Many homeowners have the misconception that installing windows or patio doors in the winter is a bad thing, and they hold off because they are afraid too much cold air will get in the house or they will get a poor installation. It’s not true. It doesn’t really matter when the window or door is installed. In winter, the installation might take a little bit longer installers are taking care not to leave openings exposed for too long. In reality, the opening will only be exposed to the weather from 20 minutes to an hour.
The same is true with doors. The process goes fairly quickly, because new products are all prepped for installation ahead of time. The old window is taken out, the opening is cleaned and any rotten wood is carefully replaced. The window is then placed into the opening, leveled and secured. If there are multiple windows involved, winter installation is done one at a time to reduce potential heat loss. In the summer, of course, multiple windows can be taken out at once. Does my Window Need to be Replaced?
If you can feel air coming in, or a draft, it’s definitely time to replace your windows. If you have a double pane glass and in the morning there is condensation between the two panes of glass, you have a seal failure, which means that the windows are not working as efficiently as they should. If there is condensation on the interior pane and not between the glass, you have a moisture issue that needs to be addressed. The moisture level of your house should be between 30 and 32 percent humidity. Otherwise you risk hitting the dew point, which results in condensation forming, much like condensation forms on a mirror in a steamy bathroom.
Tip: If you have blinds, don’t close them all the way. Leave them open about two inches from the bottom to allow warm air to wash over the glass, which will help condensation from occurring.
