Old Windows Letting Heat In? Signs It’s Time to Replace
Key Takeaways:
- If one room stays hot, the glass feels warm, or the windows draft, rattle, stick, or let in more noise, the issue is usually an aging builder-grade unit that has reached the end of its useful life.
- The smartest first step is to target the worst rooms, usually west- and south-facing bedrooms and living spaces, then decide whether a phased replacement or whole-home plan makes the most sense for your budget.
- In Southern Nevada, better comfort comes from matching the window to the house: heat-blocking glass matters, fiberglass frames outperform aluminum in extreme temperatures, and a good consultation shows exactly where to start.
