Double-pane windows are designed to provide better insulation and energy efficiency, but over time, they can show signs of wear that may indicate it's time for a replacement. Look for issues like condensation between the panes, which can signal a broken seal, or noticeable drafts that compromise your home's comfort. Additionally, consider the age of your windows and any visible damage to the frames. Replacing windows can be a significant investment, so it's essential to weigh the benefits of improved energy efficiency against the costs.
