5 Signs Your Windows Need Replacing (Don't Ignore #3)
Your windows don't fail all at once. They deteriorate gradually — and by the time most homeowners notice, the problems have been costing them money and comfort for years. Here are the five most common warning signs that your windows need replacing, ranked by how often we see them in Spokane-area homes.
You Feel Drafts Near Closed Windows
This is the most obvious sign, and one that Spokane homeowners notice most during our cold winters. If you can feel cold air moving near a closed, locked window, it means the seals have failed, the weatherstripping has deteriorated, or the window frame has warped enough to create gaps.
A simple test: hold a lit candle or a thin piece of tissue paper near the edges of your closed window on a cold day. If the flame flickers or the paper moves, air is getting through. In Spokane's winter climate, even small drafts can significantly impact your comfort and heating costs.
Drafty windows force your furnace to work harder and run longer, which shows up directly on your Avista bill. Replacing drafty windows with properly sealed, energy-efficient replacements eliminates this problem immediately.
Condensation or Fogging Between Panes
If you see moisture, fog, or a milky haze trapped between the glass layers of your double-pane windows, it means the hermetic seal between the panes has failed. This is one of the most common window problems in the Spokane area, and it's not just a cosmetic issue.
When the seal fails, the insulating gas (usually argon) that was trapped between the panes escapes and is replaced by regular air. This dramatically reduces the window's insulating performance — often by 30-50%. The moisture you see is condensation forming because the window can no longer maintain a proper thermal barrier.
Unfortunately, there's no reliable way to repair a failed seal. The window unit needs to be replaced. The good news is that modern windows use significantly better seal technology and are far less likely to experience this problem.
Your Energy Bills Keep Climbing
This is the sign most homeowners overlook — and it's often the most expensive one to ignore. If your heating and cooling costs have been steadily increasing over the past several years (beyond normal rate increases), your windows may be a major contributor.
Windows account for 25-30% of residential heating and cooling energy use according to the U.S. Department of Energy. In Spokane's climate, with winter temperatures regularly dropping into the teens and summer highs in the 90s, that percentage can be even higher with older, underperforming windows.
Here's a rough calculation: if your annual heating and cooling costs are $3,000 and your windows are responsible for 30% of that energy loss, you're spending $900 per year on energy that's literally going out the window. Over 10 years, that's $9,000 — more than enough to pay for a full set of energy-efficient replacement windows.
Modern triple pane windows with Low-E coatings can reduce window-related energy loss by 40-60% compared to older double pane windows, and by 70-80% compared to single pane windows.
Windows Are Difficult to Open, Close, or Lock
Windows that stick, jam, won't stay open, or won't lock properly aren't just annoying — they're a safety and security concern. This problem is especially common in older Spokane homes where wood frames have swelled from moisture exposure, or where painted-shut windows have been a recurring issue.
Difficulty operating your windows can indicate several underlying problems: frame warping from temperature cycling, balance mechanism failure in double-hung windows, track damage in sliding windows, or foundation settling that has shifted the window frame out of square.
Beyond the inconvenience, windows that don't lock properly are a security vulnerability. And windows that won't open are a fire safety hazard — building codes require operable egress windows in bedrooms for emergency escape.
Visible Damage, Decay, or Outdated Appearance
Cracked glass, rotting wood frames, peeling paint, warped vinyl, or water stains around the window frame are all clear indicators that your windows have reached the end of their useful life. In Spokane's climate, where windows endure freeze-thaw cycles, intense UV exposure, and occasional wind-driven rain, exterior deterioration is common on windows older than 15-20 years.
Water stains or discoloration on the wall below or around your windows can indicate that water is infiltrating past the window seal — a problem that can lead to mold growth, structural damage, and significantly more expensive repairs if left unaddressed.
From a purely aesthetic standpoint, outdated windows are one of the most visible features of an aging home. Builder-grade windows from the 1980s and 1990s look dated compared to modern window designs. New windows can dramatically improve your home's curb appeal and are consistently rated as one of the highest-ROI home improvements for resale value.
How Many Signs Apply to Your Home?
If you recognized one or two of these signs, your windows are likely underperforming and costing you money. If three or more apply, replacement should be a priority — the longer you wait, the more you'll spend on energy and the greater the risk of secondary damage like mold or structural issues.
