What We Offer

Sash-lock matching

Measure screw spacing, cam reach, keeper height, and mounting orientation.

Casement diagnosis

Distinguish the locking mechanism from the crank operator and hinges.

Slider hardware

Check latch engagement and alignment rather than assuming the hook alone has failed.

Older windows

Assess matching replacement options and any historic-property requirements.

Window Lock Repair in Washington DC

A window that does not lock may need a small hardware repair or attention to the sash and frame. Identify the failed component before ordering a replacement.

Diagnose the system

On a double-hung window, inspect both the cam lock and keeper and confirm the sashes meet correctly. On a casement, the crank operator and locking linkage perform different jobs. On a slider, check the latch position and panel alignment. A replacement latch will not correct every roller, frame, or hinge problem.

Record the window maker and model where available, then measure the mounting and engagement dimensions. A universal part should only be used where it is genuinely compatible. Availability of older parts and matching finishes must be confirmed.

Retain the right function

Avoid altering glazing pockets, weather seals, or drainage. Required emergency escape must remain usable after work. If the window cannot be repaired safely, discuss the scope for a window specialist rather than promising that any mechanism can be rebuilt.

See secondary window-lock installation where an additional compatible device is useful, and home security assessment for a review of other accessible openings.

Hardware Comparison

Rekeying and Replacement: Different Decisions

Question	Rekey Existing Hardware	Replace Hardware
Main purpose	Change which key operates a compatible cylinder	Change the lock, its condition, or its function
Existing condition	Lock and door should be working properly	Assess wear, damage, fit, and needed repairs
Compatibility	Depends on the cylinder and key system	Depends on door preparation and selected model
Exit operation	Confirm the current inside operation remains suitable	Confirm the proposed function and applicable exit requirements

Select hardware for the actual opening. A key-operated inside lock can restrict exit and needs particular care; do not assume a glass panel makes it appropriate.

Common Questions

Window Lock Service in Washington DC FAQs

The lock turns but the window opens. Why?

The cam may miss the keeper, a component may be broken, or the sash may be misaligned. The cause needs inspection before selecting a larger keeper or replacement lock.

Do I need an entire new window?

Not always. A compatible hardware repair may be possible. Damaged glazing, frames, balances, or unsupported mechanisms may need a window specialist.

Are universal window locks always suitable?

No. Match the window construction, dimensions, operation, and permitted mounting. A visually similar part can prevent full closing or damage the sash.

What information helps when booking residential locksmith work?

Describe the door and lock, the problem, the Washington DC address, and whether access is affected now. Photos of visible hardware can help identify the next step.

Should I rekey or replace a lock?

Rekeying may suit a compatible lock that works properly when the aim is to change who has a key. Damage, wear, incompatible hardware, or a different function may make replacement more appropriate.

What should I check before buying a replacement lock?

Check the door thickness, existing preparation, lock function, and the manufacturer’s installation requirements. Shared entrances and rental properties may also have owner or building requirements.

Can an arrival time or full price be confirmed from a photo?

A photo can clarify visible hardware, but it may not show internal damage or door and frame conditions. Ask whether an assessment is needed, what it costs, and how the final scope and price will be approved.

What if I am locked out right now?

Call (202) 830-0706 to explain the location and check current availability. If anyone is in immediate danger or there is a medical emergency, call 911 first.

What authorization should I prepare?

Have identification and evidence that you own, occupy, or manage the property. For a shared or rental building, involve the person authorized to approve the work.

Before Work Starts on Your Home

Confirm who may authorize the work, which doors are included, and whether existing keys should stop working. Keep a written record of the hardware and keys supplied.
