Andersen Balance System Repair in Wantagh, NY

We recently performed an Andersen balance system repair in Wantagh, NY for a client struggling with window sashes that wouldn’t stay up or slammed shut without warning. This is one of the most common signs of a failed or misaligned balance system, which is responsible for supporting the weight of the sash and allowing smooth vertical movement. At Prestige Window Works, we specialize in Andersen window repairs, and when it comes to balance systems, correct diagnosis and precision repairs are key.

This particular project involved Andersen tilt-in double-hung windows using their proprietary side-load balance system, which includes tension springs, cords, and pivot shoes hidden within the jamb liner. The homeowner in Wantagh had noticed the lower sash wouldn’t hold its position anymore, and the upper sash had begun to stick. Upon disassembly, we found broken cord tensioners and cracked pivot shoes—components that wear out over time due to repeated use and lack of maintenance.

After safely removing the sashes, we inspected the channel balances and confirmed that both the left and right mechanisms had failed. We replaced the damaged components with OEM Andersen balance parts, recalibrated the spring tension to match the sash weight, and ensured both pivot shoes were locked and aligned properly within the track. Andersen balance systems require specific tools and techniques to adjust—especially their tilt-wash series—so we followed manufacturer specs to ensure a long-lasting repair.

The before-and-after difference was immediate. Before, the sash dropped uncontrollably, posing a safety hazard and making everyday use frustrating. After the repair, the windows in this Wantagh home opened with minimal effort and held their position at any height. The new balance system restored not just motion, but consistency. No sticking, no drifting, and no more slamming sashes.

While we were on site, we also checked adjacent units and performed minor weatherstrip replacements and sash realignments, which we regularly handle throughout Wantagh, New Rochelle, and the greater Long Island area. Our services go beyond balance system repairs — we also offer crank mechanism replacements, sash weight adjustments, frame inspections, and glass pane swaps for Andersen and other major window brands.

If your Andersen windows are sagging, sticking, or won’t stay open, it’s likely your balance system needs attention.
