When to Consider Window Replacement
Not sure if it’s time to upgrade your windows? Watch for these common signs that indicate it may be time for a replacement.
- Drafts & Temperature Changes – If you feel cold air coming in, your windows may have sealing issues.
- Higher Energy Costs – Poor insulation forces your HVAC system to work harder, increasing expenses.
- Difficult Window Operation – Struggling to open or close windows may indicate warping or damage.
- Condensation Between Panes – A broken seal reduces energy efficiency and should be addressed.
- Visible Wear and Tear – Cracked glass, rotting frames, or fading finishes signal it’s time for an upgrade.
- Increased Noise Levels – Older windows allow more outside noise, affecting indoor tranquility.
