Step-by-step fix
Step 1: Confirm the balance shoe or pivot hardware is the problem
- Open and close the window slowly and watch for one side dropping, the sash twisting, the sash refusing to tilt back in, or the bottom corner pulling away from the track.
- Tilt the sash in if your window design allows it and inspect the lower side hardware for cracks, bent metal, missing tabs, or a pivot bar that no longer stays engaged in the shoe.
- Compare both sides. If one side is damaged or sitting lower than the other, that usually points to failed balance shoe or pivot hardware rather than a simple cleaning issue.
- Check that the sash frame itself is not split and that the side tracks are not badly bent or packed with debris.
If it works: You have a clear hardware failure or a worn part that no longer holds the sash correctly.
If it doesn’t: If the window is just sticky but the hardware looks intact, clean the tracks and check for paint buildup or dirt before replacing parts.
Stop if:- The sash frame is cracked, the glass is loose, or the side jamb is bent enough that new hardware will not sit correctly.
- You cannot identify how the sash releases without forcing it.
Step 2: Remove the sash and make the area safe to work
- Clear the floor and window stool so you have room to support the sash with both hands.
- Unlock the window and raise it a few inches unless your window style requires a different release position.
- Release the sash according to its normal tilt or removal method, then support both sides evenly as you lift the pivot bars out of the balance shoes.
- Set the sash on a padded surface so the corners and glass are protected.
- If the balance system has take-out clips or a spring-loaded channel, keep your hands clear of any part under tension and do not let loose hardware snap upward.
If it works: The sash is out and you can reach the damaged hardware without fighting the weight of the window.
If it doesn’t: If the sash will not release, look for hidden tilt latches, take-out clips, or retaining screws before applying more force.
Stop if:- A spring-loaded balance is loose, whipping, or cannot be controlled safely.
- The sash is too heavy or awkward to remove safely without a second person.
Step 3: Match the old part before installing the replacement
- Remove the damaged balance shoe or pivot hardware carefully and keep the old part beside the new one.
- Compare the shape, width, height, slot opening, screw locations, and how the pivot bar fits into the part.
- If you are replacing a balance-related piece, note any stamp, length marking, or handed shape from the old assembly.
- Clean dirt and broken plastic from the side track so the new part can slide and seat fully.
If it works: The replacement matches the old part closely enough to install without modifying the window.
If it doesn’t: If the new part does not match the old one, pause and reorder the correct hardware using the old part dimensions and markings.
Stop if:- The track is cracked, badly worn, or missing sections that are supposed to hold the hardware in place.
Step 4: Install the new balance shoe or pivot hardware
- Slide or fasten the new part into the same position and orientation as the original.
- If the part connects to a balance, attach it the same way the old one was attached and make sure it sits square in the track.
- If you removed a pivot bar or corner hardware from the sash, reinstall it firmly so it is straight and fully seated.
- Move the new shoe by hand if possible to confirm it travels smoothly and does not bind in the jamb.
- Tighten screws snugly without overtightening into vinyl or soft sash material.
If it works: The new hardware is secure, aligned, and able to accept the sash pivot point cleanly.
If it doesn’t: If the part binds or sits crooked, remove it and check for debris, reversed orientation, or a mismatch in size.
Stop if:- The new part will not seat because the jamb liner or sash corner is damaged.
- Screws will not hold because the mounting area is stripped or broken.
Step 5: Reinstall the sash and reconnect both sides evenly
- Lift the sash back to the opening and line up each pivot bar with its matching balance shoe or pivot receiver.
- Insert one side, then the other, while keeping the sash level so you do not twist the frame.
- Tilt or rotate the sash back into the tracks and lower it gently to confirm both sides stay engaged.
- Lock and unlock the window once to make sure the sash is sitting fully back in its normal position.
If it works: The sash is back in place, sits level, and stays engaged on both sides.
If it doesn’t: If one side keeps popping out, remove the sash again and recheck pivot bar alignment and whether both shoes are set at the same height.
Stop if:- The sash cannot be reinstalled without forcing the corners or bending the track.
Step 6: Test the repair in real use
- Open the window several times through its normal travel and watch that both sides rise and lower together.
- If it is a tilt window, tilt it in and return it to the frame to confirm the pivot hardware stays engaged.
- Leave the sash partly open for a minute if the window is designed to stay up on its own, then check whether it holds position.
- Close and lock the window and confirm the meeting rails line up and the sash seals evenly.
If it works: The window moves smoothly, stays aligned, and closes and locks normally after repeated use.
If it doesn’t: If the sash still drops, twists, or will not lock, the balance itself or another sash component may also need repair.
Stop if:- The window still feels unstable after the hardware replacement or the sash will not stay captured in the track.

FAQ
How do I know whether I need the balance shoe or the pivot hardware?
If the pivot bar at the sash corner is bent, loose, or broken, replace that hardware. If the pivot bar is fine but will not stay captured in the side track, the balance shoe is often the failed part. Many homeowners inspect both together because wear on one can damage the other.
Can I replace just one side?
Yes, if only one part is clearly damaged and the other side is still tight and working smoothly. If both sides show wear or the window has been operating unevenly for a while, replacing both matching parts can help the sash track more evenly.
What if the window still will not stay up after I replace the hardware?
That usually points to a worn balance assembly, not just the shoe or pivot connection. Recheck that the new part matches the old one, then inspect the balance for weak spring tension, damage, or disconnection.
Do I need to remove the whole window frame?
No. This repair is usually done with the sash removed from the frame while the main window frame stays in place.
Can I use the old screws with the new part?
Usually yes if they are straight, not rusted, and still hold tightly. If the old screws are stripped or the new part came with matching hardware, use the better-fitting option.
