Common home windows issues in California


California’s climate varies a lot among the state’s different regions. Weather affect windows differently in the north and in mountains compared to the south and its dryer areas.

  • Seal failure: Temperature swings in the north can cause seals on double-pane windows to break, allowing moisture in and fogging the window. These typically need replacing.
  • Warped frames: Heat and cool cycles can warp window frames, making them stick or impossible to open. Minor warping might be fixable, but severe cases require replacements.
  • Weatherstripping damage: Dry summers can crack window seals, letting in drafts. But weatherstripping is usually a cheap fix. However, if the window frame itself is damaged, a replacement might be needed.
  • Broken panes: Extreme event, like an earthquake, fires, debris or strong winds can break a window panes. Small cracks might be repairable, but larger ones require replacements.
  • Outdated windows: Older, inefficient windows on older homes can lead to high energy bills. Replacing them with energy-efficient options can save you money in the long run.

If you didn’t make your mind to replace a window yet, you can first see if the window(s) can be repaired since it’s often cheaper. If you are a little handy, can DIY: there are many good videos from This Old House.


If you’re already decided to purchase new windows, you first need to decide which model to choose and who will install your windows.
