When Your Double-Hung Windows Fail, Smart Repair Saves Thousands Over Premature Replacement

Most homeowners facing stuck, drafty, or falling double-hung windows assume they need expensive full window replacements. However, understanding your window’s balance system—the hidden mechanism that makes opening and closing effortless—can save you significant money. The most common cause of these problems is a broken window balance also called window spring or spring balance. If your window frame is in good condition, replacing the spring balance is the best and most affordable option to go for.

Understanding Double-Hung Window Balance Systems

Window balances are only found in windows that move up and down, referred to as either single or double-hung windows. The balance mechanism helps you open your windows vertically countering the force of gravity. These systems have evolved significantly over the decades, with four main types commonly found in residential properties.

The cord and weight balance system was the first type of balance system installed in sash windows. Windows with cord and weight balance systems have a box built into each side of the window (the jambs) where cast iron or lead weights are suspended. The weights are attached to a cotton cord that extends up the jamb, over a pulley, and onto the operable sash. While historically significant, these systems are costly to repair and increasingly difficult to service.

Modern homes typically feature spiral balances or constant force systems. Spiral window balances are composed of a spiral rod and spring within a metal or plastic tube, they’re sometimes called a tube balance. Each side of the window sash is connected to the rod of the balance at the bottom corner. The most advanced option, constant force balance systems seem to be the most durable balances we’ve seen thus far. This balance uses a stainless steel coil system that is encased and operates like a tape measure. Because of its design, the constant force balance system is unlikely to run into the same problems that systems with springs and cords run into.

Identifying When Repair Makes Financial Sense

Fixing a window spring or sash balance costs $50 to $100. Springs allow the sash to open and stay in place when opened. Springs get damaged, misaligned, or out of balance with repeated use and usually require a simple readjustment. Compare this to full window replacement costs, which range from $400 to $2,000 per window installed if the window is beyond repair. Replacing a triple-pane window costs $450 to $3,000 per window.

The key factors determining repair viability include frame condition, balance type, and part availability. If your window frame is in good condition, replacing the spring balance is the best and most affordable option to go for. We would also highly recommend replacing both balances on each end of the window so that they will be in great working condition.

The cost of replacing a vinyl window balance system varies depending on the type of balance system and the brand. Replacement parts can range from $10 to $50 per window. On average, a balance system can last between 10 to 20 years. Professional installation typically adds modest labor costs, making total repair expenses significantly less than replacement.

Professional Assessment: The Critical First Step

Proper diagnosis requires expertise to identify the specific balance type and determine whether repair or replacement offers better value. If you can identify and source the original parts of your window balance, you can, potentially, replace it. To do so would require identifying the window manufacturer and series, the part # of the balance system, and secure a skilled technician to perform the replacement.

When Replacement Becomes Necessary

Certain conditions make replacement more cost-effective than repair. The only reason you would want to repair a cord and weight balance is if you can’t replace the window. These systems cost more to repair because you have to remove the sash completely. On top of that, you may have a hard time finding a window repairman who knows how to work with these systems.

Frame deterioration, extensive structural damage, or obsolete balance systems with unavailable parts typically warrant full window replacement. Expect much higher costs if your window has sustained excessive damage, such as a rotten frame or damaged windowsill. If the damage is too extensive, you may need to budget for window replacement costs, which can be more cost-effective than ongoing repairs.
