Windows rarely fail all at once. They wear out slowly, and the symptoms are easy to blame on something else: the AC, the weather, the house settling. If two or three of the signs below sound familiar, your windows are probably the cause, and replacing them is worth a closer look.
1. The glass looks foggy and will not wipe clean
Insulated windows have two panes of glass sealed together with a space between them. When that seal fails, humid air gets inside and leaves a haze, streaks or droplets you cannot reach from either side. You may notice it most on cool mornings or after a run of hot, humid days.
A failed seal means the window has lost much of its insulating ability, and the view only gets worse over time. Some people try to have just the glass replaced, which can work on newer windows in good shape. If the frames are old as well, replacing the whole unit usually makes more sense.
2. Rooms near the windows stay hot in the afternoon
Austin summers are long, and a west-facing room with old glass can feel like an oven by four o’clock even with the AC running. Hold your hand near the glass on a sunny afternoon. If it radiates heat like a stovetop, the window is letting in a lot of solar energy.
Other clues: the thermostat says one thing but the back bedroom feels several degrees warmer, the AC seems to run constantly in July and August, or furniture and rugs near the windows have faded. Older single-pane glass and early double-pane units without a low-E coating are the usual culprits. Newer glass is designed to cut solar heat gain while still letting daylight in.
3. Sashes stick, or you can see light around the frame
A window that used to slide easily and now takes two hands, or a lock that no longer lines up, is telling you something has moved. Parts of the Austin area sit on expansive clay soil that swells when wet and shrinks during dry spells. As the house shifts, openings can rack slightly out of square, sashes bind, and small gaps open up between the frame and the wall.
Look at your windows from inside at dusk with a light on outside, or check for daylight around the edges during the day. Also look for soft or crumbling wood on sills, peeling paint that keeps coming back, or water stains on the drywall below a window. Any of these can mean water is getting into the wall, and that should be dealt with promptly.
4. Dust and pollen collect on the sills
If you wipe the windowsills and find a fresh layer of grit a few days later, air is getting in around the windows. In Central Texas that air carries cedar pollen through the winter, oak pollen in spring, and limestone and construction dust in neighborhoods where building never seems to stop. Allergy sufferers often notice the difference first.
Worn weatherstripping and gaps around the frame are the usual paths. New weatherstripping can buy time on a window that is otherwise sound. On an older window with worn tracks or a loose sash, a replacement with tight seals and good screens does a better job of keeping the outdoors outdoors.
5. You hear more of the outside than you used to
Traffic on I-35, MoPac or US 183, planes on approach to the airport, weekend crowds downtown, a construction crew on the next lot over: if these sounds come through clearly, your windows are part of the reason. Old single-pane glass and loose sashes let sound in through the glass and around the edges.
Replacement windows with insulated glass and tight seals can make a real difference, especially in bedrooms. If noise is your main complaint, say so during your estimate, because some glass options are better suited to sound control than others.
Other things worth noticing
A few more signs do not make the top five but still matter. Water beading on metal frames on cold mornings, grids that have come loose inside the glass, cranks or balances that no longer hold a sash open, and windows that have been painted shut for years all point the same direction. So does planning to sell soon, since dated or damaged windows are one of the first things buyers notice.
Repair or replace?
One problem on one window can often be fixed. A worn balance or a torn screen does not justify a new window. When several windows show several of these signs, though, piecemeal repairs tend to cost time and money without solving the underlying issue. That is usually the point where replacement makes more sense. You can see the styles we install on our replacement windows page.
