Windows questions, answered by experts

Replacement windows normally don’t come with new sills, as the sill is part of the window frame that the replacement window fits inside. If you’re replacing windows, it’s a good idea to replace the sill, as well, especially since the sill will be fully exposed and easily accessible for replacement.

Actually, condensation can mean that your windows are more energy efficient because the seal keeps cold air out and warm air in. In some cases, windows with poor seals can lead to more condensation, but they may allow the cold and warm air to mix and reduce condensation. If you’re worried about whether or not your windows are properly insulated, have a pro assess them.

Most manufacturers have their name imprinted somewhere on the window, such as the spacer bar, hardware, or frame. Other manufacturers will include an identification number printed on the glass itself. If you’re unable to find either of these, then your window was manufactured locally (oftentimes called a “shop window”). 

With a manufacturer name (or even better, the identification number) you can attempt to research the information to find out when the product was made. Keep in mind this won’t tell you when the window was installed on your home, but can get you close.

Most properly installed and maintained windows last between 15 and 20 years. Fiberglass windows last much longer than your average window. Since they don’t warp from temperature changes, rust, or rot, you might be able to hold onto fiberglass windows for up to 40 years. On the other hand, poorly maintained wood windows may only last for a few years.

Late spring through early fall is the best time of the year to replace windows. Ideally, you’ll want warm temperatures and minimal rain. Demand can be high just before summer and winter, though, so be sure to schedule well in advance to get your windows replaced before extreme temperatures arrive.
