Replacing uPVC window hinges is a task that many homeowners face at some point.

This guide will walk you through the process, from understanding uPVC window hinges to maintaining them after replacement.
Understanding uPVC Window Hinges
What are uPVC window hinges?
uPVC window hinges, also known as friction stays, are the hardware that allows your window to open and close smoothly. They connect the window sash (the movable part) to the frame and provide support and control during operation.
Types of uPVC window hinges
There are several types of uPVC window hinges, including:
- Standard friction stays
- Restricted friction stays (for child safety)
- Easy-clean egress hinges (for fire escape windows)
- Storm-proof hinges (for added security and weather resistance)
Signs that your uPVC window hinges need replacement
Look out for these indicators:
- Difficulty in opening or closing the window
- Squeaking or grinding noises during operation
- Visible rust or corrosion
- The window not staying open at desired positions
- Drafts or water leaks around the window edges
Preparing for Replacement
Tools and materials needed
Gather the following before starting:
- Replacement hinges (matching your window type and size)
- Screwdriver (typically Phillips head)
- Drill (optional, for new screw holes)
- Measuring tape
- Lubricant spray
- Clean cloth
Safety precautions
- Wear safety glasses and gloves
- Ensure proper support for the window sash when removed
- Work with a partner, especially for large or high windows
Measuring and identifying the correct replacement hinges
Measure the length and width of your existing hinges. Note the stack height (typically 13mm or 17mm) and the track width (usually 13mm, 17mm, or 22mm). Ensure you order the correct type for your window orientation (top-hung or side-hung).
Step-by-Step Replacement Process
Removing the old hinges
- Open the window fully to access all screws
- Support the window sash to prevent it from falling
- Remove the screws connecting the hinge to the frame and sash
- Carefully detach the window sash from the frame
Cleaning and preparing the window frame
- Clean the areas where the old hinges were attached
- Check for any damage to the frame or sash and repair if necessary
- Ensure all surfaces are dry before proceeding
Installing the new hinges
- Position the new hinge on the frame, aligning it with existing screw holes
- If needed, mark and drill new holes for a secure fit
- Attach the hinge to the frame with screws, but don’t fully tighten yet
Reattaching the window sash
- Carefully lift the sash back into position
- Align the sash with the hinge on the frame
- Secure the hinge to the sash with screws
- Fully tighten all screws on both the frame and sash sides
Testing and adjusting the new hinges
- Slowly open and close the window to check for smooth operation
- Adjust the hinge tension if necessary (refer to manufacturer instructions)
- Ensure the window closes tightly and evenly against the frame
Troubleshooting Common Issues
Misalignment problems
If the window doesn’t close evenly, slightly loosen the screws and adjust the position of the hinges. Retighten once aligned correctly.
Difficulty in opening or closing
Check for over-tightened screws or debris in the hinge mechanism. Clean and lubricate as needed.
Gaps around the window frame
Ensure the hinges are the correct size and type for your window. Adjust the hinge position or consider adding weatherstripping for a tighter seal.
Maintenance Tips for uPVC Window Hinges
Regular cleaning and lubrication
Clean hinges every 6-12 months with a damp cloth and apply a silicone-based lubricant to moving parts.
Adjusting hinge tension
Most hinges have adjustment screws to increase or decrease tension. Refer to your hinge’s manual for specific instructions.
