A properly installed deadbolt is the backbone of door security. Unlike spring-latch knob locks, which can be slipped with a credit card, a deadbolt throws a solid bolt deep into the frame and stays put. We install single-cylinder, double-cylinder, and jimmy-proof deadbolts on wood and metal doors.
Installation quality matters more than the lock's price tag. We bore the door cleanly, seat the bolt housing squarely, and — critically — reinforce the strike side with long screws into the framing and a heavy-duty strike plate. A deadbolt is only as strong as what it bolts into.
For New York apartments, the classic surface-mounted jimmy-proof deadbolt remains one of the most effective options: it resists kicking, prying, and shimming, and it works on doors where a standard bored deadbolt won't fit.
We bring deadbolt installation to every neighborhood we serve. Local guides:
A regular knob lock uses a spring-loaded latch that can be forced back. A deadbolt extends a solid metal bolt into the door frame that can't be pushed back — it must be turned with the key or thumbturn.
Double-cylinder (keyed both sides) helps near glass panels but can slow emergency exit. We'll discuss your door layout and recommend the safer option for your situation.
Yes. Metal doors need the right bits and technique, which we bring. The result is just as solid as on wood.
