How to Fix A Window That Won’t Stay Up: Complete 5-Step Guide

Windows that won’t stay up when you open them aren’t just an irritation—they can be potentially dangerous. A falling window could cause injury to a child or pet if it drops on them when they’re looking out of the opening. This kind of home repair shouldn’t be ignored.

In this complete guide, we’ll walk you through exactly how to fix a window that won’t stay up, explain why this problem happens, show you when repair makes sense versus replacement, and provide troubleshooting steps to diagnose the issue.

Why Won’t My Window Stay Up? Common Causes

One of the main reasons a window doesn’t stay up is likely that one or both of the balances of the window have become detached from the sash. This is the most common reason for a falling window.

The Three Main Culprits:

Broken or Detached Balances (Most Common – 60% of cases)
- Balances are spring-loaded mechanisms that counterweight the window
- They wear out over time, typically after 15-20 years
- One or both balances may have detached from the window sash
Damaged Pivot Bar (Common – 25% of cases)
- The pivot bar connects balances to the window sash
- Can snap, bend, or become detached
- Easy to spot and relatively simple to replace
Worn or Broken Shoes (Less Common – 15% of cases)
- Shoes are small plastic or metal blocks inside the frame
- They provide grip for the pivot bar
- Damaged shoes mean nothing for the bar to hold onto

Other Contributing Factors:

Paint buildup on window tracks (wood windows)
Damaged or bent window tracks
Incorrect window installation
Age of window (issues increase significantly after 15-20 years)

How to Fix a Window That Won’t Stay Up: 5-Step Process

Step 1: Diagnose the Problem

Before you start repairs, identify what’s actually broken:

Visual Inspection Checklist:

Open the window fully
Look for the pivot bar on each side of the window
Check if the pivot bar is snapped, bent, or detached
Inspect the shoes (plastic/metal blocks in frame)
Try to determine if balances are functioning

Quick Test:

Lift the window halfway
Release it slowly
Does it fall immediately? → Balance/shoe problem
Does it drop slowly? → Weak balances (may just need adjustment)
Does one side drop? → Single balance failure

What You’ll Likely Find:

Snapped or bent pivot bar (visible damage)
Detached balance (hanging loose in frame)
Damaged shoes (cracked or broken plastic pieces)

Step 2: Gather Tools & Materials

Tools Needed:

Phillips head screwdriver
Flathead screwdriver
Utility knife (to cut paint seal if needed)
Flashlight
Needle-nose pliers (optional, helpful)
Work gloves

Materials to Buy: (Cost estimates are 2025 averages)

Replacement pivot bars: $5-$15 per pair
Replacement shoes: $3-$8 per pair
Replacement balances: $20-$40 per pair (depends on window size)
Replacement balance springs: $15-$30 per pair

Where to Buy Parts:

Local hardware stores (Lowe’s, Home Depot, Ace)
Online: Amazon, Repair Clinic, Window Parts Depot
Window manufacturer (if you know your brand)
Thompson Creek service department (for our windows)

Pro Tip: Take a photo of your window components and bring it to the hardware store. Better yet, if possible, remove the broken part and bring it in for exact matching.

Total DIY Cost: $20-$100 depending on what needs replacement

Step 3: Remove the Window Sash

Safety First: Have someone help you. Windows are heavy and awkward to handle.

Removal Process:

For Vinyl Windows (Most Common):

Open the window fully
- Pull window down as far as it goes
Locate the tilt latches
- Look at the top of the sash (usually near corners)
- Small plastic tabs or buttons
Engage tilt latches
- Push both latches inward simultaneously
- Tilt the window toward you
Lift and remove
- Once tilted, lift the window up and out
- The bottom will clear the frame
- Have your helper support the weight

For Older Wood Windows:

Score paint seal
- Use utility knife to cut paint seal around sash
- Be careful not to damage wood
Remove interior stops
- Carefully pry off vertical trim pieces
- Keep these – you’ll need to reinstall them
Lift out sash
- Window should now lift out
- Watch for balance cords on very old windows

For Aluminum Windows:

Check for release clips
- Usually located on window sides
Press clips and lift
- Mechanism similar to vinyl windows

Step 4: Replace the Faulty Components

Now that the sash is out, you can access all components.

If Replacing Pivot Bar:

The pivot bar is the easiest fix – this bar connects the balances to the sash and holds it securely in place. A snapped or bent pivot bar is obvious, and this part is easy to replace.

Remove old pivot bar
- Locate the small screw or clip holding it
- Unscrew or unclip the pivot bar
- Note the orientation before removing
Install new pivot bar
- Position new bar exactly like the old one
- Secure with screw or clip
- Make sure it’s firmly attached
- Repeat on other side if needed
Test engagement
- Check that pivot bar slides into the shoe
- Should have slight resistance but move smoothly

Time: 15-30 minutes Cost: $5-$15

If Replacing Shoes:

Shoes are small plastic or metal blocks that sit inside the frame. If these are damaged, there’s nothing for the bar to grip to hold the window in position.

Locate the shoes
- They’re in the window track/channel
- Usually one on each side
Remove old shoes
- May be held by small screws
- Or may slide/snap out
Install new shoes
- Ensure correct orientation (check instructions)
- Secure with screws or snap into place
- Verify they’re level and secure
Test grip
- Insert pivot bar into shoe
- Should lock firmly with slight click

Time: 20-40 minutes Cost: $3-$8

If Replacing Balances:

Most balances are held in place with one or two screws.

