsome lever and a keyed knob, and that is all.
In plain words
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 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


Which key should open it
A deadbolt is also a key decision, so the locksmith asks how the household's keys are arranged now. If every door shares one key, the new cylinder can be pinned to that same key, provided the keyways match, so nobody's ring grows. If the house has just changed hands, this is the natural time to set the new bolt and the other exterior locks to a fresh key and retire whatever copies are out there. Restricted or high-security keyways, keypad models with a backup cylinder and locks that must match a rental building's system all steer the choice of hardware, and it is easier to settle this before the box is opened than after.
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.
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
Strike 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.
Grade and type of deadbolt
A builder-grade bolt, a residential model with a high security grade, and a heavy commercial-pattern deadbolt sit at different points in the hardware part of the quote, and the locksmith explains the differences.
Removing 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.
What to have ready
- Do you want the new deadbolt to work on the same key as your other doors?
- Do you own the home, rent it, or manage it for someone else?
- Which doors do you want a deadbolt on, and does each one already have a bolt or only a knob?
Deadbolt Installation: questions
QuestionsDo I need a deadbolt on the door from the garage into the house?
It is worth having. The door between an attached garage and the living space is in practice often the softest way in, since a garage door left open leaves a passage knob as the only barrier. A thumb-turn deadbolt there costs a few minutes a day and closes that gap.
I just moved in. Should the new deadbolt be keyed to a new key?
It is a good moment for it. Nobody knows how many copies of a previous owner's key exist, so pinning the new bolt, and the rest of the exterior doors, to one fresh key retires all of them at once. Lock manufacturers list a move as one of the main reasons to rekey. You come away with a known number of keys, each tested in every door it is meant to open.
How do I look after a deadbolt once it is installed?
Very little is needed. Each spring and autumn, lock the door from inside and feel whether the bolt still goes home without the door being pulled; if it hesitates, the door has moved with the season and a small strike adjustment restores it. Whatever lubricant the lock's own maker specifies keeps it smooth, often a dry PTFE or graphite type in the keyway and along the bolt, though some cylinders are meant to be serviced with oil. In winter, wipe road salt off the outside trim to protect the finish.
