Find the Right Fix for Drafty Windows

Does your home have old, drafty windows that need a remedy? First, prepare yourself for a bit of sticker shock when you get your first bid for replacing windows. To help decide if replacement is indeed the right move, you’ll want to consider a few factors.

Increased Comfort

Any chill felt near windows when it’s cold out is likely due to radiant heat loss. When you’re near a cold surface, such as a window, you can feel chilled even if the temperature inside your home is over 70 degrees. Your body is much warmer than the surface of the window, and heat radiates from warm to cold. The inside surface of an inefficient, single-pane window will be much colder on a winter night than that of a double- or triple-pane window.

Curtains can be an affordable strategy to increase comfort and reduce energy use.

Window coverings are one unique approach to increasing the comfort level of your home. Curtains and blinds are very effective at reducing radiant heat loss in the winter and can even block some unwanted heat gain in the summer.

Another aspect to comfort is the sun. If you have cold winters but lots of winter sunshine, you might enjoy the comfort and warmth of the sun streaming through your windows on a cold clear day. If that’s the case, you should take this into consideration as you ponder window replacement. Some windows are better at letting the sun’s heat into the home than others.

Appearance and function

Since your windows are older, new wood- or vinyl-framed windows can act as an exterior facelift. But keep in mind, if you own an older home with classic wooden windows, vinyl replacements might look out of place. It’s possible to buy new windows that match the style of some older wooden windows, or you could decide to apply a little elbow grease to get them back into shape. Wooden windows, even if they were built before 1960, can last the life of the home.

Windows can provide ventilation, which sometimes improves comfort more cost-effectively than air conditioning. Windows also need to be cleaned occasionally. If your existing windows don’t provide ventilation or they are hard to clean, replacing them could solve these problems.

Resale value

Windows are a major point of interest for most prospective homebuyers, which is why we often hear that window replacement is good for resale value. But a 2019 study by the National Association of Realtors found that on average across the United States, installing new vinyl windows costs about $22,000 per home but only increased resale value by $16,500. Only 4% of realtors said the new windows helped close the sale, so if resale value is your main objective, the costs could likely outweigh the return on investment.

Energy savings

Homeowners often believe the best way to reduce energy use is to replace their windows, but this is rarely true. Companies that sell new windows sometimes advertise greater energy savings than the new windows can actually deliver. The amount of energy you save really depends on the efficiency of your existing windows compared to the efficiency of the replacement windows. An energy auditor can estimate potential savings, but most audits show that there are much more cost-effective efficiency investments than replacing windows.

On average, according to Energy Star®, replacing single-pane windows in a 2,000 square-foot home with Energy Star-certified windows will produce an average savings of $125 to $340 a year, depending on where you live. At this rate, it would take a decade or more to pay off your initial investment.

Replacing old windows can provide a number of benefits, but it’s a costly endeavor. By considering these factors and how long you plan to live in the home, you’ll be able to make the right decision.
