In Depth
Precision Craftsmanship for Your Living Spaces
French interior doors are a classic architectural feature in many Washington DC residences, from defining a formal dining room in a historic rowhouse to closing off a modern home office in a new condo. Unlike standard single passage doors, double doors require absolute millimeter precision. If the frame is slightly out of plumb, the doors will hang unevenly, bind together, or fail to latch.
DC Local Locksmith merges the technical precision of our locksmithing background with expert door alignment. Our licensed, bonded, and insured technicians are masters of interior door geometry, offering exact, transparent over-the-phone quotes and precise execution.
The Mechanics of Perfect Alignment
A successful interior French door installation requires obsessive attention to the framing and hinges:
- Plumb and Level Framing: Older homes in DC are notorious for floors and walls that have settled over the decades. Our technicians skillfully shim the rough opening to establish a perfectly plumb door jamb, the critical foundation for double doors.
- Hinge Sizing and Routing: French doors containing multiple panes of glass are surprisingly heavy. We cleanly route hinge mortises and install correctly load-rated hinges to ensure the doors do not slowly sag over time.
- Equal Sightlines: We adjust the door gaps carefully until the vertical reveal between the two doors is perfectly uniform from the header to the floor.
Specialized Interior Hardware
Interior French doors typically do not require high-security deadbolts, but they do require specific hardware to function correctly and look beautiful:
- Ball and Roller Catches: To hold the doors shut without requiring the turn of a knob, we install high-tension ball catches mortised into the top edge of the door, aligning perfectly with the header strike.
- Dummy and Passage Levers: We install premium architectural hardware. A stationary (dummy) knob on the inactive side mirrors the operating knob on the active side for perfect aesthetic symmetry.
- Privacy Integrations: For home offices or master suites separated by French doors, we install surface-mounted slide bolts on the inactive door, combined with a privacy latch mechanism on the active door, granting solitude without sacrificing style.
For initial installation, hardware upgrades, or adjustments to dragging and binding interior double doors, rely on the professionals at DC Local Locksmith. Our dedicated technicians bring high-end craftsmanship directly to your floorplan.

Frequently Asked Questions
My interior French doors rub together in the middle. Can you fix that?
Yes, this is a common issue caused by structural settling or worn hinges. We re-hang, shim, and adjust the doors to restore a perfect, even clearance down the middle.
What kind of latches do interior French doors use?
Most interior double doors utilize top-mounted ball catches or roller catches to keep the doors closed, while standard passage knobs or dummy levers provide the aesthetic hardware.
Can you install privacy locks on interior French doors?
Yes. If your French doors lead to a home office or bedroom, we can install specialized mortise privacy bolts or surface-mounted slide bolts for secure privacy.
