How to Replace Internal Tilt Latches in Your Windows: A Step-by-Step Guide

Internal tilt latches are a commonly found component in windows, particularly double-hung windows. They enable the window sash to be tilted inwards easily for cleaning or ventilation purposes. However, prolonged use or damage can lead to problems with the latches, making it challenging to operate the window. In such instances, it may be necessary to replace the internal tilt latches to restore optimal functionality. Here is a professional guide on how to replace internal tilt latches in your windows.

Identification & Installation Instructions

Step 1: Identify the Type of Tilt Latch 

Before commencing the replacement process, you must first identify the type of latch installed in your window. The two primary types of internal tilt latches are spring-loaded and slide-on. Spring-loaded latches feature a small metal spring that keeps the latch in position. To release the latch, you need to press down on a small tab located on the latch. Conversely, slide-on latches slide onto a metal channel on the window sash and are commonly found in older windows.

Step 2: Remove the Old Tilt Latch

After identifying the type of tilt latch, you can proceed to remove the old latch. Begin by opening the window and locating the tilt latches on the inside of the window sash. For spring-loaded latches, use a screwdriver to press down on the tab located on the latch to release it from the window sash. If your window features slide-on latches, remove the screws holding the latch in place and slide it off the metal channel.

Step 3: Measure the Tilt Latch 

Before purchasing a replacement tilt latch, you must measure the old latch's dimensions to ensure you acquire the right size. Measure the width, height, and distance between the screw holes to determine the appropriate replacement latch size for your window.

Step 4: Install the New Tilt Latch 

After purchasing a replacement tilt latch, proceed to install it. Insert the latch into the hole on the window sash and press down on the tab to secure it in place for spring-loaded latches. For slide-on latches, attach the latch to the metal channel with screws.

Step 5: Test the Window 

Finally, test the window to ensure that the new tilt latch is functioning properly. Open and close the window multiple times, verifying that the tilt latch securely holds the window sash in position.
