Double Hung Windows Balance System Replacement

Working on double hung windows might seem like a straightforward task, but when the balance system begins to fail, that’s when the real intricacies appear. We recently tackled a double hung window balance system replacement in Selden that was a perfect example of why this repair demands attention to detail. The sash had become difficult to operate, tilting unevenly and refusing to stay open — all classic signs that the balance system had reached its limit. At Prestige Window Works, we specialize in double hung window repairs like this, and this project was a great reminder of how a properly functioning balance system plays a key role in window performance.

Double hung windows are built with vertical sashes that operate independently, usually relying on a coil, block-and-tackle, or spiral balance system hidden inside the jambs. Over time, friction, corrosion, or internal failure can throw these balances off, making window operation unreliable or even dangerous. In this case, the original balance was a spiral type, rusted out and broken at the connection point. Before we could even access the broken hardware, we had to carefully remove the sashes and interior stops without damaging the window casing — a process that requires experience and patience.

Once we removed the damaged balances, we assessed the frame to ensure it hadn’t been warped or damaged from long-term strain. Thankfully, it was solid — typical of well-made double hung windows. We selected high-quality spiral balance replacements that matched the window weight and sash height exactly. Improper calibration here leads to windows that either slam shut or don’t stay up. Our team at Prestige Window Works installed new pivot shoes, re-aligned the sash, and tensioned the new balances to make sure both sashes operated smoothly and evenly.

After installation, we tested everything rigorously. The difference was instantly noticeable — the sashes lifted with almost no effort and held their position at any height. Looking at the before image, the window was visibly misaligned, and the sash was stuck at a tilted angle. Now, it sits flush, opens with one hand, and locks without issue. These are the kinds of results homeowners in Selden deserve when dealing with double hung window balance system issues.