Remove old balances
- Unscrew balance from frame (usually 1-2 screws)
- Carefully detach from pivot bar or shoe
- Note: Balance may have spring tension – hold firmly
Install new balances
- Position new balance in same location
- Screw into frame firmly
- Connect to pivot bar/shoe mechanism
Adjust tension (if adjustable)
- Some balances have tension adjusters
- Start with medium tension
- Can adjust after testing
Replace both sides
- Always replace both balances, even if only one failed
- Ensures even operation and extends overall life

Time: 45 minutes to 1.5 hours Cost: $20-$40 per window

Step 5: Reassemble and Test

Reinstallation Process:

Reinsert the window sash
- Reverse the removal process
- Tilt window into frame
- Seat it properly in tracks
Engage mechanisms
- Make sure pivot bars slide into shoes
- Listen for engagement clicks
- Push window to upright position
Test operation
- Open window fully
- Release slowly – it should stay up
- Try different positions (¼, ½, ¾ open)
- Check both sides operate evenly
Test multiple times
- Open and close 10-15 times
- Verify smooth operation
- Listen for unusual sounds

For wood windows:

Reinstall interior stops
Use finish nails (not the same holes if possible)
Touch up paint as needed

Signs Your Repair Worked: ✓ Window stays at any open position ✓ No unusual sounds when operating ✓ Both sides operate evenly ✓ Window locks properly when closed

What if It Still Doesn’t Work?

Recheck pivot bar/shoe engagement
Verify balances are properly installed
Check for additional damage (warped frame, damaged sash)
May indicate need for full window replacement

When to Repair vs. Replace Your Window

Not every window that won’t stay up needs replacement, but age and overall condition matter.

FAQs: Window Repair Questions

Why won’t my window stay up?

The most common reason is failed or detached window balances—the spring-loaded mechanisms that counterweight your window. Over time (typically 15-20 years), these balances wear out, break, or detach from the window sash. Other causes include broken pivot bars (the connecting piece between balances and sash) or damaged shoes (the grip points in the frame). About 60% of cases are balance-related, 25% are pivot bar issues, and 15% are shoe problems.

How much does it cost to fix a window that won’t stay open?

DIY repair costs $20-$100 in parts (pivot bars, shoes, or balances), plus 1-2 hours of your time. Professional repair typically costs $150-$300 per window, including labor and parts. Exact cost depends on what’s broken: pivot bars ($5-$15), shoes ($3-$8), or complete balances ($20-$40 per pair). If multiple windows need repair or the window is very old, replacement may be more cost-effective ($300-$700 per window installed).

Can I fix a window myself or do I need a professional?

Most homeowners can fix a window that won’t stay up if the problem is a broken pivot bar or worn shoes—these are straightforward replacements requiring only a screwdriver. Balance replacement is moderately challenging but still DIY-friendly if you’re comfortable with basic home repairs. Call a professional if: (1) you’re uncomfortable removing the window sash, (2) the window frame shows damage or rot, (3) you can’t identify the problem, or (4) the window is very large or difficult to access.

What tools do I need to fix a window that won’t stay up?

You’ll need: Phillips head screwdriver, flathead screwdriver, utility knife (for paint seals), flashlight, and work gloves. Optional but helpful: needle-nose pliers. Parts needed depend on what’s broken: replacement pivot bars ($5-$15), shoes ($3-$8), or balances ($20-$40). Total tool investment is minimal—most homeowners already have these basic tools.

How long does it take to repair a window?

DIY repair time varies by component: pivot bar replacement takes 15-30 minutes, shoe replacement takes 20-40 minutes, and full balance replacement takes 45 minutes to 1.5 hours. Add 30-45 minutes if you’ve never removed a window sash before. Professional repairs typically take 30 minutes to 1 hour per window. First-time DIYers should budget 2-3 hours to be safe.

Are window balances universal or window-specific?

Window balances are NOT universal—they’re specific to window size, weight, and manufacturer. You’ll need to match: (1) balance type (spiral, block-and-tackle, or constant force), (2) length, (3) load rating (based on window weight), and (4) mounting style. Take photos of your existing balances and window label, or bring the old balance to the hardware store for exact matching. Using wrong balances will result in a window that still won’t stay up.

Should I repair or replace my old windows?

Repair if: window is less than 15 years old, only one component is broken, window is otherwise energy-efficient, and no other problems exist. Replace if: window is 20+ years old, you have multiple issues (drafty, foggy, leaky), window is single-pane, or frame shows rot/damage. Consider that new energy-efficient windows save $80-$150 per window annually in energy costs, often paying for themselves within 6-8 years while improving comfort and home value.

What causes window balances to fail?

Window balances fail due to: (1) Age—most last 15-20 years before weakening, (2) Frequent use—daily operation accelerates wear, (3) Weight stress—oversized or heavy windows strain balances, (4) Environmental factors—humidity, temperature extremes, and UV exposure degrade materials, (5) Poor installation—incorrect balance type or rating causes premature failure. Once one balance fails, the other typically fails soon after due to increased load.

How often do window parts need replacing?

In well-maintained windows: balances last 15-20 years, pivot bars last 20-25 years, shoes last 20-30 years. However, once a window reaches 15-20 years old, multiple components may start failing within 1-2 years of each other. This is why serial repairs on old windows often make less financial sense than replacement—you’re essentially rebuilding an outdated, inefficient window piece by piece.

Can vinyl windows be repaired?

Yes, vinyl windows can be repaired for common issues like failed balances, broken pivot bars, or damaged shoes. Unlike wood windows, vinyl doesn’t rot, so frame repairs are rarely needed. However, if the vinyl sash itself is cracked or the frame is warped, replacement is the only option—vinyl cannot be repaired once structurally damaged. Most vinyl window issues are related to internal mechanisms (balances, hardware) which are readily repairable.
