Deadbolt Installation in East Whiteland, PA

A back door can feel weak when the knob is its only lock.

A deadbolt adds a separate lock that secures the door to the frame. We install deadbolts on entry doors in East Whiteland, placing the strike so the bolt has room to extend fully rather than stop short. A lock that does not extend all the way may not hold as intended. If you want to use one key for your other locks, matching may be possible when the locks are compatible.

Near glass, a single cylinder has an inside turn that someone could reach through broken glass. You use a key on the outside and turn the lock by hand on the inside. A double cylinder removes that inside turn but needs a key on both sides, which makes it unsuitable for a door needed for exit. We install both styles in East Whiteland, with the choice guided by the door and how you need to use it.

We first look at the door to your garage or basement, checking its thickness, the existing knob lock and the space available for a deadbolt.

We also look at how it meets the frame, since that affects where the bolt needs to enter. You may have a choice between a single cylinder, operated from outside with a key and from inside with a thumb turn, and a double cylinder, which requires a key on both sides. Near glass, the second option limits access through a broken pane, but you would need it to get out.

Before starting, we explain which options fit the opening and whether the new lock can be keyed to match your other locks. Matching requires compatible keyways, so a separate one may be necessary. We position the strike so the bolt extends fully into the frame rather than stopping short or rubbing. With you, we check the action with the door open and closed, then have you try both sides so you know how each works.

A garage or basement entry may be exposed to dust and changes in humidity.

Wipe the lock with a dry cloth, and use only the lubricant recommended by its maker. Keep the key clean and avoid forcing it if it resists turning. For a double cylinder model, keep the inside key in an accessible place known to everyone who uses that exit.

Test the deadbolt with the door open, then close it and turn the bolt until it stops naturally, without pushing or pulling on the door. If it turns freely when open but catches when closed, the strike or the fit may have shifted. Scuff marks near the opening are another sign to watch for. Call us if the lock binds, turning becomes difficult, or the bolt stops short. We can check the alignment and determine what needs adjustment before the problem puts more strain on the mechanism.
