Window Balance Repair for Windows That Won’t Stay Open
A window that slides down after opening, feels unusually heavy, binds during operation, or will not remain in position may have a problem with its balance system or related sash hardware.
Priority Window Glass Repair LLC provides window balance repair and replacement for homeowners, landlords, property managers, and rental properties throughout Virginia, Maryland, and Washington, DC.
Window balances help counteract the weight of a movable sash. When a balance, spring, shoe, cord, pivot component, or related hardware fails, the sash may become difficult to operate or may no longer stay where it is positioned.
Because similar symptoms can also result from alignment, track, sash, pivot-shoe, or other hardware problems, we assess the window before determining which component should be repaired or replaced.
What Is a Window Balance?
A window balance is a counterbalance mechanism used in many single-hung and double-hung windows to offset the weight of the movable sash.
Depending on the window design, the balance system may use springs, pulleys, cords, coils, shoes, pivot components, or other hardware to help the sash move and remain in position.
Different windows use different balance systems. The most common types include spiral balances, channel balances, constant force balances, and block and tackle balances. Here is a breakdown of each:
| Balance System | How It Works | Common Applications | Common Problems |
|---|---|---|---|
| Spiral balance | Spring-loaded spiral rod operates inside a tube | Various older and modern tilt/non-tilt windows | Loss of tension, damaged rod, worn connection |
| Channel / block-and-tackle balance | Spring-and-pulley mechanism housed inside a metal channel | Many vinyl and aluminum single- and double-hung windows | Broken cord, worn spring, damaged fittings or shoe |
| Constant-force / coil balance | Flat coiled spring provides counterbalance force | Many newer tilt and non-tilt window systems | Broken coil, damaged housing, worn pivot shoe |
| Weight-and-cord system | Sash cord or chain connects the sash to concealed counterweights | Many traditional wood windows | Broken cord, pulley problems, disconnected weight |
Balance designs vary between window manufacturers and even between different models from the same manufacturer.
Correct part identification may require the balance type, length, channel dimensions, end fittings or shoes, spring-strength marking, sash weight, pivot configuration, and other window-specific details.
Why Will My Window Not Stay Open?
A worn or failed balance is a common reason a single-hung or double-hung window will not stay open, but it is not the only possible cause.
Possible causes include:
- A weakened or broken balance spring
- A broken cord or pulley component inside a channel balance
- A damaged constant-force coil
- A worn or broken pivot shoe
- A damaged or disconnected pivot bar
- Incorrect balance tension or spring strength
- Sash or frame alignment problems
- Binding, debris, or damaged components within the jamb or track
When a balance can no longer properly counteract the sash weight, the window may drift downward, feel unusually heavy, or close when released.
An inspection helps determine whether the balance itself, a related component, or another part of the window is causing the problem.

What Are the Signs of a Window Balance Problem?
Window balance problems show up in several ways. Here is a symptom guide to help identify the issue:
| What You Notice | Possible Cause | Typical Next Step |
|---|---|---|
| Window slowly slides down | Weak balance, incorrect balance tension, damaged shoe or related hardware | Inspect balance system and sash |
| Window drops when released | Failed or disconnected balance component | Stop normal use and inspect balance system |
| Sash feels unusually heavy | One or both balance mechanisms may not be providing proper support | Inspect balances and related hardware |
| One side of sash sits lower | Balance, shoe, pivot or alignment issue on one side | Inspect both sides and sash alignment |
| Window binds or sticks | Balance, shoe, track, jamb, alignment or sash issue | Determine source of friction before replacing parts |
| Grinding, clicking or scraping | Damaged balance component, shoe, cord, coil or contact point | Inspect moving hardware |
| Tilt sash does not operate correctly | Pivot shoe, pivot bar, tilt latch or balance-related hardware issue | Inspect tilt and pivot components |
These symptoms help narrow the problem, but they do not identify the exact replacement part by themselves. Photos and an on-site inspection can help determine the balance system and related hardware involved.
Can a Window Balance Be Repaired, or Does It Need Replacement?
It depends on the balance system and the component that has failed.
Some balance problems may involve adjustment, re-tensioning, alignment, a pivot shoe, or another replaceable component. When a spring, cord, coil, channel assembly, or other balance component is worn or broken, replacement is often the more appropriate repair.
The correct replacement must be compatible with the existing window and provide the appropriate support for the sash.
If the required balance or compatible hardware is unavailable because of the age or design of the window, we can explain whether another repair approach or a broader window evaluation should be considered.

Can Window Balance Repair Be Done Without Replacing the Whole Window?
When the window frame, sash, glass, and surrounding components remain serviceable, a failed balance or related hardware problem can often be addressed without replacing the complete window.
If the balance is the only failed component, repairing the operating hardware can often avoid a complete window replacement. See our guide to glass-only replacement vs. full window replacement for more information about when existing window components can remain.
Depending on the balance system, the work may involve:
- Removing or positioning the sash as required to access the balance
- Identifying the existing balance system and related fittings
- Checking available markings, dimensions, shoes, pivot components, and sash requirements
- Replacing or adjusting the failed component when appropriate
- Reinstalling the sash
- Checking sash movement and balance through its normal operating range
If the sash also contains cracked glass, see our cracked window glass repair service for glass-replacement options.
For windows with condensation or haze between the panes, insulated glass unit replacement may be needed separately from the balance repair.

