When You Need Window Lock Services
Window hardware in Katy faces unique environmental stressors. Our region experiences high humidity and significant soil movement due to expansive clay, which often causes window frames to shift, warp, or settle unevenly. When a frame shifts even slightly, the locking mechanism may no longer align with the strike plate, leading to jams or failures. You should call us if you notice these specific symptoms:
- Misaligned Latches: The window closes, but the lock does not engage because the latch and the strike plate are no longer flush. This is a common result of foundation settling in older homes across Katy.
- Broken or Missing Sash Locks: The lever or cam lock on a double-hung window has snapped off or the spring inside the mechanism has failed, leaving the window unsecured.
- Jammed Sliding Window Latches: The thumb-turn or sliding latch on a patio-style or horizontal sliding window is stuck, preventing you from opening or locking the window.
- Security Upgrades: You have recently purchased a home in areas like Tamarron or Cane Island and need to replace existing, generic window latches with more robust, pick-resistant hardware from brands like Baldwin, Yale, or Mul-T-Lock.
- Child Safety Restrictions: You need to install window limiters or specialized locks to prevent windows from opening beyond a certain point, a common request for families with young children.
It is important to remember that a window lock is not just a convenience; it is a primary security barrier. If you find yourself struggling to force a lock shut, stop. Forcing hardware often leads to broken glass or damaged frames. Our technicians are trained to assess the condition of the window frame and the lock itself, ensuring the repair is functional and safe.
Our Window Lock Process

At Novak Lock & Security Katy, we follow a documented process to ensure every job is completed to our standards. Daniel Novak has built our reputation on transparency and technical precision. Here is how we manage a window lock service call:
- Initial Assessment and Pricing: When you call (832) 402-8386, our dispatcher will ask for the type of window and the nature of the issue. We provide a firm, written price for the labor and expected parts before we dispatch a technician.
- On-Site Inspection: Our background-checked, uniformed technician arrives at your property in Katy to inspect the window. We verify that the issue is strictly the lock and not a structural problem with the window frame itself.
- Hardware Selection: We work with a wide range of hardware, from standard replacement parts to high-security options like those from Sargent or Mul-T-Lock. If the original manufacturer part is obsolete, we source compatible hardware that maintains the security and aesthetic of your home.
- Installation and Alignment: We install the new lock, ensuring it is properly aligned with the strike plate. We test the operation multiple times to ensure it engages smoothly, even if the window frame has experienced minor settling.
- Documented Photo Record: Upon completion, we provide a documented photo record of the work performed. This is part of our standard procedure, ensuring you have a record of the repair for your home maintenance files.
- The 365-Day Done Right Promise: All our work is backed by our 365-Day Done Right Promise. If the lock does not function as intended, we make it right.

FAQs - Window Lock

Can you match the finish of my existing window hardware?
Yes, we carry a variety of finishes including brushed nickel, oil-rubbed bronze, and white to match the existing hardware on your windows. When you speak with our team, let us know the color and finish you are looking for so we can ensure the technician brings the correct match to your home in Katy.
Is it cheaper to repair or replace a window lock?
In most cases, replacing the lock mechanism is the most cost-effective and secure option, as repair attempts on internal spring-loaded components often fail shortly after. We will evaluate the hardware on-site and provide an honest recommendation based on the condition of the existing lock, including whether a Lock Change is warranted, always adhering to our policy of written pricing before any work begins.
How do I know if my window lock is a security risk?
If you can easily jiggle the window while it is in the locked position, or if the latch does not fully engage with the strike plate, it is a security risk. A lock that does not properly engage is effectively useless against forced entry. If you are concerned about your home’s security, call (832) 402-8386 and we can perform a security assessment of your windows and doors, including Door Reinforcement options.
Do you handle child safety window locks?
Yes, we install window limiters and safety stops that prevent windows from being opened wide enough for a child to fall through, while still allowing for ventilation. These devices are important for homes with young children, and we can install them on almost any style of window. Call us today to discuss your specific safety needs.
If you are ready to secure your windows, call (832) 402-8386. We provide free estimates over the phone and stand by our work with the 365-Day Done Right Promise. Whether you are in the heart of Katy or the surrounding areas, we are ready to assist with your Residential Locksmith services needs.
