Windows don’t fail all at once. They fail slowly, one degree of draft and one percentage point of your energy bill at a time, which is why so many Seattle and Tacoma homeowners live with underperforming windows for years without realizing it. Here are the signs worth paying attention to, and what typically happens once you decide to replace them.
1. You Can Feel a Draft Near the Window, Even When It’s Closed
Hold your hand near the edge of the frame on a windy day. If you feel air movement with the window fully latched, the seals or weatherstripping have likely broken down. In older aluminum or single-pane windows, this is extremely common by the time the window is 20-30 years old.
2. Condensation or Fog Between the Glass Panes
Modern double-pane windows have a sealed gas layer between two panes of glass. When that seal fails, moisture gets trapped between the panes and shows up as permanent fog or condensation that won’t wipe away, since it’s on the inside of the sealed unit. This is a clear sign the insulating value of the window is gone, even if the rest of the frame looks fine.
3. Your Energy Bills Keep Climbing
Windows are one of the biggest sources of heat loss in older homes. If your heating costs have crept up year over year without a clear reason, and your windows are original to a home built before the 1990s, they’re a reasonable place to start looking. Newer windows with low-E coatings and proper gas fill are built specifically to reduce that kind of heat transfer.
4. Windows Are Hard to Open, Close, or Lock
Wood swells and frames settle over time, especially in our wet climate. If you’re wrestling with a window every time you want fresh air, or a lock won’t fully engage, that’s both a comfort issue and a security one worth addressing.
5. Visible Wood Rot or Damage Around the Frame
Soft, discolored, or crumbling wood at the sill or frame is a sign moisture has been getting in, often for a while. Once rot sets into a window frame, patching it is usually a short-term fix at best. In these cases, replacement also gives you a chance to check for and repair any hidden damage to the surrounding wall framing.
Window Replacement FAQ
How long do vinyl replacement windows last?
Quality vinyl replacement windows typically last 20-30 years or more with basic maintenance, though seals and hardware can wear sooner than the frame itself. Proper installation matters as much as the window product, since a well-made window installed poorly will still leak air and moisture.
Do new windows really lower energy bills?
Replacing old, inefficient windows generally does reduce heating and cooling costs, though the exact savings depend on your home’s overall insulation, how many windows you replace, and your current windows’ condition. Homes with very old single-pane or failing double-pane windows tend to see the most noticeable difference.