Should Both Window Balances Be Replaced at the Same Time?
Sometimes replacing both balances that support the same sash is appropriate, particularly when both components are the same age and one has already failed.
Matched balance systems are designed to support the sash together, and installing components with different wear or spring characteristics can affect operation.
However, the correct approach depends on the balance design, manufacturer requirements, condition of the second balance, and availability of compatible replacement parts.
We inspect the system before determining whether one component or a matched pair should be replaced.
How Window Balance Repair Works
1. Send Photos for Initial Review
Send photos of the complete window, sash, jamb or track area, and any visible balance, shoe, spring, cord, or identifying markings.
2. Initial Problem Review
We review the symptoms and available photos to understand whether the issue may involve the balance, pivot hardware, sash alignment, track, or another operating component.
3. On-Site Balance & Window Assessment
When required, we inspect the sash movement, balance system, attachment points, pivot components, jamb or track condition, and surrounding window assembly.
4. Identify Compatible Repair Parts
The balance type, measurements, strength rating or sash requirements, fittings, shoes, and other relevant details are checked before replacement hardware is selected.
5. Repair or Replace the Failed Components
The appropriate balance or related hardware is adjusted or replaced when compatible parts are available.
6. Reassemble, Test & Clean
The sash is returned to its operating position, movement is checked through its normal range, and the immediate work area is cleaned.
Part availability varies by window manufacturer, age, balance system, and hardware design, so some repairs may require additional part identification or sourcing before completion.
Can a Window That Will Not Stay Open Be a Safety Concern?
A sash that will not remain supported can create a safety concern, particularly if it drops or closes unexpectedly while someone is operating the window.
Possible concerns include:
- Fingers or hands being caught between the sash and sill
- A heavy sash closing unexpectedly
- Difficulty using the window normally for ventilation
- Additional stress on sash, pivot, lock, or balance components when the window is forced
If the sash will not stay in position or feels unusually heavy, avoid normal operation until the cause has been assessed.
What Should You Do If Your Window Will Not Stay Open?
Avoid forcing a window with a broken balance. Applying extra pressure on a window with a failed spring can damage the sash, crack the glass, or cause the sash to fall suddenly.
Instead, take these steps:
- Avoid continuing to raise and release a sash that will not stay supported.
- If the window can be closed safely without forcing it, leave it closed until the problem is assessed.
- Keep children and pets away from a sash that may drop unexpectedly.
- Do not force, re-tension, detach, or reconnect spring-loaded balance components unless you are trained to work with that system.
- If safe, take photos of the complete window, sash corners, jamb or track, and any visible balance or hardware.
- Note the window manufacturer or any balance markings if they are clearly visible without disassembling the window.
- Request a window-balance assessment and compatible-part identification.
Window balances and springs can store mechanical tension, and incorrect handling can damage the sash or hardware. The balance system should be identified before adjustment or replacement is attempted.

A window balance is a counterbalance mechanism used in many single-hung and double-hung windows to offset sash weight so the movable sash can open, close, and remain in position.
A worn or failed balance is a common cause, but other possibilities include damaged pivot shoes, disconnected hardware, alignment problems, track or jamb issues, or another sash component. An inspection helps identify the cause.
The window may no longer have enough counterbalance force to support the sash. A weak or failed balance, damaged shoe, disconnected component, or incorrect tension can cause the sash to drift downward.
Often, yes. When the frame, sash, glass, and surrounding components remain serviceable, the balance or related hardware can often be repaired or replaced without replacing the complete window.
Common signs include a sash that slides down, drops when released, feels unusually heavy, sits unevenly, binds, or makes unusual scraping, clicking, or grinding sounds during operation.
Yes. A sash that drops unexpectedly can catch fingers or hands and may be difficult to operate safely. Avoid normal use if the sash will not remain supported.
Sometimes. Balance or pivot-hardware problems can contribute to a stuck or difficult window, but track contamination, alignment, sash, jamb, paint, or other hardware conditions can produce similar symptoms. The cause should be identified first.
Sometimes. Paired balances support the same sash together, so replacing both may be appropriate when they are the same age or have uneven performance. The correct approach depends on the specific balance system and component condition.
Yes. We coordinate window balance repair with landlords and property managers, including tenant-occupied properties and scheduling with authorized contacts.
Yes. Photos of the complete window, sash, jamb, track, and visible hardware can help with an initial review. Exact balance identification may still require measurements, markings, sash weight, or inspection of the existing hardware.
Cost depends on the window design, balance system, number of affected components, part availability, sash condition, and whether related hardware such as pivot shoes or bars also requires repair. Send photos for an initial review and free estimate.
