What We Offer

Window identification

Record the manufacturer, sash type, frame material, and existing locking system.

Compatible secondary locks

Evaluate approved pins, sash locks, or track devices for the particular window.

Escape operation

Do not add keyed or obstructive hardware to a required escape opening without confirming the applicable requirements.

Fall-prevention distinction

A ventilation stop or burglar-resistant lock is not automatically a child fall-prevention device.

Secondary Window Locks in Washington DC

Start by restoring the window’s intended operation. A sash that is misaligned or cannot close properly should not be secured by forcing an aftermarket lock into place.

Choose by window construction

Double-hung, casement, hopper, and sliding windows use different hardware. Identify permitted mounting positions and avoid glass, insulated-glass seals, drainage paths, and moving mechanisms. A deep fixing into an unknown frame is not a safe universal installation method.

Additional pins or track devices may restrict opening, but they must be compatible with the window and its required use. A vent position is not a promise of burglary resistance. Nor is ordinary security hardware necessarily tested for child fall prevention.

Preserve emergency escape

The CPSC window-fall guidance discusses guards, stops, and escape considerations. Where a window is a required emergency escape and rescue opening, added hardware must not obstruct its required operation. Do not recommend keyed locks or high, inaccessible releases simply because they make access harder.

For damaged original hardware, see window-lock repair. Review nearby patio doors through sliding-door lock service.

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 Security Installation in Washington DC FAQs

Are factory window locks only for weather sealing?

No. Functions and performance vary by window system. Assess the actual hardware and condition rather than assuming every factory latch is inadequate.

Is a four-inch opening guaranteed safe?

No. CPSC window-fall guidance and the requirements for the opening should inform device selection. A restricted opening is not a guarantee against falls or intrusion.

Can any frame be drilled for a pin?

No. Glazing pockets, reinforcement, balances, seals, and drainage can be damaged. Use a compatible product and the window manufacturer instructions.

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.
