Installation Guide: Window Balance Replacement & Repair
Preserving Historic Wood Windows with Modern Solutions
Today’s homeowners value the quality craftsmanship of original wood sash windows. Rather than replacing these beautiful architectural elements with aluminum or vinyl alternatives, many are choosing restoration. In fact, numerous historic districts now require maintaining or authentically replacing original windows to preserve neighborhood character.
Why Preserve Wood Windows?
Wood provides superior insulation compared to modern materials, though traditional single-pane glass remains a weak point for energy efficiency. Fortunately, you can improve performance by:
- Retrofitting existing frames with new sashes
- Installing double-pane glass
- Adding UV-protective window films
Important safety note: When upgrading window glass, always adjust the balance mechanism to properly support the increased weight. Undersized balances can lead to unexpected sash drops, potentially causing injury.
The Timeless Benefits of Double-Hung Windows
Double-hung windows experienced popularity for centuries (through the 1960s) thanks to their natural ventilation design. Opening both top and bottom sashes creates convection airflow—cooler air enters through the bottom while warmer air escapes from the top. This practical feature remains relevant today:
- Reduces energy costs in regions with cool evening temperatures
- Provides effective ventilation without mechanical systems
- Complements classic architectural styles
