LocationsHow to Know When to Replace Your Windows

If you’ve got a broken window or there’s visible damage to a window frame on the exterior or interior, it’s time for replacement windows. Broken windows are dangerous, and any opening can allow water to seep in, which can lead to mold and mildew issues. Damaged window frames can also invite pests, and some pests, like termites, can severely damage a home.
If you notice any water stains or signs of wood rot on window frames, it’s time to replace your old windows. Wood rot is either white/wet rot, brown/dry rot, or soft rot. White/wet rot is whiteish or light yellow and will feel spongy. Brown/dry rot turns wood into a deep brown color. Soft rot leaves a honeycomb-like appearance on wood and is mostly found on fallen trees. But if conditions are right, like extreme temperatures, it can appear in homes.
If your windows look dated, or you want a home makeover, then investing in new windows is a good idea. If you plan to renovate your home, it’s also a good time to change your old windows. You might want a bigger view in a room that has double hung windows. That can lead you to adding picture, casement, or awning windows to capture bigger views. People often like to swap out windows with patio doors for more functionality, natural light, and wider views. Crank windows also might be easier to operate for some people than double hung windows that need lifting to open. Homeowners can recoup 61-68% of a window replacement cost when you sell your home.
When the temperature difference between the indoor and outdoor panes of glass increases and the humidity in your home reaches certain levels, windows and doors start to show condensation. Condensation is an accumulation of saturated warm air on a cooler glass surface.
Condensation on the outside of your windows should not raise alarm. If you notice condensation on the inside of your windows, it means your windows are leaking air and/or your home is humid.
If you see condensation between the panes of glass in your double or triple-pane windows, or have foggy windows, it means that the air-tight seal has failed, and insulating gas has escaped. You can check your manufacturer’s warranty to see if seal failure is covered. If it’s not covered, you might need to replace your windows.
If you can hear a slight whistle around your windows, you likely have a draft. You can also check for drafts by holding your hand at the top or bottom of the window sash where it meets the frame. If you feel air on your hand, you have a drafty window.
If your windows won’t open or close easily, it’s time to replace them. Using a book to keep a window propped open isn’t a long-term solution for old windows. The years of opening and closing windows do add up and can eventually cause cracks on the window frame. Dust and dirt can accumulate as well and make windows difficult to open and close. A poorly functioning lock can prevent proper sealing. It can be one of the first signs that it’s time to replace your windows.
One of the best reasons to replace windows is if your energy bill is through the roof. Energy efficient windows can help save you money.* The National Fenestration Rating Council (NFRC) estimates the average American household spends $1,500-$2,500 annually on energy bills. Around 45% of that goes toward heating and cooling costs.
ENERGY STAR® estimates a homeowner can save between $493 and $568 a year on average, if they’re replacing single pane windows with ENERGY STAR-certified windows. When replacing double pane clear windows, those savings range between $253 and $373.* New windows are one of the ways to reduce energy loss.
