When Is It Time to Replace Your Windows?

11/26/20252 min read

Windows play a major role in home comfort, energy efficiency, and curb appeal — especially in the Pacific Northwest, where we deal with long rainy seasons, cold winters, and moisture-heavy conditions.
Knowing when your windows need replacement can save you money, prevent damage, and improve your home’s value.

Here are the top signs it’s time to replace your windows.

1. Drafts and Cold Air Leaks

If you feel cold air coming in around your windows — especially in winter — it’s a clear sign the seals have failed.

Signs include:

  • Rooms feel colder than others

  • Air drafts around the frame

  • Higher heating bills

Seattle’s damp climate wears out seals faster than other regions.

2. Foggy Windows or Condensation Between the Glass

This means the insulated glass seal is broken, and the window is no longer energy-efficient.

Look for:

  • Moisture trapped between panes

  • Fog that never wipes away

  • Cloudy or milky glass

This is one of the most common reasons we replace windows on the Eastside.

3. Difficulty Opening or Closing

Windows should operate smoothly. If they stick, jam, or feel heavy, the frame or hardware is failing.

Common causes:

  • Warped frames from moisture

  • Old aluminum or wood windows

  • Rusted or broken hardware

This is especially common in older Bellevue and Seattle homes.

4. Cold Glass and Poor Insulation

If the interior glass feels very cold in winter, it means the window isn’t insulating properly.

This can lead to:

  • Heat loss

  • Higher energy bills

  • Indoor comfort issues

Modern vinyl windows offer far better insulation.

5. Visible Damage or Rot

Seattle’s rain can cause damaged or rotted frames — especially in older wood-frame windows.

Signs of damage:

  • Soft or spongy wood

  • Water stains

  • Peeling paint

  • Mold or mildew

  • Cracked frames

Once the frame is compromised, replacement is the only solution.

6. Outside Noise Is Getting Louder

If you hear traffic, neighbors, or airplanes more clearly than before, your windows are not sealing properly.

Modern dual-pane windows drastically reduce noise.

7. Rising Energy Bills

Old or damaged windows make your heater and AC work harder.

If your utility bills keep rising, poor window insulation may be the cause.

8. Fading Floors, Furniture, or Curtains

Old single-pane windows let in too much UV light, causing fading.

New windows protect your home from:

  • UV damage

  • Heat exposure

  • Sun bleaching

9. Windows Are Over 20–25 Years Old

Most older windows weren’t designed for today’s energy standards.

Typical replacement lifespan:

  • Vinyl: 20–30 years

  • Wood: 15–25 years

  • Aluminum: 15–20 years

If your windows are original to a 1990s or early 2000s home, replacement is often needed.

10. Preparing to Sell Your Home

New windows boost curb appeal and are a major selling point for Eastside buyers.

Benefits include:

  • Higher home value

  • Better energy efficiency rating

  • Stronger first impression

  • Updated modern look
