Why a quality deadbolt matters
The deadbolt is your door's primary defence against being kicked or forced open. Unlike a spring latch, a properly thrown deadbolt is a solid steel bar seated deep in the frame. But not all deadbolts are equal — grade, throw length, and especially how it's installed all determine whether it holds under attack.
We fit deadbolts rated for real security and install them so the bolt throws fully into a reinforced strike. Most break-ins in residential areas exploit weak or poorly installed locks; a good deadbolt, fitted correctly, removes that easy opportunity and makes your Newmarket home a far less appealing target.
It's the installation that stops a kick
Here's what many people don't realise: a door usually fails at the frame, not the lock. When a strike plate is held by short screws that only grip the thin door trim, even a strong deadbolt pops out under a single kick. The fix is simple and inexpensive — a heavy-duty strike plate fixed with long screws that reach into the wall framing behind the jamb.
We reinforce the strike on every deadbolt we install, so the force of an attack is transferred into the building structure rather than splintering the trim. It's a small detail that makes a dramatic difference to how much your door can withstand.
Single, double and keypad deadbolts
We help you choose the right type for each door. Single-cylinder deadbolts (key outside, thumb-turn inside) suit most doors. Double-cylinder deadbolts (key both sides) add security for doors with glass nearby, though we'll explain the safety trade-offs for emergency exit. Keypad deadbolts give you keyless convenience with the holding strength of a deadbolt.
Whatever you choose, we install trusted brands so spare keys and parts stay easy to source, and we make sure the new deadbolt operates smoothly without forcing.
Deadbolts for businesses too
Commercial doors benefit from quality deadbolts and reinforcement just as much as homes, particularly back doors and storerooms that aren't watched during the day. We install commercial-grade deadbolts that handle heavy use and complement your other security measures, while keeping safe, code-compliant exit in mind.

Frequently Asked Questions
How much does deadbolt installation cost in Newmarket?
It depends on the deadbolt you choose and whether a new hole needs to be bored in the door. A standard single-cylinder deadbolt installation is affordable, while keypad or high-security deadbolts cost more because of the hardware. We include reinforced strike plates as standard and confirm the full price before we start, with no hidden fees.
Single-cylinder or double-cylinder deadbolt — which is better?
Single-cylinder deadbolts (key outside, thumb-turn inside) are right for most doors and allow quick exit in an emergency. Double-cylinder deadbolts (key both sides) add security where there's glass near the lock that could be broken to reach a thumb-turn, but they require a key to exit, which is a safety consideration during a fire. We'll explain the trade-offs and help you choose what's safest for your door.
Will a new deadbolt really stop a break-in?
A quality deadbolt that's installed correctly makes a big difference, because most forced entries exploit weak or poorly fitted locks. The key is reinforcement: we fit a heavy-duty strike plate with long screws that anchor into the wall framing, so a kick is absorbed by the structure instead of splitting the door trim. The lock and the reinforcement together are what resist an attack.
Can you add a deadbolt to a door that doesn't have one?
Yes. We can bore and fit a new deadbolt on most doors that currently only have a knob or lever latch, adding a major layer of security. We'll check that your door and frame are suitable, choose the right deadbolt, and reinforce the strike so the finished installation is genuinely secure.
Do you install keypad deadbolts?
Yes. Keypad deadbolts give you keyless entry with the holding strength of a deadbolt — no more hiding spare keys. We install and configure reliable, well-supported models, set up your codes, and show you how to add or remove them. We'll also confirm your door is suitable before installation.
