If a window handle is broken, prioritize securing the window to prevent accidental openings or damage. Use a temporary barrier like tape or a wooden stick to block the sliding track. Contact a licensed window repair professional within 24 hours to address the issue permanently. Avoid DIY repairs unless you have mechanical expertise, as improper adjustments can compromise structural integrity. For safety, ensure the window is locked and closed before attempting any repairs.

Broken window handles pose safety risks, including accidental openings that may lead to falls or unauthorized access. According to the U.S. Consumer Product Safety Commission (CPSC), approximately 2,000 window-related injuries occur annually in the U.S., often involving children stuck in partially open windows. A broken handle exacerbates this risk, as it may allow the window to slide open unexpectedly. Additionally, unresolved issues can weaken the window frame, leading to energy loss and increased heating/cooling costs. The CPSC estimates that 15% of residential window accidents involve faulty hardware, with improper repairs contributing to 30% of preventable incidents. Professional repair services typically cost $150–$300, while DIY attempts without proper tools or knowledge often result in higher long-term expenses due to repeated failures. Data from the National Association of Home Builders also shows that 40% of homeowners delay repairs, risking 20% more energy waste from poorly sealed windows. Proactive maintenance aligns with safety guidelines and reduces liability, as 65% of property insurers require functional hardware to validate claims.
