How it works
Remove old hardware
We unscrew and remove the existing knob or deadbolt, checking the door edge and bore holes for damage.
Install and align
We fit the new hardware, make sure the latch and bolt throw fully and align the strike plate for a secure catch.
Test and hand over
We test the lock from both sides, confirm smooth operation and hand you the keys.
Problems we fix
- Strike plate holes elongated from years of door movement, making the bolt fall short
- Wrong backset measurement chosen at the hardware store, so the new knob won't fit
- Deadbolts installed without reinforcing the strike plate, making the door easy to kick in
- Interior knobs that turn freely without retracting the latch because the spindle is stripped
Doorknob & Lock Replacement in Charleston — FAQ
Can you re-key the lock so I don't need to replace the whole unit?
Yes. Re-keying changes only the cylinder pins, so the lock works with a new key while keeping the existing hardware. It's much cheaper than full replacement.
Do I need a separate deadbolt and knob, or can I use just one?
Exterior doors should always have both — a knob or lever for the latch and a deadbolt for security. A knob latch alone is easy to bypass.
Can you install a smart lock?
Yes. We install most keypad and app-connected smart locks, set up the strike alignment and walk you through the programming.
Doorknob & Lock Replacement across Charleston
Charleston's humid subtropical climate, salt air and active storm season are tough on homes — swollen doors, rusting hardware, mildew-prone caulk and storm-loosened trim are all common. Downtown's historic houses add original plaster walls and tight, detailed millwork, while West Ashley and the islands bring newer builds with their own quirks. Our pros are comfortable with both.
