Why Deadbolt Installation Is About More Than Just the Lock
A deadbolt's security value lives in the whole system — the cylinder grade, the throw length, the strike plate, the depth of the wood screws anchoring it to the rough framing behind the jamb. Many homeowners in the Great Bridge and Deep Creek neighborhoods discover this the hard way: a single-cylinder deadbolt installed with half-inch screws into a hollow door frame offers almost no resistance to a determined kick. Our technicians evaluate every element — door material, hinge strength, frame integrity, and whether an existing bore hole is correctly sized — before recommending the right hardware. That means the lock you pay for actually performs the way the manufacturer intended.
Terminology matters here, too. A deadbolt is not the same as a spring latch; it requires a deliberate turn of the key or thumb-turn to extend and retract the bolt, which is why it resists forced entry far better. A single-cylinder deadbolt uses a key outside and a thumb-turn inside. A double-cylinder model requires a key on both sides — useful on doors with adjacent glass panels but subject to Virginia fire-egress considerations our technicians will walk you through. A jimmy proof deadbolt installation, sometimes called a rim deadbolt, attaches to the surface of the door rather than boring through it and interlocks with a strike on the door frame, making prying extremely difficult — a popular choice on older Chesapeake rowhouse-style doors where reaming a new bore hole would weaken the door panel.
